This is a good method. I use an old sniper trick I got from an old book on shooting. sin 10 = 1/6, sin 20 = 1/3, sin 30 = 1/2, sin 40 = 2/3, sin 50 = 3/4, sin 60 = 7/8, sin 70 = 15/16, sin 80 = 1, sin 90 = 1. You have to commit to memorizing the number but once you do that you just go straight to the answer.
I have watched all of your videos in the past 24 hours. You are a gem. I start my PPL tomorrow with American Flyers in addison TX. I want to become a commercial pilot and fly for the airlines. Keep up the good work.
@@74gearthank you so much! I am 13, just started my training. I’m doing 1 lesson per month until I’m 16 when I can solo. Then I will start to take it seriously. I know I’m 5 years late, but I just wanted to express my gratitude for you! Thank you Kelsey!
This was so helpful, and I’m terrible at math. I got 9 kts of crosswind! Thank you! (Also, the 747 is my favorite aircraft, so that’s awesome! Queen of the skies!)
SWEET, All my years of flying including checkouts and flight reviews no one has ever shared that with me. As a PPSEL I would listen to the weather, but still fly over the field to look at the sock. Great tip, and as Pro you don't have that luxury. Really enjoying your videos.
Good tip. I use a lot more WAG (Wild A$$ Guess) in my mental math while I'm hand flying, though.. In my case, if the wind is not directly down the runway or a direct crosswind, I round it to 30, 45, or 70 off runway heading. For 30, the crosswind is 1/2 the velocity. For 45, it is 2/3 the velocity. For 70, it is 90% of the velocity. That gets me close enough. Of course if I suspect it will be near a limit, I pull out a chart to make sure I'm legal. My WAG gave me 9 kts crosswind for your example.
Thanks for the interesting and informative videos. Cute linear estimate of sine function. It fails at low and large angles. You mentioned the high angle correction: if 80 degrees or greater (sin ~ 1) just use the full wind speed. The low angle correction is also easy. If the difference angle a is less than 20 degree, divide angle by 10 then MULTIPLY by 2 (that is, 2(a/10)). This is just a little different than your middle angle estimate: divide angle by 10 then ADD 2 (that is, a/10 + 2).
I have really been struggling with finding a crosswind component calculation method that works for me (while in the air). Thank you for sharing this. This works for me 👍
Thank you so much, you make it really simple!!! If you have more aviation related math tricks, please share them if you have the time. Im learning for my ppl written exam and I really apreciated this video ;) keep up the awesome video's 74 Gear!!
9 is the crosswind component. Wow sir this is a nice way to calculate! I can assure you I did not cheat and the answer came in less that 10 seconds and with some more practice it will most probably improve. Thanks a lot!
3 + 2 =5 5 x 2 = 10 Around 10 kt component. Thanks bro, I’m in my last days of commercial pilot hours but I have been struggling with this I have an small test tomorrow in 737 simulator at school it is gonna be all about crosswinds. This helps a lot.
I’ve been watching your videos for fun, never knew you did there education type videos! Thanks a lot , I’m doing my PPL navigation exam soon. You helped me out a lot)
I've loved aviation ever since I was a teenyweeny little one. I wanted to be a pilot when I was in high school (well, wanted to be a pilot in the USAF actually) but Dad said no to enlistment, as I was too young to do it myself at the time. Got into the airline industry at the local int'l airport, then, after a few years, went inflight. I'm now in the finance industry, (inflight OJI) Miss my flying days and still dream of being a pilot but this whole MATHS thing is scary!! And I LOVE learning!! :) You did make it less intimidating though. Even though this is one of your HELLA OLD videos, it helped minimize the fear. Thanks for sharing your tips @74Gear !!

In 1971 I had about 15 hours in a Cessna 150. My weather pre-flight was a little abbreviated. A weather front came in while I was out drilling holes in clouds.. The wind had increased from 25 knots with peak gusts to 39 knots from 350 degrees. Tower gave me runway 30 so I crabbed in while being buffeted like I was on a brahma bull. As I straightened out to touchdown a gust blew me off to the left of the runway - no damage other than my nerves. The overly calm tower person said in a slow southern drawl, "Cezzna 1234 continue to your parking area".
The aproximation sin (alpha in degrees) = (alpha in degrees/10 +2)/10 for the crosswind component seems to be close enough for an crosswind between 20 and 90 degree. Nice idea a good calculation scheme for the crosswind. I may use it to approximate the drift of my sailing ship by current and wind. Alpa/sin (alpha)/approximation 00/0,00/0,2 10/0,17/0,3 20/0,34/0,4 30/0,50/0,5 40/0,64/0,6 50/0,76/0,7 60/0,86/0,8 70/0,93/0,9 80/0,98/1,0 90/1,00/1,1
What about the gusts? Sustained wind of 15 knots but gusts up to 30? How do you adjust for that? Always so happy having such smart hard working pilots.
My instrument instructor always told me to KISS (keep it stupid simple). I got 9 knots on this one. I just look at the .8 as a percentage. Luckily this one falls within a whole number, lol. Awesome! Thanks for the tip!
Crosswind formula is Crosswind = wind speed x (sine). For me, the clock method works best. Picture a clock: 15 minutes = 25%, 30 minutes = 50%, 45 minutes = 75%, 60 minutes = 100%. In the test question, the difference between runway 9 and the wind direction is 30 degrees (30 minutes on the clock). 30 is half (50%) of 60; half of 18 knots is 9 knots. This method is more accurate as the (sine) of 30 is .5 or 50%. Take the previous example again: Runway 9 with 50 degrees. 50 minutes is 80% of 60. 80% of 10 is 8 knots.
Just used this on my daily IFR flight plan (proficiency practice planning) rwy 31 wind 360@8 DIff 50 > 5 >+2>7 wind 8 >.8 > 7x.8= 5.6 x wind from right.
@@johnhorvath9878 Heading is 090 - drop the zero call it 9. wind is 060, drop the zero call it 6. 9 (hdg) - 6 (wind dir) = 3. Add 2. ALWAYS add the 2 no matter what, to the difference between those numbers. Just accept you add 2 at this point of the calculation. It could be 25 - 18 ( = 7 + 2 ) or 12 - 4 ( = 8 + 2) any numbers - you just add 2. So, now back to our friends 74Gear example in his video you have 5. Now the wind strength is 18 knots.. make it simple, call it 20 knots, and now again drop the zero (so 2) Take your 5 (which we got from the first (hdg - wind) + the 2 (that ALWAYS gets added there) (so we get 9 - 3 + 2 = 5 at this point) and multiply by the wind speed (which you've over corrected for slightly in our case it is 2) so 5 x 2 =10. Because you slightly overcorrected on the windspeed (by rounding 18 kts to 20 kts (we dropped the zeros remember) to make the numbers simple rather than having to multiply by 1.8 we multiplied by 2 - we take a knot off. If the speeds were higher we might take off 2. So we get around 9kts. It's not exact but good enough for a quick calculation. It's a rule of thumb - like getting Celsius/Centigrade to Fahrenheit has a formula based on (°C × 9/5) + 32 = °F. Who has the mental maths for that everyday? Double Celsius and add 30. Fahrenheit to Celsius? Then - 30 and halve. Is it scientifically perfect? No, but it's close enough for quick numbers. Hope this helps you or anyone else - more than the other reply you received, which was "no". I don't understand people sometimes.

Hi, you know what? Some of the smart Alecs out there don’t know this. Me (sheepishly acceptin’) learnt this after 10k hours. Thank you very very very much.
Another way to visualize the crosswind component; The wind calculator on the back of an E6B very closely resembles a DG or HSI. Once you understand how to use the E6B wind calculator, visualize the E6B wind calculator over your DG or HSI to guesstimate the value of the crosswind component based on your current heading and wind direction..
Nice video. I learned almost the same way. I just take the difference then add 20. This is then the % of the mean wind. So in your scenario: RWY 09 wind 60 = 30 degrees. Plus 20 = 50% of mean wind which is 18 = XWC is 9 👍🏻😁
Hi Kelsey,I saw your comment on Captain Joe's video and decided to subscribe and learn more things from your videos. They are really good and I am very excited to see the content you will put out in the future! Thank you for putting out the great content.
Hi Kelsey, Sorry for such a late reply. I am currently in an Integrated Airline Transport Pilot's License Program. I have my Private Pilot's License and am currently working on my night rating and have been flying since I was 15. I have mostly been flying out of the Brampton Flight Centre just northwest of Toronto Canada. Thank you for having me be a part of the 74 Crew.
74 Gear Negative, I attained my PPL and I am currently working on sitting for my ATPL theory exams and start my CPL/ME/IR/MCC training respectively. Thank you for touching base with me!
My eyes glazed over just like they did in high school. This is why us dyslexics don't tend to get into the airline industry I guess. ;-) When we were landing in a cessna in Panama, I used to look at the wind sock, times were simpler.....
74 Gear The FBO that we flew out of is now a mall, apparently Oceanside property was more valuable than GA was. Fun fact, back in the 80’s they would mark up your chart with a red “X” so that you wouldn’t land in a place likely to get you murdered and your plane a new job as a drug runner. ;-)
@@74gear I have a video called "1987 Panama Flight Paitilla field" , if you FF up to 3:34 we land on a strip thats so short, we had to get out, and turn the plane by hand for the take off. Missed approach needs to be dealt with in about .223 of a second. ;-) In parts of the video you can see the dash falling apart on our rental, it also had a microphone wire into the dash at one point that you had to hold by hand. Wild west is an excellent description.
@@74gear Yea, that doesn't sound like much fun. The guy I went out with always flew VFR, he was IFR qualified, but the rattle trap rentals were easier to crash during the day when you could see. ;-) (Kinda kidding on that.... kinda....)
Wow, just found this.. as I am studying for my ground school exam. Thank you much! I’ll try to remember it. (Also need to remember how to follow the chart hehehe)
Dude you are the best. I am an aviation enthusiastic. I love studying about aircrafts. I just have one question, please make a video on how to become a pilot and all the expenses that are needed.
Back in 2017 Dutch Engineer Hans Hesselink proposed the use of circular runways. Can you show us the mental calculus necessary to determine the crosswind component for each moment of the landing? I presume landing in the middle of a twister would be a doddle.
Great video Kelsey! You have a great channel with great content. It reminds me a lot of captain joe and mentor pilot. You definitely deserve more subscribers! Keep it up man !
Hi Kelsey, completely unrelated to this video question. Do you shut down some of the engines after landing once taxiing to the gate and clear of all active runways? If no, why? And for departure, why all 4 engines have to be started before taxiing, why can’t numbers 1 and 4 be started before and 2&3 somewhere close to holding point to save some fuel? Thanks :)
Have you ever landed in a 30 knot crosswind? Or even the 14 kt one? My old instructor just used the trig identities and guessimated if it was between them. I think 30 deg is 1/2 and 60 deg is .8 or so. A 15 knot wind of any kind is pretty stiff in a small plane in any case. What you call interesting, I guess. I'll have to file this one away tho.
Oh that one's easy, you made it 30 degrees, it's 1/2, so 9 kts. If it was something else, I'd have to fudge it. :P I'm guessing your favorite method of dealing with xwind is crab and kick? I know some old school guys like to do the one wheel touchdown.
Right now, nuttin' I spent 99% of my time in a Cessna 172 and did about 6 hours in a Duchess for multiengine. I want to build either an RV-12 or a CH 650 and hire someone to get my instrument and then either a commercial or an ATP.
I'd have to get out the logbook but around 150 hours. I was about halfway to an instrument rating when I had to quit. Procedure turns, holding patterns was what I remember tying me up in knots. DME arcs were relaxing for some strange reason.
Hey 74 gear I watched your video explaining wake turbulence,but how do fighter jets overcome this?? Because i have seen jets flying real close in different formations..
This is basically (x+20)/100. You can compare it to sin(x deg), it's way too big for small angles (where the wind is mostly head/tail) and too small around 60. You could do way more complicated math to fix this, or just remember to round up a bit around 60
30 degrees = 50% wind component 45 degrees 70% wind component 60 degrees 90% wind component My rule of thumb. To be really strict 60 degrees is 87% and 70 degrees is 93% but the other way you’re being conservative and all over 70 degrees I consider full crosswind.
Hi Kelsey, I've got a question: Is this a quick X-wind calculation for (commercial or GA), flying the Circuit (GA) has no time for this. What about variable winds? Do you have a simplified version?
Is he just taking the bigger of the two numbers associated with wind and subtracting it from the runway? Also the wind number is it based on the direction of a compass??
Hello I have a problem with this, wind 230° and landing runway 04 the difference is 190, now I must to move the decimal point back 2 spot in this case right?
Do you think that the 747 has a future in civil aviation? Because on the one hand many airlines already started to retire their passenger jumbos, but on the other hand they get popular again as a freighter. Am I wrong please tell me. Best wishes (p.s. Sorry for my bad english)
@@74gear Thank you for the answer. Unfortunately I never had the chance to get on a flight operated by a 747. I really like the 747 because after the first airlines started to use the queen of the skies It kind of changed the way people were flying (long haul) , so I am hoping that I get on a 747 flight one day. (maybe Lufthansa since they still operated many jumbos)
@@74gear I think it is a little sad that those Airlines retire such a beautiful plane, but Lufthansa for example will replace it with the 777X I guess, wich is a pretty impressive plane too, isn't it ? I am exited to see those huge engines on that plane. By the way your Story is funny. I assume it is more exciting to fly it as a pilot anyways :)
@@74gear I am a planespotter in Dresden, germany. Last year I had the great opportunity to see a - 8 performing a lowpass at EDDC and it was spectacular, when that huge plane suddenly appeared out of the fog. It was the day, when Lufthansa launched their new livery.
Ooh I get it. When I draw a circle with the runway inside of it it is a lot easier. I use sinus to get the result. Sin(30°)=X/18knots => X= sin(30°)×18= 9. Personnaly this is a lot easier. Is 9 right?
Okey thanks mate. I am 17 and want to get my PPL next year so I am trying to prepare me for the selections. Because there are just 11people who can pass the test. Do you have tips to prepare the selection? I live in Brussels so I want to fly at Zaventem. My english is not bad so I hope I pass the selection.
Hey Kelsey, Love your videos But what if the wind is variable What do you calculate or do you calculate the wind component with. Which exact degree from the wind will you use. I hope I get an answer . Thanks in advance :D *KEEP THE BLUE SIDE UP*
This is a good method. I use an old sniper trick I got from an old book on shooting. sin 10 = 1/6, sin 20 = 1/3, sin 30 = 1/2, sin 40 = 2/3, sin 50 = 3/4, sin 60 = 7/8, sin 70 = 15/16, sin 80 = 1, sin 90 = 1.

Cute linear estimate of sine function. It fails at low and large angles. You mentioned the high angle correction: if 80 degrees or greater (sin ~ 1) just use the full wind speed. The low angle correction is also easy. If the difference angle a is less than 20 degree, divide angle by 10 then MULTIPLY by 2 (that is, 2(a/10)). This is just a little different than your middle angle estimate: divide angle by 10 then ADD 2 (that is, a/10 + 2).

Crosswind formula is Crosswind = wind speed x (sine). For me, the clock method works best. Picture a clock: 15 minutes = 25%, 30 minutes = 50%, 45 minutes = 75%, 60 minutes = 100%. In the test question, the difference between runway 9 and the wind direction is 30 degrees (30 minutes on the clock). 30 is half (50%) of 60; half of 18 knots is 9 knots.
This method is more accurate as the (sine) of 30 is .5 or 50%. Take the previous example again: Runway 9 with 50 degrees. 50 minutes is 80% of 60. 80% of 10 is 8 knots.

You'll have 9 knots of crosswind component
So are we adding 2 to the diffrence cause it's 20knots?
@@johnhorvath9878 no
@@johnhorvath9878 Heading is 090 - drop the zero call it 9. wind is 060, drop the zero call it 6.

Because you slightly overcorrected on the windspeed (by rounding 18 kts to 20 kts (we dropped the zeros remember) to make the numbers simple rather than having to multiply by 1.8 we multiplied by 2 - we take a knot off.

I have my Private Pilot's License and am currently working on my night rating and have been flying since I was 15. I have mostly been flying out of the Brampton Flight Centre just northwest of Toronto Canada. Thank you for having me be a part of the 74 Crew.
Thanks man I want to be a pilot when I grow up
awesome well that video has some really simple math you can use so I am glad you liked it.
xwind is 9. thanks for the examples, very neat. appreciated greatly also for a hold tutorial.
I feel smart😎
Dear Captain: Good day! I am loving all your videos, they are very informative and have a funny twist. Keep up your great work!
74 Gear Negative, I attained my PPL and I am currently working on sitting for my ATPL theory exams and start my CPL/ME/IR/MCC training respectively. Thank you for touching base with me!
74 Gear I sure will
74 is a FO, First Officer. Captains have 4 stripes.
Do you then add the crosswind component to your Vref speed in some way depending on runway conditions?
My eyes glazed over just like they did in high school. This is why us dyslexics don't tend to get into the airline industry I guess. ;-) When we were landing in a cessna in Panama, I used to look at the wind sock, times were simpler.....
74 Gear I was just a heading holder, my pilot was an x navy guy that lived island hopping.
74 Gear The FBO that we flew out of is now a mall, apparently Oceanside property was more valuable than GA was.
Fun fact, back in the 80’s they would mark up your chart with a red “X” so that you wouldn’t land in a place likely to get you murdered and your plane a new job as a drug runner.
;-)
@@74gear I have a video called "1987 Panama Flight Paitilla field" , if you FF up to 3:34 we land on a strip thats so short, we had to get out, and turn the plane by hand for the take off.
Missed approach needs to be dealt with in about .223 of a second. ;-)
In parts of the video you can see the dash falling apart on our rental, it also had a microphone wire into the dash at one point that you had to hold by hand. Wild west is an excellent description.
74 Gear Yea, that would be tocumen? I flew out of there just before the invasion.
(So I left before it got too exciting....). ;-)
@@74gear Yea, that doesn't sound like much fun.
The guy I went out with always flew VFR, he was IFR qualified, but the rattle trap rentals were easier to crash during the day when you could see.
;-) (Kinda kidding on that.... kinda....)
Wow, just found this.. as I am studying for my ground school exam. Thank you much! I’ll try to remember it. (Also need to remember how to follow the chart hehehe)
Dude you are the best. I am an aviation enthusiastic. I love studying about aircrafts. I just have one question, please make a video on how to become a pilot and all the expenses that are needed.
@@74gear Thanks captain. I watched that video and I will keep following you in future.
Back in 2017 Dutch Engineer Hans Hesselink proposed the use of circular runways. Can you show us the mental calculus necessary to determine the crosswind component for each moment of the landing? I presume landing in the middle of a twister would be a doddle.
Excellent, thanks!!
@@74gear yes, Thanks!
That was amazing thank you . I’m student pilot. It was so good captain. Thank you 🙏🏻
Excellent!!!!!
hi, it would be very cool if you could make a tutorial on holds, and using the correct entry pattern. in an effective way for learning !!
Good method. Thanks :-)
CONGRATULATIONS ON 600 SUBS!!!one question tho do you ever get bored of flying airliners?
@@74gear Dude everyone will love it if you do a live q&a! At least I know I'll watch it!
@@74gear Hey... 3 months later and you have 20k+ followers! Congrats! Thanks for the great content
Great video Kelsey! You have a great channel with great content. It reminds me a lot of captain joe and mentor pilot. You definitely deserve more subscribers! Keep it up man !
this is great but can someone explain to me where the +2 is coming from I am lost. thanks
Great video albeit 5 years ago, still very helpful ... not the first to ask, what formula do you use if there are gusts?
Hi Kelsey, completely unrelated to this video question. Do you shut down some of the engines after landing once taxiing to the gate and clear of all active runways? If no, why? And for departure, why all 4 engines have to be started before taxiing, why can’t numbers 1 and 4 be started before and 2&3 somewhere close to holding point to save some fuel? Thanks :)
@@74gear thanks heaps for the explanation!
Have you ever landed in a 30 knot crosswind? Or even the 14 kt one? My old instructor just used the trig identities and guessimated if it was between them. I think 30 deg is 1/2 and 60 deg is .8 or so. A 15 knot wind of any kind is pretty stiff in a small plane in any case. What you call interesting, I guess. I'll have to file this one away tho.
Oh that one's easy, you made it 30 degrees, it's 1/2, so 9 kts. If it was something else, I'd have to fudge it. :P I'm guessing your favorite method of dealing with xwind is crab and kick? I know some old school guys like to do the one wheel touchdown.
Right now, nuttin' I spent 99% of my time in a Cessna 172 and did about 6 hours in a Duchess for multiengine. I want to build either an RV-12 or a CH 650 and hire someone to get my instrument and then either a commercial or an ATP.
I'd have to get out the logbook but around 150 hours. I was about halfway to an instrument rating when I had to quit. Procedure turns, holding patterns was what I remember tying me up in knots. DME arcs were relaxing for some strange reason.
Pretty cool.
Hey 74 gear I watched your video explaining wake turbulence,but how do fighter jets overcome this?? Because i have seen jets flying real close in different formations..
It’s probably because wake turbulence is dependent on weight, and as a fighter is much lighter, they have less problems
And if you have :
Rwy03 wind 350° / 20 kts ? What gone be the answer?
About 10kts per your method. Another method I came across online is the clock method. 20deg 1/3x-wind, 30deg 1/2 x-wind, 40deg 2/3 x-wind and so on.
I think I came up with around 9 but but thats pretty close!
This is basically (x+20)/100. You can compare it to sin(x deg), it's way too big for small angles (where the wind is mostly head/tail) and too small around 60. You could do way more complicated math to fix this, or just remember to round up a bit around 60
30 degrees = 50% wind component
45 degrees 70% wind component
60 degrees 90% wind component
My rule of thumb.
To be really strict 60 degrees is 87% and 70 degrees is 93% but the other way you’re being conservative and all over 70 degrees I consider full crosswind.
NEVERMIND, 2:19 CLEARED IT UP.
glad you figured it out Clifff!
I just started PPL with cessna, and was wondering, doesn't 747 have wind direction display? or is it easier to compute than say look at the display
@@74gear thanks captain! appreciate much !!
LIKED im watching youre vid while im at school 😛
Watched it twice just for fun!
ohhhh we have different definitions of fun then 🤣
@@74gear Truly enjoy your videos.⚓
yet another, great technic.
But could please clarify where did you get +2 from?
how do you deal with winds below 10 knots? Wind speed 8 - .8?
Now i shall flex on my math teacher. Wish me luck!
Using your method I come up with 10. Is there a gust factor Calc you use ?
Why do you add 2 to the difference between runway hdg and wind direction? Where does that come from?
74 Gear Sure did. Thanks. Love the channel
Hi Kelsey, I've got a question: Is this a quick X-wind calculation for (commercial or GA), flying the Circuit (GA) has no time for this.
What about variable winds?
Do you have a simplified version?
That simple math really finds application in real life scenario. Nice!
Is he just taking the bigger of the two numbers associated with wind and subtracting it from the runway? Also the wind number is it based on the direction of a compass??
Hello Excellent video, thanks for this, I have a question, This can be used to calculate the crosswind component to the cruise?
I have been playing with your method and it great until I get to say Runway 33 and wind direction 030. Is it anything over 180 subtract from 360?
Hello I have a problem with this, wind 230° and landing runway 04 the difference is 190, now I must to move the decimal point back 2 spot in this case right?
Treat it as landing runway 22 ... and in this specific case, it had better be next to nothing, that's practically pure tailwind!
Do you think that the 747 has a future in civil aviation? Because on the one hand many airlines already started to retire their passenger jumbos, but on the other hand they get popular again as a freighter. Am I wrong please tell me.
Best wishes
(p.s. Sorry for my bad english)
@@74gear Thank you for the answer. Unfortunately I never had the chance to get on a flight operated by a 747. I really like the 747 because after the first airlines started to use the queen of the skies It kind of changed the way people were flying (long haul) , so I am hoping that I get on a 747 flight one day. (maybe Lufthansa since they still operated many jumbos)
@@74gear I think it is a little sad that those Airlines retire such a beautiful plane, but Lufthansa for example will replace it with the 777X I guess, wich is a pretty impressive plane too, isn't it ? I am exited to see those huge engines on that plane. By the way your Story is funny. I assume it is more exciting to fly it as a pilot anyways :)
One more Question. Which version/generation of the 74 is your favorite?
(p.s. Apologies for taking your time 😶)
@@74gear I am a planespotter in Dresden, germany. Last year I had the great opportunity to see a - 8 performing a lowpass at EDDC and it was spectacular, when that huge plane suddenly appeared out of the fog. It was the day, when Lufthansa launched their new livery.
Sorry it was this year 🤪
Nice video :)
What is the angle difference between the runway and the wind? I don't know how it Works with the last exemple you told us.
The last one you answered. I don't know how you get 70° angle difference if your wind comes from 250°.
Ooh I get it. When I draw a circle with the runway inside of it it is a lot easier. I use sinus to get the result. Sin(30°)=X/18knots => X= sin(30°)×18= 9. Personnaly this is a lot easier. Is 9 right?
Okey thanks mate. I am 17 and want to get my PPL next year so I am trying to prepare me for the selections. Because there are just 11people who can pass the test. Do you have tips to prepare the selection? I live in Brussels so I want to fly at Zaventem. My english is not bad so I hope I pass the selection.
74 Gear okey thanks! Keep up the good work!
In which airline are you working with
Hey Kelsey,
Love your videos
But what if the wind is variable
What do you calculate or do you calculate the wind component with. Which exact degree from the wind will you use.
I hope I get an answer . Thanks in advance :D
