    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.

    @patrickpoeschl2966 4 роки тому +1

    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.

  • @timturner8754

    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'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.

    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.

      @@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. If you can't offer a constructive or helpful reply, don't reply at all.

    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..

    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.

    • @opl500
      @opl500 6 років тому

      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.

  • @speedstyle.
    @speedstyle. 2 роки тому

    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

  • @Hjossi88
    @Hjossi88 6 років тому

    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.

    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.
