- What is the Climb Gradient, why is it so important and how do you find the information about the minimum Climb Gradient required?
By definition, the Climb Gradient is the ratio between the distance traveled over the ground and the altitude gained expressed in percentage.
Every SID (Standard Instrument Departure) and every Missed Approach have a minimum climb gradient.
You have a minimum Climb Gradient on your departure procedure because you need to be separated by the obstacles and, in order to get this separation, you need to maintain a minimum rate of climb that varies from departure to departure depending on the terrain.
The same applies to the missed approach since you will execute the go-around at your minima which is, normally, closed to the ground.
So, once you know the minimum climb gradient of the procedure and, your aircraft climb gradient you will be able to figure it out if you can fly that particular procedure.
For example, if your Departure minimum climb gradient is 10% and your aircraft gradient is 5% this means that you are not capable to fly this Standard Instrument Departure.
A gradient of climb of 100% means that for every 100m of a horizontal distance you climb 100m, a 50% gradient means that for every 100m you climb 50m, and so on.
At the bottom of the graphic section of the SID chart, you find the Minimum Climb Gradient requirements expressed in percentage and in feet per Nautical Miles.
Next to it, you will be able to find out, depending on your climb Ground Speed, which rate of climb you have to maintain in order to comply with the minimum gradient.
On the approach chart, you will find the minimum missed approach climb gradient on the Decision Altitude table.
You then need to check on your aircraft tables if, depending on the weather and aircraft conditions, you can comply with the minimum climb gradient.

Don't hesitate to comment the video with your questions !!! Happy Landings!!!
Great Video, want to ask if this climb gradients are designed with all engines operating?
@@lexydeny4669 Hey, I hope you are doing great! Many thanks for watching!
The SID climb gradients are designed with all engine operative, and normally the minimum SID climb gradient is 3.3%.
The problem is that in case of an engine failure you might not be able to achieve this minimum climb gradient, so, for this reason, if you experience an engine failure on take off you don't fly the SID but the Engine Out Emergency Turn.
By following the engine out departure you will be separated from the obstacles with one engine out.
I hope I answered your question!
Happy New Year!

Easiest way i've learned was to multiple the groundspeed with the required min. climb gradient e.g : -> 200kts x 5,6% = 1120 feet per minute minimum climb rate
Many thanks for the comment! 👍
@@PILOTCLIMB thanks, maybe you can do a video with all the rule of thumb calculations. Keep up the good work
That's a great idea! Thanks
I’m in! Im a Captain for the A330 and any and all knowledge is very much welcomed! Please do the Rule of Thumbs video
Thank you. simplest way ever to put it. 100% climb gradient as a starting point.
Hello, many thanks for watching!! I'm happy you liked the video!!

i realize I am pretty randomly asking but does anyone know of a good site to stream new tv shows online ?
@Gregory Braylen Flixportal =)
@Amari Tyson thanks, I signed up and it seems like a nice service :) I really appreciate it!
@Gregory Braylen Happy to help :D
a very useful lesson many ignore during approach briefing! Next time I fly into high terrain region I will pay attention to the SID and MAP gradients and brief after checking perf WAT limits!! THANK YOU!
That's great!! Many thanks for watching!
Thanks a lot gives a clearer understanding in computing VFS for the HERCS
You are most welcome
I always learn a lot from this channel.
Glad to read this!
And then there's EOSID..aka Turn. Good explanation, Commodore!
Thanks for watching!
Captain many thanks for a good explanation.Now it’s clear👌
That's great!! You are very welcome!
Excelent video! perfect explanation! You really helped me understand it now.
I'm glad to read that it helped you!!y pleasure
Superb explanation for a Canadian Ft/nm guy lol. Thank you
You are very welcome!! Glad you like it
Nicely explain thanks trying to configute wiht Hercs
Many thanks for watching! I wish you a great day!
Hi captain. You have really good videos , and i have learned a lot from you.
About this topic , sid and app charts . The climb gradients that they show on them are calculated by Taking in consideration when there is a engine failure so we can complete that mínimum film gradients ....::.:?.
And when you refer to calcúlate the climb gradient so there is a special performance chart to do that for a B737 ..
I hope you response soon. Thank you very much
Hey, many thanks for watching and the comment!! I'm very happy the videos are helping you! The SIDs climb gradient doesn't take into account the engine failure case, that's why in case of an engine failure during take-off we perform a one engine out dedicated route.
There are tables that depending on the weight of your aircraft and the weather will provide you with the climb gradient you can achieve.
On top of that the aircraft FMC/FMS will constantly monitor if your climb performances are good enough to meet the requirements.
I wish you a great day!!
It seems like you're filling some gaps with your videos. Keep it up!
thank you very informative .Based on what pilots select the autobrakes and how the determine which deceleration rate will be used?....thank you
You are welcome! Thanks for watching! Yes that is correct!
Excellent Video. Thanks
Many thanks for watching and the comment!! I wish you a great day!!
Thank you Captain
You are very welcome!
Very good explanation! 🤝👏👏👏

Nice video! Any chance to show those performance figures on the OPT? Grazzie!
Hey, I'm glad you liked the video!! Why don't you check this SIM video that I made where I talk about take-off performances.
Video link: ua-cam.com/video/eGt0rw7rm7k/v-deo.html
Let me know what do you think 👍
@@PILOTCLIMB yeah that’s a nice video, although de PMDG OPT it’s very limited, it doesn’t even allow you to run TO-B performance, I was referring to the actual OPT you guys use in your company to see if that app would give you the climb gradients, maybe another video! Ciao!
Thank you Captain, Thank you For the knowledge ❤
You are very welcome!!!
Hello captain, I have a question.
For that missed approach climb gradient, where can I find the exact percentage of aircraft performance? FPPM? Or AFM? I can not find any of climb rate. And the MACG is based on One engine performance, is that right? Thanks.
Usually on the AFM performance you can find the tables regarding the missed approach climb gradient..
Wow! Really loved your explanation.
But you speak a bit fast...
Can you make a video for calculating Climb Gradient when there is no SID at the Airport.
For Example: KORD
Hey, many thanks for watching!!! I'm glad the video helped you, let me ask you why would you like to know your climb gradient during your departure? have a great day!
@@PILOTCLIMB @PILOTCLIMB Hi, Thank you for taking the time to reply.
I am actually practising flying on the simulator and found out that KORD does not have a SID, and I cannot fly IFR because there is not ATC in the Simulator, and in the case of VFR the scenery is too bad. I am open to any other methods for how to effectively climb and reach cruise in my situation.
Perfect 👍 thanks boss....
You are more than welcome!! Glad you liked it
Great video , thanks.

Hi Captain, you said that the standart MACG is 2.5%, if we have an one engine inoperative the MACG percentage will be higher than 2.5% cuz aircraft performance decreased am I right?
Hey Captain Im an ATPL Student love your videos , what if you have to perform a GO AROUND after touch down and you obviously have descended below your DA but you dont have the required performance for the missed approach climb. what do you do in that case ?
You still follow the missed approach as it is the best option, that will provide the best separation from the obstacles.
perfect explanation!
Many thanks for the kind comment Fabio 🙏
Let’s say missed approach gradient is more than 2.5% at your destination, Performance calculation tells you, that required landing weight
Hey, thanks for watching!! Your Landing weight should low enough to meet the Missed Approach climb gradient requirement..
Could You explain in same way climb path and connections between them, how to recalculate from ROD to Descent Gradient and to Descent path ?
Hey, many thanks for watching!! I will take your request into consideration for future videos!! I wish you a great day!
As always very simple, clear, understandable. Thank you Sir!
I'm wondering if you have in mind to create videos regarding performance calculation and all key points pilot needs to know and understand about it?
Also, it'd be useful to know what pilot must know by heart regarding Air Law, Ops.. well in all aviation subjects!
i mean something is ultimately important , something is on 2nd level etc...
I'm glad you like the videos !! Check this out: ua-cam.com/video/eGt0rw7rm7k/v-deo.html
@@PILOTCLIMB many many thanks! :)
Is it 2 eng operating or 1 en inop? Big difference what gradient you can make.
Does the required climb gradient on the SID consider All Engines Operating for the climb gradient or is it for One Engine Inoperable?
Example, a 5% required climb gradient is easy with AEO but often a challenge with OEI.
All engine, in case of engine failure you should follow the engine out route
Hello captain, hope you are doing well. I have one question. How do I know exactly that my airplane is capable to maintain this given gradient on SID, please could you give an example on B737, how can I check performance capabilities (maybe have some special tables, manual, etc. idk)
Thank you!
I'm doing great thanks!! I hope you are the same!! There tables that show you the achievable climb gradient depending on the weather and aircraft weight, on top the FMC will alert you if you will be unable to reach the target altitude
@@PILOTCLIMB Thank you Captain, for very informative videos and answers!
Thank you very much sir.
You are welcome!! Thanks for watching!
Please the table of ratio of climbing and slope % walking
To what altitude do you need to maintain the GA climb gradient?
The missed approach altitude
Thank you! As i thought. I tried to find a reference on ICAO 8168 but could not find it. If you have something I would love to see it. Thanks for answering
Thanks very much ❤❤❤👍👍👍👍
Hey, Thanks for watching!! You are more than welcome! Don't hesitate to ask questions !!👍
Hi Captain. Take you for the video. Question: You fly 737/800, 2 engine on CAT I and at minimums you will perform a go around. What it will be the elevation at 10 NM? (if the climb gradient is standard 2.5%, wind calm and GW 60 Tones)
You are more than welcome!! In order to get this imformation you need your pressure altitude, temperature and the tables on the AFM. Let me know if you can find the rest of the informations. I wish you a great day!
q1013 temp 21 all standard
@@PILOTCLIMB which table of the AFM? I think, as the answer for this question is B737/800 is flying (climb abd descend) 1000ft per 3 NM so 3000ft plus the DH, because you start the Go around at DH. But I have doubts...
@@oldsportpilot142 Hello, the 2.5% climb gradient is a minimum or is a constant climb gradient throughout your missed approach?? 2.5% climb gradient means that for every 100meters horizontally you will climb 2.5meters..
@@PILOTCLIMB If I climb 2,5 m per 100m this mean: 10 NM=19 KM=19.000m/100m=190x2,5=475m=1558ft plus DH because I go around from minimums DH
Is MSA (Minimum sector Altitude) is AMSL or AGL??
AMSL.. Thanks for watching!
Thank you very much
You are very welcome!
In case of balked landing , the gradient would be the same as the minimum as a go around ? 2.5%?
Thx bro
You are very welcome! Thanks for the support
Is climb gradient procedure design gradient same ?
According to your model 737 you are with Ryan?
Hey, I hope you are doing great!

You are doing a great job fratelo.I have a lot of question be sure that i will ask.Grazie Ciaoo
Compare to mentor YT channel you are more focus on what we need practicaly on daily basis.Mentor capt is going too deep in theory (bla bla bla )story .He is ok but your videos are more practical as i said
@@CR-eb3iy hey, many thanks for you support!! It's important for me and for the pilotclimb channel!!
I'm collecting videos ideas, so if you have anything you would like me to make a video about let me know and I will take it into consideration!!
I wish you a great weekend!
Gabriele
Could you be so kind to make a video regarding performance i mean practically What is diff . between Dispatch and In Flight landing perform.Thank you
Hi Gabriel another silly question. Is there any FMC scratch pad message in order not to comply the SID restriction depending on your weight because it never happened to me and there is nothing stated in FCOM or FMC companion as far as I know?. I always leaved the airplane in minimum clean configuration and set MCT in N1 limit pagae if I m in doubt to ensure max climb gradient up to desired altitude.
Hey, I hope you are doing great!! Your question is great!! Not Silly :).. If you can't make the SID restriction the FMC should give the UNABLE NEXT ALTITUDE message. I wish you a great day!
@@PILOTCLIMB I cant remember ..thats it thanks a lot :) the older i m the stupid i m ...:) looking for next video :)
Hi what about baulked landing and GA below minima?
Hey, thanks for watching! The baulked landing is very low altitude (even after touchdown)/energy go-around. A GA below minima is a Go Around initiated below the Approach minima. Let me know if I answered your question
@@PILOTCLIMB Well captain actually what I was trying to ask is
See like we have got a min gradient to be followed in GA segment now as you mentioned in video say we have an obstacle in GA segment now in order to ensure terrain clearance classically DA becomes higher right? So that with standard GA gradient of 2.1% terrain clearance etc can be achieved.
But say like in video if we increase GA segment required gradient and lower the minima I understood that in such a scenario of GA executed at DA/MDA with published gradient will ensure terrain clearance BUT what about the terrain clearance if say GA is performed Below DA/MDA or say we are executing a baulked landing? ( Cause may be in such a case even a higher climb gradient is maintained still it can breach terrain clearance floor just because GA is now executed from well below point)
This minimum gradients are ground refered?
Yes the climb gradient percentage is based on a horizontal distance that is not an Air distance..
@@PILOTCLIMB Thanks im studiyng for atpl performance exam😂
03:15 explanation incorrect. Correct is “X feet gained to Y Nautical miles distance traveled. “
Can a normal person climb 40% without tools
you are not explaining approach climb or landing climb.
There will be a separate videos about that!! I wish you a great day!
@@PILOTCLIMB for positive rate : B737 is always approach climb limited( it is mentioned in CBT) but this wasn t purpose of this great video
@@PILOTCLIMB by the way, great video.. just not what I was looking for :)
Dude please slow your speech speed , do you have a plane to catch ? 😂
