Climb Gradient Explained - [All you need to know about your minimum rate of climb].

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!!!

[@lexydeny4669]

Great Video, want to ask if this climb gradients are designed with all engines operating?

[@PILOTCLIMB]

@@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! Gabriele

[@XXODD1982]

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

[@jairoramirez1077]

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

[@PILOTCLIMB]

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!!

In case of balked landing , the gradient would be the same as the minimum as a go around ? 2.5%?

[@aritoni9363]

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 ?

[@PILOTCLIMB]

You still follow the missed approach as it is the best option, that will provide the best separation from the obstacles.

[@ihorkohut7290]

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?

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.

[@PILOTCLIMB]

Usually on the AFM performance you can find the tables regarding the missed approach climb gradient..

[@alexseal300]

Let’s say missed approach gradient is more than 2.5% at your destination, Performance calculation tells you, that required landing weight

[@PILOTCLIMB]

Hey, thanks for watching!! Your Landing weight should low enough to meet the Missed Approach climb gradient requirement..

[@daviddinan4110]

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.

[@PILOTCLIMB]

All engine, in case of engine failure you should follow the engine out route

[@muborak9195]

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!

[@PILOTCLIMB]

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

[@muborak9195]

@@PILOTCLIMB Thank you Captain, for very informative videos and answers!

[@samuelcv6565]

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.

[@PILOTCLIMB]

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!

I am open to any other methods for how to effectively climb and reach cruise in my situation.

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)

@@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...

[@PILOTCLIMB]

@@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..

Hi what about baulked landing and GA below minima?

[@PILOTCLIMB]

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

[@ad_akp1662]

@@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)
