- In today's video, you are going to learn what is the Best Turbulence Penetration speed, we are going to use the Boeing 737 X-plane 11 Simulator to do a practical Example.
Depending on your Cost Index the FMC of the Boeing 737 will calculate a Climb, cruise and, descent speeds. If the air is smooth you can simply follow the FMC speeds.
The situation changes when you are flying into some turbulence, in this case, there is something called BEST TURBULENCE PENETRATION Speed.
This is a speed that you should set when facing turbulence, the Boeing 737 this speed is 280Kt or 0.76MN whichever is lower.
In the video, you will see how to set this speed, and how to change it from 280Kt to 0.76Mn

👇Comment below with your questions and thoughts👇
Hi Captain, I've watched this video and as usual, I've learnt something new and very useful. I have my usual questions for this video regarding turbulence :
1) When you fly in these conditions, I think I read somewhere that some companies suggest to revert to CWS instead of using the A/P. Do you use this rule as well?
2) When you went through clouds the humidity was very high and the OAT was below 10 C. Shouldn't you have selected the TAI? (Engines and/or Wings Anti-Ice)
3)Always in regard to turbulence, isn't better to put the Engine Start Switches on the FLT position?
Thanks for the video Captain and thanks for your answers as well. Have a great day ☺
The procedure regarding the use of CWS is correct, however the crew should use sound judgment in order to decide whether to leave the CMD or use the CWS. Regarding the anti-ice you are correct, however, you need to take into account the SAT, if that is -40 or below you don't have to use anti-ice. Be careful when using wing anti-ice at high altitudes, you might have pressurization problems. You should position the Start switches to FLT if you are flying into severe turbulence.
@@PILOTCLIMB Yeah it once happened to me during a cruise at FL370. I had wing anti-ice on and the BLEED TRIP OFF light illuminated ( I guess it was from the left engine) and pressurization problems as well. Thanks for the answers. OAT and SAT refer to the same thing if I recall correctly. TAT is the total air temperature, which considers the Outside Air Temperature + the Compressed Air the comes into the Probe and tends to make the temperature higher.
Thx Cap
You are very welcome
Hello, ok for climb and descent…what about during cruise? Thanks
The same applies..
Good Day Capt Gabriele,
1. How many ton or kg of jet fuel burn on B737 at cruise flight level for example FL 330?
2. How many ton or kg of fuel used when B737 fly below 5000 feet during approach?
3. How many ton or kg of fuel used for taxing from gate up to runway for takeoff on B737?
Have a nice weekend... And thanks for this video... 👍👍👍
Hey, I hope you are doing great!! The fuel flow of a Boeing 737 that is on the air is approximately 2400kg/h, this works well for all situations. However, this might change depending on the Aircraft age, configuration, and Weather. The taxi fuel changes a lot depending on the airport, some have a very short taxi, some have veeeery long taxi (MAD).
@@PILOTCLIMB Thanks Capt Gabriele, 2400 kg/hour is for 2 engine right?
Hello captain i would like to ask you about something not related to this topic , when i lower the flaps does it increase or decrease the angle of attack
Hey, great question, if keep the Aircraft attitude constant the AOA will increase when you extend the flaps.
@@PILOTCLIMB thank you captain for your effort , but i read a topic that if you lower your flaps the AOA wil increase momently then with flaps you can fly at lower AOA than wit flaps up
Good Morning Capt., which 737 do u prefer? PMDG 737 or ZIBO MOD? which one is more Realistic?.thank you. capt. good day.happy landings.
Good morning, Well I like them both a lot! The ZIBO is great and It is super easy to install and keep it updated. The Pmdg is a software that is extremely stable. If you want to keep it simply but still high levels I would go to the ZIBO. If you are looking for well tested and stable software than go with the PMDG.
@@PILOTCLIMB thank you capt.
Hi, great video! 👍 I have a question for you. In my study guide, I am told to study the engine instruments for GA aircraft. Please give me a list of them, I just want want to make sure I have covered them all. Thank you
Hey, Thanks for watching!You can google Aircraft Engine Instruments and you will get a list. I wish you a great day
@@PILOTCLIMB will do thanks 👍
Good day, Gabriele. Thanks for the your video! I have a question. For example: we’re flying below 10.000feet and speed should be 250kts. but we have a turbulence. Do we need increase our speed to 280kts? After confirm from ATC no speed restrictions. But in this case we’ll reduce AOA and only after speed 280 continue climb.
Hey, thanks for watching!!! You should try to keep 250 however, if the situation is bad you inform ATC and set the best penetration turbulence speed.. safety come first..
@@PILOTCLIMB Hi, Captain! Thanks for your answer! Roger!
