Hi, nice presentation as usual, just one thing referring to your comment about the le flaps extending down - when deployed they primarily change the overall shape of the leading edge increasing both the camber and partially the size of the airfoil and thus producing more lift - while the primary purpose of the slats when in the extended position as they droop down they primarily increase the camber and thus the lift while when they go to the fully extended position and they move forward they allow air pressure air from underneath the wing to flow to the top side energizing the boundary layer and this delaying the onset of the stall.
And the system B electric pump doesn’t pump enough to operate the auto-slats, right? So, that’s why you need the PTU? To use the A system to increase system B pressure and flow?
In 737,the elevator trim is controlled by the Jackscrew in Horizontal stabilizer.What components are controlling rudder and aileron trim ,Like The Jackscrew for elevators.
Very well explained thank you
Juan, you are the best, hands down! Norway, out.
Thanks. This is helpful.
Thank you Bro!
WELL DONE MAN

more like this with sketch examples like you just did.
even though i checked all working conditions of PTU&LGTU through FCOM, i still have 2 questions in mind and any answer is well appreciated 🙏
So basically PTU can extend and retract slats and LE flaps at a loss of B system pressure?
Terrible briefing. You should also explain to the student all the conditions required for the PTU to operate 🤪
