Flashcards in Primary Flight Controls Deck (12):
Primary flight controls are all comprised of ___ and ____
Control surface and control tab
The rudder hydraulic pressure decreases to zero when ____________.
The RUDDER POWER switch is turned off
The primary purpose of the EFAS is to counter ___________created by ________engine asymmetric thrust during ____________ and ____________.
Adverse yaw; outboard; takeoffs and landings
The engine failure assist system (EFAS) provides ______________ rudder input based on N1 RPM differential between the outboard engines.
Which flight control surface is mechanically locked out of the control system when the outboard flaps are fully retracted?
Which primary flight control surface is normally moved hydraulically?
A rudder feel unit and Q-bellows provide rudder feel at the pedals during hydraulic powered operation. The amount of feel at the pedal is a function of, and proportional to, the amount of _____ and __
Pedal deflection and airplane speed
Before checking the powered rudder during preflight, allow hydraulic rudder pressure to build to approx. ________ psi.
To make the pilot aware of a N1 differential of 1,500 rpm (30% N1) or greater between outboard engines, which indicates a probable engine failure, a ___________ light is installed on the pilot’s forward panel.
ASM THRUST light
What are the primary flight controls?
Rudder, elevator and ailerons
What should you do with the flight controls if winds are expected to gust up to 50 knots on the ground?
Retract the flaps
