Where are the breaks located on almost all aircraft?
The main landing gear.
Where does an aircraft get its air pressure for pneumatic systems
Bleed air from the compressor section or apu.
Name the five stress factors on an aircraft.
Tension, Compression, Torsion, Shear, Bending
Name some hazards of a hydraulic leak.
Fire, corrosion, electrical system damage, injury or death to person or persons, loss of control, etc.
Name some secondary control surfaces.
Flaps, trim, slats, spoilers, air-breaks, etc.
What two colors are used for landing gear position lights?
Green for down and locked, amber for not locked nor down.
Name some things that use pneumatic pressure.
AC, cabin pressure, landing gear systems, anti-icing systems.
Name the 6 benefits of winglets.
Fuel efficient, better climb, noise reduction, extended range, aesthetic considerations, environmental impact reduced
What color is hydraulic fluid typically?
Red or yellow
Name the types of methods used to control flight surfaces.
Manual, hydraulic, fly by wire, fly by light
What type of break system is most often used for general aviation?
Hydraulic caliper breaks.
What type of system mirrors how pneumatic systems work?
Hydraulic systems.
Name the 8 types of winglets.

Where is the hydraulic shutoff valve typically found?
At the firewall.
What is the main component allows for fly by wire/fly by light systems to operate effectively?
A computer.
How are most breaks operated in aircraft.
Toe breaks on the rudders with some aircraft using heel breaks.
What is the "heart" of pneumatic systems in most GA aircraft?
The vacuum pump.
What do vortex generators do?
Create mini wingtip vortices to energize the boundary layer.
What pressure range do most aircraft hydraulic systems operate at?
3,000-5,000 psi
What is it called when engine exaust direction is used to steer the aircraft.
Thrust vectoring.
Name the two most common types of landing gear configurations.
Tail-wheel and nose wheel.
What would flight condition would make the loss of a vacuum pump extremely dangerous?
Flying in IMC conditions.
