special fluids. - Answers True
TUC at FL350 is estimated to be - Answers 30 sec to 60 sec
Cabin pressure is controlled by modulating the exhaust of the cabin air via - Answers Outflow valves
Dump valves allow pilots to manually vent the cabin pressurization - Answers true
Above FL350, ____________regulators continually supply 100% O2 under positive pressure in the
event of lost cabin pressure. - Answers Diluter demand
If an aircraft has a significantly larger MTOW then MLW, they will be designed to incorporate
_________ so they can jettison fuel if needed in an emergency. - Answers Fuel dump valve
A ___________ is simply a separated segment of a larger fuel tank. - Answers collector bay
__________ refers to the small venturi-type ports which are used to draw fuel into the collection
lines. - Answers Motive flow
The electric standby boost pump functions as a backup pump for the high pressure engine driven fuel
pump and can keep the engine running if the high pressure engine driven fuel pump fails. - Answers
False
What is motive flow in reference to the fuel system? - Answers small venturi-type ports, used to draw
feul into collection lines
With smoke in the cockpit, the pilot dons their oxygen mask and selects "emergence." What type of
oxygen delivery system are they selecting? - Answers Pressure demand
Which of the following is a function of the electric standby boost pump? - Answers It is used in
crossfeed operations
When the max amount of oil is in the hub or the propeller, the blades will be at a ______ angle
(pitch). - Answers negative
The sir in the P3 line is used to run such equipment as ____________ in a typical KingAir during
normal operations. - Answers pressurization, heating, wing deice boots
Speed brakes are designed to - Answers increase drag rather than to spoil lift
The peak ratio of cabin pressure to outside air pressure in a pressure vessel is called the maximum
differential. - Answers True
In a fuel system, jet pumps use __________ power to move fuel. - Answers motive flow
What are some of the functions of a squat switch or weight on wheels (WoW) switch? - Answers
deploy the spoilers, change the prop pitch to beta, depressurize the cabin, disable gear retraction
A failure of the bleed air system is usually an EMERGENCY and is taken care of with EMERGENCY
MEMORY ITEMS that require action before a checklist is referred to. - Answers True
Unless there is an emergency, the maximum operating altitude of the CABIN while operating as a Part
135 or 121 operation is - Answers 10,000ft
What does FADEC stand for in regards to aviation? - Answers Full-Authority Digital Engine Controls
What components make up the "PACK" in terms of the environmental system? - Answers AMC, bleed
heat source, VCM, and mixing valves
Using the reference waterwheel system as described in your textbook, the RESERVOIR best
corresponds to what part of the hydraulic system? - Answers the accumulator
What are capacitance fuel quantity indicators? - Answers All of the above (used to measure fuel
mass, measure electrical capacitance across the metallic probes, generally is accurate within 3% of
actual fuel in tanks)
