What part of your eyes do you use mostly during the day - CORRECT ANSWER-
cones
What part of your eyes do you use at night - CORRECT ANSWER-rods
Why at night might you have trouble seeing something directly in front of you -
CORRECT ANSWER-rods use peripheral vison
What is motion sickness and how do you help it - CORRECT ANSWER-Motion
sickness is when the brain is receiving contradictory signals from its senses.
When your vestibular and visual senses are not receiving the same signals. Some
solutions are: cold air, not moving head, or look outside
What are syptom differs from hypoxia and hyperventilation - CORRECT ANSWER-
limbs and fingernails turn blue
What is adverse yaw? - CORRECT ANSWER-The tendency of an airplane to yaw
opposite the direction it is rolling.
What are the oxygen requirements for a pressurized cabin above FL250 -
CORRECT ANSWER-Above FL 250, each passenger must have an additional
10min supply of Oxygen.
Above FL 350 one pilot must use an oxygen mask unless, the aircraft is below FL
410 and there are two Pilots at the controls.
If Above FL 350 and one Pilots needs to exit the cockpit then the other must use
an oxygen mask.
What is a bellcrank - CORRECT ANSWER-A double lever in an aircraft control
system used to change the direction of motion.
how high should the main gear and nose gear struts be - CORRECT ANSWER-
main- 2.6 inches +/- .25 inches
nose- 2.7 inches +/- .25 inches

If the pilots brakes fail would the co pilots brakes still work - CORRECT ANSWER-
Yes because they have separate cylinders
How does a turbocharger work? - CORRECT ANSWER-A turbocharger recovers
waste energy from the engine exhaust stream and uses it to power a turbine
which in turn drives a compressor. This compressor draws in ambient air,
compresses it and then feeds it into the engine intake resulting in a greater mass
of air and, proportionally, a greater amount of fuel entering the cylinders on the
intake stroke. This increase in air and fuel results in the turbocharged engine
being more powerful and efficient than its naturally aspirated counterpart.
What does a camshaft do - CORRECT ANSWER-opens and closes cylinders'
intake and exhaust valves. It also runs the accessory gear drive which is
connected at the end of the Cam shaft and runs the magnetos, the engine driven
fuel pumps, and the oil pump for the engine. These are all connected to the
accessory gear drive by small gears)
You are in a climb how does the prop maintain a constant rpm - CORRECT
ANSWER-You would be in a under speed condition so it would make the fly
weights fall inward to allow more oil into the prop and allow the prop to go back
to the Pre set RPM
- Fly weights fall out = oil out of hub
- Fly weights fall in = oil in to hub
Where is the main battery located? - CORRECT ANSWER-Nose compartment
What is a MEL - CORRECT ANSWER-A minimum equipment list (MEL) is a list
which provides for the operation of aircraft, subject to specified conditions, with
particular equipment inoperative prepared by an operator in conformity with, or
more restrictive than, the MMEL established for the aircraft type.
Give 2 disadvantages of carburetors - CORRECT ANSWER-1) carb ice
2) harder to start in cold
3) can't provide even fuel air mixture all the time
Why do we use mineral oil for the first 50 hours - CORRECT ANSWER-to break in
the engine parts and because it is less viscous
Define brake horsepower. - CORRECT ANSWER-The power delivered by the
crankshaft
What is Thrust? - CORRECT ANSWER-The force that drives the plane forward
(opposes drag) and it created by the relative wind coming in contact with the
propeller (Burnueli's principle). The prop is a wing that is turned 90° into the
relative wind.
