What are syptom differs from hypoxia and hyperventilation - Answers limbs and fingernails turn
blue
What is adverse yaw? - Answers The tendency of an airplane to yaw opposite the direction it is
rolling.
What are the oxygen requirements for a pressurized cabin above FL250 - Answers 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 - Answers 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 - Answers main- 2.6 inches +/- .25
inches
nose- 2.7 inches +/- .25 inches
If the pilots brakes fail would the co pilots brakes still work - Answers Yes because they have
separate cylinders
How does a turbocharger work? - Answers 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 - Answers 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 - Answers 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? - Answers Nose compartment
What is a MEL - Answers A minimum equipment list (MEL) is a list which provides for the

Why do we use mineral oil for the first 50 hours - Answers to break in the engine parts and
because it is less viscous
Define brake horsepower. - Answers The power delivered by the crankshaft
What is Thrust? - Answers 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.
What is preignition? - Answers Preignition occurs when the fuel/air mixture ignites prior tot he
engine's normal ignition event. Premature burning is usually caused by a residential hot spot in
the combustion chamber, often created by a small carbon deposit on the spark plug, a cracked
spark plug insulator, or other damage in the cylinder that causes a part to heat sufficiently to
ignite the fuel/air charge
What is denotation? - Answers Detonation, is an explosion of the fuel-air mixture inside the
