3800
what is the skin of the fuselage attatched to
bulkhead stringers and formers
storm window max speed
129
how do controls work
uses a system of pulleys and cables
what parts does the empannage consist of
tail, rudder, vertical stabilizer
what does the anri-servo trim tab do
moves in the same direction as the control surface
how far does the trim tab travel on the stabilator
4 degrees up
9 degrees down
benefit of a t-tail configuration?
avoid the disturbed airlfow
risk of a t-tail
deep stalls
what does the elevator down spring do?
prevents entering a deep stall.
when tension on the spring is greater than airlfow it forces the nose down
what kind of ailerons does the semi have and how far do they travel?
differential-frise
23 degree up
17 down
what kind of fuel system does the semi have
positive pressure fuel feed
what fuel systems does the semi have
engine driven and auxiliary
what does the scupper drain do
allows for overfill around the fuel cap to escape
what does the fuel vent do and how many are there
ant-ice and 2
how many fuel pumps do we have
4
what does the fuel flow transducer do?
provides information to the GDU
what does a flow divider do
disperses the fuel into the cylinders
what does a fuel servo regulator do
controls the air/fuel ration
three way to cool an engine?
air,fuel,oil
what is a probe and what does it do
acts as a manifold pressure sensor located inboard on rear cyclinder
what does a winterization plate do
installed below 50f and limits how cold an engine can get
what does a low temp bypass valve do
prevents oil from passing through the cooler when the engine is cool
what is the purpose of a baffle
directs airflow to the back of the enigne
negative affects of a hot engine
impairs lubrication and weakens parts
how to control temperature?
cowl flaps, fuel, airspeed, power, mixture
main difference between turbo and super charged engines?
high altitude flying
what happens to normal aspirated engine when altitude is increased?
power decreases
what does a turbo/super charged engine do
forces more air into the engine
what is an altitude engine
a reciprocating engine witha rated power for high altitudes
what is a critical altitude?
highest altitude a turbocharged i=engine can produce its rated horsepower
what is a turbo charger?
compresses air before it mixes with the fuel by a turbine and compressore
what is a super chargers
compresses using a belt
what engine do we have?
lycoming-IO-36-BIG6
when can carb ice form?
can form up to 70f if humidity is high enough
what role do the magnetos play with the ignition system?
generates energy for the spark pligs to ignite fuel
how many spark plugs does the semi have
16 for engine 1 for heater
t/f ignition is dependent on electrical system
f
what does it mean if there is no rpm drop on run up
failed mag
what does a propeller convert?
torque into thrust
what prop does the semi have?
hartzell, counter rotating, constant speed, fully feathering
what is the out of governing range?
blue lever can only vontrol rpm when it is above 1500
what is manifold pressure?
absolute pressure of fuel-air mixture indicating the power being generated
what does the governor do?
changes the prop pitch
what does the oil pressure get boosted to with the governor?
275 psi
what happens with a high pitch low rpm?
counter weights, spring force, and nitrogen charge
what happens with low pitch high rpm?
aerdynamic twisting, oil pressure
how to use primer on a carb engine?
electrical boost pump on
fuel selector for corresponding tank on
what does feathering do and how long does it take?
gives us better performance
take 6 seconds (10-17 with accumulator)
what do antifeathering pins do?
prevents feathering during shutdown and below 950 rpm
what does an unfeathering accumulator do?
oil stored under high pressure by a nitrogren charge of 90-100 psi
(8-12 seconds to unfeather)
what does a synchronizer do?
matches rpms between engines
what does a syncrophaser do?
matches RPM and off-sets the prop passge over the fuselage
how many volts and amps for the alternator?
