3240 complex written Flashcards
Engine model number for the left engine
IO-360-B1G6
Engine model number for the right engine
LIO-360-B1G6
what is a complex airplane
retractable landing gear
flaps
controllable pitch propeller
what’s the difference between the left and right engine and what are the benefits
left engine = cw rotation
right engine = ccw rotation
eliminates asymmetrical thrust, left turning tendency, and a critical engine
what’s the purpose of the propeller governor
maintain constant RPM setting and controls engine speed by varying the pitch of prop to match load torque
what fluid goes in and out of the governor
engine oil
if there’s a leak in the governor system, what happens to the propeller blade
nitrogen and the spring causes blade to go into a high pitch low RPM
what hold the propeller in high and low pitch
high: nitrogen pressure, spring and counter weights
low: oil pressure
how is the landing hear actuated
hydraulic pressure is used to extend and retract, driven by an electric pump
what is the procedure if the gear doesn’t extend
pull the emergency gear
confirm that the gear switch is in the down position incase it does start to work there arent counteractions
what holds the gear in the down positions
springs assist in gear extension and in locking the gear in the down position.
once down and locked, J hooks engage, springs will maintain force on each hook to keep it locked until it is released by hydraulic pressure
what holds the gear in the down position in the event of side-loaded landing
over-center joint also keeps the gear down
what would you suspect if the gear dropped when it was already in the up position?
there is a hydraulic leak
how are you able to tell if the gear is down and locked
3 green indicator lights
what PSI is the hydraulic fluid held at when in the up position
1800PSI +/- 100PSI
What would activate the landing gear horn
MP below 14in
gear in the up position while on the ground
gear in the up position and flaps at 25 or 40 degrees
Warning below 400ft
Caution above 400ft
where is the hydraulic power pack located (landing gear hydraulic reservoir)
aft of the rear bulkhead/baggage compartment
why do you have to use the emergency gear with hydraulic failure
to relieve the hydraulic pressure
If moving the landing gear switch from the down position to the up position on the ground, what prevents it from happening
The squat switch
how long does it take the gear to extend
6 to 10 seconds
if you extend the gear but the lights don’t come on, what do you check
- mirror (nose wheel)
- circuit breaker
- dimming panel lights knob
- battery master
- alternator switches
what does the left main gear squat switch do
prevent hydraulic pump from actuating while on the ground
what does the right main gear squat switch do
starts the tach time, maintenance time and switches the heater from blower to ram air when airborne
what type of horizontal stabilizer does the Seminole have
all moveable horizontal stabilator
what is the purpose of the anti-servo tab and what does it do
provided longitudinal stability and trim. it moves in the same direction as the stabilator but with increases travel
what is the purpose of flaps
increase chord line which increases the AoA- creating more life and also more drag.
increase rate of descent without increasing airspeed
what is the flap settings for takeoff
0 to 25 degrees
what is the ground restriction for the use of pitot heat
3 minutes
what is the purpose of the scupper drains
its around the filter neck of the fuel tank. it is used to collect spillage of fuel during servicing. the fuel is drained to the ground through a drain line rather than flowing into the aircraft structure
when can you not cross feed the engines
on takeoff
shutdown of engine
can’t Xfeed at the same time
why should you check the fuel flow when you turn off the fuel pump
to ensure that the engine is still receiving fuel to operate within limits
what is the voltage of the electrical system alternator
28 volts
what is the load meter
it shows the total percentage of the load that is placed on the electrical system
what is the ammeter
it shows the positive and negative change and if the alternator is supplying enough electricity
what is the purpose of the busbar
convenient place to attach stations for electrical power distribution
what are the different buses
Hot battery bus
Essential bus
Lighting bus
Emergency bus
Non-essential bus
Avionics bus
what is on the emergency bus
PFD
Avionics, AHRS, ADC
Nav. 1
Comm 1
Audio Panel
Engine Indications
Standby instruments
where do you plug in the external power source
aft right of the aircraft
how many volts can you hook up with external power
24 to 28 volts of direct current
*you must have all electrical equipment off before applying or removing the external power
how much fuel does the heater use and from which tank
0.5GPH when turned on which gets pulled from the left engine
How do you turn the heater on
turn cabin heat switch on
slide air intake open
slide temp knob to desired temp
how do you turn the heater off
on the ground: switch cabin heat to fan for 2 min. turn off then slide air intake off
air: switch cabin heat to off, leave air intake open for 15 seconds and then slide off
what is the purpose of the unfeathering accumulator
store engine oil under pressure form the governors, which is released back to the governors for propeller unfeathering when the propeller lever is moved out of the feathering position
how long does it take to feather
10 to 17 seconds
how long does it take to unfeather
8 to 12 seconds
what is the purpose of the anti-feathering pins
to prevent the propellers from feathering on shutdown, to prevent over stress on the starter when starting
** operated by centrifugal force
what is Vyse and what is that number
best rate of climb with one engine operating
**88Kias
what is the purpose of cowl flaps
regulates cooling air for the engines
what is the proper main gear strut length
2.60in +/-0.25in
what is the proper nose gear strut length
2.70in +/-0.25in
how many times can you engage the starter if the engines does not start
6 times
starter cranking periods are limited to 10seconds with a 20second rest between each attempt.
must wait 30 min after the 6th attempt
what do you need to do when you operate alternate static source
storm window and vents must be closed, heater and defroster must be on
you are using cabin pressure instead of outside pressure. the altimeter error should be less than 50 ft
below what RPM will the props not feather and why
below 950 RPM due to the anti feathering pins will lock (engage)
at what fuel quantity will indicate a CAS warming and caution
