Seminole HK Flashcards
Drift Down
unavoidable loss of altitude you will experience if you lose an engine above the single engine absolute ceiling (no longer maintaining 50fpm), fly Vyse to minimize descent
Vsse is designed by?
manufcator @ 82
definition: min speed practicing single engine for training purpose
Max/min oil pressure
25-115PSI
Oil loss in one engine
secure engine immediately including shutdown and feathering prop to reduce parasite drag
V speed at red line lower end
Vmc 56
Which speeds not on ASI
Va
electrical system
Battery
each engine 14V, 70amp alternator
battery 12V, 35amp at nose of AC
Fuel
100LL or 100
total 110 gals
108 useable
what indication when gears are down and locked
3 greens
shuttle valve purpose
regulate flow of hydraulic fluid
Door opened during take off, what should you do
OEI performance
reduced by 80-90%
Manual flight controls
by pulley and wires
Define & speed
Vle
Vxse
Vle - max landing gear extended speed 140
Vxse - best angle of climb speed 82
Flaps type
slotted
Aierones type
differential frize, helps with adverse yaw
Stabilator
anti servo tab, prevent overcontolling by providing resistance to pilot
Alternator over voltage relay purpose
over voltage relay detects when the current voltage exceeds a present value
->will disconnect alternator when voltage is greater than 17V
- pilot will see ALT light illuminated and can turn it off for 1 sec to resset
operative alternator output should not exceed 60amps
Annouciator panel - low bus illuminate meaning
bus voltage (14V) drops to 12V or below
could be alternator not working
landing gear
fully retractable tricycl, hydraulically actuated behind baggage compartment
how pilot maintain engine settings in PA44
governor control the propeller pitch
what is the feathering lock
prevent feathering below 950RPM
how many vents in the fuel system
6
if one engine fails and experience a oss of directional control, what do you do?
reduce thrust of the operating engine
why is the heater not installed near exhaust manifold
because the engines are located on the wing
heater fuel burn
1/2 gallon/hour, set fuel from the left
- heater will function with left fuel
