- anytime 25 degrees or more of flaps are extended and all 3 gear are not down and locked

Red heater over temp annunciator light on the instrument panel will illuminate
What is the primary indication the heater is overheating and what can be done to remedy the situation?
Cold air coming in the cabin; nothing can be done until the aircraft is on the ground. The reset button is on the heater unit itself in the nose compartment.

Blockage of the air intake valve due to snow, ice, or other foreign obstruction

100 RPM drop is normal, 175 RPM drop apiece is allowed with a differential of 50 RPM
What should be done if the cylinder head temperature becomes too hot? (greater than 500 F)
Reduce power, open cowl flaps, and enrichen the mixture, lower nose if climbing
What holds the gear up in the retracted position?
Hydraulic pressure
What happens if the hydraulic system malfunctions or leaks?
The gear extends slowly
Why are the prop controls pushed forward before landing?
To provide maximum power simply by adding full throttle in the event of a go-around
What are the 12 factors that affect Vmc?
critical engine inoperative, inop engine windmilling, up to 5 degrees bank toward op engine, landing gear retracted, aft CG, max gross weight, max power on op engine, sea level, flaps TO position, cowl flaps TO position, trimmed for TO, ground effect negligible
What is VMCA?
The minimum flight speed at which the airplane is directionally controllable with one engine inoperative
What does basic empty weight include?
Optional equipment, full oil and unusable fuel, hydraulic and brake fluid
What happens to the CG as fuel is burned or the gear retracted?
The CG is not significantly affected
How many fuel tanks does the Seminole have and where are they located?
2 tanks. 1 behind each engine (in the nacelle)
What is the fuel capacity of each tank?
55 gallons total, 54 gallons usable
How many fuel pumps total are there?
70 & 71: 6 total- 2 engine driven, 4 electric (2 for heater)
72 & 73: 5 total- 2 engine driven, 3 electric (1 for heater)
What is the purpose of carburetor heat?
Carb heat provides heated air to the carburetor in the event of icing and also serves as the alternate source of engine air
What is the temperature range where carb ice is most likely to occur?
-7 C to 21 C; also when relative humidity is high
How many cowl flap settings are there?
3 - full open, full closed, intermediate
What is the advantage of counter-rotating props?
This eliminates the “critical engine” and lowers VMCA
What is the critical engine?
The engine whose failure most adversely affects the aircraft, i.e. the one with the shortest moment arm thus requiring less resisting force to maintain directional control
What controls the pitch of the prop?
Oil pressure supplied by the governor and nitrogen from the propeller dome. Oil pressure sends the propeller toward the high rpm or unfeather position, nitrogen and a large spring send the prop toward the low rpm or feather position and prevents over speeding
What is the precharge pressure of the unfeathering accumulator?
70-75 PSI (depending on temperature)
How long does it take for the prop to feather?
10-17 seconds
What is the PSI in the prop governor?
200-300 PSI
What kind of gear system is installed in the Seminole?
electrically controlled/activated, hydraulically actuated
How long does gear take to cycle?
6-7 seconds
How is the gear held in the extended position?
Down locks hooks, springs maintain force on each hook
What happens when the emergency gear extension is used?
Hydraulic pressure is released and the gear freefalls
Where is the gear pump and reservoir located?
In the tail section
Where is the squat switch?
Left main gear
Is the hydraulic reservoir for the brakes the same as for the gear?
No, the brake reservoir is in the nose compartment
What are the possible flap settings on the Seminole?
0, 10, 25, 40
How are the flaps actuated?
Manually
What are the limitations on crossfeed?
Level flight only and only one engine
What is the electrical system on the Seminole?
70 & 71: batt- 35 amp-hr, 12 V; 2 belt-driven alts- 70 amp, 14 V
72 & 73: 2 batts- 13.6 amp-hr, 24 V; 2 alts- 65 amp, 28 V
What happens if the alternator voltage becomes too high?
The overvoltage relay trips the alternator off automatically and the alternator overvoltage light illuminates
(72 & 73: 32 V voltage regulator will kick off alternator)
What should be done if the alternator overvoltage light illuminates?
Check circuit breakers, turn the alternator switch off and then back on to reset the alternator, reduce the electrical load and monitor the ammeter
Where is the external power plug located and what is it’s purpose?
Under the nose on the right side; allows current to flow from an external power source to the starter contactors
Where is the actuator for the alternate static source?
Left side wall
How is the static system drained?
By pushing the 2 pitot/static drain buttons on the left side wall by the left pilot seat

When the gear retracts
Where is the fuel drawn for the heater?

increases
