16
Q

How long does it take for the gear to be retracted or extended?

A

6-7 seconds.

17
Q

Why is there a thermal relief valve?

A

Protects it from temperature and pressure changes (3000 psi) by releasing excess pressure as the airplane climbs or descends.

18
Q

Alternators?

A

Two 14 volt 70 ampere.

19
Q

Battery?

A

12 volt 35 ampere-hour

20
Q

Overheat switch?

A

Approx 450 degrees (+/- 80)

21
Q

Where does the combustion heater take fuel from and how much?

A

Left fuel selector, 1/2 gal/hr.

22
Q

What are the limitations of the AP?

A
  • 185 kts max
  • 80 kts min
  • no more 25 degrees flaps
  • prohibited TO/LND
  • missed appch and go around
  • CAT I only
  • no SE appch
  • 200 ft below
  • manual must be on board
23
Q

What type of engine Seminole has?

A 
2 engines: 180 HP 2700 RPM
O-360-A1H6 (LO- right)
4 cylinder 
Direct drive 
Full feathered
Air cooled
Horizontally opposed
Carbureted
24
Q

What type of oil?

A

MIL-L-22851 Ashless Dispersant

25
Q

What type of prop?

A 
2 blade hartzell 
Constant speed
Hydraulically actuated
Full feathering 
72-74"
26
Q

Low pitch, high rpm?

A

Oil and aerodynamic twisting force

27
Q

Unfeathering time?

A

8-12 seconds

27
Q

Why is the landing gear retraction speed slower then the extension speed?

A

Because the nose wheel will unlock and ram air will push the nose wheel back into the wheel well.

28
Q

What does the left squat switch do?

A

Prevents accidental gear retraction on the ground.

29
Q

What does the right squat switch do?

A

Activates the stall warning.

Starts the MX Hobbs time.

30
Q

What does the up-limit switch on the nose gear do?

A

Turns off the heater blower.

31
Q

Brakes systems?

A

Two single-disc, double-puck brake assemblies.

32
Q

Electrical system?

A

Negative-ground, dual-fed, split-bus system.

33
Q

What does the ACU (alternator control unit) do?

A

It uses a voltage regulator and a overvoltage relay.

Regulators- maintain 14 volts between the two (load sharing).

Relay- will take the alternator offline if exceeds 17 volts.

34
Q

Six bus bars which distribute electricity?

A
  • Battery bus (clock, flight times)
  • Avionics bus #1 (comm nav 1, xponder, pitch trim)
  • Tie bus
  • Main bus (lights, pumps, starter, pitot heat)
  • Avionics bus #2 (comm nav 2)
  • Non-essential bus (cabin heater, vent, blower)
