Q

Encountered icing…

Q

Landing with flat main…

A
  1. appraoch - normal
  2. wing flaps - 30
  3. touchdown - good tire first and hold as long as possible with aileron

Q

Landing with flat nose tire

A
  1. approach - normal
  2. flaps - as required
  3. touchdown - on mains hold nose as long as possible
  4. when nose wheel touches, maintain full up elevator
17
Q

Ammeter shows excessive rate of charge

A
  1. alternator - off
  2. nonessential electrical equipment - off
  3. flight - terminate asap
18
Q

Low voltage annunciator

A
  1. avionics master switch - off
  2. alternator circuit breaker - check in
  3. master switch - off
  4. master switch - on
  5. low-voltage annunciator - check off
  6. Avionics master switch - on

if low voltage illuminates again

  1. Altnerator - off
  2. Nonessential radio and electrics - off
  3. Flight - terminate asap
19
Q

Landing without elevator control…

A

Trim for horizontal flight at 65 KIAS and flaps set to 20

do not change elevator trim, only use throttle to adjust glide angle

Trim full up for flare and power adjusted so airplane will rotate to horizontal attitude for touchdown.

20
Q

An inadvertent spin has occured… Recover!

A
  1. Throttle - IDLE
  2. Ailerons - Neutral
  3. Rudder - Apply and Hold full opposite rudder
  4. After rudder reaches stop, move control wheel briskly forward far enough to break stall
  5. Hold these controls until rotation stops
  6. As rotation stops, neutralize rudder and make a smooth recovery from resulting dive
21
Q

Some engine roughness indicates spark plug fouling. What do you do?

A

Verify by turning ignition switch from both to either L or R position

If there is obvious power loss in single ignition, there’s a good chance it’s fouled.

Lean the mixture to recommended lean setting, if that doesn’t clear it in several minutes proceed to the nearest airport for repair using BOTH position unless extreme roughness indicates only using one.

22
Q

Engine-driven fuel pump fails, what do you do?

A

Switch to the auxiliary fuel pump and terminate flight ASAP

23
Q

You notice a total loss in oil pressure accompanied by a rise in oil temperature… First reaction?

A

Engine failure is imminent

Reduce engine power immediately and select a suitable forced landing field. Use only minimum power required to reach desired touchdown spot

24
Q

You have indication of insufficient rate of charge on the ammeter (and you’re not taxiing)

What should you do?

A

Test if it’s a nuisance trip out:

  1. Avionics master switch - off
  2. Alternator circuit breaker - in
  3. Master switch - both off and then on again
    - If the problem no longer exists, normal alternating charging will resume
  4. Avionics master switch may be turned on again

If the VOLT annunciator illuminates again, malfunction is confirmed and flight should be terminated. Minimize battery drain so you can use it for landing lights and flaps during landing.
