Lost communication procedures

ICS failure procedures

  1. Cords, switches, and connections for proper position and condition.
  2. Volume knob on the audio panel. Ensure it is full vol.
  3. Hot mike (HM) communications attempts.
  4. Shout or pass notes.
  5. If front pilot wants to transfer the controls aft, he will
    Pat his helmet and then point to the aft pilot. The pilot taking control will:
    Shake the stick to signify assuming control. The front pilot will
    Lift his hands above his shoulders to confirm.
  6. If rear pilot wants to transfer the controls aft, he will:
    Shake the stick to signify assuming control. The front pilot will
    Lift his hands above his shoulders to confirm he has given controls.
    Rear pilot will shake again.
  7. Mirrors if necessary.

Radio failure procedures

  1. Squawk 7600
  2. PRC-90 Attempt communications.
  3. ATIS on VOR 114.00
    Fly over
    NAS Corpus at 3,500' to determine duty runway - by looking for aircraft in the pattern or in the in the ground runup, or wind direction of windsock.
  4. Radio calls in the blind
  5. Rock wings when inbound for the break.
  6. On Short final: look for ALDIS lamp signals. If none, WAVEOFF, if no ALDIS lamp signals on second pass,
    Land if the runway is clear.

Generator Failure

  1. Starter Switch ..................................... OFF (Both cockpits)
  2. Generator Switch ................................ ON (Reset)
    If annunciator remains illuminated:
  3. Electrical Control ................................. TAKE COMMAND
  4. Generator Switch ................................. ON (Reset)
    If generator does not return to line:
  5. Electrical Load...................................... Reduce
  6. Land As Soon As Practical

- Complete loss of electrical power: Instrument flight NOT possible.
- Operating on battery power <20 min.

Inverter #1 or #2 Failure
If inverter annunciator and master caution illuminate:

  1. Other Inverter ............................................ SELECT
    If annunciator remains illuminated:
  2. Electrical Control ....................................... TAKE COMMAND
  3. 115-VAC, 1A Circuit Breaker.................... IN
  4. Inverter control relay circuit breaker ........... IN

Battery failure - low voltage reading
If the generator is functioning normally, battery failure may be indicated by smoke and fumes emitting from the battery box or abnormal, high charging rates. Failed battery cannot be restored.

On ground
a) Battery switch - OFF
b) Return to parking spot and secure
In flight
a) Battery switch - OFF
b) Until landing, maintain normal flight procedures. Land as soon as practical.

Interior light failure in flight
With the lights extinguished:
a) Activate and use utility/emergency light
b) Check corresponding circuit breakers - IN
c) Check corresponding switches - ON

Restoring electrical power
If the fire extinguishes, use the following procedure to activate essential circuits, allowing sufficient interval to isolate the faulty circuit:

  1. Utility bus switches - OFF
  2. Essential bus circuit breakers - PULL (2/7, 13, 3/4, 7)
  3. All electrical and avionics switches - OFF (UHF, inverters, TACAN, VOR, transponder, avionics master)
  4. Battery switch - ON
  5. Generator switch - ON/RESET (OFF if faulty)
  6. Avionics master switch - ON
  7. Avionics & electrical equipment essential to continued flight ON.

New Maneuvers for this event:

Outlying Field Break
An overhead transition, with interval, from cruise to the downwind configuration.
Break altitude - ________ ft at OLFs, __________ ft at Waldron

Break Interval - You are #1 for the break when:

  1. The aircraft ahead is:
    a. Turning crosswind
    b. Has completed at least 90° of turn and is abeam or behind your wingtip
  2. The aircraft ahead is:
    a. On downwind
    b. At least 15° behind your wingtip
  3. The aircraft ahead is:
    a. Departing in accordance with course rules
    b. Executing a simulated LAPL
  4. At a tower controlled field:
    a. All the above conditions are met
    b. You are cleared by the tower

Pattern Interval

No Flap Landing: When the aircraft ahead is abeam or behind your wingtip
Full Flap Landing: Same as break interval rules except that you may begin your turn when the aircraft on downwind is 15° ahead of your wingtip

Landing Pattern:

  1. The Break, IAW course rules:1000’ AGL, 170 KIAS, WTD on pattern side.
    FLOP 45°
    CHOP 300 ft-lb
    CHECK below 150 KIAS...
    DROP Gear
