C-27J general Flashcards
Land as soon as possible:
Emergency conditions are urgent and require an immediate landing at the nearest suitable airfield, considering also other factors such as weather conditions and aircraft weight.
Land as soon as practical:
Emergency conditions are less urgent. Aircrews use their best judgement to determine if the flight may be safely continued to an airfield where more adequate facilities are available.
Emergency Signal: Abandon Airplane
Abandon Airplane - one long sustained blast
Emergency Signal: Bailout
Bailout, Prepare - three short blasts
Bailout - One long sustained blast
Emergency Signal: Ditching or Crash Landing
Ditching or crash landing imminent - six short blasts
Emergency Signal: Brace For Impact

ACAWS
Advisory, Caution, and Warning System (ACAWS)
How many ACAWS alert levels?
Four: Special Alerts, Warnings, Cautions, Advisories
Special Alerts
Alert the crew of a flight-critical condition that must be corrected to preclude loss of or damage to the aircraft. Most special alerts require an immediate crew response and may have priority over Warning, Caution, and Advisory messages.
Warnings
Alert the crew for emergency operation or aircraft system conditions that require immediate corrective or compensatory crew action to prevent personal injury or loss of life. ACAWS warnings are displayed in RED and at the top of the ESA display.
Cautions
Alert the crew for abnormal operational or aircraft system conditions that require corrective or compensatory crew action to prevent damage to airplane. ACAWS cautions are displayed in YELLOW and are listed after warnings on the ESA display.
Advisories
Alert the crew for operational or aircraft system conditions that may require crew action. ACAWS Advisories are displayed in white and are listed after cautions on the ESA display.
Meaning of term “FAIL”
FAIL is used to indicate when the communication from equipment to 1553 data bus is lost. In this case, the equipment functionality is completely lost.
Meaning of term “FAULT”
FAULT is used when the equipment BIT detects an anomaly. In this case, the equipment functions could be unreliable.
Aural Characteristics of Warning
Sweeping Tone, Continuous until cancelled or cause corrected, press either MASTER WARNING switch light
Aural Characteristics of Caution
Two sets of complex tone, repeats at 7 sec interval until cancelled or cause corrected, press either MASTER CAUTION switch light
