ACFT Damage Flashcards
Slight Vibrations
Would not be apparent to experienced aircrew unless their total attention was directed to the vibrations
Moderate Vibrations
Would be noticeable to experienced aircrew but it does not affect their work or concentration
Severe Vibrations
Immediately apparent to experienced aircrew and task performance can only be completed with difficulty
Intolerable Vibrations
Require aircrew’s sole preoccupation to reduce the vibration level
1) Rotor blade damage is known or suspected
AND
2) Secondary indications (such as vibrations) are more than moderate, flight characteristics are drastically altered
Rotor Blade Damage (More than Moderate) (pg 27-28)
1) Landing/Hover checklist - complete (200 foot checks at a minimum based on urgency)
2) Land/Ditch immediately
1) Rotor blade damage is known or suspected, with or without secondary indications of up to moderate
Rotor Blade Damage (up to Moderate) (pg 28-29)
1) Land as soon as possible
1) Severe or intolerable vibrations of unknown origin
Abnormal Vibrations (Severe/Intolerable) (pg 29-30)
1) Landing/Hover checklist - complete (200 foot checks at a minimum based on urgency)
2) Land/Ditch immediately
1) Moderate vibrations
Abnormal Vibrations (Moderate) (pg 29-30)
1) Cruise airspeed - 75-120 kias
2) Avoid abrupt maneuvers
3) Land as soon as possible
1) Slight vibrations
Abnormal Vibrations (Slight) (pg 29-30)
1) Cruise airspeed - 75-120 kias
2) Avoid abrupt maneuvers
3) Land as soon as practical
(Note: a reduction in airspeed may reduce vibrations and improve flight characteristics (weather, flight conditions, and distance from landing area permitting)
1) Either inner or outer pane on windscreen cracked
Windscreen Cracks (pg 31)
1) Cruise airspeed 70 knots maximum
2) If arcing on windscreen is noticed, secure windscreen anti-ice
3) Abort mission
1) Both inner and outer pane on windscreen cracked
Windscreen Cracks (pg 31)
1) Cruise airspeed 70 knots maximum
2) If arcing on windscreen is noticed, secure windscreen anti-ice
3) Land as soon as practicable
