G100. BIRD STRIKE
Bird strikes can occur during virtually any stage of the flight. The most common times are
during takeoffs, landings, approaches, and low-levels. When birds hear the high pitch sounds of
approaching jet engines, they instinctively tuck their wings and dive. The area in which birds
pose the most danger, the bird strike zone, is the area between 11 and 1 o'clock, from slightly
above the horizon to 30º above the horizon. If a bird is seen in this zone, call it immediately,
"Bird", followed by position using clock code (e.g., "Bird, 1 o'clock!"). The P will then initiate
action to avoid the bird. Clock codes are essential so the P will be able to immediately acquire
the bird visually. If you see a bird that is not in the zone, don't say anything.
If a bird strike does occur, it usually will not cause any major problems. In the event a bird is
ingested into one of the engines, noises from the engine or a visual check may indicate the need
to shut down the engine. If the radome is struck, it could shatter, which would require a reduced
airspeed. The windshield though, is the primary danger area.
If the windshield does break, the cockpit will become extremely noisy from windblast (cockpit
communication difficult), and there is the possibility the P or Pilot Not Flying (PNF)/CP will be
incapacitated. If this should occur, the remaining crewmember must positively direct the
aircraft away from the ground. The flight will immediately return to base when a bird strike of
any kind occurs.
G101. LOST AIRCRAFT
The standard for maintaining course on a low-level is + 2 NM. If the aircraft becomes lost,
follow these procedures:
Climb to an appropriate VFR altitude.
Fix the position of the aircraft either visually or with a NAVAID fix.
Expect to reenter the route at an alternate entry point (fuel permitting) or discontinue
If aircraft position cannot be determined, execute lost plane procedures.
