leveled.
With wings level and no sink rate, ejection is feasible within the following parameters:
1. Ground level - zero airspeed.
2. Surface to 50,000 ft MSL - 600 KCAS maximum.
Ejection at low altitude allows only a matter of seconds to prepare for landing. Over water, inflation
of the LPU is the most important step to be accomplished. Release of the parachute quick-release
fittings as the feet contact the water is the second most important step to prevent entanglement in the
parachute shroud lines.
When ejection is in the immediate vicinity of the carrier, parachute entanglement combined with
wake and associated turbulence can rapidly pull a survivor under. The deployed seat survival kit may
contribute to shroud line entanglement. Be prepared to cut shroud lines if the parachute is dragging
the survivor.

The crashed aircraft may release large quantities of jet fuel and fumes which could hamper breathing
and/or create a fire hazard. If jet fuel is present, do not use a flare marker. The emergency oxygen
system may be invaluable in this case. If emergency oxygen is required, do not discard the survival kit,
as this terminates the availability of emergency oxygen. However, totally discarding the survival kit
may be appropriate after considering weather, sea conditions, and rescue potential.
Low altitude ejection may result in parachute canopy disintegration due
to the aircraft impact fireball.
The variety and complexity of conditions encountered during the ªtime criticalº actions following a
low altitude, overwater ejection make it impossible to formulate procedures to cover every contingency.
17.1.3 High Altitude Ejection. The basic low altitude procedure is applicable to high altitude
ejection. The zoom is useful to slow the aircraft to a safer ejection speed or to provide more time and
glide distance if immediate ejection is not necessary. If the aircraft is descending out of control, eject
by 6,000 feet AGL. Even if under control, do not delay ejection below 2,000 feet AGL. Head the aircraft
toward an unpopulated area, if possible.
17.1.4 Ejection Procedures. See figure 17-4.
17.2 DITCHING
In the event ejection has failed and the aircraft must be ditched, see figure 17-5.
17.3 SEAWATER ENTRY
If downed in seawater, SEAWARS releases the parachute canopy within 2 seconds. However, if able,
manually unlock each canopy release immediately on seawater entry. The SEAWARS does not operate
in freshwater.

EJECTION INJURIES AND BODY POSITIONING
THESE PROPER BODY POSITIONS
MUST BE TAKEN TO PREVENT INJURIES
1. Press head firmly against headrest.
2. Elevate chin slightly (10¡).
3. Press shoulders and back firmly against seat.
4. Hold elbows and arms firmly towards sides.
5. Press buttocks firmly against the seat back.
6. Place thighs flat against seat.
7. Press outside of thighs against side of seat.
8. Place heels firmly on deck, toes on rudder pedals.
EJECTION INITIATION
There are two acceptable methods for ejection initiation; the two-hand grip and the single-hand grip.
Two-hand method -
1. Grip the ejection handle with the thumb and at least two fingers of each hand, palms toward body.
Keep elbows close to body.
Single-hand method -
1. Grip handle with the strong hand, palm toward body. Grip wrist of strong hand with other hand, palm toward
body. Keep elbows close to body.
Both methods -
2. Pull handle sharply up and toward abdomen, keeping elbows in. Ensure handle pulled to end of travel. Continue
