Operational and Ejection Emergency Procedures
The ejection system is designed to go through the
canopy whether or not the canopy is prefractured.
Ejection with the canopy in any position other than
fully closed and locked will involve contact of the
ejection seat and/or occupant with the canopy frame
resulting in seat malfunction and serious occupant
injury. If the canopy opens inadvertently in flight and
a controlled ejection is required, yaw the aircraft to
starboard to cause the canopy to depart the aircraft.

Minimum Safe Ejection
Purpose: to identify operating envelope of the
NACES ejection seat
Using the charts
NOTE: Minimum safe escape conditions are
those resulting in full inflation of the parachute
prior to ground contact.
(1) Determine which chart to use
NOTE: The following example uses
Figure 17-2 (1 of 3), "Minimum Safe
Ejection Altitudes: Aircraft Dive Angle
from Horizontal (0 degrees) to Vertical
(90 degrees)," in the NATOPS. The
procedure is similar for the other charts.
(2) Determine where dive angle (vertical line)
intercepts speed curve (i.e., 40 degrees
and 400 KIAS)
(3) From this intersection, move left to
determine minimum AGL altitude to initiate
ejection (approx 800 ft)
