(b)
Pull Up and Escape Capabilities
(Power Off) Carrier. (Figure 2)
Pull Up Discussion. (Figure 3)
(c)
(d)
Minimum Ejection Altitude (Terrain Clearance)
vs. Velocity & Flight Path. (Figure 4)
Minimum Ejection Altitude (Terrain Clearance)
(e)
vs. Velocity and Aircraft Attitude. (Figure 5)
Landing and Take-off Escape Capability. (Figure 6)
(f)
Pull Up and Escape Capabilities (Power Off) Land - The chart
3.2.2.1
(illustrated in Figure 1) shall depict for normal take-offs and landing patterns,
including final approach for aircraft operations from airports those areas in which
pull-up is effective in improving escape capability, in which pull-up is ineffective,
and in which ejection is not recommended.
Pull Up and Escape Capabilities (Power Off) Carrier - The
3. 2.2.2
chart (illustrated in Figure 2) shall depict for normal take-offs and landings, in-
cluding final approach, for aircraft operating from carriers those areas in which
pull-up is effective in improving escape capability, in which pull-up is ineffective,
and in which ejection is not recommended.
Pull Up Discussion - Pull up discussions, based upon aircraft
3. 2.2.3
flight characteristics shall discuss, as shown in Figure 3, advantages and dis -
advantages/problems associated with pull -up attempts to gain altitude to improve
inflight aircrew escape capability under various flight conditions.
Minimum Ejection Altitude (Terrain Clearance) vs. Velocity
3. 2.2.4
& Flight Path - The chart, illustrated in Figure 4, shall present curves depicting
minimum safe terrain clearance vs. aircraft velocity at time of escape initiation
for constant aircraft dive angles of O, 15, 30, 45, 60, and 90 degrees each.
Minimum Ejection Altitude (Terrain Clearance) vs. Velocity &
3.2. 2.5
Aircraft Attitude - The chart, illustrated in Figure 5, shall present curves de-
pitting minimum safe terrain clearance vs. aircraft velocity at the time of escape
