CAPS might be appropriate. This list is not intended to be exclusive,
but merely illustrative of the type of circumstances when CAPS
deployment could be the only means of saving the occupants of the
aircraft.
Mid-air Collision
A mid-air collision may render the airplane unflyable by damaging the
control system or primary structure. If a mid-air collision occurs,
immediately determine if the airplane is controllable and structurally
capable of continued safe flight and landing. If it is not, CAPS
activation should be considered.
Structural Failure
Structural failure may result from many situations, such as:
encountering severe gusts at speeds above the airplane’s structural
cruising speed, inadvertent full control movements above the
airplane’s maneuvering speed, or exceeding the design load factor
while maneuvering. If a structural failure occurs, immediately
determine if the airplane is controllable and structurally capable of

continued safe flight and landing. If it is not, CAPS activation should be
considered.
Loss of Control
Loss of control may result from many situations, such as: a control
system failure (disconnected or jammed controls); severe wake
turbulence, severe turbulence causing upset, severe airframe icing, or
sustained pilot disorientation caused by vertigo or panic; or a spiral/
spin. If loss of control occurs, determine if the airplane can be
recovered. If control cannot be regained, the CAPS should be
activated. This decision should be made prior to your pre-determined
decision altitude (2,000’ AGL, as discussed below).
Landing Required in Terrain not Permitting a Safe Landing
If a forced landing is required because of engine failure, fuel
exhaustion, excessive structural icing, or any other condition CAPS
activation is only warranted if a landing cannot be made that ensures
little or no risk to the aircraft occupants. However, if the condition
occurs over terrain thought not to permit such a landing, such as: over
extremely rough or mountainous terrain, over water out of gliding
distance to land, over widespread ground fog or at night, CAPS
activation should be considered.
Pilot Incapacitation
Pilot incapacitation may be the result of anything from a pilot’s medical
condition to a bird strike that injures the pilot. If this occurs and the
passengers cannot reasonably accomplish a safe landing, CAPS
activation by the passengers should be considered. This possibility
should be explained to the passengers prior to the flight and all
appropriate passengers should be briefed on CAPS operation so they
could effectively deploy CAPS if required.
General Deployment Information
Deployment Speed
The maximum speed at which deployment has been demonstrated is
135 KIAS. Deployment at higher speeds could subject the parachute
and aircraft to excessive loads that could result in structural failure.
Once a decision has been made to deploy the CAPS, make all
reasonable efforts to slow to the minimum possible airspeed. However,

if time and altitude are critical, and/or ground impact is imminent, the
CAPS should be activated regardless of airspeed.
Deployment Altitude
No minimum altitude for deployment has been set. This is because the
actual altitude loss during a particular deployment depends upon the
airplane’s airspeed, altitude and attitude at deployment as well as
other environmental factors. In all cases, however, the chances of a
successful deployment increase with altitude. As a guideline, the
demonstrated altitude loss from entry into a one-turn spin until under a
stabilized parachute is 920 feet. Altitude loss from level flight
deployments has been demonstrated at less than 400 feet. With these
numbers in mind it might be useful to keep 2,000 feet AGL in mind as a
cut-off decision altitude. Above 2,000 feet, there would normally be
time to systematically assess and address the aircraft emergency.
Below 2,000 feet, the decision to activate the CAPS has to come
almost immediately in order to maximize the possibility of successful
deployment. At any altitude, once the CAPS is determined to be the
only alternative available for saving the aircraft occupants, deploy the
system without delay.
Deployment Attitude
The CAPS has been tested in all flap configurations at speeds ranging
from Vso to Va. Most CAPS testing was accomplished from a level
attitude. Deployment from a spin was also tested. From these tests it
