spin.
b. The best way to prepare for an engine out
procedure is to practice, practice, and practice until
the real thing is a non-event.
2. LOSS OF CONTROL. Another emergency
procedure the FLIGHT TEST PLAN should address
is sudden loss of a control function such as ailerons/
spoilers (roll), rudder (yaw), or elevator (pitch). In
all emergency situations, all corrective control movements
should be small and slowly initiated.
a. Loss of rudder authority or a jammed rudder
can usually be overcome with opposite aileron.
Be advised this is a cross control situation. Large
or rapid control inputs could initiate a stall/spin
maneuver, especially when the ultralight is in a landing
configuration and/or operating at a low airspeed.
b. Loss of ailerons authority usually can be
overcome with rudder. The turns should be shallow
while avoiding rudder inputs that would generate
large yawing movements.
c. Loss of the elevator is the most serious loss
of control function a pilot can experience. If the
elevator is jammed in one position, or remains in
a trail position behind the horizontal stabilizer, the
pilot must experiment with engine power to determine
whether an increase in power will raise or lower
the nose.
3. CATASTROPHIC FAILURE.
a. The chance of loss of life or personal injury
due to a catastrophic failure of the ultralight can be
reduced with a ballistic recovery system (see chap.
1, sec. 3). If control of the ultralight cannot be
regained, and the ultralight is equipped with a ballistic
chute, deploy the chute before running out of time
and altitude.
(1) The pilot must be sure that activation
of the parachute is a better choice than any other
options available. Once the canopy is deployed, the
pilot becomes a passenger.
(2) Even with a canopy deployed, however,
the pilot must remain alert to the danger of
power lines, trees, rocks, water, and highways below
which may obstruct his/her attempt to safely land.
