NORMAL PROCEDURES
4.14 SOFT FIELD OPERATIONS
Soft fields are runways that have rough or soft surfaces, such as sand, snow,
mud, or tall grass. Take o ff and landing procedures for soft field operations
are described in 4.5.1. and 4.9.
4.15 STALL
The stall recovery procedure is standard and recovery can be performed by
normal use of controls:
1 Control stick Forward, to r educe angle of attack
2 Power lever Add power
3 Horizontal flight Resume
Stall recovery is performed with average pilot skills, with less than 20° of
yaw or roll. The recovery maneuver generally requires less than 250 ft of
altitude drop.
The aircraft is equipped with a haptic stall warning system in control stick
handles that are activated as aerodynamic stall condition is imminent. An
aural warning is emitted by the EPSI570C speaker and is also heard in the
headsets.
Two stall types can be encountered when stalling the aircraft.
A-type stall: uncontrollable downward pitching motion (fully developed stall,
usually accompanied by wing drop).
C-type stall: the control stick reaches the rear stop position.
Depending on a combination of several factors like aircraft mass, flaps set-
ting, CG position, G-load, power setting and tempo of AOA increase/speed
reduction, the stall can be A-type or C-type.
