3.3.11 Spins and Spiral Descents
Deliberate spinning is prohibited.
A spiral dive may develop after a stall if the bar is
maintained at the forward limit and a large roll rate
is allowed to develop. If this condition is not
corrected it will lead to large and increasing roll
attitudes (beyond the 60 degree limit). Increasing
attitude, increasing speeds and large control bar
feed back forces will occur. Incipient spiral dives
can be terminated at any time by rolling wings level.
If the spiral dive is allowed to develop to extreme
roll attitudes, recovery is expedited by relieving
control bar forces before rolling wings level and
recovering from high-speed condition.
3.3.12 Unusual Attitudes
Unusual attitudes where the nose is raised or lowered more than 45 degrees from the horizontal are to
be avoided. On recognising a situation where the aircraft is approaching these pitch angles proceed as
outlined below.
3.3.12.1 Nose High Attitude
To recover from the situation where the nose of the aircraft is pitched up more than 45 degrees from the
horizontal proceed as follows:
H H
old attitude - Do not attempt to pull control bar in
P Reduce P ower
O As energy dissipates the aircraft will rotate nose down - keep control bar O ut
P once the attitude lowers level the wings and increase P ower to prevent over pitching
R R ecover from dive and R esume desired flight path
3.3.12.2 Nose Down Attitude
To recover from the situation where the nose of the aircraft is pitched down more than 45 degrees from
the horizontal proceed as follows:
O Raise attitude - push O ut
P Apply P ower
R R ecover from dive and R esume desired flight path
3.3.13 Instrument Failure
Instrument failure may occur through an electrical fault or through exposure to High Intensity Radio Fields
(HIRF).
The aircraft is equipped with an analogue ASI as well as a digital engine management system. The
analogue ASI will not be effected by either an electrical fault or HIRF. If there is a problem with the digital
system the correct procedure is to fly to the nearest safe landing area and investigate the cause of the
malfunction.
WARNING
DO NOT ATTEMPT TO SPIN THE AIRCRAFT.

DIVES SHOULD NOT BE
ATTEMPTED.
