4. Dangerous situations and
extreme flying
Dangerous situations
Pilot error, extreme wind conditions or turbulence which goes unnoticed by the pilot for too
long may leave the wing in an unusual flying position, requiring special reaction and skills on the
part of the pilot. Any pilot who flies in turbulent conditions or who makes an error in handling the
glider is at risk of getting into an extreme situation. All of the extreme flight figures and flight
attitudes described here are dangerous if they are carried out with inadequate knowledge,
without the right safety altitude or without training.
In turbulent conditions, always keep enough distance from rock faces and other obstacles.
Time and sufficient altitude are needed to recover from extreme situations.
Always keep within the recommended limits. Avoid aerobatics and extreme loading such as
spirals and big ears. This will prevent accidents and avoid over-loading the glider.
Deploy your reserve if the corrective manoeuvres described in the following sections do not
return the glider to a controllable flying position or if there is not enough altitude for correction.
Ground-training is a safe and effective method of familiarising yourself with your glider’s
reactions. Launch can be practised, as can small flying manoeuvres, such as stall, asymmetric
collapse, front stall etc.
Safety training
Taking part in safety training is generally recommended so that you can familiarize yourself
with your glider and the correct reactions in extreme situations. However, safety training also
subjects your equipment to extreme loads.
Extreme flight manoeuvres with a motor
under full load are extremely dangerous and
therefore cannot be tested. In this section we
describe how to correct extreme situations in
the event that one should ever occur. The
manoeuvres below relate to the take-off
weight without motor and should help to
understand the behaviour of the glider.
The glider design is such that the following
flight manoeuvres cannot be performed in
terms of the certification test report:
• asymmetric collapse with open trimmers
• asymmetric collapse with open trimmers
and speed bar
• front stall with open trimmers
• front stall with open trimmers and speed
bar
