lift or convective activity, do not attempt to maintain a
constant altitude. This will result in airspeed
increases, possibly exceeding Vne of the glider, and
make it extremely difficult for the glider pilot to avoid
developing slack in the tow rope. If traffic, terrain, and
airspace considerations allow, it is generally best to
maintain a constant airspeed and accept moderate
variations in altitude.
WARNING
Should high sink rates be encountered requiring the
establishment of a climb, advance the throttle as
required. In extreme circumstances it may also be
necessary to advance the propeller RPM to achieve
an adequate rate of climb.
SEVERE WEATHER OPERATIONS
Rain
71.
No special precautions need to be taken during flight in rain other than remaining vigilant
for icing conditions and unexpected reductions to visibility. During take-off and landing,
directional control may be more difficult as a result of reduced friction both on paved and grass
surfaces. Both take-off and landing should be flown with a nose high attitude on grass surfaces
as unseen heavy wet grass or deep puddles could cause wheel-barrowing.
Icing Conditions
WARNING
Flights into conditions where icing should reasonably be
expected are prohibited
. This specifically includes flight in
freezing rain or freezing drizzle, flight in wet snow, or flight in
clouds.
72.
This aircraft is not equipped for flight in icing conditions. There is no anti or de-icing
equipment for the airframe, propeller, engine air induction system. In the event that icing
conditions are inadvertently encountered, pilots must consider the following points and
complete the Flight In Icing Conditions Checklist contained in the Emergency Procedures
Section:
a.
turn back or change altitude to achieve an outside air temperature that is less
conducive to icing;
b.
should the static system become blocked, or erroneous airspeed, altimeter or
vertical speed indicator readings be suspected, the alternate static air valve
should be pulled open to supply static air from the cabin;
c.
cabin pressures vary with vents and windows open, and with airspeed. Therefore,
