6.2.4 Additional information to engine failure and emergency landing procedures
If the engine failure occurs during the take-
off run, the pilot’s main concern should be to stop the aircraft
on the remaining runway. Those extra items in the checklist are to add protection should the runway be
too short to stop.
In-flight, prompt reduction of pitch attitude to obtain and maintain a proper glide speed upon experiencing
an engine failure is the first priority. If the failure has occurred shortly after take-off, a landing should be
planned straight ahead with only small changes in the flight direction to avoid obstacles. The best gliding
ratio can be achieved with flaps up
– flaps down will decrease the stall speed but at the same time reduce
gliding performance. Try to stop rotation of propeller if restarting efforts are not successful
– a windmilling
propeller has higher drag than a stopped propeller.
While gliding towards a selected forced landing site, an effort should be made to determine and correct
the cause of engine failure
– time and altitude permitting. Do not concentrate on the cause of the engine
failure or attempt an engine restart unless you have selected a suitable landing site and have sufficient
altitude and time. Flying the aircraft (especially maintaining the proper gliding speed) is always the first
priority. If the cause cannot be determined and corrected the emergency landing must be accomplished.
Always announce your intentions and position after engine failure using radio and other equipment when
time permits. Turn radio to international emergency frequency
– 121.5 and transmit MAYDAY message.
Activate Emergency Locator Transmitter (ELT)
– set the switch to ON position. Set transponder (XPDR) to
emergency code 7700. When the above mentioned procedure cannot be performed due to time
constrains, try to complete as many steps as possible. Transmitting MAYDAY message on the frequency
already tuned on your radio should be the minimum procedure.
WARNING
During a landing it is vital for the pilot to continue to fly the aircraft. Damage
and/or injuries can be minimized if the pilot is fully concentrating on controlling
the aircraft until it comes to complete stop
6.2.5 Carburetor icing
Carburetor icing mostly occurs when getting into an area of ice formation. The carburetor icing shows
itself through a decrease in engine power. To recover the engine power, the following procedure is
recommended:
- carburetor heating
ACTIVATE
- airspeed
75 MPH
- throttle
1/3 of power
(3500 RPM)
- if possible, leave the icing area
- increase gradually the engine power to cruise power after 1 - 2 minutes.
- if you fail to recover the engine power, land on the nearest airfield (if feasible), or, depending on
circumstance, off-airfield, following the procedure given under 6.2.2
