UTILIZATION ON GRASS RUNWAY

THE SMALL WHEELS OF THE AIRPLANE AND ITS WEIGHT MAY LEAD IT TO SINK IN
Before planning the landing, ensure that the field is hard, smooth and dry enough. Landing and moreover takeoff
shall not begin if any doubt exists about the condition of such a runway.

In fact, on a flat runway with grass, it is necessary to adopt a power greater than the one obtained when the
throttle is set to Flight IDLE, so the pilot will not be tempted to use the reverse.

Do not maintain reverse at speeds below 40 KIAS to avoid ingestion of foreign matter.
Indeed, under this speed, using the reverse makes a cloud of solid particles (dusts, sand, gravels, trocken grass,
and so on ...) appear around the front face of the airplane. This will damage the propeller and, after ingestion, the
engine internal components (compressor and turbine blades).
