PARTICULAR PROCEDURES
UTILIZATION ON GRASS RUNWAY
CAUTION
THE SMALL WHEELS OF THE AIRPLANE AND ITS WEIGHT MAY
LEAD IT TO SINK IN SOPPY OR LOOSE GROUND
Before planing the landing, ensure that the field is hard, smooth and dry
enough. Landing and, a fortiori, takeoff shall not be envisaged if any doubt
exists about the condition of such a runway.
Particular directives
TAXI / TAKEOFF
1 –”INERT SEP” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
2 – Reverse Do not use. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
In fact, on a flat runway with grass, it is necessary to adopt a power
greater than the one obtained when the power lever is set to IDLE, so
the pilot will not be tempted to use the reverse.
LANDING
1 –”INERT SEP” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
After wheel touch down :
2 – Reverse Only if necessary. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
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).
