indicated airspeed have been approved.
The recommended pre-air start check procedure is:
1.
Propeller Lever – Anywhere in operating range.

Propeller feathering is dependent on circumstances and is
at the discretion of the pilot. Fine pitch selection will pump
air through the engine, and; therefore increase the gas
generator motoring speed during the Air Start procedure.
