Proper Strap-in -

The lap belt must be tightened first to prevent the buckle from moving

up toward the sternum when tightening the shoulder straps. If you cannot pull the lap belt tight
enough on your own, ask for assistance.

12.

The shoulder harness is to be secured such that neither strap can slide off the shoulder,

and be "snug" enough to prevent forward body movement while still allowing enough slack to
allow a thumb to slide under the strap.

13.

Final Confirmation -

Once properly strapped in, always confirm that the final

combination of cushions, spacers, and rudder adjustments, allows the front seat pilot to:

See the VON mark, with head at the level or chin tilted upward and with the
canopy closed;

Move the control column to its full forward stop;
