Mooney Aircraft MARK 21 - Take-off, Climb, and Cruise Operations

TAXllNG AND GROUND OPERAT $ON
The nose gear of the Mark 21 is linked directly to the rudder
pedals to provide stwring. The brakes may be applied fndepen-
demly to assist steering for sharper turns.
Caution should be
used when operatfng on rough terrain, R is
recommendd that minimum power be us& for starting to taxi
on sod or gravel fields. Too much power
will cause the propeller
to
suck up stones and thus nick the blades. Excessive speA
aver rough ground should be avoided to greclsadle pitch dom of
the nose.
The Lyeomirag 0-368- A 113s is an air pressure cooled engine that
depends on the forward speed of the airplane to maintain proper
cooling,
