CESSNA
MODEL 172S NAV III
NORMAL PROCEDURES
NOTE
• In a left slip maneuver, the airspeed indicator may show
a maximum of 20 knots below the actual airspeed. In a
right slip maneuver, the airspeed indicator may show a
maximum of 5 knots above the actual airspeed. This is
because of the single static pressure port on the 172S
left forward fuselage.
• At airspeeds greater than 120 KIAS, close the throttle if
necessary to keep engine speed below 2700 RPM.
In the event of GPS failure when operating along routes that are
±
5 km
wide without VORlDME facilities and no NDB coverage, airplane
position between the width of such routes can only be assured up to
approximately 140 km from the last known position.
The pilot is to disregard Supplement 1 of the POH/AFM describing the
pointer Model 3000-11 or 4000-11 Emergency Locator Transmitter
(ELT).
