NOTE
*Speed performance is shown for an airplane equipped with
speed fairings which increase the speeds by
approximately 2 knots. There is a corresponding difference
in range, while all other performance figures are
unchanged when speed fairings are installed.
The above performance figures are based on airplane weights at 2450
pounds, standard atmospheric conditions, level, hard-surfaced dry
runways and no wind. They are calculated values derived from flight
tests conducted by Cessna Aircraft Company under carefully
documented conditions and will vary with individual airplanes and
numerous factors affecting flight performance.

when the airplane was delivered from the factory and should be used to
replenish the supply during the first 25 hours. This oil should be drained
and the filter changed after the first 25 hours of operation. Refill the
engine with MIL-L-6082 or SAE J1966 Aviation Grade Straight Mineral
Oil and continue to use until a total of 50 hours has accumulated or oil
consumption has stabilized.

SYMBOLS, ABBREVIATIONS AND TERMINOLOGY
GENERAL AIRSPEED TERMINOLOGY AND SYMBOLS
KCAS Knots Calibrated Airspeed is indicated airspeed corrected
for position and instrument error and expressed in knots.
Knots calibrated airspeed is equal to KTAS in standard
atmosphere at sea level.
KIAS Knots Indicated Airspeed is the speed shown on the
airspeed indicator and expressed in knots.
KTAS Knots True Airspeed is the airspeed expressed in knots
relative to undisturbed air which is KCAS corrected for
altitude and temperature.
VAManeuvering Speed is the maximum speed at which full or
abrupt control movements may be used without
overstressing the airframe.
VFE Maximum Flap Extended Speed is the highest speed
permissible with wing flaps in a prescribed extended
position.
VNO Maximum Structural Cruising Speed is the speed that
should not be exceeded except in smooth air, then only with
caution.
VNE Never Exceed Speed is the speed limit that may not be
exceeded at any time.
VSStalling Speed or the minimum steady flight speed is the
minimum speed at which the airplane is controllable.
VSO Stalling Speed or the minimum steady flight speed is the
minimum speed at which the airplane is controllable in the
landing configuration at the most forward center of gravity.
VxBest Angle of Climb Speed is the speed which results in
the greatest gain of altitude in a given horizontal distance.
VYBest Rate of Climb Speed is the speed which results in the
greatest gain in altitude in a given time.
