INTRODUCTION

MODEL
M20J
Performance data charts on the following pages are presented so that the
pilot can derive the information needed to plan flights with reasonable ac-
curacy. The performance data and charts presented are calculated based
upon actual flight tests
,
using average piloting techniques, the airplane and
engine in good condition and the engine power control system properly ad-
justed. The flight test data has been corrected to international standard at-
mosphere conditions and then expanded analytically to cover various
airplane gross weights, operating altitudes and outside air temperatures.
It is not possible to make allowances in the charts for varying levels of pilot
technique, proficiency or environmental conditions. The effect of soft run-
ways, winds aloft or airplane configuration changes must be evaluated by the
pilot. However, the performance data on the charts can be duplicated, by fol-
lowing the stated procedures, in a properly maintained, standard
M20J.
Mechanical or aerodynamic modifications to the aircraft are not authorized
since they can affect the performance or flight characteristics of the aircraft.
USE
OF
PERFORMANCE CHARTS
Performance data is presented in tabular or graphical form to illustrate the ef-
fect of different variables. Example problems are shown on each chart to
demonstrate how each chart is used. Only on those charts whose use is ob-
vious is no example given.
Generally, three items are required before entering each performance chart:
(1)
aircraft weight, (2) outside air temperature and (3) aircraft pressure al-
titude. The aircraft weight can be calculated utilizing the information provided
in Section
VI of this handbook. Outside air temperature is obtained by read-
ing the OAT gauge in the instrument cluster. Set the aircraft's altimeter to
29.92 in.
Hg. and read the indicated (pressure) altitude. (BE SURE TO
RETURN THE ALTIMETER
TO
THE LOCAL BAROMETRIC PRESSURE SET-
TING AFTER OBTAINING PRESSURE ALTITUDE).
Performance information derived by extrapolation beyond the limits shown on
the charts should not be used for flight planning purposes. REMEMBER--To
get chart performance, follow the chart procedures.
OPERATIONAL PROCEDURES
FOR MAXIMUM FUEL
EFFICIENCY
For maximuim fuel efficiency in the
MZOJ, proper mixture leaning during
cruise flight must be accomplished. The 10-360-A3B6D engine in the M20J
has been designed to attain maximum fuel efficiency, at desired cruise power,
at
14'~ rich of peak EGT.
