g. Engage starter.
h. When out of feather, resynchronize engines.
If the engine has been inoperative for several minutes,
particularly in low temperatures, prime by turning the boost
pump
"ON"
and moving the mixture control forward until the
first indication of fuel pressure, then return to
"IDLE CUT·
OFF".
Leave boost pump
"ON"
and start as in (c).
The standard Aztec, operating at gross weight under opti-

turbulence and pilot technique, and under
standard conditions of temperature and altitude, has a single
engine absolute ceiling of 6400 feet at 5200 pounds and maximum ·
obtainable power.
Under ideal conditions, the Aztec can be expected to main-
tain approximately the stated maximum altitudes. When adverse
conditions of turbulence, temperature, altitude, pilot technique,
or airplane condition or equipment is encountered, the absolute
ceiling will be reduced. These factors must be taken into con-
sideration in the single engine operation of any twin engine
airplane.
Pilots of this airplane should remain reasonably proficient
in single engine flight. In many cases, "simulated" single
engine operation (zero thrust condition, approximately 10 inches
of manifold pressure and 2200 RPM) will be preferable, but
actual single engine operatioo should be practked occasionally.
The following precautions should be exercised in actual single
~~fli~:
.
a. Do not feather a propeller if there is reason to suspect
that the starting characteristics of the engme are not normal and
that restarting in the air may be difficult or impossible.
b. Do not feather a propeller in conditions of temperature,
altitude, weight or turbulence which may prevent single engine
flight at altitudes well above the local
~round
elevation.
c. Do not feather a propeller at any time when ·conditions
of terrain or other conditions may prevent the airplane from
reaching an airport easily, in case the dead engine .cannot be
