Unusable
2 U.S. GAL
The unusable fuel for this airplane has been determined as 1.0 gallon in each wing in critical flight attitudes
Takeoff Checklist
Fuel on proper tank, Electric fuel pump on, Engine gauges checked, Flaps-set, Carb. heat off, Mixture set, Seat backs erect, Fasten belts/harness, trim tab-set, Controls-free, Door-latched
Landing Checklist
Fuel on proper tank, mixture rich, Electric fuel pump on, Seat backs erect, Flaps-set (White Arc), Fasten belts/harness
auxiliary vacuum system
is limited to standby function only. Take off with the engine driven dry air pump inoperative is not approved
Vacuum pressure limitations
Discontinue flight in instrument meteorological conditions (IMC) if vacuum pressure falls below 4.8 In. Hg.
The auxiliary pump/motor
Auxiliary pump/motor assembly and elapsed time indicator must be removed from service after 500 hours accumulated operating time or 10 years, whichever occurs first
ELT
The Emergency Locator Transmitter (ELT), when installed, is located in the aft portion of the fuselage just below the stabilator leading edge and is accessible through a plate on the right side of the fuselage. This plate is attached with slotted-head nylon screws for ease of removal; these screws may be readily removed with a variety of common items such as a dime, a key, a knife blade, etc. If there are no tools available in an emergency, the screw heads may be broken off by any means. The ELT meets the requirements of FAR 91.52.

Indicated Pressure Altitude
T h e n umber actually read from an
Altitude altimeter when the barometric subscale has
been set to 29.92 inches of mercury (1013.2
millibars)
Pressure Altitude
Altitude measured from standard sea-level
pressure (29.92 in. Hg) by a pressure or
barometric altimeter. It is the indicated
pressure altitude corrected for position and
instrument error. In this handbook,
altimeter instrument errors are assumed to
be zero.
Station Pressure
Actual atmospheric pressure at field
Reference Datum
An imaginary vertical plane from which all
horizontal distances are measured for
balance purposes
Station
A location along the airplane fuselage usually given in terms of distance from the reference datum
Arm
The horizontal distance from the reference
datum to the center of gravity (C.G.) of an item.
Moment
The product of the weight of an item
multiplied by its arm. (Moment divided by
a constant is used to simplify balance
calculations by reducing the number of
digits.
Center of Gravity (C.G.)
The point at which an airplane would balance if suspended. Its distance from the
reference datum is found by dividing the
total moment by the total weight of the
airplane.
C.G. Arm
The arm obtained by adding the airplane’s individual moments and dividing the sum by the total weight
C.G. Limits
The extreme center of gravity locations within which the airplane must operated at a given weight
Standard Empty Weight
Weight of a standard airplane including unusable fuel, full operating fluids and full oil.
Payload
Weight of occupants, cargo and baggage
Maximum Ramp Weight
Maximum weight approved for ground
maneuver. (It includes weight of start, taxi
and run up fuel.)
Maximum Takeoff weight
Maximum weight approved for the start of the takeoff run
Maximum Landing Weight
Maximum weight approved for the landing touchdown
Maximum Zero Fuel Weight
Maximum weight exclusive of usable fuel
