INTRODUCTION
MODEL 560
ISA: International Standard Atmosphere in which:
a. The air is a dry perfect gas;
b. The temperature at sea level is 15°C (59°F);
c. The pressure at sea level (standard datum plane) is 29.92
inches Hg. (1013.2 Mb);
d. The temperature gradient from sea level to the altitude at
which the temperature is -56.6°C will be -1.98°C per 1000
feet.
ITT: Interstage Turbine Temperature. Engine operating temperature
taken between the high and low pressure turbine sections.
Jack Point: One of three points on the airplane designed to rest on a jack.
KCAS: Indicated airspeed (knots) corrected for position error (instrument
error is assumed to be zero).
kHz: Kilohertz
KIAS: Airspeed
indicator
reading
(knots). Zero instrument error is
assumed.
KTAS: True airspeed expressed in knots
Landing Distance: The distance from a point 50 feet above the runway surface to the
point at which the airplane would come to a full stop on the runway.
Lb: Pound
Lb/hr: Pounds-per-hour
LH: Left Hand
LSB: Lower Side Band
M or Mach: Mach Number. The ratio of true airspeed to the speed of sound.
MAC: Mean Aerodynamic Chord. The chord of an imaginary airfoil which,
throughout the flight range, will have the same force vectors as
those of the wing.
Maximum Brake Energy Speed: The maximum speed from which a stop can be accomplished within
the energy capabilities of the brakes.
Maximum Continuous Power: The power developed at 700°C ITT or 100.0 percent N
1
RPM,
which is the maximum power setting without a time limit. Used in
emergency conditions only.
Maximum Cruise Thrust Setting Maximum power setting recommended for cruise thrust.
Maximum Landing Weight: Maximum weight approved for landing touchdown.
Maximum Ramp Weight: Maximum weight approved for ground maneuver. It includes engine
start and taxi fuel.
Maximum Zero Fuel Weight: Maximum weight exclusive of usable fuel.
Mb: Millibars
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.)
