0.5.2 General Airspeed Terminology and Symbols
•CAS Calibrated Airspeed: the indicated speed of an aircraft corrected for position
and instrument error. Calibrated airspeed is equal to true airspeed in
standard atmosphere at sea level.
•KCAS: Calibrated Airspeed expressed in knots.
•IAS Indicated Airspeed: the speed of an aircraft as shown on the airspeed
indicator. IAS values in this manual assume zero instrument error.
•KIAS Indicated Airspeed expressed in knots.
•TAS True Air Speed: the airspeed of an aircraft relative to the undisturbed air
through which it passes.
•T.O.S.S Take-Off Safety Speed: the airspeed chosen to ensure that adequate control
will exist under all conditions, including turbulence and sudden and complete
engine failure during the climb after take-off. It is the speed required at 50
feet.
•VAManoeuvring Speed: the maximum speed at which application of full
available aerodynamic control will not damage or overstress the aircraft.
•VFE Maximum Flap Extended Speed: the highest speed permissible with wing
flaps in a prescribed extended position.
•VNE Never Exceed Speed: the limiting airspeed that may not be exceeded at any
time.

Jabiru Aircraft Pilot’s Operating Handbook
Model J120-C
JP-FM-10 Revision: 028 Nov 2007 Page 9 of 50
•VCMaximum Structural Cruising Speed: the speed that should not be exceeded
except in smooth air and then only with caution.
•VSStalling Speed: or the minimum steady flight speed at which the aircraft is
controllable.
•VSO Stalling Speed: or the minimum steady flight speed at which the aircraft is
controllable in the landing configuration.
•VXBest Angle-of-Climb Speed: the airspeed which delivers the greatest gain of
altitude in the shortest possible horizontal distance.
•VYBest Rate-of-Climb Speed: the airspeed which delivers the greatest gain in
altitude in the shortest possible time.
0.5.3 Meteorological Terminology
•OAT – Outside Air Temperature – the outside free air static temperature.
•Airfield Pressure Height – The height registered at the surface of an aerodrome by an
altimeter with the pressure sub-scale set to 1013 hPa (29.92 inches Hg).
•Pressure Altitude – Altitude measured from standard sea-level pressure (1013 hPa/29.92
inches Hg) by a pressure or barometric altimeter corrected for position and instrument error.
•Indicated Pressure Altitude – the altitude actually read from an altimeter when the
pressure barometric sub-scale has been set to 1013 hPa (29.92 inches Hg).
•QNH – The local pressure setting that if set on the subscale of an altimeter will cause the
altimeter to indicate local altitude above mean sea level.
•Wind – The wind velocities to be used as variables on aircraft performance are to be
understood as the headwind or tail wind components of the reported winds.
0.5.4 Aircraft Performance and Flight Planning Terminology
•Climb Gradient – The ratio of the change in height during a climb, to the horizontal
distance travelled.
•Demonstrated Crosswind Component – The crosswind component, during take-off and
landing, for which adequate control of aircraft was actually demonstrated during certification
tests.

0.5.5 Weight and Balance Terminology
•Datum – An imaginary vertical plane from which all horizontal distances are measured for
balance purposes.
•Station – A location along the aircraft fuselage usually given in terms of distance from the
reference datum.
•Arm – The horizontal distance from the reference datum to the centre of gravity (C of G) of
an item.
•Moment – The product of the weight of an item multiplied by its arm.
•Index Unit – Moment divided by a constant. Used to simplify balance calculations by
reducing the number of digits.
•Centre of Gravity (C of G) – The point at which an aircraft would balance if suspended.
The distance from the C of G to the reference datum can be found by dividing the total
moment by the total weight of the aircraft.
•C of G Arm – The arm obtained by adding the aircraft's individual moments and dividing
the sum by the total weight.
•C of G Limits – The extreme centre of gravity locations within which the aircraft must be
operated at a given weight.
•Useable Fuel – The quantity of fuel available for flight planning purposes.
•Unusable Fuel – The quantity of fuel (determined under adverse fuel flow conditions) that
is not available for flight.
•Empty Weight – Weight of aircraft with unusable fuel and full oil.
•Useful Load – Difference between take-off weight, and basic empty weight.
•Maximum Take-Off Weight – Maximum weight approved for take-off.

Grade: Avgas 100LL
Avgas 100/130
MOGAS with minimum Octane Rating of 95 RON1may be used.
Do not use fuel additives such as Octane Boosters.
NOTE
As there are significant variations possible even between automotive fuels with the same values
of RON, MON or AKI, Jabiru Aircraft strongly recommend using AVGAS. Automotive fuels
should only be used where AVGAS is not available, and if used, must have the highest anti-
detonation rating practically available.
CAUTION
In the J120-C Jabiru Aircraft allow the use of Ethanol additive to fuel up to a ratio of 10%.
However, owners must be aware of the additional operational risks and maintenance
requirements for using Ethanol additives. Section Error! Reference source not found. contains
