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.
• VA Manoeuvring 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.

28 Nov 2007 Page 9 of 50
• VC Maximum Structural Cruising Speed: the speed that should not be exceeded
except in smooth air and then only with caution.
• VS Stalling 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.
• VX Best Angle-of-Climb Speed: the airspeed which delivers the greatest gain of
altitude in the shortest possible horizontal distance.
• VY Best 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 RON1 may 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 antidetonation 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
additional information.

4.2 Trim Sheets
A metric trim sheet has been provided. An example loading has been worked through for
reference.
4.2.1 Trim Sheet Index Units
To use the trim sheets the aircraft’s weight and balance information must be converted to “Trim
Sheet Index Units” using the formula below:
Trim Sheet Index Units = Aircraft Weight x (Arm – 1403)
1000
“Aircraft Weight” and “Arm” are written onto the aircraft’s Load Data Sheet.
For example, an aircraft with “Aircraft Weight” of 260kg and “Arm” of 1590mm has a Trim Sheet
Index Unit of 48.62 This is used for the starting point of using the Trim Sheets.
Calculate Aircraft Weights
1-1 Use the Aircraft Empty Weight obtained from the latest aircraft weighing records to
enter the vertical “Aircraft Empty Weight Scale” on right hand side of the chart.
1-2 Move horizontally to the left into the next scale which is the “Crew Weight” Scale.
1-3 Move vertically downward one line on this scale for each 10-kg of weight that is
placed on the front seats, and mark a point.
1-4 Move horizontally to the left from the point made in Step 1-3 to enter the next scale
which is the “Baggage Weight” Scale.
1-5 Move vertically downward one line on this scale for each 5-kg of weight that is placed
in Baggage Zone and mark a point.
1-6 Move horizontally to the left from the point made in Step 1-7 to enter the next scale
which is the “Fuel Quantity” Scale and mark a point, This point is the “Zero Fuel
Weight Reference Point”
1-7 Move Horizontally to the left of the “Zero Fuel Reference Point” and Mark a “Zero
Fuel Weight Line” across the “Aircraft Trim Condition” Graph.
1-8 From the “Zero Fuel Point” on the “Fuel Quantity Scale” (marked in Step 1-8), move
vertically downward one line for each 10-litres of fuel being carried at the take-off
condition. Mark this “Take-Off Fuel Point” on the scale.
1-9 Move horizontally to the left, and mark a “Take-Off Fuel Weight Line” across the
“Aircraft Trim Condition” graph.

Calculating the Operating CG Locations
2-1. Take the calculated Empty Weight Trim Index and mark it’s position on the Aircraft
Index Units Ladder at the top of the sheet.
2-2 Draw a vertical line down from the point marked above to intersect with a sloping line
in the “Crew Index Units” scale and mark this point.
2-3 Calculate the weight of the crew and round this value to the nearest 10-kg.
2-4 Move horizontally to the right from the point marked in Step 2-2 one line for each 10-
kg of load calculated. (i.e. 60-kg = 6 lines) and mark a point at this location.
2-5 Draw a vertical line down from the point marked above to intersect with a sloping line
in the Baggage Area scale and mark this point.
2-6 Calculate the weight that will be placed Baggage Area and round this value to the
nearest 5-kg.
2-7 Move horizontally to the right from the point marked in Step 2-5 one line for each 5-
kg of load calculated. (i.e. 20-kg = 4 lines) and mark a point at this location.
2-8 Drop a vertical line down from the point marked in Step 2-10 to intersect a sloping
line in “Fuel Chart”, and mark a point at this location.
2-9 Continue the Vertical Line began in Step 2-11 down to intersect with the “Zero Fuel
Weight Line” drawn in Step 1-7. mark this point as the “ZERO FUEL Condition”
2-10 Move horizontally to the right from the point marked in Step 2-11 in the “Take-Off
Fuel Box”, one line for each 10 liters of take-off fuel, and mark this point.
2-11 Move vertically downward from the take-off fuel point marked in Step 2-13 to
intersect with the “Take-Off Fuel Weight Line” marked in Step 1-9. Mark this point
the “Take-Off Condition”
4.2.2 Allowable Loading Conditions
An allowable loading condition exists when both the “Zero Fuel Condition”, and the “Take-Off
Condition” fall with the area bounded by the Line in the Aircraft Trim Conditions Box.
For reference, the example below shows two 80kg people, 5kg in Baggage Zone and 60L of fuel.
The aircraft’s starting Index Unit is 48.6 at 260kg.

6 SECTION 6 - EMERGENCY PROCEDURES
6.1 GENERAL
This Section describes the procedures to be adopted in the event of an emergency or abnormal
situation occurring in the J120-C aircraft.
The procedures are arranged in the sequence considered to be the most desirable in the majority
of cases. Steps should be performed in the order listed unless good reasons for deviation exist.
It should be remembered however, that all conceivable eventualities cannot be foreseen by the
manufacturer. Particular circumstances such as multiple or unanticipated emergencies, adverse
weather etc. may require modification to these procedures. A thorough knowledge of the aircraft
and its systems is essential to analyse the situation correctly and determine the best course of
action in any particular circumstance.
The following basic rules apply to all aircraft emergencies:
1. Maintain Aircraft Control.
2. Analyse the situation and take appropriate action.
3. Land as soon as practicable.
6.2 AIRSPEEDS FOR EMERGENCY OPERATIONS
Maximum Glide ……………………………………………. 65 KIAS*
Landing Without Engine Power (Flaps Full) …………… 60 KIAS
* - A slightly higher speed may give better distance over the ground if gliding into wind; a slightly
slower speed if gliding downwind.

6.3.2 Airstart & Limitations
In the event that the engine is stopped during flight, it may be restarted by application of fuel &
ignition, provided that the propeller is still windmilling. The propeller may stop windmilling below
50 KIAS
The Jabiru 2200 engine is a high compression (7.8:1) engine & therefore airstarts when the
propeller has stopped rotating, without the use of the starter, are unlikely before reaching VNE.
Therefore, the following procedure addresses only airstarts by use of the starter motor.
IMPORTANT – NO NOT depress starter button while propeller is rotating.
1. Ignition…………………………………………… OFF
2. Cabin…………………………………………….. CLEAR
3. Airspeed…………………………………………. REDUCE UNTIL PROPELLER
STOPS TURNING.
4. Establish Glide………………………………….. 65 KIAS
5. Fuel………………………………………………. ON
6. Fuel Pump………………………………………. ON
7. Master…………………………………………… ON
8. Ignition Switches……………………………….. ON
9. Starter Button…………………………………… Depress
10. Throttle…………………………………………... Open
11. Repeat as necessary, ensuring propeller has stopped before each restart attempt.
Notes: (a) If engine does not restart commence forced landing procedure.
(b) If clear symptoms of a mechanical failure exist, or if the engine has seized
due to the loss of oil pressure, do not attempt a restart.
(c) If engine operates with only L or R ignition selected, leave the ignition switch in
this position whilst a suitable landing area is selected.
(d) The engine cools quickly with the propeller stopped. Choke may needed to
achieve a start.

Intentional spins are prohibited in this aircraft. Should an inadvertent spin occur, the
following recovery procedure should be used:
1. Retard the throttle to idle
2. Centralise ailerons
3. Apply and hold full rudder opposite to the direction of rotation
4. Move stick progressively forward far enough to break stall
5. Hold these control inputs until rotation stops
6. As rotation stops, centralise rudder and make a positive, smooth recovery from
the resulting dive
WARNING
If the spin is encountered with flaps extended, DO NOT retract flaps until rotation ceases.
Premature flap retraction will delay recovery.

28 Nov 2007 Page 43 of 50
Before the first flight of the day the engine must be “pulled through” by hand. This is the process
of turning the engine over by turning the propeller by hand. The compression of each cylinder in
turn will be felt a resistance as the propeller is turned. The engine should be rotated for a count
of at least 8 compressions.
Master Switch............................................OFF
Ignitions.....................................................OFF
Throttle......................................................Closed
Propeller....................................................TURN by hand & observe engine for odd
noises or heavy movements. Check for
regular compression.
CAUTION:
Prior to pulling through the propeller by hand, the engine must be cold, both ignition circuits & the
Master Switch must be switched OFF, the brakes applied & throttle closed.
WARNING
A hot engine may fire with the ignition/s switched OFF.
DO NOT pull through a hot engine.
CAUTION
Several causes of irregular compression – such as poorly sealing valves – can lead to extensive
engine damage if not addressed. The Jabiru 2200 Engine Instruction & Maintenance Manual
provides additional details.

7.4.12 Engine Management – Ground Running
The 2200B engine fitted to the J120-C is cooled by air flowing over the engine and oil cooler.
During ground running care must be taken to ensure that there is adequate airflow and that safe
engine temperatures are maintained. The guidelines presented below will assist in controlling
temperatures.
• Minimise ground running times – especially in hot weather
4
.
• Carry out as many checks as possible before starting the engine.
• Always carry out engine run-up tests with the aircraft pointing into wind.
• In hot weather, after performing run-up checks, leave the aircraft pointing into wind and idling
at 1200rpm for 30 seconds to aid cooling.
• If the aircraft is required to wait – such as for runway clearance – temperatures must be
monitored, and if they approach ground running limits (listed in Section 2 of this flight manual
& displayed as yellow markings on engine gauges) the aircraft must be turned into wind or
shut down to prevent any further temperature increase.
• Wind must be coming from within approximately 45° of the aircraft heading to be effective in
aiding engine cooling.
• If there is no wind or low wind the engine must be shut down if ground-running temperature
limits are reached.

SECTION 8 – GROUND HANDLING & SERVICING
8.1 FUEL
• Avgas 100LL
• Avgas 100/130
• MOGAS with minimum Octane Rating of 95 RON
1
may 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, 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
Fuel additives containing alcohol (i.e. Ethanol etc) will damage the sealant used in the fuel tanks.
DO NOT use fuel with any level of added alcohol.
8.1.1 Fuel Ethanol Content
Jabiru Aircraft allow fuels with an Ethanol content of up to 10% to be used in the J120-C. While
Ethanol boosts the fuel’s octane rating and is becoming increasingly common in automotive fuels
there are important issues caused by its use. The following points are given as a basic
introduction to using Ethanol. Note that while this information was current at the time of writing.
• Use of a fuel with an Ethanol content higher than 10% IS NOT PERMITTED in the J120-C.
• Ethanol is hygroscopic (i.e. it will absorb water). This can be water vapour from the air,
condensation inside tanks or free water. While very small amounts of water can be
absorbed without significantly affecting the fuel’s combustion, at higher levels the mixture
will not be combustible. In addition, because this incombustible fuel is formed from a
mixture of the Ethanol in the fuel and the water it can have a large volume – so a small
amount of water will result in a much larger amount of incombustible Ethanol/water mix.
This may give false readings in the fuel tank sumps or exceed the volume of the sump
altogether.
• Ethanol mixed with water is somewhat corrosive and may attack fittings etc of the fuel
system.
• In long-term storage, Ethanol may oxidise with exposure to air. This process produces a
mild acid solution (vinegar) which can attack fuel system fittings.
• Long term exposure to Ethanol damages some types of plastics. The J120-C details
replacement times for fuel lines which are designed with Ethanol fuel blends in mind,
however increased monitoring of fuel lines is recommended in an aircraft using Ethanol
blends.
• Some fuel testers (including the type supplied by Jabiru Aircraft at the time of writing) have
a scale on their side which allows the Ethanol content of a fuel to be checked & assessed.
Several CASA documents discuss Ethanol, and Jabiru Aircraft strongly recommend that owners
considering using an Ethanol fuel blend read and understand this information before using a fuel
of this type. The following CASA document is current at the time of writing:
• Airworthiness Bulletin AWB 2828-003003

8.2 OIL
8.2.1 Engine Oil Specification:
Jabiru Aircraft approves lubricating oils of any brand name conforming to specifications MIL-L6082 for straight mineral oil and MIL-L-22851 for ashless dispersant oil.
Straight mineral oil must be used during the first 50 hours of operation for new and overhauled
engines, or until the oil consumption has stabilised. After the first 50 hours it is recommended
that ashless dispersant oil be used.
8.2.2 Engine Oil Viscosity Grade:
The following chart is intended to assist in choosing the correct grade of oil and must be
considered as a guide only. Multiviscosity grades can also be used as indicated

Commercial: 55 35 80 100 120
8.3 BRAKES
The brakes of the J120-C use automotive brake fluid. Refer to the J120 Technical manual for
details of appropriate brake fluid specifications.
WARNING:
The JABIRU uses automotive brake fluid (DOT 3 or DOT 4). DO NOT use Aircraft hydraulic fluid
(mineral based) or damage to the brake system will result.
