1 GENERAL
The Aircraft Operating Instructions (AOI) has various sections to comply with the ASTM standard. The
General Aviation Manufacturers Association (GAMA) format has been adopted and used where
applicable for this weight shift controlled microlight.
The AOI contains information for the XT 912 base coupled with either the Streak 3 wing or the Cruze
wing. All relevant information is supplied for either configuration. The operator must ensure that the
correct data is referenced for the particular wing base combination.
1.1 Introduction
This Microlight series has been designed and manufactured in accordance with the ASTM designation
2317-04 Standard Specification for Design of Weight-Shift-Control Aircraft.
The aircraft has also been designed to the higher level of certification requirements for weight shift
controlled aircraft. The design standard of BCAR Section S, has been used for certification as a primary
category aircraft.
As an Australian Company, we are proud of our range of microlight aircraft. Our microlights have been
developed to provide the economy and durability required to meet the exacting demands of our
Australian conditions.
The success of our microlights is based upon a high standard of product quality, innovative design
engineering and exceptional standards of reliability and performance that have been established since
1983.
Regular maintenance is required to keep your microlight in a safe condition. Detailed maintenance
requirements are outlined in the Wing and Base maintenance manuals. Please reference these manuals
to ensure your microlight is maintained correctly.
In the USA, the FAA registers and administers Light Sport Aircraft.
The AirBorne Team has developed from the long-standing friendship of a group of enthusiasts who share
conviction in the intrinsic advantages of weight shift controlled aircraft. The AirBorne Team is confident
your new microlight will provide you with many years of enjoyable flying, and we wish you and your family
safe and happy flying for the future. The operating procedures outlined in this handbook are the result of
AirBorne’s knowledge and experience gained since 1983.
NOTE
AirBorne data packages will be revised from time to time. It is therefore important that owners promptly
notify Airborne of any changes to their contact details. Owners registered on AirBorne’s database will be
notified of any changes to data and directed to the AirBorne web site (http://www.airborne.com.au/) for
the applicable pages. The amended pages should be printed and the replacement pages inserted in the
folder as soon as possible. The amendment table should at that time be updated with the appropriate
details and date. Revised pages will be sent by mail if requested from AirBorne WindSports, the contact
details are at the front of this manual.

THAN THOSE, WHICH CANNOT BY LAW BE EXCLUDED.
THE SAFE OPERATION OF THIS AIRCRAFT RESTS WITH YOU, THE PILOT.
WE BELIEVE THAT IN ORDER TO FLY SAFELY YOU MUST MATURELY PRACTICE
AIRMANSHIP.
OPERATIONS OUTSIDE THE RECOMMENDED FLIGHT ENVELOPE SUCH AS AEROBATIC
MANOEUVRES OR ERRATIC PILOT TECHNIQUE MAY ULTIMATELY PRODUCE EQUIPMENT
FAILURE. YOU ARE REFERRED TO THE OPERATING LIMITATIONS IN SECTION 2 OF THIS
MANUAL
THE SETTING UP AND BREAKING DOWN OF A MICROLIGHT/ULTRALIGHT/TRIKE/POWERED
HANG GLIDER, TRANSPORTATION AND FLYING WILL HAVE AN EFFECT OVER TIME ON ITS
STRUCTURAL INTEGRITY.
THE AIRCRAFT WILL REQUIRE MAINTENANCE AS OUTLINED IN THE APPLICABLE
MAINTENANCE MANUALS.
LIKE ANY AIRCRAFT, SAFETY DEPENDS ON A COMBINATION OF CAREFUL MAINTENANCE
AND YOUR ABILITY TO FLY INTELLIGENTLY AND CONSERVATIVELY.
WE HOPE THAT YOUR AIRCRAFT WILL PROVIDE YOU WITH MANY HOURS OF SAFE AND
ENJOYABLE FLYING.
WARNING
OPERATING PROCEDURES, TECHNIQUES, ETC. WHICH IF NOT FOLLOWED CORRECTLY, MAY
RESULT IN PERSONAL INJURY OR DEATH.
CAUTION
OPERATING PROCEDURES, TECHNIQUES, ETC. WHICH IF NOT STRICTLY OBSERVED, MAY
RESULT IN DAMAGE TO THE AIRCRAFT OR ITS INSTALLED EQUIPMENT

Aircraft Operating Instructions Edge XT 912 Streak / Cruze GENERAL
February 2006
Issue 1.1 Page 6
1.1.5.1 Base
The XT 912 trike base is a two seat (in line) weight shift controlled aircraft. A Rotax 912 four-stroke
engine producing 80 HP powers the base. The layout is typical of this class of two seat trike design, with
the pilot passenger “pod” being suspended by a triangular frame, hinged from the mast head about the
pitch and roll axes, to provide for weight shift control.
The cockpit has a tall windscreen for improved wind deflection and is cut away at the sides to allow for
easier pilot access. The wide rear 6-inch wheels remain a feature of the XT base but the wheel
pants/spats have been redesigned and include integrated aerodynamic fins to improve base yaw stability.
1.1.5.2 Wing
The Streak 3 and Cruze wings are the result of continued refinement of AirBorne trike wings. The wings
are fairly typical of an established class of swept, tapered, flexible fabric wings with enclosed crossbars
and a relatively high aspect ratio.
Both the Streak and Cruze sail have several cloth and velcro shear ribs, which combined with an
excellent sail “fit”, produces a wing that has light handling with impressive “feel” in turbulence. The
battens ends are a unique design, which can be adjusted to vary tension for tuning the wing. The batten
mechanism allows easy installation and removal of the battens.
An airfoiled aluminium section is used for the down tubes and king post. Clever engineering features
fittings that look smart and are positioned to achieve minimum drag.
1.1.5.3 XT 912 Streak
The XT 912 combined with the Streak 3 wing has proven to be an excellent combination. The total fuel
capacity is 70 litres and combined with the Rotax 912 delivering a smooth 80 HP allows long cross-
country flights. The combination produces a very stable Microlight, which is perfectly suited to cross
country flying.
1.1.5.4 XT 912 Cruze
The Cruze wing was developed as an intermediate wing with lower stall speed and lower top speed.
Additional sail area has been added to the tip of the wing with a reduction in the sail luff curve. The result
of the XT 912 coupled with the Cruze is a very stable wing with a “softer” feel than that of the Streak
wing. The Cruze wing is a good all round wing with lower top speed than the Streak 3. The stall speed is
also lower with shorter take off and landing distance required.

1 Foot (ft) = 0.3048 Metre (m)
1 Statute mile = 1.609 Kilometres (km)
1 Nautical mile (NM) = 1.852 Kilometres (km)
1 Millibar (mb) = 1 Hectopascal (hPa)
1 Millibar (mb) = 0.1 Kilopascal (kPa)
1 Imperial gallon = 4.546 Litres (I)
1 US gallon = 3.785 Litres (I)
1 US quart = 0.946 Litre (I)
1 Cubic foot (ft3) = 28.317 Litres (I)
1 Degree Fahrenheit (F) = (1.8 X C)+32
