  Certification

 

Under Construction..

Air Creation microlight light sport trikes - are certificated to several International NAA Design Standards. The certification compliance of microlights is an expensive procedure which confirms the structural, aerodynamic and operational integrity of the aircraft components to a recognised design standard for compliance acceptance.

DescriptionThe Air Creation philosophy of reliability, safety and simplicity is supported by the credentials of manufacturing in excess of five thousand aircraft and developing more than thirty nine different models, since 1982 and Model/Type Design Certification Compliance to all the major demanding certification microlight Design Standards  across the globe. The Direction Generale d'Aviation Civile (DGAC) issue the Fiche d'Indentification i.a.w. certificate upon approval of individual ULM aircraft under Law 16 - 1998, France. The DGAC and German - Deutscher Ultraleicht Flugverbande. V. (DULV) are International Aviation Administration organisations under the NAA and recognise Air Creation as a primary manufacturer of flexwing microlight aircraft.

What is Certification?

Basically, certification is the determination of the design safety of an aircraft and the production quality control of individual aircraft. There are many different structural, operational and load testing procedures conducted on individual components of an aircraft, to substantiate the absolute safety characteristics and parameters of the individual aircraft designs to a recognised Design Standard.

DescriptionSafety is never expensive, try paying for an accident.‚Ä®Certification compliance is a complex task, many pilots may not appreciate the commitment of a manufacturer to achieve certification for their products. Certain flexwing microlights we can fly today are very safe and have proven structural and aerodynamic integrity that provide you with  absolute in-flight safety.

A major concern for all flexwing pilots is the pitch stability of the wing a delta flexwing has no tail and requires positive pitch stability to prevent tumbling (end over end flipping moment in the vertical axis) especially in extreme violent turbulence or mid air collision, which maybe encountered during any flight.

Absolute in-flight safety

The Air Creation wings have German DULV Pitch Test Certificates to confirm the stability of the wing in the pitching axis. If you have ever flown a pitch unstable flexwing you will find the flight controls become unpredictable, you have loss of control pressures and you are unable to accurately maintain your flight path.  Very dangerous and absolutely unacceptable.

The German DULV Pitch Test Vehicle  is designed with a mast head where the wing is attached, and the test rig has hydraulic rams to alter the wing angle of attack during the test procedure. The vehicle is driven at nominated speeds on a large runway with testing officers recording the test wings pitch characteristics, lift co-efficients and other data, on high technology video computer recording equipment.

The Test Wing is driven forward (at angles of attack outside the normal flight envelope) which tests the pitch stability characteristics in the positive attitude.. and also in a backward motion on the vehicle testing the reflex bridle / twist systems for failure or compliance. Once you have witnessed flexwing pitch testing, you will never fly a flexwing not tested to the German DULV Pitch Test Requirements or any approved method of pitch test.

Since about 1990  in Australia and around the globe.. it has been a requirement of hang glider manufacturers to have their production gliders  Pitch Test Certificated to either the German or American Standards.

How do you know if your flexwing microlight wing is really pitch stable in turbulence?

The tricycle undercarriage has a numerous amount of certification testing procedures; from engine deceleration  forward / sidewards, occupant seating strength, fuel tank loading and many other structural limit and maximum design tests. Stability on the ground and resistance to roll over accidents is ensured with Air Creation aircraft, with low centre of gravity, wide wheel track and a positive steering geometry. Safety in the event of a hard landing is ensured with deep travel energy absorbing suspension and landing gear. The structure of the trikes have design characteristics with high property yields to absorb energy with progressive 'crumple zone' failure, offering the best protection to the occupants.

The German Design Standard requires for four point occupant harness, which provides exceptional safety with retractable comfort in freedom of movement for both pilot and passenger. The main pylon and front support have internal cables. The wing/trike connection is fitted with a safety strap which has a secondary function looping around the cross bar restraint cable. These methods of backup safety maintain the aircraft's primary structural components in the unlikely event of mid air collision or loss of control scenarios in extreme flight conditions.

The integrity of an aircraft

Certification is expensive. Justify + Quantify + Verify = the real integrity of an aircraft.
All Air Creation flexwing microlights are subject to an extended flight test program beyond the Australian and UK Section S airworthiness approval, including extreme high speed down wing (@ MTOW) landings, deliberate hard 'crash landings' under emergency parachute, and extreme altitude (13,000 ft AMSL) regular snow operations (30 knot downwind - downhill) take offs.

Certification of sport aircraft - is basically a formal acceptance method or practice, attesting the design complies with a recognised standard for flight safety different design standards require different testing procedures.  Air Creation flexwing microlights have major certification in five countries and compliance acceptance in over forty countries worldwide the toughest flexwing microlight Design Standards require aerodynamic pitch testing.  Why risk your Safety flying anything less.
