JOIN THE MARCO POLO ULTRALIGHT RALLY AND BECOME A PIONEER IN AVIATION  HISTORY

 

  UltraFlight Radio  

 

Qualifying Ultralight / Microlight Aircraft  

Classes: weightshift / 3 axis / single seat / 2 seat

Participating aircraft need to comply with the European Joint Aviation Authorities (JAA) / FAI definition (Section 10 of the FAI Sporting Code) of a microlight:

1.3 DEFINITION OF A MICROLIGHT AIRCRAFT

1.3.1 A one or two seat powered aircraft whose minimum speed at Maximum Take Off Weight (MTOW) is less than 65 km/h, and having a MTOW of:

  • 300 kg for a landplane flown solo

  • 330 kg for an amphibian or a pure seaplane flown solo;

  • 450 kg for a landplane flown with two persons

  • 495 kg for an amphibian or a pure seaplane flown with two persons

Note. These definitions also apply to foot-launched microlight aircraft and microlight aircraft with wings of a non-rigid structure.

1.4 TYPES OF MICROLIGHT AIRCRAFT

A microlight with movable aerodynamic control is a fixed wing aircraft with moveable aerodynamic surfaces for control.

  • A microlight with weight-shift control is a flexwing aircraft with pilot weightshift as primary method of control

  • A microlight with paraglider control is an aircraft which has a wing without any rigid structure and is controlled via movable aerodynamic surfaces and pilot weightshift

  • A microlight Landplane is an aircraft only capable of taking off and land on land, ice or snow

  • A microlight Seaplane is an aircraft only capable of taking off and land on water.

  • A microlight Amphibian is an aircraft capable of taking off and land on water and land.

  • A foot-launched microlight is an aircraft where the main undercarriage consists of the pilot and / or crews legs and is demonstrably capable of being foot-launched from level ground in nil or light wind.

Equipment Requirements

If this is going to be a Internationally Sanctioned Event, the FAI’s definition of qualified "Ultralights", "Microlights" and "VLA’s" (very light aircraft), is going to have to be trashed out and accepted before serious planning can get under way. Has such a craft been defined yet with certainty?

What max empty weight, max all up weight and max fuel capacity are my first questions. Starting from there other solutions can be worked out.

Here are some of my personal specifications of what I would call a doable craft:

  • In the engine department: RELIABILITY, RELIABILITY, RELIABILITY!
  • Two seats ( one to carry the gear, spares or fuel)
  • Steady min 60 kt TAS (mile a minute) at economy cruise power setting. Tails, you win heads you lose (the wind I mean). Expect a tail wind of 20+ kts in spring going east, at low level.
  • Min no wind range of 350 nm (650 km) to dry tanks
  • Wing loading to accommodate "continuous light to occasional moderate gusts"

What? Did you expect to fly only in the calm?

  • Basic pressure instrumentation for VFR flight, one gyro instrument for emergency IF.
  • Navigation gear: GPS, SATCOM phone. (Don’t forget the whiskey compass!)
  • Communication gear: two VHF radio coms min. Forget about requiring HF.
  • Lots of spare batteries: sponsors to provide free supply!
  • Transponder if it can be accommodated in the craft.
  • ELB and survival gear for all types of terrain.

Weight, Weight, Weight, what shall we do to meet those pesky requirements.
