Touring Motorgliders: Versatility in Action

  1. 1. • Presenters: – Richard Pearl, CFIG – Michael Haisten, A&P/IA• What is a TMG?• Legal Issues• The Fleet• Geography• Mechanical Issues• What’s new with the TMGA?
  2. 2. What is a TMG YES Close, but No
  3. 3. Why TMGs:• Combine soaring and travel• Fly even when soaring not an option• Forget the tow-plane• Carry passengers (most TMGs)• Fly further; no land outs or retrieves• Medical self-certification
  4. 4. TMG IssuesLegal: • It’s a Glider, so you need a GLIDER rating • AC 61-94 –With a power rating (ground instruction, 3 flights) –Without a power rating (5 hours in TMGs, dual X-C, 10 T.O./Landings; need lots more……….
  5. 5. TMG Issues (cont’d Additional training; endorsement required – Airspace, communications, weath er Additional complexity – engines, equipment Storage: tie-down or hangar
  6. 6. Classic TMGs (< 1980) Fournier RF4DSuper Falke Fournier RF5D Eisenbahn-Fliegen
  7. 7. Classic TMGs (cont’d)ASK 14 Ryson Schibe 34 MotorFalke
  8. 8. Early Modern (1980 ‘s)Grob 109 BlanikVivatHK Dimona Europa
  9. 9. Early Modern (cont’d)Lark (IS28) Caproni Strojnik Ogar
  10. 10. Early Modern (1980 ‘s)HB-23-2400 TaifunSGM 2-37
  11. 11. Middle Modern (1990’s) Stemme Ximango Diamond Extreme
  12. 12. Modern - 2000Lambada Pipistral VirusCarat Pipistral Taurus
  13. 13. Modern (cont’d) SambaPhoenix TST BonusJet
  14. 14. Mechanical Issues TMGs are more a single engine land plane than a glider. – Additional systems include: – Engine – Fuel systems – Propeller / Propeller control – More complex electrical systems – Navigation systems
  15. 15. TMG - Common engines Limbach – Grob – Sachs These are VW derivatives 80 to 90 HP Heat sensitive Lower cost ****not built from VW parts from the auto parts store**** RotaxPurpose-built aircraft engine 80-100-115 HP More complex with liquid cooling 115 HP is Turbo charged Higher cost
  16. 16. Propellers – Fixed Pitch  Simple construction  Low cost  High drag in “glider mode”  Air starts possible
  17. 17. Propellers – Variable Pitch  Many parts: Manual, Hydraulic, or Electric control  Climb or Cruise pitch available  Featherablefor reduced drag in “glider mode”  Air starts possible…..maybe
  18. 18. Propellers – FoldingFixed pitch Very low drag in “glider mode” Air starts not possible
  19. 19. Other Considerations Glider category VS LSA (Light Sport Aircraft) Gliders have gone through the FAA certification process Annual inspections by an A&P with InspectionAuthorizationRotax can only be maintained by a Rotax trained mechanic LSA has lesser certification requirements for the aircraft LSA requires a higher level of maintenance All Manufacturers maintenance schedule MUST befollowedRotax can only be maintained by a Rotax trained mechanic
  20. 20. Added Complexity Fuel systems Fuel tanks, lines and valves Fuel pumps Electrical systems Charging systems Lighting Navigation systems TMG’s tour so they commonly have aircraft navigation systems VOR Receivers DMEs GPS Some even full IFR equipped
  21. 21. What’s new with the TMGA?• Touring Motor Glider Association Web Site: www.touringmotorgliders.org
  22. 22. TMGA: Where do we go from here? • TMGA Seeking formal SSA Division Status • Fly-Ins and informal meets • Fun contests (soaring & fuel efficiency) • International participation
