GENERAL NOTES ON THE MOUNTAIN GOAT TANDEM BUSHPLANE

L. A. Fox / FAA DER Flight Test Pilot

  1. Familiarization in the Mountain Goat, tandem, bushplane was conducted in the vicinity of Palmer, AK, in April, 2005, and included 3 flights at mid to light weight and mid to forward cg of the proposed envelope.
  2. The technique used to calibrate airspeed indications was valid, although documentation on the equipment used to calibrate was not verified. A qualitative assessment of speeds attained in flight, however, revealed a stall in the vicinity of 30 mph and a cruise speed of over 150 mph. These estimates were conservative and reveal a maximum to minimum ratio of over 5 to 1. Verifiable instrumentation may, in fact, demonstrate a ratio closer to 6 to 1.
  3. Level flight stall characteristics at the weight and CG tested were docile and totally certifiable.
  4. Directional stability at slow speeds was very positive.
  5. Roll control throughout the speed range tested was good.
  6. Landing on and takeoff from a gravel bar with small boulders was comfortable and controllable.
  7. The engine / fixed-pitch prop combination produced a healthy balance between cruise and climb.
