Flat spin
Either lost an engine or stalled one wing, coming in too slow in the pattern. The inboard wing, in a turn, losing too much speed and no longer generating lift.
Very difficult to recover as it often happens at low altitudes and it would require dropping the nose to regain lift on both wings.
Low altitude and one engine out is a very bad situation in a stall.
Is 17,000 a low altitude? I believe that is what is reported. I don’t have a clue. It sounds like you know about aviation. I just know from the movies it’s called a “flat spin”. I don’t know if that’s right.
Could you say a bit more?
DETECTION
Visual cue identifying severe icing is characterized by ice covering all or a substantial part of the unheated portion of either side window and/or Unexpected decrease in speed or rate of climb and/or
The following secondary indications:
• Water splashing and streaming on the windshield
• Unusually extensive ice accreted on the airframe in areas not normally observed to collect ice
• Accumulation of ice on the lower surface of the wing aft of the protected areas
• Accumulation of ice on propeller spinner farther aft than normally observed
The following weather conditions may be conducive to severe in-flight icing:
• Visible rain at temperatures close to 0°C ambient air temperature (SAT)
• Droplets that splash or splatter on impact at temperatures close to 0°C ambient air temperature (SAT).
THIS IS PRELIMINARY INFO, SUBJECT TO CHANGE, AND MIGHT CONTAIN ERRORS
Even more difficult in a multi engine aircraft. Have more physical forces to manage, feathering dead prop, etc.
The spin started at 17,000 ft.
Possible icing leading to a stall. Dew point and temperature were within 2 degrees C. It’s winter there. Twin engine turboprop stalls are very hard to recover from. Not enough rudder authority to counter act the rotation of the flat spin.
