Possibilities of high altitude flutter during wave flights

Full text not available from this repository.


The question of what maximum speed to fly in order to prevent high altitude flutter has been a hot subject of discussion among experienced wave flyers for a long time. It is not trivial because a bailout at altitudes with outside temperature of -70°C is a considerable hazard in itself. The question is: does the red-line airspeed apply to indicated airspeed (IAS) or to true airspeed (TAS) as far as flutter at high altitude is concerned? Or is there an in-between limit?
