Topic asymmetric collaps with DHV 1 und 1-2 gliders:

DHV safety manager  Karl Slezak shows a video from test flights of the DHV test pilots with different collapse variants “. The footage clearly shows that the additional collapse variant 60° relative to the longitudinal axis and 60% wingspan which was proposed at the manufacturer hearing on the 18.07.07 is realistic. The more dynamic gliders which are noticeable in practical flight will be separated from the less dynamic ones.

The DHV has informed all manufacturers about the results of their gliders when they have been in the research testing.

Topic asymmetric collaps with DHV 2 gliders:

Kari Eisenhut disbelieve that Kat 2 gliders would handle the proposed collapse variant without worsening their category . He suggests to leave away the variant  75% collapse with higher kink angle. The DHV agrees to abandon the variant  75% collapse with higher kink angle, because the knowledge of the 60% collapse is already sufficient.

Summarisation asymmetric collapse 

All manoeuvre have to be flown non accelerated as well as accelerated 

DHV 2-3 and 3

60% wingspan, 45° relative to the longitudinal axis 
75% wingspan, 45° relative to the longitudinal axis 

DHV 2

60% wingspan, 45° relative to the longitudinal axis or higher, depending on gliders behaviour
75% wingspan, 45° relative to the longitudinal axis  

DHV 1 und 1-2

60% wingspan,  45° relative to the longitudinal axis or higher, depending on gliders behaviour
60% wingspan, 60° relative to the longitudinal axis  
75% wingspan, 60° relative to the longitudinal axis or higher, depending on gliders behaviour

Topic steep spiral 

The by Karl Slezak proposed additional test manoeuvre steep spiral „initiated according to doctrin„ is  supported. A more precise definition of easy recovery and demanding recovery has to be found. The DHV will do this and give the following proposal in advance.

Easy recovery  >> Light brakes and/or weight shift 

Demanding recovery >> when the criteria for easy recovery are not met.
