<!--  Hawker Sea Hawk yasim config.  This is a hack and not an
      authentic representation of the aircraft.  Having said

<!-- Approach configuration.
     I couldn't find any approach data but I think that the way
     the aircraft sits tail down on it's u/c indicates that it
     must land at a fairly shallow AoA to avoid hitting tail
     first.  The speed is a guess.

     I could see no sign or mention of spoilers or airbrakes in any
     of the docs or pictures I found.
