The correct answer is it depends on where the aircraft is registered. The basic aircraft will permit lift dump selection in the air provided the flaps are down, airbrakes are extended and the pilot has been dumb enough to lift up the dump lever and pull it back. It was determined on the original certification that the design was sufficient to prevent inadvertent (but not intentional) selection of lift dump.
If the aircraft is registered in Canada and I believe some other countries they require a weight on wheels interlock that baulks the lift dump selection until the aircraft is on the ground. I don't believe that modification is approved in other countries but it does require a separate flight manual supplement due to the necessary preflight checks and pre-landing checks of the system to ensure reliability of the baulk that it does disengage when required.
Hope this answers your question.

Not sure what a liftdump is, but here is a link to specifications and performance of a Hawker 800xp: http://www.jets.com/Hawker_800XP_jet_profile.aspx
