My contact within SITA Flight Ops tell me that there could be a couple of positions in the Nav Dept based near LHR.
If you are interested send me a PM and I will get a contact name and number for you.
FYI SITA are a Flight Planning Provider for over 270 airlines world wide and are always looking for good aviation (Civil or Mil) backgrounds. Check out
