As we were transiting the Lichfield RVC one evening, the ATCO asked what type of navigation system we used in the (pre-EGI) VC10K - it was in the time before the RVC was realigned with the Coningsby and Brawdy TACANs..

Navigation is now mostly done by multiple INS/GPS - but Garmin can't cook beef olives over ROZ2 as
Tengah Type could!
*In Tengah Type's case, quite a lot....
