Hi again Bobby,
Remind them that FR24 is NOT real time! It is subject to collection, decoding and transmission delays, gaps in their receiver network and the vagaries of internet accessibility. OK, usually only minor delays, but I have seen some significant 'gaps' and variations in aircraft position which would certainly not be acceptable for collision avoidance and the unreliability of internet connection in the air might prove a bit interesting too! What you are showing them is 'LIVE - DIRECT FROM THE AIRCRAFT ITSELF' and not affected by anything outside your control. And all for the measly sum of £200. That usually works.
Regards
Peter
