BIK 116/8 for info on what is being done in Europe on CPLDC go to
www.eurocontrol.int and search for DALI
After you've read that lot come back and tell us we're reinventing the wheel.
EGPF Ffyer the French pilot was talking merde. The National Authority lays down which languages can be used where. Normally to be found in the AIP.
At one time Belgium still insisted that Maastricht UAC used French as well as English in the Brussels sectors. This despite no requirement for the controller to have French as a language.
Many states (inc. Germany still?) have frequencies allocated to their own language, normally only for VFR.
Five official languages (plua American) It doesn't require fluency, but just understanding the words, climb, descend and turn, may be enough to save your life.
For many reasons,with 4-3-3 on TCAS. Unfortunately it does not provide situational awareness but seems to be encouraging the opposite.
Take as an example a reporting point where 3 inbound routes converge for Amsterdam, EEL. Take an inbound flight descending to fl260 to cross EEL at level. After the usual, do we have to start down now, do we have to be level at EEL (Really, it's on the tape)
descent commences 4.500 to 5000 fpm. Passing FL265 the aircraft levels off then starts to climb and turn !!! Reason TCAS alert on traffic maintaining FL250. Pilot starts to bad mouth ATC.
Unfortunately this is happening more and more, together with questioning of instruction to turn,: traffic info then given response is ,"We see him on TCAS"
Lon More. more than just an Atco
