Ever stopped to think why there is a LOA?
Sure, the explanation i got was something about politics between different radar sectors regardless of actual conditions.
Ever had a good TCAS explanation?
Had 1 TCAS RA event in the last 2 years when someone was climbing like a rocket below me, who knows maybe he was given some frenchy clearance to reach a level "in 3 minutes maximum"
Did it ever occur to you that ATCo's aren't providing a service to individual pilots, but to Airlines?
Lately, in some countries, it seems they are providing a service solely to themselves.
