I would support this 100%:
Zitat Mitarbeiter Flugsicherung (anonym) ATC can only know what a pilot tells us. If the captain feels the weather ahead poses such a significant threat to his/her aircraft, he/she should have say in the first transmission “need immediate left turn 120 degrees and climb to FL380 due weather”. If the ATC response was not to their satisfaction, say the magic words and do it anyway. If you are in conflict with another aircraft, it’s my job to get it out of your way in those situations. You are my number 1 priority and nobody is getting in your way.
Zitat Pilot (anonym) Here’s one solution to the “Hazardous/insurmountable cloudbank problem” which we all know, from most recent experience, is acceptable to the commercial aviation establishment – holding patterns.
See an impenetrable, potentially hazardous cloud system directly in your path, then adopt a holding pattern en-route till it thins or moves on. A new IATA protocol to facilitate this ?
And as for the weather radar definition problem, what’s preventing aircraft in a locality exchanging weather radar data over a local airbourne data mesh network to form a composite 360 degree view. After all, the military do this with tactical info for fighting aircraft e.g. Swedish Grippen.
