I am not a pilot, my understanding about flight is limited. EASA CPDLC will require airplanes to be capable of PM-CPDLC data communication to fly above FL285.
For an airline with multiple 767-300 &and 757-200 airplanes, would it be feasible to consider the option of flying BELOWbelow FL285 in the European airspace, instead of ceasing operation in the region or investing multi millionmillions of dollars for Avionics upgradeavionics upgrades?
Thank you in advance.
