IFATCA Policy is:

Electronic filing and automated conformance checking of flight plans are preferred.

Air traffic controllers shall be able to issue any clearance to an aircraft based on the capabilities in its flight plan. Automation should be in place to detect if, according to flight plan information, an aircraft is unable to execute any procedure in use.

Flight plan submission and correction by controllers, while responsible for separation of aircraft should be minimized.

ATCOs shall be presented with flight plans in a single flight plan format.

ATCOs shall not be responsible to maintain multiple versions/formats of the same flight plan.

ATCOs shall not be responsible to translate flight plans into alternative flight plan formats.
