Which aviation communication protocol allows pilots to file their flight intentions electronically?

The aviation communication protocol that allows pilots to file their flight intentions electronically is the flight plan. Filing a flight plan is a crucial step in flight operations, as it provides Air Traffic Control (ATC) with essential information regarding a pilot's intended route, altitudes, and timing. This electronic submission can typically be done through various online systems or apps, enabling pilots to streamline the process of notifying ATC of their intended flight path.

When pilots file a flight plan electronically, they ensure that the necessary information is automatically relayed to ATC, which helps with the overall management of air traffic and enhances safety. This process allows for more efficient traffic flow and helps ATC prepare for the flights that will be taking off and in the air.

In contrast, NOTAMs (Notices to Airmen) provide vital information regarding the status of navigational aids or any hazards along the flight route, but they do not facilitate the filing of flight intentions. ATIS (Automatic Terminal Information Service) broadcasts pre-recorded information about weather and airport conditions, which is important for pilots but not related to filing their flight plans. Clearance delivery is a service provided by ATC that informs pilots of their granted clearance to taxi and take off, but it is not a method
