How does a pilot obtain an IFR clearance?

A pilot obtains an IFR clearance by contacting Air Traffic Control (ATC) before entering controlled airspace under IFR. This process is essential for ensuring that the pilot is clear to operate under instrument flight rules, as it allows ATC to provide instructions related to the aircraft's route, altitude, and any necessary separation from other air traffic.

When a pilot intends to fly in IFR conditions, it is crucial to communicate directly with ATC for clearance. This ensures not only safety but also regulatory compliance. It is during this communication that the pilot receives specific routing information and altitude assignments, which are vital for safely navigating the NAS.

Filing a flight plan with the FAA is an important step in the overall process of flying under IFR, but it does not guarantee a clearance. The flight plan is often submitted in advance, but the actual clearance comes from the ATC communication, which typically occurs shortly before the flight begins or when entering controlled airspace.

Proficiency in a simulator is part of a pilot's training and certification process but does not directly relate to obtaining an IFR clearance. It prepares the pilot for IFR flight but is not a method for receiving clearance.

Submitting an online request may be a modern convenience for certain flight planning aspects, but it does not fulfill
