Final answer:
Yes, it is possible to depart VFR after filing an IFR flight plan and pick up your clearance in the air. This process is called an 'airborne clearance'.
Step-by-step explanation:
Yes, it is possible to depart VFR after filing an IFR flight plan and pick up your clearance in the air. This process is called an 'airborne clearance' and it is commonly used by pilots to save time and avoid ground delays. To do this, the pilot must be in communication with air traffic control (ATC) and receive their clearance before entering controlled airspace.
Essentially, the pilot would depart VFR and then contact ATC to request their IFR clearance. ATC will provide the necessary instructions and route to follow. Once the pilot receives their clearance, they would transition from VFR to IFR and begin flying on their instrument flight plan.
It is important to note that pilots should only attempt an airborne clearance when they are confident in their ability to maintain separation from other aircraft and comply with all ATC instructions. Safety should always be the top priority.
