Radar SEP Practice Test

When VFR aircraft are switching from IFR, the appropriate action is to continue squawking the IFR code until they are instructed otherwise by Air Traffic Control (ATC). This ensures that ATC can maintain radar contact and situational awareness of the aircraft during the transition. Immediate squawking of 1200, which is the common VFR code, may lead to a loss of communication and tracking by ATC, especially if the aircraft is still within controlled airspace or receiving services. Therefore, it's important for pilots to follow ATC instructions regarding transponder codes until they receive clear directives on when to make the switch. This helps to ensure safety and proper coordination, especially in busy airspaces.
