Launching Without Control

Unless there is a departure procedure (DP) or obstacle departure procedure (ODP), pilots departing from an airport located in Class G airspace are on their own for navigation. But then, unless the clearance includes a departure procedure, pilots are always responsible for their navigation from the pavement into the en route structure until they are radar identified and on an active vector. Take it from us, if there is a DP, especially an ODP, use it. ODPs exist because there are hard objects somewhere in your potential departure path.

Key Takeaways:

• Pilots are responsible for their navigation and obstacle clearance from departure until radar identified and on an active vector, even if an ATC heading is given; Obstacle Departure Procedures (ODPs) are critical for safety and take precedence.
• A clearance is required to enter controlled airspace in instrument conditions, ideally obtained on the ground from ATC or Flight Service, which will be phrased differently depending on the source.
• Pilots must maintain their own terrain and obstacle clearance until reaching controlled airspace, even when asked by ATC due to Minimum Vectoring Altitude (MVA) issues, and can proactively volunteer this capability.
