Quiz: Can You Answer These 7 IFR Departure Questions?

Can you answer these departure questions? It's time to find out!


  1. 1) You're sitting on the ramp and ATC gives you an IFR clearance with 'hold for release' instructions. Are you allowed to takeoff at this point?

    If you have a hold for release time, you can't depart IFR until that time. You can, however, cancel IFR, squawk 1200, and takeoff VFR (assuming weather conditions allow). Keep in mind if you takeoff VFR, you may not be able to get an IFR clearance while airborne.

  2. 2) The next day you're flying out of a non-towered airport. You get an IFR clearance with a clearance void time of 2245Z. What needs to happen by 2245Z?

    You need to be airborne by 2245Z. Additionally, failure to contact ATC within 30 minutes of your clearance void time results in your aircraft being considered overdue, and search and rescue operations will be started.

  3. 3) You're departing an airport IFR. What is the minimum climb gradient you need to maintain, unless it's otherwise specified?

    Unless otherwise noted, required obstacle clearance for all departures is based on the pilot crossing the departure end of the runway at least 35 feet above the departure end of runway elevation, climbing to 400 feet above the departure end of runway elevation before making the initial turn, and maintaining a minimum climb gradient of 200 feet per nautical mile (FPNM), unless required to level off by a crossing restriction, until the minimum IFR altitude.

  4. 4) You're departing runway 24 at Salida, CO and flying the RONBE ONE departure. What is the minimum climb gradient you need to maintain initially after takeoff?
