Quiz: Are You Ready For An IFR Departure?

Are you ready to fly an IFR departure?


  1. 1) You pick up an IFR clearance in your Gulfstream at a non-towered airport, with a clearance void time of 1735Z. What needs to happen by 1735Z?

    You need to be airborne by 1735Z. 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.

  2. 2) You're on the ramp in your Citation X, and you receive an IFR clearance with 'hold for release' instructions. Are you allowed to take off 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.

  3. 3) What is the minimum climb gradient for all IFR departures, unless otherwise specified?

    Unless specified otherwise, 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 Eagle County Airport. You plan to use runway 7 and fly the Gypsum Five Departure, which requires a minimum climb gradient of 580 feet per nautical mile to 12,000'. If your climb groundspeed is 90 knots, what is the minimum climb rate you need to maintain to 12,000'?

    At 90 knots groundspeed, you are traveling 1.5 nautical miles every minute. If you multiply 580 FPNM x 1.5 nm per minute, you get a climb rate of 870 feet per minute.

  5. 5) You're continuing on the Gypsum Five Departure from runway 7, you've just crossed the VAILE intersection, and you're turning left toward the Kremmling VOR. How many miles is it to Kremmling?

    You got it. The published distance from VAILE to the Kremmling VOR is 23 miles, and it's displayed in parentheses under the course line.

  6. 6) You lose communication on the Aspen Seven Departure and follow the lost comm instructions to turn left 273 degrees, intercept the I-PKN localizer back course, and proceed to LINDZ. When you intercept the back course, will you have normal or reverse sensing (assuming you're using a CDI with OBS)?

    Since you're flying outbound on the back course and using a CDI with OBS, you'll have normal sensing. The note on the bottom of the departure chart states that there is normal sensing as well.

Well, that was tough...

Nice work, you've got most of these departures down.
