Quiz: What Altitude Are You Cleared To?

Boldmethod

How high (or low) should you go?


  1. 1) You're approaching Hartsfield-Jackson Atlanta Int'l airport in your Gulfstream G650. ATC says "Gulfstream 878NE, cleared for the BNELE One Arrival via the Nashville transition (BNA), descend and maintain FL180."

    As you cross GRNDY you...

    Because you were not cleared to "descend via" the BNELE One Arrival, you must maintain FL180 until given further instructions. However, you are still required to maintain lateral navigation.

  2. 2) You are on the ground in your Pilatus PC-12 at San Fransisco Int'l airport. ATC says "Pilatus 253NB, cleared to the Seattle-Tacoma airport via the AFIVA ONE departure, then as filed. Climb via the AFIVA ONE departure. Departure frequency 120.9, squawk 3545."

    You filed FL210. How high can you climb until further instructions from ATC are given to you?
    View AFIVA One Departure

    Because the top altitude is 10,000' for the AFIVA one departure, this is as high as you can climb until ATC permits you to climb to your filed altitude.

    Because the top altitude is 10,000' for the AFIVA one departure, this is as high as you can climb until ATC permits you to climb to your filed altitude.

  3. 3) You are in your DME equipped Piper Seminole shooting the Localizer 12L approach into Minneapolis-St.Paul Int'l. You have been vectored onto the approach in between the HAMML and WASHY intersections. ATC says "Seminole 434NR, turn right heading 090, maintain 3,000' until established, cleared Localizer 12L approach."

    What is the minimum altitude you are permitted to descend on the approach without having the the runway environment or red side row bars in sight?

    Because you can identify AASUN, the furthest you may descend is the MDA for the approach, which is 1240' MSL.

  4. 4) On the Canoga One departure, what does the 1700' altitude by the blue arrow mean?

    This is a maximum altitude. If you're flying the Canoga One departure, you can't go higher than 1700' until you've crossed 2.2 DME south of VNY.

  5. 5) What is this listed altitude?
    stem-5-v2 Boldmethod

    This is the Maximum Authorized Altitude (MAA) which according to the FAA is the "highest altitude on a Federal airway, jet route, RNAV low or high route, or other direct route for which an MEA is designated at which adequate reception of navigation signals is assured". MAAs can also be used when routes need to be top-altitude restricted for traffic flow above them.

  6. 6) What does the altitude 7000' at WDLNS indicate?

    This indicates that 7000' is a mandatory altitude you need to be at when crossing WDLNS.

Well, that was a tough quiz...

You scored %. But look on the bright side: you just learned a lot about clearances and altitude restrictions...
