12 / 20

When you leave the departure aerodrome overhead at 0815, you cover 8.5 NM in the first 5 minutes of flight. If the distance still to run to destination is 25.6 NM, what is your estimated time of arrival?

  • A

    0830

  • B

    0832

  • C

    0833

  • D

    0835

Let's solve this one:

  • From 0815 to 0820, you cover 8.5 NM in 5 minutes:
    Groundspeed = (8.5 ÷5) x 60 = 102 kt (approx.)

  • Remaining distance = 25.6 NM
    Time to go = (25.6 ÷ 102) x 60 = 15 minutes

  • Add 15 minutes to 0820 → 0835.
