A Pilot is planning a VFR flight from Salzburg (LOWS) to Linz (LOWL). If the variation is 003°E, and the aircraft flies a direct track with a groundspeed of 120 kts, what is the flight time?

  • A

    1 hour 58 minutes

  • B

    18 minutes 13 seconds

  • C

    2 hours 12 minutes

  • D

    27 minutes 15 seconds

Refer to figure.
Firstly, locate the two airports and draw a straight line (direct track) connecting them.

For the chart given, the scale is not known, thus, a plotter cannot be used to determine the distance. In the case where the scale is not given, or you are unsure of the scale, transfer the line between the two points along a meridian.

It is known that, along a meridian: 1' = 1 NM. The straight line, if transferred along a meridian, it will be 54.5', so 54.5 NM.

The flight time is given by the formula:

  • Flight time = Distance / Groundspeed
  • Flight time = 54.5 NM / 120 kt
  • Flight time = 0.454 hr or 27.24 min or 27 min 15 sec
