Refer to figure.
The Charter flight log is filled out correctly by the pilot of a light twin-engined aeroplane. Calculate the average Groundspeed from TOC to TORDU and the ETA at RODRA.

  • A

    183 kt; 07:17

  • B

    171 kt; 07:05

  • C

    183 kt; 07:09

  • D

    171 kt; 07:08

Refer to figure.
The aircraft covered the flight leg fromTOC to TORDU in: 06:46 - 06:10 = 36 min.

So, its Average Actual Groundspeed will be: TOC - TORDU distance / TOC - TORDU time = (73 + 37 NM / 36 min) x 60 = 183 kt.

From TOC to RODRA, the altitude (FL090), TAS (190 kt), Track (047) and Heading (055) remain the same. The 1° increase in both track and heading at the last flight leg is negligible and will not alter the result significantly.

Thus, the flight time from TORDU to RODRA is: TORDU - RODRA distance / Actual GS = (71 NM / 183 kt) x 60 = 23 min.

Therefore, the ETA at RODRA will be: ATO TORDU + flight time from TORDU to RODRA = 06:46 + 23 = 07:09.
