Note: This question is very similar to 615959 but the times have been changed slightly in the annex.

Most of the flight log shown uses planned data. The GS column is calculated from the planned winds, and the ETAs are written based on a known departure time and the planned leg times. However, the real conditions during the flight will of course be slightly different to the planned conditions.

The ground distances between points are shown on the log, as are the actual times of arrival over the waypoints (ATO). We can use these times to calculate our actual inflight groundspeeds as follows:

• TOC → SOPET: we flew 73 NM in 06.10 - 06.33 = 23 mins ⇒ GS = 73 / (23/60) = 190 kt
• SOPET → TORDU: the leg is 37 NM and took 06.45 - 06.33 = 12 mins ⇒ GS = 37 / (12/60) = 185 kt

We are asked about our GS at TORDU, so don't need to calculate the GS from TOC to SOPET. It is shown as an example, and in other questions this may be necessary.

The distance from TORDU to RODRA is found by adding the remaining leg distances:

• 26 + 14 + 14 + 17 = 71 NM

Flying 71 NM at a GS of 185 kt will take:

• 71/185 = 0.384 hrs = 23 mins

We will arrive at RODRA 23 mins after TORDU:

• 06:45 + 0:23 = 07:08
