Hello everyone,

Just wondering if anyone can provide an explanation for this question from the CMET practice exams?



The correct answer is: light headwinds throughout the flight

There wasn't an explanation in the comments so any insights would be appreciated!

I am no expert and there might be a difference between the versions of our book, but (??? assuming Part 8 - Revision Test - question 10 ???)
. then Flying A to B means heading NORTH WEST ... or about 315 degrees-ish ...
. My questions says you're flying at 6,500 FEET ...
. On the GPWT that means you're reading for a value at/just_interpolated below the FOURTH row (in pink)

Meaning, I think I'm flying through the following boxes:
. 220 degrees at 5 knots
. 340 degrees at 9 knots
. 340 degrees at 6 knots
. 000 degrees at 14 knots
. 300 degrees at 8 knots
. 280 degrees at 8 knots
Remembering GPWT is written degrees TRUE (not) MAGNETIC !
(if that even changes the answer)

So, If I'm flying pointing the nose of the plane NW/315degrees,
and the WINDS are coming from 280-340ish degrees, AND
wind SPEED is between 5 & 9 knots (ignoring out 14kt outlier) which is "MODERATE" (imho)
Then:

..., my answer ... is "light to moderate headwinds throughout the flight".



Hope that helps. Cheers, Tim.
