Question with the CRP-5 Windarm edition
Hello, again dear pilots, I finally got my PPL and have a lot of hours to fly out alone, and I am about to put my full focus on ATPL. The first subjects I want to pass are Navigation, meteorology and Human performance.
I have a question about the CRP-5 Wind-arm edition that i can't find anywhere on the internet. I bought the wind-arm edition, because it is better for me, and it does not get so much weared, when you write on it and delete it with your eraser all the time.
The problem is that the ATPL books only explain using the CRP 5 without the wind-arm. I can 90% of the things on it, but there is one thing i never found out.
It is when you for example have a task like this one:
TH: 100 degrees
Wind speed: 30 kt
Wind direction: 170 degrees
TAS: 150 kt
How can I find the true track, giving this information? WIth CRP-5 Wind-Arm.
I have pounded my head on it for hours and failed every time and I tried youtube etc, but can't find it anywhere.
Thanks in advance.
