Hi again

I might be going a bit mad but when I line up +30deg with 4000ft PA with a CAS of 100 on the old CRP-5, I get a TAS of 111, not 109 as is in the answer. As this question then wants you to find out the ground distance covered this speed is essential to get right. On my whizz wheel, to get 109kts the temp has to be 20deg at 4000ft.

Sorry to make a fuss over 2kts 😂
