Classic PET .... LEMALLIN is
absolutely right, for some of these PET/PSR questions VERY accurate wiz wheel
work is required ....
I get O=104 kts, H=123.5kts ....... which gives an
answer of 97.7nm
Be careful - these are 4 point questions
.... or 5% of the Exam!
Final thought - the best way to mark the wind is with
a FINE soluble felt tip pen - you get a very accurate 'dot' for the wind ....
