The answer is 109nm, have seen the question in a book.
but don't know how they got 109nm
if someone could please elaborate.
Thanks!
the airway width is 5 nm from center line .therefore at 5.5deg distance is = 5NM/Tan(5.50) = 51.92 NM the error is either + or - so 51.92x2= 103.85NM closest answer is 109NM.
