Q
How to calculate track error in degrees?
A
Track error = Miles off track x 60 / miles flown
2
Q
How to calculate the correction angle
A
miles off track x 60 / miles to go
3
Q
If we have an angle of a triangle and the value of one side, how to calculate?
Angle = 6.5
Adjacent = 35
A
For this we need to use TOA
X over 35 = TAN 6.5
=
(TAN 6.5) x 35 = X
X = 3.98NM
4
Q
How to calculate distance to VOR
A
(GS x time) / Radials crossed
5
Q
How to solve a right triangle sides?
A
pythagoras SohCahToa
or
A squared + B squared = C squared
6
Q
How to solve non-right triangles?
A
Use the law of sines/Law of cosines =
Sin A / a = Sin B / b = Sin C / c
