Under this topic will be posted basic rules of thumb.

[admin]

1 NM displacement per 60 NM enroute = 1 degree off-course.

a/60 = B/C

a = degrees of displacement
B = Distance off-course
C = Distance Enroute

Code: Select all

   |\
   | \
   |a° \   
C  |    \
   |     \
   |_____ \
       B


Example:
A plane flies from point 1 to point 2 after 45 NM enroute the pilot recognise that he drifted 5 NM to the right of the course. what is the drift angle?
Answer:
a=?
B=5
C=45
a/60=5/45
45a=300
a=6.6°

ok, this is a real basic one...

Code: Select all

MB=MH+RB

MB=magnetic Bearing
MH=Magnetic Heading
RB=Relative Bearing

Magnetic Compass

Mag Compass Errors: DVMONA
D - Deviation
V - Variation
M - Magnetic dip
O - Oscillation
N - North/South turning error (UNOS or ONUS)
A - Acceleration(ANDS or DNAS)

North South turning error (North Hemisphere: UNOS; South Hemisphere ONUS):
UNOS- Undershoot North; Overshoot South.

Acceleration error (North Hemisphere:ANDS; South Hemisphere DNAS):
ANDS - Accelerate North decelerate South
