Magnetic heading and course error on the flight plan (kneeboard)

[Tripack]

Hello,

I've noticed differences between the course and heading displayed on the flight plan and what is measured on the F10 map.

In the example below:

Start Point -> B1:
  Navplan: Course(T)= 286° - Heading (M) = 294°
  Map F10: Course(T)= 280° - Heading (M) = 287°

B1 -> B2:
  Navplan: Course(T)= 077° - Heading (M) = 084°
  Map F10: Course(T)= 071° - Heading (M) = 078°

B2 -> B3:
  Navplan: Course(T)= 355° - Heading (M) = 003°
  Map F10: Course(T)= 349° - Heading (M) = 356°

The difference is between 6 and 7°.
This corresponds to the magnetic declination, which is 6.7° on this part of the map.

On the Syria map, the difference is between 4° and 5° , the magnetic declination is 5°.
 

So there is a correlation with magnetic declination, which seems to be incorrectly taken into account.

Thanks
