EHSI trainer

This app was primarily developed for aviation training purposes.
Mental calculation and visualization of VOR-radial interceptions can be practiced.

Type of interceptions:
90°/45° interception, if the required and the actual radial differs by 30° or more.
45° interception, if the difference is less than 30° but more than 15°.
Correction, if the difference is 15° or less.
(In case of correction, the interception angle is 2x the difference.)

By turning the hint ON, the initial and, if applicable, the second interception track can be seen.
The course selection can be done manually by touching and dragging the CRS dagger.

The instrument is designed based on Airbus's navigation display.
