Landing mode

Open colingeniet opened this issue 4 years ago • 0 comments

Missing features of landing mode:

  • [ ] AJS 'plané mode': when landing mode is engaged above 600m, this gives indications for a 4° (I think, to check) descent which ends at 500m just before LB.
  • [ ] During phase 1, steering command towards waypoint LB
  • [ ] TILS flight director for phases 2/3.
    • [ ] Displayed distance is computed from glideslope indication and barometric altitude.
    • [ ] Phase 3 should engage when intercepting the glideslope, not at a fixed 8km. If there is no glideslope, it never engages, and one must switch to optical mode manually.
    • [ ] How to handle non-standard glideslopes?
    • [ ] Careful to handle ILS which are not aligned with the runway (aka IGS): distinguish localizer radial and runway heading
    • [ ] Phase 2 flight director without ILS (there is a description in the AJS SFI volume 1 chap. navigation).
