some suggestions for sim profiles
some suggestions.
1. Manual ILS Course. In case this is inconclusive, maybe you can try it with Localiser signal failing below 15 ft.
2. IRS Drift. Maybe you could try it with IRS drift of some huge magnitude to see if this reduces after localiser intercept?
3. Possibly, a localiser signal that remained available below 15 ft would cause the aircraft to align heading with localiser signal (most accurate input) and not with the IRS heading value for the runway.
Looking forward to your experiment result. (and maybe put in some respectable crosswind since the whole argument is about decrab...?)
