Hi,
SD pseudo ILS  works with the runway threshold coordinates,giving a 50ft too low 3° vertical trajectory.
As we pass over runway threshold at 50ft,the touch-down point is 300 meters ahead,at the approximative
place we see tire marks on concrete runways.Abeam the glide path antenna.
Is-it not conceivable to make guidance towards the touch-down point coordinates in place of threshold ones?

Skydemon pseudo-ILS does take the airfield reference point from AIP - which may be neither at a threshold nor even close enough to the runway in use, see i.e. EGDM when approaching runway 35 the 'aiming point' is 0.8nm West of the runway or EDXR 0.2nm East of the main asphalt runway. Be aware - if you start looking out from 500ft you may not see a runway ...

My opinion: as long as you don't manually input the threshold coordinates from AIP this carries the potential to be a dangerous gimmick if shit hits the fan. Skydemon is a VFR tool by these reasons and it may even not hold until the edge of marginal VFR ...
