@minusYCore@BuzzPatterson In general the airplane should be about 50ft above touchdown when we cross the threshold ( the dashed lines just beyond those arrows) additionally they may be flying an approach procedure who’s glide path is not coincident with the VGSI.
@DrEliDavid “Three Honeywell TFE731-60 engines power the Falcon 900EX each offering 5,000 pounds of thrust and using a combined and impressive fuel consumption of 267 gallons per hour (GPH).”
The 737-800 burns 850 US gallons (3,200 L) of jet fuel per hour. So don’t fly commercial either?
