From the Falcon 7X QRH:
ISA MSL
BFL at 42000 lbs (four pax fuel for 45 mins flight plus reserves - approx) 2515 ft / 766 meters.
LD at 40000 lbs 2125 ft / 748 meters (pvt) or 3548 ft/ 1081 meters with 1.67.
You will probably have PCN issues first.
It also has to be a hard surface.
The numbers work. Landing RWY27 at EGLC and making TWY D (2500 feet) is never an issue although you generally continue to TWY B.
