Tallinnman, what about the Sovereign? IŽd say its hard to find a better performer on the runway, takeoff, SEclimb and landing wise.

With 4 guys youŽd be good for 2300-2400nm range...however playin it safe would be a second stop, say La Mole - Brest (555nm) - Gander (1950nm) - NY (955nm).

Or LFTZ-BIRK (1590nm)-NY (2266nm)

Or LFTZ-LPAZ (1491nm)-NY (2255nm)

[all great circle distances)

Possible TOW at 0 wind at for 3412ft TODA is

15° 30° 40°
29108 27897 26798
which leaves if the airplanes BOW is 18150lbs and 1000lbs payload

9958lbs 8747lbs 7648lbs of fuel available...

with 5 kts of hw its roughly 700lbs more

Max fuel is 11200lbs.

With the given weight for 40° youŽd require a mission fuel for LFTZ-LPAZ of 6758 before reserves at ISA +10 and at a 50kts heaedwind in FL410. Flying at FL450 would see you at 6052lbs required before reserve.

At 30° you`d require 6822lbs at FL410 or 6160lbs at 450...
Thats tight but doable IMO. (all at max cruise btw)

Landing:
MLW 27100lbs.

at 15° LDR is 2649 ft, at 30° 2748ft, at 40° its 2813ft.

If youŽd use a safety factor of 1,25 youŽd be LDW limited at 30° to 26839lbs and at 40° to 25906lbs. That would mean a remaining fuel of (at 4 pax=1000lbs) of 6700+ pounds (at 40°). More than enough to go back to the cheaper fuel in London...you require roughly 5000-5500 including reserves to London at FL370, ISA +10 and 50kts HW.
