Landing profile is other way round.

Any chance that Long Ranger will cope with that mission ?
That would put an L4 at gross weight. It would probably do it with a strong engine. The hard part would be the first take off, after that, no problem. An L4 is probably going to run a mil, though.

You need an L4 less than 2,525 lbs and could do it with a full load of gas.

The only option is spend more money. This cannot be done in a helicopter for $800K. You might be able to do it in an L3 with fuel on the other other end but an L3 doesn't handle max GW like an L4 does, IMO. Clearing a 30' obstacle with 1200 pounds in a L3 with 400 pounds of fuel would not be my idea of a good time.

Coulda sold you our A109A Mk II plus Widebody for $800 Kilobucks.

It could do full fuel. Or full pax. Like a sports car, full fuel (long range tank in tail) and 3POB. Or 7 POB and you could go for 45 mins before looking desperately for fuel. But it looked good, cruised at 145kt, Vne 168kt, and the unique Italian habit of never changing its all-up weight - the fuel, when burnt, was then carried on the tailboom as soot.

Makes you wonder what the thought process is for aircraft designers.

I know, I'll give it 6 seats and a 500L fuel tank. Then I'll work out what the MTOW should be and make sure that the certified MTOW (that I decide) is a good 300kg less than that. That'll f**k them. Then I'll take an engine capable of doing the job de-rate it so that they couldn't get it off the ground full up even if they wanted to. Job done!

As an L3 pilot, totally agree that you won't be able to carry that load and full fuel. But you can get a nice L3 for $700K, so I think it makes sense to double check that there's no way to carry (much) less fuel. Otherwise the L4 is probably the way to go... But you won't find a nice one for the budget you're talking about.

Since he has a 206 he already knows about the TT straps...

He could buy 2 R44s, and use a second pilot. You could do that for $800K, carry himself and six passengers and full fuel! Just saying! Turbine for 50 hours a year eats you up on the fixed costs... With the occasional expensive annual, you can easily hit $2,500 per hour @ 50 hours per year in an L3... More in an L4...

Does he do the full passenger & fuel thing all the time,. Or is that an occasional thing? Because sizing for that mission, and 50 hours a year is going to kill him on fixed costs... If it's an occasional thing maybe it makes sense to lease a 407 and pilot ( with the duals installed ) when he has that mission come up?
