Falcon 900LX long range flight
Good day,
The owner of the Falcon 900LX I recently started to fly asked me yesterday if it was possible to fly between two specific airports, about 4200NM apart, without a tech stop. I just started to fly the Falcon 900 a few months ago and still have used its range yet as I have little experience.
I would like to know, from experience, what is a good climb and speed schedule for such a flight, knowing we will have probably about 6 passengers, max fuel, take off date is late August, and the flight will happen in areas of ISA+10 on average, flying westbound.
Would a start at FL360 and M0.78 be realistic, with further climbs as soon a possible later on, or would FL380 be better?. It would just give me an idea where to start for planning purposes (I can use historical average winds for late August along my route).
Thank you.

Don't want to be quite as sarcastic as the last poster, but maybe it's high time you got on the internet, asked for access to the relevant parts of Dassaultfalcon.com, and did some homework.. There are plenty of resources out there to be had.. even if you can't get access to Falconperf, I'm sure whoever does the flight planning for you can get you access to a good software..
I use arincdirect.com myself, as they provide our data plan, pilot access to the flight planning feature for pilots is included... Most dispatches use Jetplanner, and they never mind giving me access to Jetplan.com to run trial flight plans..
If all that fails, yes, you should still have the performance books are at least a QRH from your initial... Hopefully you did do a type rating on the 900LX, yes?

900LX range
Dear Sir
For Climb 260/.76 for cruise stick to .80, normally for a max T/O weight flight you can start at FL380 or 390 and then follow the book or Performance page for further climb.

If its and LX then its and EASy, go to the alt page and you will see the optimum and maximum. Cross ref with the QRH figures for weight and altitude.
I found on the Falcon that M0.8 is pretty good but you can cheat, climb at profile, then as soon as you can make an optimum height at LRC go for it, even slowing to M0.02 < than LRC book figures will get better than book if time is not the issue.
If you really need to milk it the obviously picking the best winds work, I also found "block levels" and drifting climbs at < 100 fpm climbs can work really well.
It is possible to depart for destination with "Check reserve fuel" showing (obviously having an enroute alternate) and land at destination having made 1500lb more than reserve.
4200nm is entirely possible in an LX but you have to know the destination has close alternates.

Plus, he sits in China(if he put the correct location in his profile), that means you seldom get your optimum level by chinese controllers.
Further I have to agree with some of the other posters - flying an aircraft without knowing it's capabilities(at least!!! as a captain) is kind of - new generation
.
Good luck, for this trip and your further career, you might need it.
EDIT: Having an other read thru your post - I am not flying your aircraft type. You should have optimum altitude tables(if not go for your maximum altitude tables and deduct 2000-4000 feet, should bring you close to optimum). If you don't make it with this levels you won't make it at all.

max fuel
Hi, I work in china on the 7X and I totally agree with the last post max fuel and LRC, the taxi will be longer than you think and you be kept at lower FLs longer!
enjoy the Falcon.
