The high prices on the 7X have nothing to do with runway numbers......its because of its operating costs and (more so) the fact that Dassault wouldn't lower the price in the recession, thus preserving initial buyers investment. This is normal for Dassault and certainly plays a part in why individual owners are so loyal to Falcons.

Glex, 550, 7X, etc..all these planes perform well on shorter runways. I have flown them all and every one is more than capable of short field, high altitude ops etc....as are most modern business jets.

Rich people care about their investments - and this can drive their decisions once the basics are met (comfort, range etc)....never seen it have anything to do with fpm/thrust ratio with one engine out and other useless hypothetical internet scenarios played out by cessna pilots.
