Thanks to the many, mostly freeware, aircraft available, I tend to fly quite a variety. Most frequently the B747-400 for long haul by Project Open Sky (with a considerably modified panel), Project Airbus for shorter trips by A320 and ATR72 for shortest trips (by Francisco Sánchez-Castañer or the payware by Virtualcol). Not quite so regularly I fly the excellent freeware VC10 or Trident by David Maltby or Rick Piper's Viscount. The different flying characteristics together with a large amount of scenery, keeps FS9 full of interest. I rarely use FMC. I do use ATC, but I wish they would get their act together so that I don't land less than a thosand metres behind another aircraft. (Go-around ?? !!)
