Jet engine anti-ice questions

Recommended Posts

In the midst of our winter storm here (the city's pretty well closed down), I got to thinking about FS and engine anti ice.I understand that, like carb heat in small piston planes, anti ice robs some bleed air, thus power, from the jet engine. How much is lost? Does it vary significantly from engine to engine?How about wing anti icing on jets? Do all jets use bleed air there? Effect on engine power?And finally, I'm curious that, if it does rob power, why is deice never simulated on FS jetliners? As is, I flip on anti-ice, engine de-ice etc, with no effect on power. Is it difficult to incorporate?Just the musings of a house bound pilot, thanks for any insights...DaveColorado SpringsFlying with the "J-3" of computers, Ath 900, 512Mb 133 SDRAM, GForce286, etc....my next upgrade shall be truly earthshaking!!!

Most of the current jets, CJ to 777 use or have options for heated leading edges (wings and tail), engine intakes, windows. Since there is an extreme amount of air from a jet engine, I can't imagine any thrust decline. I've seen bleed air for the most part disappear from current jet and turbines. Airplanes built during the mid to early 90s and before tend to have the bleed air.
