Gov. S of California thinks this is a good idea...hmmm
well, I just read that too much testosterone, like if you take body building steroids, can kill brain cells.
The right idea is "flow control" and engine start to wheels up of about 6 minutes...my company also says on first flight of day, engines are to be run 5 minutes prior to takeoff power, not to be confused with take off power.
this same stupid concept of taxiing out and waiting for takeoff AFTER being deiced/anti iced, is partly responsible for deadly accidents.
kudos to flow control...and to branson and the big S...wake up!
anyway, pilots won't stand for it as we get paid from doors closed and OIL pressure on engines.
and you would still have to run the APU for air and electrics.
