Test flight for you aviation types. Calling Chuckie!

[Tom]

Knowing there are a number of aviation types and followers in the house, I'm posting this.  I'd love to have been in the 3rd seat.  I use to be in the 3rd seat on cargo 737 flights.  Great view and different responsibilities than the "truck drivers" up in the left and right seat.

If posted earlier, let me know and I'll pull the thread.

Am surprised they didn't do a roll or loop.  Maybe cause it might scare off future passengers?

They should be able to do one.  They did with a 707.  https://www.youtube.com/watch?v=Ra_khhzuFlE  You just need the room.

The trick, of course, was that it was a 1g maneuver the way that Tex Johnson did it.  Jurgen

Air crews have been looping and rolling passenger jets for a long time.  727's used to be a favorite for that.  Not sure about others but should be 'easy' to do.

And sometimes not so well.  Back in the 70's one air crew looped a 727, but, they were a bit low and hit the ground, killing the crew (it was done at night).

So, the question remains.  Why advertise the maneuverability of a jetliner and not do a roll or loop?

That's more in Kirby's bailiwick, but it's a pretty thang.. :)

I have over 5000 hours in the 727 (all models) and was a designated examiner  to give FAA type ratings in the aircraft.

To my knowledge there has never been a verified "loop" of a 727.(or an attempt, come on) Airliners lack the elevator authority to execute a loop which takes a sustained 4+ g force to complete and a 727 will not do this even with full nose up stabilizer trim...its rubbish.

Any aircraft can do a 1 g roll (don't ask me how I know) if you know what your doing. Transport category aircraft are only stressed  for about 1 and a half G's neg. They are not designed for inverted flight and do not have inverted fuel and oil systems.

Yes Tex Johnson got away with rolling the 707 prototype, (1 g barrel roll), but that was a different time. Any body that would do it now in a public demonstration in an air craft not designed with an aerobatic certificate can kiss the career goodby.
