G-force in an airliner

Postby bm_727 » Fri Apr 09, 2004 10:56 am

I want to make my airline flights more realistic, and I was wondering two things-

1) Whats the maximum rate of climb/descent a pilot will make in normal cruising flight or during the traffic pattern at an airport?

2) What are the maximum degrees a pilot will bank the wings for a turn? (so the pax don't go falling into the aisles ;))

I've been in a 727 banking steeply to circle the Popocatpl volcano in Mexico ..  People were standing in the aisle, with no problem at all.  Remember, when banking, or rolling, it isn't the angle, it's the g-force vectors being applied.

example a test pilot noted for rolling the Lancasters once did so with a mechanic standing behind him ...  the mechanic lifted a few inches, but came back to a stand as the plane completed the roll.  I believe that a good pilot has rolled the plane with an open cup of water and not spilled it all about..

So you could have a 747 in a 60 degree bank and have passengers walking down the isles without any problems ??? :o

I find that hard to believe

Of course. Providing it was a positive G manoeuvre & the aircraft was in a rated turn - although I wouldn't expect it to be banked at anything like 60 degrees in normal flight. No airliner with passengers on board would normally be banked unless it was in a coordinated turn. If rough weather or negative G conditions are anticipated the seat belt lights would be switched on.

I thought the biggest bank angle would be about 45 degrees, at the MAX!

Well, that's what I'm asking ;)
Normally, under good conditions, what would a full airliner be banked at?
Also, what about rate of climb/descent??  Is there a limit?

P.S.- Is that video online anywhere?


P.S.S.-
Hoover set a glass on top of the instrument panel and proceeded to pour iced tea into the glass
I hope he used a coaster! >:(

It was also pretty cool to see him perform at airshows...:-)

No one quite like him...:-)

An exceptional pilot by anyone's standards. Wish I could have been there.

I had a punt round for a clip of his party trick. No luck I'm afraid but I did find a few photos.

The one & only legendary Bob Hoover.

I would imagine that the Kaitak approach turn would be a tiny bit ( ;)) steeper...
So probably the max would be about 15 degress?

I hope he used a coaster! >:(

I was just kiddin' ;D

Judge for yourself.

Maybe someone else can be more specific. I don't claim to know much about these heavy jobs.

The max bank angle for the 737 autopilot is 30 degrees, and that's quite an angle. I think you'll have an aural "Bank angle" warning if you exceed 35 degrees. At those banks, you need very much stab trim in order to not "fall out of the sky"

What I meant was that the Kaitak turn would probably be a tiny bit steeper than *other* typical approaches... ;)

Thanks for the info Nexus! ;D
Now, what about the vertical speed thing?
