Right, right...it is actually controlled by tabs, my slip. Boy, not many
know that either, I'll bet. Anyway, if you pull too hard, they stall, that
is won't move, So you have to relax the back pressure almost completely and
then pull not so hard the next time. Weird feeling when you are descending,
trying to check altitude quickly, and don't know what's happening.

Yes, you learn a lot about Dutch rolls real quick. ...and I did
experience a elevator hydraulic cylinder stall once in a 707. That
was an experience.


Ouch. I didn't know they had hydraulics on the elevator. I thought the 707
was all tab control except the rudder.
I had a pitch problem in an A300 at about FL190 once. That was pretty
exciting, but since it was the automatics that caused it we were able to
disconnnect and get it all back under control. Scared the crap out of us.
We thought we had something on the airframe come loose and cause the pitch
problems. Nothing else made sense until we got down and maintenence
diagnosed the problem. We got a mach buffet recovering (2.5 G) but of
course that part of it wasnt too dramatic because of the relatively low
altitude. It would have been a different story at 330 ( the 'Bus was not
good at altitude)

i retrained a lot of 707 guys on the 727 and the 'Bus and they had the
weirdest way of flying! They'd start to interecept an altitude with
thousands of feet to go sometime. They also used to just about have a heart
attack if you used the speedbrake.

I remember that, there was a reason for it. It'll come to me and I'll have
to get back. It had something to do with persistent or repetitive negative
G, or always maintaining positive G for cabin integrity over time...or
something like that. It's funny because you train people to do things and
sometime don't teach them the reasons why.

No more so than these days. My 757 course was a joke, really. I think it
took about ten minutes to do the engine module and maybe twenty to do the
fuel system, for instance. They don;t want us to play with anything
anymore. On the plus side, the new airplanes fly just like airplanes. Spool
up times are almost as fast as pistons, they're speed stable on approach,
the controls are light. They have real good power/weight. IOW, they're for
kids.

Did you take any of the classes at Boeing? I used to teach the FMCS and
EICAS portions in some of the classes. We used to say in the 777 classes
that when the pilots retire, they won't be able to fly worth a damn but they
will be able to type at 90 WPM. :-)

Yeh. I've heard that one alright. I tend to use FLCH a lot myself!

Nope, never done a course in Seattle. All in house stuff. I did a factory
course in Toulouse once, though. Aeroformation ( their training company)
didn't want us to know more than what was necessary, but I had an ex French
Air force instructor who knew his business who would tell you anything you
wanted to know. Very good.
I may be about to change types, so I might be out there yet!

Bertie,
Ok...I'll send you a prize if in 5 minutes you can tell me what DENTK stands
for.
