Nige, on leaving a plane after returning from Turkey, I asked the Flight Engineer how do they get the plane to reverse onto the stand; he said we simply run the engines backwards.
I believe your explanation implicitly, so either this man was a fool or he was lifting my leg.....as he was responsible for my safety in the air, I hope it was the latter!  :o :o ::)

Reverse thrust is most definitely not backwards ;D

At least you didn't ask the pilot, who would have pointed and said something like "I get him to pull that lever thingy" ;D

But from what I saw, there was more than one lever thingy - I hope he had been to night school to learn which one?  :-\ :-\ :-\

Ron.

 8 levers ... 4 called "throttles" , 4 called "condition levers",  and along with all the other dials, gauges, switches, levers, knobs, etc etc it took 15 months basic training then 5 months specialist training before you were let loose on one (as a flight Engineer) , and a further 6 months before you were allowed to carry passengers .. those were the rules when I started in 1970 :)

(and he was definitely lifting your leg :) .. there were many other "untruths" that were stated to unknowing passengers .... audio controlled autopilot ... built in shower facilities ..... remote access storage facilities  ... hidden weapons ....   we used to laugh a lot when a "know it all" was easily put in his place ....    :)  )

I wasn't trying to show off or "know-it-all", I genuinely wanted to know - like you do when you don't have anything else to ponder on in a plane. Apart from WTF those screaming kids don't shut up, of course!  >:( >:(

A late friend and retired BA flight engineer on TriStars said it is a very straight forward overpaid job 99.999% of the time, but I was well under paid for the other 0.001%, like when they had a major fuel leak mid-Atlantic! :o :o :o

I said, how did that work out? I'm still here, so are the rest of the flight crew and passengers. 8) 8) 8)

I suppose the job has it`s ups & downs  ;)

Hate being driven, I don`t make a good passenger & can feel travel sick in the back.
Last time I flew, I`m damn sure I could`ve done a better job ;D
Lady pilot was makin us feel queezy just driving around the airport :-X

That was a turboprop out of Southampton, on & off the fickin brakes she was.
My work mate had a death grip on my arm & eyes shut thinking we were in turbulance  ;D
"Err mate we is still on the ground"  ::)

I got chatting to a BA Pilot in a Frankfurt Hotel on a stop over a few years back, after a few beers he said "By the way, the safest place to sit on a plane is in the back row"

"Why is that" I asked

He replied "When was the last time you heard of a Plane reversing into a Mountain"

I was on a flight from Dublin to Leeds yesterday. Sat with a clear view of one engine.

Prior to takeoff I noticed that it was rotating anti-clockwise fairly slowly - I was sat behind it at a window seat & "looking through" the prop if you see my meaning. I then saw it slow down, stop for about 10 seconds & then start rotating clockwise - fairly quickly going up to a fast speed before we began taxiing.

Can anyone explain this - there must be a reason for it.

I recall the Herc pitch can be adjusted such that it can reverse, was that the case Nige? (I know the A400M can).

Negative pitch control is almost certainly governed by WOW systems ::)

Weight On Wheels...

Prevents stupidity/inattention from doing something fatal...like reversing the prop thrust at cruise or raising the undercarriage on the ground... Also provides a trigger for the wheel braking... Brakes won't apply until the main gear is loaded ;)

Only one type of aircraft can deliberately fly backwards, a helicopter. Anything else is falling out of the sky ;)
