How do you know he's banned...and I am curious..why was he?

SNS3Guppy 13th October 2008 03:17

Two ways to know he's banned: the first is that it says "banned...persona non grata" under his name. That's always a good indication. The second is that you're here, easily identifiable as him...you're the same person, and as always, transparent both for your misunderstanding and your rhetoric.


Since I carry people, reduced thrust takeoffs are a luxury. I am always at max weight - people/Fuel. That said purposely extending my runway balanced field numbers into the stopway for the hope and prayer that the engine inspector will let me take those engines out a little longer seems counter intuitive.
That's a bit of a giveaway, righ there. You have a very poor misunderstanding of reduced thrust takeoffs, and constantly embarrass yourself in a crusade to prove you're right. These comments, that you can't do reduced thrust becuase you carry passengers, are clearly in error, and said in order to push the same tired, transparent agenda. Many of us fly passengers, and have done so for many years, safely using the manufacturer approved and provided data in full compliance with all the applicable regulations, safety practices and procedures, etc, using reduced thrust.

It's you. Painfully, obviously so...hiding behind yet another name because you don't have the maturity, the professionalism, nor the discipline to hold your tongue or have an informed, intelligent conversation.

You're "busted."

With regard to my aviation credibility, I will say this...I do it for a living, and get paid well for it. That's enough I think for you or who you pretend to be. I am curious Guppy, if I am a recent reincarnation of someone your having problems with...how does he get back on? Ergo...what is the net effect of being banned, if he can come back at his pleasure and torture you at will?

You just referred to yourself in the third person.

We de-rate all the time on the Q400 - and with passengers on board. :ok:

'Normal' t/o power (90% of rated torque) is actually used quite rarely, generally for first flight of the day or if specific performance related conditions apply.

For the great majority of flights, 81% torque is perfectly adequate - and it aint exactly underpowered.

I guess it depends on the aircraft...if I flew an F16, I guess at 50% power I could probably climb out looking straight up. Not very interested in reduced thrust take offs that squeak over the fence, just to save corporate a buck. If I can reduce thrust, beat out that second segment climb gradiant with ease...sure why not...no sense having the passengers feel like they are in the space shuttle on climb out. Now just how many aircraft have all that excess power? Most are built to min performance spec to for fuel/range economy...not to mention weight.
