If you can't convince them with science, baffle them with bull!!!!.

this thread is full of a lot of baffling!

Does anyone know how sensitive the CSU is on the Mallard? or are they even in effect in this stage of the fatal flight?

Another thing to think about guys in all the fisiks classes, is the CSU is controlling a given RPM not an airspeed. In fact it don't give a rats about airspeed, nor air mass or wind direction. Also its changing many factors including drag and efficiency that directly effect aircraft speed both gs and ais depending on settings.

You do realize that there was to be a display this year as in previous years by aircraft that have a mtow of 7257kg. Just saying.

Manoeuvring inside the display box (Hawks/F18s excluded)? Don't torture us, what has a MTOW of 7257?

That'd be the Air Tractor AT-802 of Dunns Aviation. I'm not so sure that the Air Tractor was confined to manoeuvring inside the display box.

Onetrack: 60 deg AOB / 2G turns will do it nicely if needed !
“Air show in a bucket” ... therein may lie a clue..

Flyag2: What were they doing ? See above. When you say 'was' I assume you mean that they cancelled the rest of the program after the prang ?http://cdn.pprune.org/images/smilies/piss_weak.gif

Laardvark: Complain to Clare, not I. However I suggest she was alluding to required approach speed, and the Mallard book infers using 105+ Kias around base which will take you over the Esplanade (at least) in a left turn.

sincerest apologies - post removed .

Put it back, cx'ing it cans the continuity :)

Just mocking me for suggesting the display box may have been a bit small for an aircraft of that MTOW

Way back in the thread I think it was megan who posted a link to a Mallard flight manual. For all the Popular mechanic theorists arguing about downwind turns have a look at the procedures for landing and where the flaps should be. Also interesting is the intial approach speed and the final approach speed with the flaps down. If he forgot to put the flaps down and then tried to fly at the recommended final approach speed then the crash was inevitable. No extraordinary theory of physics required, just look at the evidence.

Valid point Lookleft.

There is enough photo evidence to determine that.

I just looked. Perhaps everyone should.

Is it possible to agree that the aircraft was in a fully developed spin just before entry to the water?

Capn Rex Havoc, As far as it goes, you are correct, because you are likely to have a low turn rate at the TAS and traditional bank angle at jet stream altitudes.

Autoflight - of course he is right.

And the same is true a 80 deg bank at 300 ft. and whatever wind you care to nominate.

Where the turn rate is at the other end of the spectrum.

Headmaster, et al,
Thanks chaps, it is all so simple, and major airlines like Qantas have had it wrong for years, and wind shear doesn't effect an aircraft, and inertia effects don't count.
Ever heard of a Reference (constant) Groundspeed approach. Probably not.
I wonder why we have bothered with all that training for so many years, particularly to cope with micro-bursts, which are "only" an extreme change in wind velocity, which, in your world, doesn't effect the IAS, and therefor is of no relevance to aircraft performance.
Fortunately, I live in the real world, and have to deal with the real atmosphere, when I am flying real aeroplanes.
Tootle pip!!

PS: Your (not very) smart schoolboy physics reminds me of my old physics teacher, who conclusive demonstrated, on the blackboard, how a man -made satellite was not possible, I disputed his "reasoning" and mathematics and got tossed out of the class. About three weeks later, the USSR orbited Sputnik.

LeadSled, could you please point out which posts said that wind shear, microbursts etc have no effect on IAS?

aka Leadsled, pull ya head in! :}

Fully developed spin? No. Incipient, yes.

Fully developed takes about 2 to 3 revolutions to stabilise

Most of these halfwits are too scared to stall yet alone spin. ;)
But it is OK, they can discuss downwind turns and windshear all day.
