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.

As Clare Prop said "Looking at the size of the display box, how did anyone think a 5700 MTOW kg aeroplane could fit into that area? "
The pilot also appeared to obey the 600 meter rule for 'built up' areas, with his downwind track being well out over the water and further reducing his available space.
Questione: Would a PPL ever be trained to do a right hand tear drop timed circling approach, to enable a tighter radius by turning into wind, away from the obstructions in the CDB and away from the low sun ? Would the air display organiser want to see a plan including that, for what was probably one of the few low level displays (a landing) of the day ?

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

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.

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.

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.

Is it possible to agree that the aircraft was in a fully developed spin just before entry to the water?
Fully developed takes about 2 to 3 revolutions to stabilise
