Yes I have it as an MPEG file - but I'm not sure how to post it. I think perhaps it's too large?

Perhaps someone can help with the technical aspects????

Di :\

If you are using Windows XP, try going to Accessories > Windows Movie Maker and import the MPEG file into there, then drag it into the storyboard area, then click Tasks and "Save to my computer" and play with the bitrates and values until it's a good balance between resulting size and quality.

Diatryma,

How big is the file? If you want to send it to me, I can host it for you.

PM me and I'll see what can be done :ok:

Chopper joyride pilot blamed for crash.......Sydney Morning Herald article October 3, 2008 - .....The pilot of a helicopter which crashed in northern Sydney earlier this year, seriously injuring four passengers, has had his licence suspended.An investigation revealed he was flying lower than his licence permitted and the craft breached weight restrictions.The Bell 206 JetRanger was being used for a 30th birthday party joyride when it crashed just before 1pm on March 1 in a backyard in Arcadia.An Australian Transport Safety Bureau investigation report released today 200801245 , reveals that the pilot's decision to fly low over the residential area breached the restrictions of his private pilot's licence.The report notes witness statements that the craft was and that the It also reveals that the weight of the helicopter when it took off from Bankstown airport was 57 kilograms over the maximum take-off weight for its type, a clear breach of Civil Aviation Safety Authority regulations.
the report states. In testimony to the investigation, the pilot told investigators there was silence in the helicopter after he made a steep banking turn to the left.The craft crashed into the backyard of a family home, narrowly missing two teenage girls sitting in their loungeroom..............Di

Extract from accident report:

"When the helicopter executed the steeply banked turn to the left at low forward airspeed, the inertia in the main rotor blades and main rotor RPM would have decreased, resulting in less main rotor efficiency..."

Anyone who is more aerodynamics savvy than me care to comment on the veracity of this, viz, steep turns result in RPM decrease, resulting in less efficiency??

wouldn't rpm increase because of disc loading and total rotor thrust decrease because of the increase in coning angle? :ooh:

Think you may have to be gullible gulliBell to swallow that one in my opinion. Ask yourself "does the rotor droop when in a turn, no matter how steep?". Question 2. Under what conditions of powered flight does the rotor droop? Simple question me thinks. Governors in the main do a bloody good job and quickly regain any transient droop from a sudden application of power, providing you don't top out of course. Inertia in the main blades???? Can see where they may have come up with this argument, but the effect would be minimal and theoretically getting some what esoteric (fuselage begins turning in the same direction as rotor rotation so the rotor has to speed up in effect to maintain the same RPM with respect to its point of reference, the fuselage)

Poorly worded.
 

Although the author hasn't used the word, is this overpitching?

Although in a turn, heavy aircraft, the aircraft has slowed and pilot has tried to accelerate, is it possible that he has overpitched and this has lead to rotor droop with the resultant bits that the author has then described?

The pilot made some stupid f$@&*%g choices and got an outcome consistent with the choices made.

The author of the report didn't say that in so many words either.
