Airliners at Displays and Limitations
There's a thread running here entitled "787 video of stunts" (sic) that contains an assertion from the pilots involved that they never exceeded 45' from the vertical and another from an observer who insisted they did, and by a long way. We know this video resulted in some extreme looking manoeuvres that were a result of clever camera angles and editing but it got me thinking.
When a public transport aircraft is displayed there often seems to be a need to present it as though it were a fighter - heaven knows why - which results in unpleasant words like "stunts" being attached to it but we all know the limitations of our particular mounts and its pretty hard to put together a spectacular display when adhering to these (though clever display design and viewing angles help).
So do these display aircraft (think Farnborough, Paris etc) actually get taken beyond their published limitations in terms of bank and pitch bearing in mind you'd have to downgrade the control laws in an 'Bus to do that (I've never flown a fbw Boing) or do they really stick to the numbers?
If they do exceed them how is this achieved from a procedural point of view? Does the display authorisation OK this? The manufacturer? What do the insurers say? The maintenance organisations? Are they on experimental C of As that exempt them from normal limitations? It's hard to imagine that Flight Ops Inspectors turn a blind eye in this litiginous day and age.
How does it work?
