Skynews,
Speed has little to do with it either.
below 10,0000' the speeds are mostly the same, and that's where it all happens.
it's a series of issues, weight, drag and system complexity probably the main ones.
Apart from high altitude aerodynamics, it
does all happen down low, and you can easily get yourself into a high level of hurt in a jet (esp the new gliding types) in which it is harder to reduce/manage energy compared to a Dash 8, from what I can gather from my Prop-for-Speedbrake (D8/Bras) colleagues.
Definitely not difficult, but it is different.
will be ruthlessly exploited by both QF and Cobham management when the contract renewal comes around.
Bring 'em on!
