Wiz matey, for the first time ever I've gotta disagree with you (must be the beers I had!
).
IMHO an aircraft on a 20/10/5 mile final isn't in the circuit.
The aircraft doing an orbit could be on a 20/10/5 mile final, and not even in the circuit. Just how does this stuff your orderly circuit up?.
If you cannot fly a safe orbit with your gear and flap out buddy, you shouldn't be in the cockpit.
I've only been clattering around for 21 years, so I've got a reasonable idea of what's involved with low level maneouvring. Is it really a good idea doing that sort of thing in a
visual circuit in a largish aircraft such as an F50 or a Dash 8?
Bl**dy hell - why not chuck orbits in a 747 on final for 16R at Sydney if you want? Much better than doing a (ooooohh)
go around eh?!
It's this type of mentality that put QF off the end of the RWY at Bangkok.
