I wonder how visual circling would work in a plane other than a challenger.
The lack of LEDs must up the thing by at least 20 knots.
correct me if I"m wrong, but adding 10 knots to vref protects you to 30 degrees of bank (approx).
adding 20 knots to vref almost 45 degrees of bank.
fully configured circling in a lightly loaded jet with LEDs must be about what a straight in vref in a challenger is.
I know some circling is done with only partial flaps/leds but I can see the wisdom in fully configured over the airport in a modified teardrop towards the east and coming around to 33 after reversing course over the town.
