I agree with
Centaurus....
Isn't this a ludicrous debate?
Lets assume you were doing a circling manoeuvre in marginal visibility and you lost sight of the runway. In reality are you going to continue the approach on the basis of the FMC trickery you've been taught in the sim?
I'd hope not.
This is no doubt one of the trickiest manoevure's out there, but teaching "
IMC/FMC" techniques in the sim to solve a visual problem isn't helping anyone fly the procedure in reality.....is it?
Get your downwind tracking and timing right, compute your radius of turn, fly the required bank angle and ROD and if you screw it up, go somewhere else!
