If the visual reference is lost in the circling procedure - same thing applies
Not really - once you depart the final approach track and commence your visual manoeuvre you essentially throw away the published missed approach and the protection built into it. That's the rub with circling - and why they are not to be encouraged, IMHO.
With visual reference lost you have to make a best guess to turn towards the centre of the landing area and get your self back on the MAPt/missed approach track - the grey area in more ways than one.
A balked landing actually
may put you in a better position than losing reference whilst farther away from the runway. At least you have a better idea of your position relative to the airfield...
Be careful out there
