Recently during a simulator refresher, I was made to do a circling approach. During approach preparation, I insert the circling approach MDA of the runway, I was going to shoot the approach initially, not the intended runway for landing, as I believe it is the right thing to do... but sim instructor did not agree and asked me to insert the circling approach MDA of the intended runway for landing.. later back home, I tried to find what does manual says.. I could not locate any mentioning about it in writing in the FCOMs...
do you have some light to throw on it?
cheers
