For the record, we flew 280 till 10000, then 250 till underlying class B then 200 to the OM. It was max legal speed all the way.
I would fill out an ASAP for this. You went below class B and re-entered without being cleared. If flying to a class B ATC will not clear you below it.
I flew Citations for years and would have never flown Vapp from the marker in. That is ridiculous in a class B enviroment. Being professional also includes thinking outside the box a little and flying your airplane to help others. While being safe. I realized I was in a slower airplane and would accomadate...no big deal.
