Here is a lost comm question for all you VFR pilots. If you were based out of a Class B airport and went for a training flight in the local practice area and then lost your comms what would you do? Are you allowed to simply squawk 7600 and barge back into your local class Bravo airspace. You need a clearance to enter class bravo...something you can not get without your radios working... so legally I think you would you need to divert to any other class airport other than class B squaking 7600 and look for the light-gun signals. What do you think?
