My son has amblyopia in the left eye. He is 20/20 in the right, 20/40 in the left. He currently is a multi engine private pilot about to take his instrument check ride, with a third class medical no limitation, trying to get a first class through a medical flight test. We are trying to set up a SODA ride, but the local flight surgeon is saying that the federal flight surgeon in DC is requiring that the Flight Medical Test be done in a transport category airplane. Anyone ever heard of this??? I’ve searched high low and every pilot that has the same condition has taken the SODA ride in a trainer. I asked the local flight surgeon exactly how we are supposed to rent a 737 or G650 for a checkride, and they said that the ride can be done in a Full motion flight simulator, which should only be about 8k an hour. Where is this coming from? Anyone heard of this??
