Sorry to hear that.

A tour in the RSU is a good idea, as you can listen to the radios, listen to the controller, and watch all the traffic at the same time. It can really help to improve your SA.

Most folks that wash out of UPT do not do so because they can't fly the jet. Most wash out because they can't properly prioritize all the competing noise going on in the headset with the everpresent requirement to fly the jet.
