KPHX has at least 2 published visual approaches and neither has any missed approach procedure. However, all the arrival routes have a lost comms procedure, typically hold at PXR VORTAC at 9,000 ft. Wouldn't ATC expect a lost coms aircraft executing a missed from a visual to follow the lost coms procedure for the arrival route?
