Yes, that's right. Different aircraft have different Hook-to-Eye distances, so the glideslope must be adjusted for each H/E. In real life the LSO uses IFLOLS lens roll axis to compensate for that. The roll angle is increased when changing from an aircraft with a small H/E to an aircraft with a larger H/E. In FSX we have the glideslope, which is hardcoded and set for the Hornet. That's why you have to fly a little low to catch #3 wire in the Goshawk.
