Aside from scary ass night strafe, I've never seen anyone hanging out down low in a Hornet on goggles. Some of the old crusty dudes may have done it but I figure, what's the point in ruining something as cool as low levels with something as crappy as flying on goggles?
When we received the first A4D-2Ns (A-4Cs) in '62, one of the big upgrades was the APG-53A Radar which was supposed to give us "night/all weather capability" thus the -2
N designation. Two radar modes: Search & Terrain Clearance.
1. In search mode, could barely pick up the CV from marshal, couldn't differentiate a CV from a DD.
2. Terrain Clearance mode was advertised to give safe 1000'
'all-terrain clearance' at night or IFR. After extensive testing/practice by A4D-2N fleet and RAG Squadrons in day/VFR conditions, the consensus was loud & unanimous... It would be foolish and UNSAFE to use the TC radar at low level in night/VFR conditions.
From then on, especially after the advent of "Rolling Thunder" ('64-'65ish), the VA/VAH major raison d'etre switched from SIOP to Conventional, and the APG-53A essentially became dead weight in the fleet. Regardless of what the "crusty ol' dudes" in the sims said... I think that had we tried to use the A-4 radar TC mode as designed, many of us dudes would never have become crusty, or OLD!
I am not sure if or how the Marine A-4C/E/M Squadrons employed their radar, and I've heard that most foreign A-4 operators had upgraded avionics (& engines) installed. I cannot recall ever even turning the radar on during the war or after, with the exception of a few radar fam hops as a RAG IP '68-'70.
