Missing RWR feature.


Beamscanner

Recommended Posts

The ALR-67(V2) was added to the Hornet with the "Engineering Change Procedure ECP-510".

 

Source: https://en.wikipedia.org/wiki/AN/ALR-67_Radar_Warning_Receiver

 

This RWR upgrade added the following: "INS stabilization for accurate display in high g maneuvers and during high roll maneuvers."

 

Engineering Change Procedure ECP-510 took place in the early-mid 1990s.

What this means is that the RWR symbols should move to counter the aircraft's own movement after initial detection.

 

ie during a high g turn, the symbol should smoothly slide in clock position to continue to match the bearing of its last detection.

+1. We need that badly. AFAIK, our Hornet and Harrier both have the AN/ALR-67(V2), so it should work like it does in the Harrier, I believe, which appears to be implementing INS stabilization.

The vCVW-17 is looking for Hornet and Tomcat pilots and RIOs. Join the vCVW-17 Discord.

Didn't the 88's HUD box do the same thing? I'm sensing a pattern here.

 

Well, we don't have INS really modeled in the first place...

Yea seems like this would be an easy enough function ( given general description) to emulate, to represent the an/alr67 v2.

 

Given its 21st century hornet it would certainly be using that rwr

Video evidence from VFA-105. 

 

Watch the movement of the RWR track - "2" while the pilot makes a right hand bank (9:14-9:20)

 

VFA-105 did not transition to the Super Hornet until 2006. So this is likely the ALR-67(v2), and is not the ALR-67(v3).

Good point, I submitted that clip among others several times that got added to an "open" bug report about the RWR having mixed features from before and after CONFIG/IDENT 92A and thus being wrong both ways, but didn't think about mentioning stabilization.
