Karon Posted February 1 Posted February 1 (edited) Hey folks, I made a quick video about a topic that I considered well explained in the manual, but given the feedback, it is apparently less intuitive than I thought initially. So, here is a neat navigation technique: "leapfrogging". Since the AN/ASN-46A can store only one point, the WSO (Wonderfully Sexy Operator) can apply this method to ensure no delays when switching waypoints. Also, it enables bullseye / other references whilst maintaining the ability to immediately revert to the current steer point and vice versa. The idea is well described in the manual: TGT2 is used for navigation, thus leaving the Target Counters free to be manipulated. As the SP gets close, the WSO can input the new point latlongs, then turn the Nav Comp Mode knob to RESET. This causes the memory to be overwritten. Now, the GIB (Gorgeous In the Back) can switch back to TGT2, and the BDHI will show the new nav info. If you are confused, check the video or the article below.

The next videos will be about bullseyes in the F-4E (something I already mentioned here) and INS alignment (yeah, no AHRS shenanigans for land-based aircraft!!). Feel free to suggest more simple-but-not-really topics. Post scriptum: shoutout to HB and their SMEs. I have been accumulating content about the F-4 since long before its release, but every time I jump into it, I notice new, subtle but great details.

Karon Posted February 4 Author Posted February 4 Hey folks! This is a sort of follow-up to Leapfrogging and discusses the usage of Bullseye with the AN/ASN-63 INS and -46A Nav Computer. If Leap Frog ops used TGT2 and Memory, Bullseye and similar nav references use TGT1. Let me know if this is interesting for you, I don't want to spam not-useful content 2 3 "Cogito, ergo RIO" Virtual Backseaters Volume I: F-14 Radar Intercept Officer - Fifth Public Draft Virtual Backseaters Volume II: F-4E Weapon Systems Officer - Internal Draft WIP Phantom Articles: Air-to-Air and APQ-120 | F-4E Must-know manoevure: SYNC-Z-TURN
Omega417 Posted February 4 Posted February 4 3:09 was exactly what I have been miss understanding. I was always so confused about how I could be on "TGT 2" and editing the LAT/LONG without it actively changing the display on the BDHI. 1
Zabuzard Posted February 4 Posted February 4 Yeah. The knob is named in a confusing way. As I like to call the options:* TGT 1 - use the coords currently on the panel* TGT 2 - use previously memorized coords* RESET - memorize the coords currently on the panel into TGT 2 1 1

I was always so confused about how I could be on "TGT 2" and editing the LAT/LONG without it actively changing the display on the BDHI. As I mentioned in the first video, at ~2:10, I think it is easier to see "reset" as "re + set" or "set again". If you think about it, the prefix "re-" stands for "redo" or "repeat", in a sense. About TGT1/2, I think you can see #1 as the first, immediate value. Ergo, straight from the target counters. #2 is secondary, or indirect. Therefore, the memory. Or, you can follow @Zabuzard's tip and simply memorise the functions.

Omega417 Posted February 5 Posted February 5 Right, I also have next to 0 time in the back seat. But your explanation makes way way more sense to me now.

Glad it helped I think both F-14 and F-4 pilots need to spend some time in the backseat, whether they fly solo with Jester or a human. Having a decent understanding of "all-thing-in-the-back" definitely helps to better understand properties, capabilities and limitations of the aeroplane.

Karon Posted March 6 Author Posted March 6 Hey folks, continuing the INS Navigation discussion in the F-4E, I started to look into the fix updates methods.
