Double D Scan Pattern Removed


MRaza

Recommended Posts

How do you use this mode? Even when you could see the pattern, I found it very hard to get a lock because it moved so slowly I couldn't keep the enemy still in my sights long enough for the cursor to find him. Now I don't even have a visual guide, am I supposed to just point my nose in the general direction of the enemy and sit on his 6 until I get a tone with twitch-reaction on the ucage button to lock him up?

Ideally you're supposed to get a radar lock and let the seeker be slaved / directed by that. Uncage for steady tone and shoot.

Which is what I do anyway since it makes a lot of sense.

 

When and why would you use SEAM alone then? Honestly if my radar was down I'd rather switch to boresight than play the "scan lottery" that SEAM feels like.

I don't think the DD scan is modeled at all now, not even invisible in the background. This is apparently true to life for 9L and 9M variants.

 

SEAM alone could be used in scenario where, after getting tone by pointing nose, pressing SEAM would allow maneuver off nose up to seeker limits while maintaining tone/seeker lock.

 

Boresight now just moves seeker head back to the ADL. I think.....

The 9G variant probably had the DD scan pattern, Heatblur obviously had documentation for this function from sometime/somewhere....

 

The DD scan may come back I guess if HB ever model the early A's and the Aim-9G...

 

Although this is purely conjecture by me and I may be still getting it wrong.

I fully understand your point.

(For me the symbol's scan pattern was a keeper... but, from pilots and SMEs take, things didn't work like that.)

 

I guess, one really is supposed to notice the change in the AIM-9 audio growl tone and be quick to "uncage".

 

However I've believe they'll also modify the on-off-on constant change in scan pattern tone.

As one of the pilots recall, it didn't change so rapidly IRL - which like you mention as implemented at the sim, difficults the seekerhead lock on target.

 

About the bold, and SEAM (which sometimes is mixed up with "Boresight SCAN"):

 

- it provides a bigger area (than Boresight Mode) for target acquisition;

- when the pilot doesn't wish to use a Radar lock;

- or, if Radar lock is lost, SEAM keeps the AIM-9 seekerhead locked on target.

I get the larger scan area but it comes at the price of potentially missing a lock if e.g. the target just passes through the top of the scan area but the seeker is at the bottom at that moment.

 

If you use boresight, point ADL at target, tone, uncage, won't the seeker also follow the target then?

AFAIK, you don't have to be ready to press the SEAM button as soon as you hear a tone, you can press it a bit before because SEAM stays on for 4.5 seconds and if it detects a target while its on, it locks on

Hence it's why they'll tweak it a bit.

Yep - from the NAVAIR manuals it's supposed to also be able to "uncage" in Boresight Mode, see image at thread below, post #28:

Crucial point indeed.

 

I have to test it better.
