It is very difficult to decipher some elements in the demo cockpit display. Those who play DCS, MSFS & other simulators might be able to guess better.

Top row:



> AP - Auto Pilot
> AHLD - Altitude Hold?
> ASEL - Altitude Select?
> FD - Flight Director?
> L | G ?
> AT - Auto Thrust?
-------------------------
> NAV - Navigation map/mode active?
> 0.35 206, 0.25 151 ?
> FUEL 2931, 2350 - remaining fuel.
> 027 degree ?
> 6090, 5080 - Altitude?
-------------------------
> SPOO1?
> RT1, RT2?
> VOR - VHF Omni-directional Range?
> TAC - Tactical air navigation?
> IFF M3 - Interogate Friend or Foe frequency select?
> M?
> DISP - Display options?
> 50X TR?
--------------------------
> 02 PKTS BULLS?
> 068 / 102 NM, 273 / X88 NM - may be navigation beacons bearing, distance.
> AMCA TAKE EASTERN PKT ??

Multiple systems status



> 2 circles at top corners with 52, 17 - could be nozzle position open %.
> A/ICE - Engine Anti-ice heating OFF / AUTO.
> Vertical white scale & green bar, range 1-10, AB (After Burner), value 82%, 88% - Engine RPM %.
> Vertical yellow scale & greenbar, range 2-10, value 610, 671 - could be engine temperature.
> Small vertical white cale & green bar, range 0-200, FF value 31, 83 - could be Fuel Flow.
> REMN 2931 - Remaining Fuel?
> INT 2350 - Internal Fuel?
> BINGO 400 - Bingo Fuel mark.
But INT should be total & REMN should be less than that, right?
> HYD1, HYD2 280 BAR - Hydraulic pressure.
> DC 28.0 V, AC 114 V - Electricity.
> OIL 6.6, 6.9 BAR - Engine oil pressure.
> LPL, LPR ON - LP no idea, but on Left & right are ON.
> BPL, BPR - BP no idea, but on left & right.
May be LP, BP are pumps.

Navigation, Map display

There is an unofficial tweet that AMCA will have 6 AAMs in IWB

x.com

x.com

He mentioned IDAX24 & ex-tarangshakti-2024. Do we have any official link confirming 6 AAMs in IWB?

Some static models, CAD, infographic showcase Astr-Mk1 AAM with large fins. Clearly this version is not fit for IWB.




With a little tight fit, 2 SAAW bombs might fit in.
If Astr-1 are staggered then IWB needs to be elongated, but then also neither # of Astr-1 AAMs nor SAAW bombs increase.
Longer the fins of a weapon, longer is the IWB extension required.
If 2 Astr-1 AAMs are removed then total 8 SAAW bombs can be fitted.
W/o any AAMs, 12 SAAW bombs can be loaded.

Similar is the case with Astr-2 AAM with short fins.



There is another CAD online showing that only 4 Astr-2 AAMs or 8 SAAW bombs can fit in.
With little tight adjustment perhaps 2 folding-fin SAAW bombs can be pushed in with 4 Astr-2 AAMs, or 6 SAAW bombs with 2 Astr-2 AAMs.
Maximum 12 SAAW bombs might fit in. Staggering the AAMs would require lengthening the IWB little but that doesn't increase capacity.
If 4 AAMs & 4 SAAW bombs are arranged then it would require to lengthen the IWB more.
But 6 AAMs doesn't seem to fit in.

If AMCA's IWB can be widened & Astr-2 AAMs staggered then similar to F-22, 6 Astr-2 AAMs can fit.
In A-G only mode, it may allow total 16 SAAW bombs.

There is a perpendicular bottom view CAD available for Astr-1 in IWB of AMCA


And there is one for Meteor or Astr-3 SFDR but angled, not clear.


If someone has a perpendicular bottom view for Astr-2 or Meteor/Astr-3 SFDR then kindly share, Thanks.

In persuit of improvements, there might be some good news
The unofficial tweet might be true. I lately got an infographic showing AMCA's IWB dimensions to be 4.2m long, 2.2m wide, 0.75m height. The dimension is not mentioned in many other posters.



The Astr-1,2,3 AAMs have same length 3.84m. But unfortunately due to big fins of Astr-1, even staggering doesn't help to fit 3 AAMs/bay, total of 6.
But the Astr-2 with shorter fins can easily fit with staggering.
Bcoz of limited info coming out gradually, the older CADs couldn't show the actual weapons capacity. If we superimpose the actual IWB dimensions to match with Astr-1,2 AAMs then we can see the difference.




In latest CAD by artist Kuntal Biswas, the IWB seems to have been widened, although a bottom view with exact dimensions & capacity is not available yet. The below pic is 2.5 months old now but nobody posted.



Perhaps we all can do small party, i mean wherever we are living. More good news to come gradually.

Fitting Ramjet missiles is a challenge bcoz of their long intakes, it becomes difficult to stagger them.
There is an early render by artist Kuntal Biswas of 2 Astr-3 SFDR /bay, total 4 AAMs, but pic is angled, the bay is short with big gap in between.


He has also made multiple CADs of Astr-3 SFDR BUT with different fin & ramjet intake dimensions.

The 3rd one is the only one with bottom view so if we resize it with IWB then still it will be a TIGHT UNSAFE fit of 3 staggered AAMs/bay.
And if we consider 3 staggered Meteors (AAM CAD by artist "AkelaFreedom") then although it is 6" shorter but its intakes & fins seem to be wider & overflows out of bay.


Editing in MS Paint, Photoshop, etc can produce inaccurate errors.
It is best accurate if the artists themselves produce this kind of images. But most of them don't.

News channels & elsewhere people are talking abot MRFA & only 2 final candidates - Su-57 Vs F-35.
While F-35 would be the most tempting honey trap so far, the Su-57 is under fire too not seen as proper full 5gen stealth. There are many things which can be learnt from current 5gen jets. Some of us are also concerned that it may impact AMCA program. The following is a brief comparison. The "possible" features have to be TIMELY implemented expecially when global tech evolution is at 6gen R&D level.
