Air Show displays is about displaying ACM capability of performing fighter. And before entering into any dog fight it is mandatory for fighter to jettison its heavy load and all non esential loads like drop tanks, bombs and any a2g load. So ersakthivel assessment is correct considering Tejas at BIAS was carrying two smoke generators roughly of the dimension of WVRAAM.
Smoke generators are of much smaller weight and dimension than SRAAM. I have not mentioned A2G missiles and two drop-tanks as dog-fight requisites. But A2A missiles, targetting pod/ jammer and towed decoy radar are essentials for interception, dogfight. T/W ratio of bare-bones Tejas is 1.07. Just enough for vertical climb. With those additional weights for dog-fight, T/W will go down and in the absence of thrust-vectoring, Tejas will not be able to do vertical climb and other intense gravity-defying maneuvers.
You concerns are true on their respective place. But lets take one scenarion for our kind consideration.
4x Derby (each = ~ 165 kg) and 2x Python 5 ( each = 105 Kg) and 1x EL\O 8212 ( ~ 100 kg) thats about 1200 Kg considering weight of adaptors and pylons. Empty weight of Tejas is 6500 and it's loaded weight is 9500 kg ( internal cannon and its ammo and max load of internal fuel) or 25794 lb. F-404 at full thrust delivers 20200 lbf. Divide it and you get TWR of 0.78. That doesn't sound much. But when compared with Mirage 2000 which has TWR of 0.7 and Gripen C with TWR of 0.97, both calculated at 'loaded weight', not at their MTOW ( meaning not with any external armament). And when you know that both of these two jets can perform vertical charlie ( check photos below) when loaded with external armaments the point becomes or should become amply clear.
Offtopic, but Actually Gripen C's TWR at 100% loaded fuel is 0.90, not 0.97. The loaded weight on Wiki is inaccurate. Empty weight of Gripen C is 6800 kgs, add 2200 kgs of fuel and about 100 kgs of pilot and other accessories.4x Derby (each = ~ 165 kg) and 2x Python 5 ( each = 105 Kg) and 1x EL\O 8212 ( ~ 100 kg) thats about 1200 Kg considering weight of adaptors and pylons.

Need to mention that for a object to move vertically upwards, and which is in stationary state, a TWR of more than one is required. And that object will keep going vertically upwards until it runs out of power or reaches its max altitude or ceiling. That however is not the case with a Jet fighter. For a jet fighter to climb vertically upwards it's not necessary to have a TWR of more than 1. They build speed in horizontal and then go vertical and until it bleeds of its energy entirely, it keeps going vertical. And in any dog fight you don't need to touch ceiling every time you pull up. A good dog fighter is all about good energy management. When you need to build energy or bleed one, he knows all, may be she as well. It's about time after all.
I took rough estimates from wiki.
I can't say so without reservation. Gripen has longer range. Its weapon or combat load is greater. And it's a certified 9g puller. In contrast Tejas MK-1 can't carry as much as Gripen C, neither it can go as deep as Gripen C. It has been reported that Tejas MK-1 has pulled +8 g, but no mention of 9 g yet. All in all Tejas lacks in certain aspects of performance with Gripen C. But most of it is due lesser volume in Tejas, but that's because Tejas MK-1 is only 13.2 m long when Gripen C is 14 m. Naturally there got to be shortfalls. And are, indeed.
Here the question is how can the lower weight tejas loaded weight can be 700 KG higher than loaded weight of 300 KG heavier Gripen. People while comparing the plane close their eyes as well as mind. Tejas 6500 KG+2500KG (Fuel)+100 KG pilot is also equal to 9100 KG. From where does those extra 700 KG comes from?
No
No gripen is 8.5 g air craft and how much it actually does ???? Nobody knows. On other hand Tejas has done 8+g repeatedly before foc. AOA is yet to be opened fully and I am very very sure that it will go beyond 8.5 by FOC. We have witnessed a great improvement in STR timing bellow 22 second for Horizantal loop which is faster by atleast 4 second than anything we saw previously by tejas. Vertical loop timing of just 17 to 18 second is best compared to anything , i believe. Marginal improvement in these parameter will make them best and comparable to anything we saw anywhere. And that improvement is going to come certainly with opening of flight envelope and weight reduction. As declared at the time of pulling 8 g, it t was declared that Tejas pulled 8+g and aircraft beheaved nicely. This means that it is still left with a great scope of doing more gs compared to 8g.
No it is 2458 KG internal fuel which is 3034 Liters. 2300 liters turns out to be 1863 KG only which will left tejas to carry 6773 kg of other weight to carry.
Well scope of development is there. I never discounted that. What i did said and will again say is that Gripen pulls more than Tejas at this point. That is at MK-1 pre FOC stage.
Again nothing was said with respect to Naval LCA. It's a different aircraft. It's performance is definitely better than Tejas MK-1. But unknown so far. It is however other thing that there no such thing as Naval Tejas. It's Naval LCA. Tejas is name of only the airforce version. Naval version is till yet unnamed.
Weight of A2A missiles not counted or considered as external load? Anything of this sort is illogical. It's better to wait and see them correct the figures instead of finding out, 'out of the world' reasons. I seriously feel that loaded weight figure of 9800 is out of date, old figure hence incorrect.
It's not just about fuel load. But also at what thrust your aircraft handles it. In other words how much of thrust goes into managing extra drag that is there in case Tejas MK-1.
Cannon and internal fuel tanks are part of empty weight. When loaded with their complement that is ammo and fuel, the weight that you get then is called loaded weight.
