check the vertical loop from 2.50 seconds to 2.59 seconds in this old video posted by poster-bramastra11.

it gives us the measure of its vertical agility.

is it good ,average or bad sir?

Here is a video that Pakis absolutely hate - but there has been no changing of frame rate
LCA (Tejas), JF-17 Thunder turn rate, roll rate and loop comparison - YouTube

I have a Question.. may be stupid ... The Drogue Chute that is deployed is it reusable? If no Is it necessary to use it every time when the plane lands?

It can be jettisoned after landing, collected by ground crew and replaced in the aircraft. Jettisoning is not mandatory. The chute reduces wear and tear on the brakes and shortens the landing roll especially for short runways.

it is awesome rate

Tejas at Iron Fist

 

[Pulkit]

I was not trolling sir...
heard that the FOC of Tejas was being delayed ...
So got worried if that will have any impact on its induction production and on MK2?
Or is it on schedule as now they are saying that FOC only by june 2015?
Is this wrong?

FOC will be in dec. 2014 and if not then next year but most possibly december 2014.

Hi,

I am newcommer and this is my first post on this forum.Having gone through the threads on lca tejas,I have few questions.Can you please answer them to clear my confusion.

a) what is the major advantage of Heavy/medium combat aircrafts over LCA?
I know that MCA or HCA does have more payload,range and higher radar range. But in a strictly Air to Air fight between LCA and Heavy/medium combat aircraft comming from pakistan(assuming range is not a issue for lca here),what are the exact advantages does a HCA/MCA of PAF has over IAF LCA.

b) What is the probablity of survival of LCA from a incomming BVR missile fired from 150 kms which is out of radar detection range of Tejas?I know exact probability is impossible to answer.But i would like to know answer in terms of survavility most number of times/impossible to survive assuming radar detection range of lca to be of 120kms and best pilots are flying it?

c) Can LCA in future/currently take advantage of Network centric warfare(via military satellites or say stationary radars or UAV) to identify a HCA/MCA beyond its radar operational range and fire missile?

I am not a expert.Hence if you feel these question as trivial please ignore them.

Thanks,
power_monger.

@power_monger 1) pakistan don't have heavy fighters aircraft .
.
2) LCA is really difficult to be detected at 150km by pakistani and chinese radar cause LCA have lowest RCS among non stealth fighter
.
later AESA will be fitted on LCA
.
lca beats all pakistani fighter and many chinese fighter
.
and yes, tejas have advantage of network centric data and can send and can gain information of detected fighter on radar.
.
BVR of today have range of 110-120.

 

[power_monger]

Abhi,
My question was more of hypothetical scenario to understand the real advantage HCA/MCA has over a LCA like tejas in a strictly air-air fight especially in conditions where combat range is less than 300-400 kms.

BTW, i think meteor has a range of 350Kms.

 

[abhi_the _gr8_maratha]

@power_monger actually meteor is not used by chinese or pakis but it will be used by indians cause of rafale and it will also be used on tejas.
.
I have already told you that AESA radar for tejas mk2 also will be fitted on mk1 so range will enhance and will be more than 200km
.
Indian Defence News - Indigenous AESA radars for Tejas Mark-2 : Saraswat
.
this is the link about fitting of AESA radar on mk1. I guess it will have range of 250-300km . And it is really difficult to detect tejas at 200km and impossible for pakistani fighter and really hard for chinese (only j10B have chance and J10a is simple kill for tejas)
.
tell me BVR of pakistan and chinese

 

[power_monger]

Abhi,

I think you did not get my point. I have been reading through this forum and many times i keep seeing the statement like 'tejas is no match to so and so Medium and heavy combat aircraft'.

After going through several post,i was able to comprahend that MCA/HCA has primarliy advantage in Range(due to Higher fuel storage),payload(heavier payload) and Radar detection range(Larger the aricraft bigger the radar and hence its range).Manevourability should not be a problem for LCA.

So in a Strictly Air-2-Air fight can tejas give effective fight against a MCA/HCA( assuming bigger radar detection range) especially against pakistan where Combat radius of tejas should be good enough?(Please assume that Pak has HCA/MCA for discussion purpose only). Payload could also become irrelevant as one air-2-air missile should be good enough to destroy any of the fighters.

I am thinking that in above said scenarious(Limited) it is only the radar detection range which is a disadvantage for LCA and if they are worked out using network centric warfare it could give a effective fight against HCA/MCA.

Are my assumptions wrong?

 

[Pulkit]

As many of the experts here will say ... you are comparing Apples with oranges....
LCA cannot be compared in any form with MCA or HCA ...
They are have there own purpose and advantages....

If you understand your question correctly ....
Yes Tejas or any LCA cannot match the ability of higher and heavier aircrafts ....
Just with range and payload higher they become quite superior to a LCA...
Radar detection is also a factor but in todays 4.5 gen aircrafts it can be overpowered or reduced to a certain extent..... not completely ,,,

If you want a LCA to go up against a MCA/HCA then surely your numbers should be alot higher...

mostly before the heavier aircraft comes in your range you will be shot down....

thats why LCA are not air superiority role.... They are mostly interceptors....

But as tthey say numbers can be a advantage if you are able to find it without arms and missiles and able to match its speed Manevourability range till some extent then also might be... it will out run you .....

Are you referring to air to air combat between HCA/MCA versus LCA? In air to air combat there is not necessarily any advantage of one over the other. The detection range of LCA will be enhanced by AWACS and other means.

If LCA is attacking and HCA is defending, a heavily laden LCA will be less agile, and will have to make a run for it maybe after jettisoning load. If HCA is attacking and LCA is loaded for air combat - LCA may shoot down HCA. If LCA on attack escort duty meets HCA air defender we may not be able to say who wins, but with HCA tangling with LCA - the attacking aircraft will get a chance to drop their load on their targets- maybe even damage an airfield so that HCA cannot land there after the attack.

b) What is the probablity of survival of LCA from a incomming BVR missile fired from 150 kms which is out of radar detection range of Tejas?I know exact probability is impossible to answer.But i would like to know answer in terms of survavility most number of times/impossible to survive assuming radar detection range of lca to be of 120kms and best pilots are flying it?

The LCA is a small stealthy design and even missiles will find it more difficult to home in. LCA may "see" the missile 20 km away, but missile needs to get within 20 meters of LCA to do damage.

Can LCA in future/currently take advantage of Network centric warfare(via military satellites or say stationary radars or UAV) to identify a HCA/MCA beyond its radar operational range and fire missile?

yes

 

[abhi_the _gr8_maratha]

@power_monger the bigger the aircraft the more bigger its RCS(
radar cross section). And I am first time hearing that more weight means more powerful radar...... I have told you vial LCA will HAVE AESA RADAR which is more powerful than PESA radar. All pakis and chinese fighter have PESA except j10b of china. So lesser RCS( meaning lesser chance of detection) and better radar. And there will be support of AWACS

Assuming LCA radar detection range of 120 kms,LCA has more than 1.5 minute to escape from a meteor missile shot above the range of tejas(meteor has a speed of mach 4).Isn't 1.5 minutes too big a time to escape?

I assumed that space and weight availibility in MCA/HCA can allow bigger range radars given the technology is same(AESA or PESA)? So am i wrong?

Tejas roared just now twice over my head..

 

[brahmastra11]

Friends, can we stop using the term LCA and start calling it Tejas as it is aleady been named as Tejas ?
