LCA Tejas Mk1 & Mk1A - News and discussions

It's the time it takes to start the engines.

Only the Mig-21 can start without a pilot in the cockpit, since its inlets are on the nose. Which is why it's unmatched for interception. All other jets need the pilot inside the cockpit before the engine can be started.

On twin-engine jets, the engines are started sequentially, so by the time the second engine begins spooling up, the single engine jet will have already taken off. And by the time TE takes off, the SE would have already reached altitude. The Mig-21 otoh would have already reached the target of interest.

TE jets don't take to the air in 2 min, their standard reaction time is 4-5 min.
Can QR SAM batteries on borders (especially earmarked for zones at considerable distance from any airbases) perform this role ?

No, SAMs can't perform this role. SAMs are only meant to kill, whereas QRA requires identification and communication with the bandit.

Once the interceptor has identified the bandit as a threat, then SAMs can engage.

How inlet having in the nose helps to start it from outside the cockpit and why same thing can’t be implemented on jet with side inlets like that of LCA ?

Simple. With side inlets, you are going to be in the way of the air flow. So that's dangerous to people blocking the airflow.


With inlets in the nose, no one's blocking the airflow, so the ground crew can start the engine long before the pilot is strapped in. That saves a lot of time. So the pilot can taxi out as soon as he is strapped in.

Though it sounds like a joke but it certainly seems logical reason.

From a humble 3 legged cheetah to a true Ninja of Indian skies. IAF will soon be deploying Tejas foc on all forward bases. A small fighter with lowest RCS and longest bvraam is a deadly combo for any adversary...😊😊
Isn’t he’s the one who uses catchphrase “Nibba” ?
BTW I consider min 4 BVR and 2 WVR ideal for interception role. Hope to see twin rack pylons on LCA soon.
And why the two WVR look different?

Ninjamonkey seems to have forgotten about the Rafales and Meteors.

Anyway, it's a really good achievement considering the MKI upgrade which should have given us much more than this has been significantly delayed to date.

How is it I-Derby ER when the original Derby missile looks similar?

Derby was integrated into LCA long back. IAF asked NG-BVR only for MK1A.

Form factor/size of I-Derby-er is same as that of normal iderby but has dual pulse rocket motor.
They miniaturized seekers/electronics (which now sports solid state active radar seeker) and used the space saved thus to add additional fuel which is used during terminal phase when second pulse is used. This boosts the range of I-Derby-er to over 100kms...😊

That was not the question.

How do you identify i-Derby ER In above LCA picture.

PS: why there is so much patch work ?
Is the paint used by HAL is not upto the job ? @randomradio
