French indeed but IAF used ATGM modified Cheetak using SS11 ATGM..
here's one Blog related to IAF ATGM modified cheetah employed in SAR mission over Spiti valley.
re spoiler pre landing - fighter jets have to shed a lot of speed before landing since they are designed to generally fly at higher speeds, so yes use of spoilers may be required under some circumstances
in civil aircraft there is no such excess speed problem, since they will be designed to cruise at a high speed, but approach at a relatively low speed. spoilers are not normally designed into civil aircraft
IIRC, there was a picture of a black IAF Chetak firing an ATGM over Rajasthan in the BR galleries..
Can't seem to find it now, but here is a pic of 4 chetaks with the ATGM ability taking off..

I have a copy of that somewhere - scanned from some mag or other. Need to locate..will post.

They are very much present on the wings and used as air brakes just like in fighter jets. During landing however I have only see them deployed after at least the main landing gear touches down.

I have seen them deployed on the landing approach where they seem to be used for some "fine control" banking when the flaps are out.
I know civil aircrafts have spoilers / airbrakes. Just that it's a rule not to deploy them during approach when flaps are full down. It leads to immediate deceleration. May be as Lalmohan Ji says above, because of higher speeds fighters need em during approach too. But will it not lead lesser control on banking? Generally aircraft will respond very very slowly for last minute adjustments.
air brake/spoiler deployment is mandatory in civilian aircraft after main gear touch down as a matter of fact they are armed for automatic deployment -quite a few accidents have taken place when the pilots forgot to arm the brakes . Apart from bleeding off air speed it also increases pressure on wheels for effective mechanical braking and safely employ reverse thrust
Shankar Ji. You are right but this happens only after touch down. In Sukhoi's Pics in previous page the pilot was full flap down, full spoilers and parachute deployed before touch down, thats why the question.
Some one had asked how does a Water barge looks like when one of them was inducted in September. I found them standing on the dock during PFR 2011. i can't recollect who asked, hopefully he sees it.

Sri I have never seen a pic of a Sukhoi or any other aircraft with chute deployed before touchdown. Which one are you talking about?
Thanks. Honestly - these are the first pics I am ever seeing of aircraft touching down with chutes deployed before touchdown. I didn't even know it was done deliberately.
Regarding the image of B-47 with chute deployed before landing I found info that its approach speed was too fast and here is a forum post in some forum about that. No independent confirmation:
Braking chutes came in with the B-47, which actually had two chutes - a small one, deployed in the air, which allowed the pilot to keep the thrust level up on finals (otherwise, the engines wouldn't respond fast enough for a go-around, and the '47 had no airbrakes) and a big one to stop on the ground.
