If Tejas can stay in the air for 40 minutes at 150 Km range, that's more than enough IMO.

@shiphone @Twinblade We have to be careful of these figures since we do not know at what parameters they were calculated. Operational altitudes, speeds, payloads and mission times will be completely different from manufacturer data in ideal conditions. For eg: LCA is not built as a strike...

As I mentioned before while giving the calculations, I did not take into account fuel consumed for taxi, hold, take-off and climb. I did it on the assumption that the aircraft is already in the air and has full fuel, so all the aircraft are equal at that point. Those are not real figures, it was...

Yes. Bingo is the point where the aircraft has enough fuel to go back to base and land, with reserve fuel for emergencies.

It is useless because it has no combat value. That was my meaning of useless. I mean, do you fill up your car tank and then drive at the most optimal speeds in your city along with the most optimal gear change at the most optimal RPM values in the most optimum weather conditions. You...

In an operational environment both Gripen and LCA do 40 mins at low altitudes. The flight profiles are not clear. At higher altitudes, SFC should considerably improve for both and give one hour on internal. Don't forget that this considers supersonic flight time and combat persistence also. So...

Actually, this measure is used. When F-16A reaches bingo they calculate at 3 Kg/mile. Americans use pounds/mile. So that's 7 pounds/mile at bingo. I have been checking out some F-16 figures. F-16A, the aircraft carries 3.1 tons of fuel internally and 3 tons externally. That gives it a...

Re: ADA LCA Tejas - IV Mirage-2000 has a significantly higher fuel consumption at low altitudes compared to F-16 at same parameters, according to Dassault's flight data.

Re: ADA LCA Tejas - IV These are the ranges of different fighters as listed by toan on the f-16 forum. Cross posting. So are you saying JF-17 has completely surpassed the F-16? Let's not forget both designs are very similar, JF-17 and F-16. Note that these are the "actual" ranges of the...

Re: ADA LCA Tejas - IV This 40 min to 1 hour is not strictly the same in every regime. This must be the operational endurance in just one of the many scenarios available. The article also says that LCA conducted a 1 hour 24 minute flight, but without external stores. The journo must have...

Re: ADA LCA Tejas - IV I wanted to point out one thing about the above post. In the Flight data website, the Mirage-2000 and F-16 are carrying huge payloads of external fuel. For the Mirage-2000 it is 2000x2 + 1700x1, that's 5700 litres of fuel over the 4000 litres of internal fuel, that's a...

Re: ADA LCA Tejas - IV That doesn't mean much of anything. If you are talking about Mk1, then size of the array matters not. If you are talking about Mk2, then we don't know anything yet to compare since we do not know what level of processing will be used on Mk2. Thrust has nothing to do...

Re: ADA LCA Tejas - IV Then that doesn't explain away F-35's smaller control surfaces. Fifth gen aircraft, especially if you look at the difference between PAKFA and Su-27, the control surfaces are smaller than what's on their fourth gen counterpart. Okay, but I don't know by how much...

Re: ADA LCA Tejas - IV @Decklander From what I know, both F-22 and F-35 are RSS designs. The basic premise of the designers was that if the aircraft is unstable, or RSS, then they don't need larger control surfaces for maneuverability thereby further reducing RCS. PAKFA is being designed to...

Re: ADA LCA Tejas - IV We are planning on doing the same for our older Mig-21s.All drones today are stable.

My point has always been the same. I used the same in the Chinook vs Mi-6 thread too and same with T-90 and Arjun. If something achieves requirements, then its other qualities are put into play. For eg: Both YF-22 and YF-23 exceeded stealth and speed requirements. Hence it becomes moot. So...

It is not clear if their missile has dual seeker. I suppose the seeker heads can be changed like it is for R-27. So RF seeker for high value targets and IIR for low value targets. The target profile (pictures) is loaded into the database. It will be inertial like it is for all missiles...

There is inertial guidance and then the seeker. Inertial guidance is composed of accelerometers and gyroscopes and a satellite based GPS link (GLONASS in case of Brahmos). Satellite guidance is when the inertial guidance mechanism can accept satellite input. That's about it. Accelerometers...

It is only an upgrade of the first HMS system. No HMD. Shchel-3UM-1. Before that it was Shchel-3UM on Mig-29A. Igor had posted the upgrade list on his blog. Kunal posted it.
