EW Suite Controller (EWSC): M/s Indra’s EW Suite Controller (EWSC) pre-integration was successfully accomplished in DSI Lab. Chaff & Flare Dispenser (CFD) made by Air Weapons Complex (AWC) has also been
interfaced with EWSC, and pre-integration has been verified in DSI lab.
did you guys miss this part? after the ALR-400RWR integration, now the EW suite is changed to Indra's EWSC.
I once asked about it but seems not much information is available about the sys .....
More than 1/3rd of all fuel? :o Where did you come up with that number my friend?
According to the Raymer aircraft design methodology the fuel fraction used up for warmup, takeoff and landing is taken at around 3.5% based upon historical trends.
You are quite right that topping off in the air saves a lot of fuel but warmup, takeoff and landing taking 1/3 or 33% is ridiculous.
I did some rough calculations using historical data estimates and a landing, warmup and takeoff cycle that would be added extra for a non aerial refueled mission would be 5% of the total fuel.
So you save that 5% fuel that can be used for loiter or cruise.

Hi,
1/3rd consumption is not ridiculous---it is pretty close. 5 % is way beyond ridiculous----if such was the case---loiter time would be no problem for any aircraft in the world.
I remember as a teenager 42 years ago----my dad's friend an aeronautical engineer for PIA at Karachi airport told me that the Boeing 707 consumes more fuel on take off that flying from Karachi to london---second thing he stated was that the fuel is like refined kerosene oil.
So---when I went back to my college---in my physics class I excitedly bring out this information---. That physics professor Khurshid was his name I believe in 1974 at degree college asghar mall rad Rawalpindi---that moron ripped me another arsehole and called me stupid for stating dumb things----.
So---.
With 24 Rafale and now 46 MiG 29s we can safely assume that Egypt is not going for JFT as previously reported.
I don't why F-16 is not mentioned here. I found the chart that way
Its their right to induct these jets its understood. But its sad instead of going for jets that are totally reliable they go again for rafales. these nato families will surely in future put embargoes for the parts and all and egypt will again suffer.With 24 Rafale and now 46 MiG 29s we can safely assume that Egypt is not going for JFT as previously reported.

So---tell me how do you want to be addressed.
Anybody who could get his hands on better systems wont settle with sub par systems. When we could get our hands on F-16s, we did not drop it in favor of F-20s or other sub par systems that were on offer, though it was more than obvious that F-16s were embargo-prone. In Egyptian's case, JF is not even in the league.Its their right to induct these jets its understood.

ALR-400RWR is by Indra so what have changed? i guess the name got you confused or am i missing something?
the best part is,
the Indra suit controller is integrated which was not the earlier, which creates suspicion that the jf-17 is now integrated with a new EW suite made by Indra.
Sir,If we are to believe something you heard someone 40 years ago then we are to disregard Mr.Raymer. I can assure you Raymer knows more about aircraft design than your dad's friend.
Please read up on Mr.Daniel P Raymer:
Daniel Raymer - Wikipedia, the free encyclopedia
And yes jet fuel is a refined kerosene. JP-4 JP-8 etc.
And I am an aerospace engineer so I can say these things with more confidence than someone who heard it from his dad's friend 40 years ago.
The 707 120B has a 65,600 fuel capacity.
22,000 L of fuel on takeoff and warmup?
If we are to believe you then the aircraft can just jettison it's tanks right after takeoff because it has already expended most of the 1/3rd fuel in them by the time it takes off (or right before starting it's roll, that'd be more practical).
Here are some numbers to back my claim:
JF-17 Internal fuel load 2330 kg
JF-17 External fuel load (2 1100L tanks) 1785 kg
1785/(1785+2330)=0.43 or 43%
So the two huge tanks are carrying 43% percent of the fuel load. Now if 33% of is burnt at takeoff the aircraft has no need for the tanks lol.
