"In Within Visual Range scenarios, the Su3-MKI is expected to excel against the Typhoon because it is a highly manouevrable aircraft. But when it comes to longer-range combat exercises, the Sukhois have been 'less successful'.
And this too
"The kill ratio depends on how the scenario has been set up, with the Rules Of Engagement affecting the number of simulated kills. These kill ratio claims (of the IAF) should be taken with a grain of salt since they are often used for internal propaganda and marketing purposes and they have very little value unless we have some details about the scenario, the supporting assets involved in the engagement (AWACS, Electronic Warfare platforms, Ground Controlled Interceptors, etc.) and the rules of engangement"
Lastly for your propoganda
Squadron Leader Avi Arya, a Qualified Weapons Instructor responsible for training pilots on the radar and weapons systems of the Su-30, said: "Both are fourth generation aircraft and so are matched evenly, so the learning value comes from the person to person contact, it’s the man behind the machine which matters. All fighter pilots speak the same language, that’s the common thing we have and it’s very comfortable to learn from each other."
