According to the declaration of BAES in 1998:

1. The static margin of F-16 is -5% MAC, and it will loss its negative stability at the speed of > or = 1.0 Mach.

2. The static margin of X-29 is -35% MAC, and it won't loss its instability until reaching the speed of more than 1.4 Mach.

3. EF2000 is more unstable than X-29, so theoretically, it will be able to keep its instability at the higher speed than X-29 can. That is why EF-2000 can keep excellent agility and maneuverability in supersonic domain:

"I nuovi Typhoon vedono pure migliorata la loro manovrabilità, grazie alla possibilità di utilizzare il 100% delle capacità del sistema di controllo del volo digitale ed all’estensione delle capacità di manovra fino a 9 g a velocità subsonica e fino a 7 g per quella supersonica."

Translation:
"New the Typhoon also sees improved their maneuverability, thanks to the possibility to use 100% of the system capacity of control of the digital flight them and to the extension of the abilities to maneuver until 9 g to subsonic speed and until 7 g for that supersonic one."

An interesting declaration from an Italian pilot about the radar detection capability of CAPTOR radar:

http://www.airpower.at/news07/0512_4stormo/index.html

Dazu zählt auch eine Sensorperformance welche die italienischen Piloten offensichtlich überaus positiv beurteilen. Und Nuzzo - Gunnery Instructor auf dem Tornado ADV - vergleicht: "Alleine die Radarreichweite habe sich im Vergleich zum Tornado ADV mehr als verdoppelt".

Translating from German to English (http://babelfish.altavista.com/tr):

"The radar (detective) range (of Eurofighter) is more than two times of the radar (detective) range of Tornado F3 ADV."

--> CAPTOR radar's (detective) range is more than two times of the radar (detective) range of AI.24 Foxhunter.

As for the detective range of AI.24 Foxhunter:

http://www.secretprojects.co.uk/ebooks/Foxhunter.pdf

Original AI.24:
185km vs a bomber target, head on engagement.
130-140km vs a bomber target, tailchase engagement.
120-130km vs a fighter target, head on engagement.
75-90km vs a fighter target, tailchase engagement.

Upgrading AI.24 "Z standard" after 1988 (10~15%+ increase in detective range):
204~213km+ vs a bomber target, head on engagement.
143~161km+ vs a bomber target, tailchase engagement.
132~150km vs a fighter target, head on engagement.
83~104km vs a fighter target, tailchase engagement.

According to the data mentioned above, theoretically, the detective/tracking range of CAPTOR today should be:
408~426km+ vs a bomber target, head on engagement --> 245~300km+ in tracking range.
286~322km+ vs a bomber target, tailchase engagement --> 172~256km+ in tracking range.
264~300km+ vs a fighter target, head on engagement --> 158~210km+ in tracking range.
166~208km+ vs a fighter target, tailchase engagement --> 100~146km+ in tracking range.

As for the capability of detective/tracking range, the EF-2000 + CAPTOR today may be no less than the F-14D + APG-71..........

Dude, stop spamming your Sukhoi crap. I've looked at 5 threads today, and you're in 4 with the same post. FFS.

Please keep your basic politeness when you ask someone to do something, Mr. AJAX. There is really no need for you to humiliate me or my article in order to achieve your wish.
