    **** ENORME !!!!!! **** (as always)

    Bravo to all of you guys who designed, developped, tested, piloted and maintained this beauty for 42 years ! :very_drunk:

    Angel,
    Can you confirm that the in-cockpit footage at 2:31 is at x1 speed ?
    The throttle and trim adjustements are very impressive.

    Also, I hope they will keep the N°1 in this beautifull 70-80ies paint job, in a shaltered place.
    It would be great to maintain at leat one in flyable condition as they are doing with the Alyzé.

    I will always remember the engine’s roar of visiting sem and cruz at Lann Bihoué Naval base 30 years ago. I was immediatly rushing out to watch them fly over my house…

    Farewell to the sem, the little French fighter jet who was gliding in the air like a bath soap in an oil bassin. 😎

    2. What type is in the shot from inside the cockpit? (MiG-29?)

    yep

    FYI, there is an excellent serie of 3 articles about the Iraki Super Etendard in the February, March and April issues of “Le Fana de l’aviation” (with a beautifull cover as well 🙂 )

    again, it wasn’t “performing a J-turn”, it was in a spin and recovered… it is explained in the video. You even have the sound of “betty” saying “auto recovery.. auto recovery…” IN YOUR VIDEO

    but I guess you know better what’s going on even than the onboard computer that’s flying the thing at that very moment…

    the guys in there explain:

    when put in “out of control” condition, first, the computer gets the yaw under control (stops spinning) then the controls deflec to put the aircraft into a dive go recover aerodynamic flight

    it is not even about opinion here: you post a video claiming it shows something having nothing to do with what’s in it.. the thing is deliberately put into a spin (falling and spinning) and testing the recovery capabilities of the aircraft… it falls and recovers… and that’s about it

    He is talking about the next move at 2:23

    But boasting about buffeting as a quality, seriously ?

    The vertical transition is impressive (I didn’t put the sound on but I anticipate the pilot reaction). Yoyo up. Ok. Good. Roll is good also until it reaches the limiter at 150kt (release stick).

    *it shows that they still haven’t work that with bigger canard and slightly longer/wider fuselage (for ex).

    What do you mean ?
    AFAIK, the “release stick” warning is triggered by the g-force limiter not by a speed too low. BTW you can clearly see that the warning disappear despite the fact the aircraft is still slowing down to 141 knt.

    5. F-22 aircraft is the only 5th generation no HMDS system, Typhoon, Rafale even MiG-35 are equipped with this system.
    Last time I checked, Rafale did not have any HMDS.

    Scoop :very_drunk:

    Is that a depth charge under an mpa?

    Anyway, good luck to convince me that a Lancaster should be in the “modern military aviation” part of the forum 😀

    The Typhoon offered to the UAE was by far the most capable, the needs of the UAE are not meet by either jet as produced now, the reports are that the UAE ware interested in funding an Mk2 version of either jet.

    I think you”l find it was French industry that dismissed that the M88 was underpowered

    See http://www.defensenews.com/story/defense/air-space/strike/2015/04/19/uae-restarts-rafale-talks-with-france/25870693/

    That does not contradict the fact that the UAE dropped their request on the M88 after having tested the aircraft at home

    Interesting change as the twin-store carrier was just recently considered. Remains to be seen whether this renders the twin carrier obsolete or whether both will be developed. It’s also interesting as a tripple launcher for Brimestone exists already.

    http://www.defense-aerospace.com/articles-view/release/3/164062/raf-mulls-common-weapon-launcher-for-typhoon.html

    That’s an excellent news for the Typhoon ! It will increase its flexibility a lot.
    If they follow the same path as for the Rafale this will indeed make the twin carrier obsolete as you can usually use a triple carrier to carry only 2 weapons. If you don’t screw up the design of your triple carrier, the weight and drags hould not be too different.

    my old Canon EOS10D has a 6.3MPix CMOS sensor that is behind an integerated IR filter which is necessary to avoid color distorsion due to IR sensitivity of the sensor. Remove the filter and you have the IR spectrum covered as well as the visible one. The EOS20D even had a special astrophotography version (without the filter) to use the IR spectrum capabilities if the sensor

    Hold on, your DSLR without its IR filter does have some limited sensitivy between 0.8 µm and 1 µm but this is Near IR (AFAIK, Silicon based detectors wont see anything beyond 1.2 µm), quite far from the bandwidth used by dedicated IR detectors and real IR lenses which can work in the 3-5 µm or the thermal 8-12 µm bands.

    High resolution is much harder to achieve for these spectral bands because of the diffraction limit which directly depends on the wavelength of the photons.

    or is there another particular reason for the 150 miles only supercruise ability in level flight?

    It’s maybe harder to supercruise in clouds ? :very_drunk:

    Look at the chart and satellite pictures

    http://2.bp.blogspot.com/-VWVNI4945As/UUFBm6lXGxI/AAAAAAAAJi4/q3jh9ImD64c/s1600/cloud_altitude_image.jpg

    what does that show :
    1) cloud are often stay at altitude from 1 km to 9 km, if you fly high enough there are often enough cloud from hiding from enemy’s IRST – EO systems

    Sure, I suggest you to hide in the big puffy one on the right :dev2:

    other mean of detecting stealth also have many limitation ,VHF radar are not accurate enough for weapon guide , IR/EO system doesnt work well in bad weather or if aircraft fly in cloud , ESM are terrible at geolocate airborne target

    What if you are using all that at the same time and fuse the data ?
    What if there is no cloud ? Please don’t tell me the F-35 will only fly during cloudy days.

    The F-35 has its own limitations : It is reported to be only moderately stealth in the RF spectrum compare to F-22 and future UCAV, not stealth at all in the IR spectrum, can’t supercruise, can’t compete with 4+ gen aircraft in ACM, will probably be a pain in the *ss to maintain for small Air Forces.

    Conclusion ? Nothing is perfect :p

    Thank god Dassault didn’t fall into that LO Ponzi scheme, hey comrades?

    http://theaviationist.com/wp-content/uploads/2012/12/nEUROn-2.jpg

    Oh wait, maybe they think that LO is relevant for strike as well.

    If they didn’t think so, the Rafale would not have so many RCS reduction features in the first place.
    Nobody is denying the importance of being LO in the RF spectrum. What is debatable is where to put the threshold knowing that there are different ways to achieve good survivability depending on your budget and your technical ressources.

    Every design is a tradeoff.
    UCAV VLO design is an extreme exemple of that fact : not a pound for Air superiority.
