MiG-29K with fuel tanks.

Huh, a Mig-29 with four wet pylons, you do not see that everyday, even with two underwing 1150l tanks it is a rare sight. Note that two outboard pylons protrude from the wing surface a little bit more than inboard ones placing attached FT`s below.

No one noticed yet, wing fences are there…..what a satisfaction :D:D

It’s difficult, with the wing being so high off the ground……

But I got as close as I could……….

It looks tall enough to be an aerodynamic fence ???

Ken

Voilà! thanks for detailed pics Ken, it is an aerodynamic fence indeed.

so why the switch from putting them inside the radomes to outside the radomes? Why is that more benefitial? why does a modern f15 still have them inside while a modern f16 has them outside, when they both feature more or less same radar technology?

What do you think where is the frictional charging during flight higher, inside or outside the radomes? Agree with Trident, the pitot-static system attachments are used to ground the fiberglass radome as well.

Very good point. On the other hand, it isn’t far fetched to expect flight hours of 60-70 per annum in many African air forces so…

You are being optimistic about that at least to say, most likely the aircrafts were grounded with a first serious maintenance issue, bcs most of the resident tech.staff is lazy and uneducated, a common problem with undeveloped countries in Africa.

Martinez, why do you suggest the L-39s are unlikely to be serviceable ? Not saying you’re wrong, just asking.

Because after overhaul we cleared those aircrafts for a calendar life of 8years or 1500 flight hours. 😀 Do the math and you will agree with me, they can`t be flightworthy right now.

You have misunderstood what Boyd was doing.

He was not demonstrating a combat maneuver.

He was winning a bet. Boyd assumed that the opposing pilot would not be prepared for or probably even aware of what was going to happen. The surprised pilot overshot allowing Boyd to get into his six. Whether or not a “guns guns’ situation followed that is arguable.

At that time, fighter pilots were generally unaware of high AOA maneuvers…earlier fighters typically didn’t do maneuvers such as this.

Boyd’s maneuver was a one trick pony. It only worked once on an unsuspecting pilot. The counter is a simple yo-yo off into the vertical…a maneuver that Boyd would not be able to follow due to his low energy state.

I realize that little of this is going to convince those of you who want to believe this silliness. If you want to continue to be gobsmacked by airshow maneuvers designed to astound an uninformed audience, please have at it.

Do not worry, no interest to argue about the cobra manuever usefulness with you, I know a dozen of former and active combat pilots in our airforce, so I do not need to rely on your whatever opinion.

I think the point behind the “Boyd winning a bet” is that any manuever in a dogfight forcing enemy to overshoot is a kind of combat maneuver. Doesnt matter if it is a kind of manuever where you abruptly pitch your a/c on high AOA and decelerate or not. Sure, there is counter to every counter, but what are the chances in real combat that your opponent is aware what your are going to do? Damn, even Maverick knew that this is useful maneuver during his TOP GUN excercises in 80ies…:D Check time 1:35.

Well, perhaps Sukhoi test pilot Viktor Pugachev watched this TOP GUN movie in Moscow`s theatre and then decided to perform on the Su-27. Later on Soviets renamed it to the Cobra maneuver, what was known for decades among US combat pilots.
Anyway, I have the impression from your reply that you`re saying that Boyd became famous in the USAF because of “winning a bet only”, that he was a kind of jerk? I think he must have been one hell of a pilot when winning bets against so many….:D

copy&paste
Like any gunslinger with a name and a reputation, he was called out many times. As an instructor at the Fighter Weapons School (FWS) at Nellis AFB, he fought students, cadre pilots, Marine and Navy pilots, and pilots from a dozen countries, who were attending the FWS as part of the Mutual Defense Assistance Pact.

If you get that from videos where J-20 is on ground doing check out then I would say it is sadly mistaken.

on ground stationary typically these aircraft are keyed with a direct input from stick to surface so all the surface check can be done. all the feedbacks and augmentations that make it what it is in air, are turned off.

nevertheless, during the ground check, some of the control surface movements, e.g. cannards were very abrupt and fast, must admit I haven`t realized that on other aircrafts so far. Do we know something about the J-20 hydraulic system, do they use typical 3,000 psi system to pressurize the control actuators or is it more?
