There is no way to IFF in the LockOn F-15 under any of the auto lock modes (Boresight, Verticle, etc...). You also cannot IFF when your target is locked. So if you lock someone, and you are unsure if he is friend or foe, you have to unlock, scan him in RWS or TWS, see the little rectangle.. and relock. PITA! The only way to IFF while flying the F-15 is in RWS or TWS mode and scan him to see a rectangle. The Russian birds are able to IFF when target is locked.. and/or boresight.. etc From what i understand, the real F-15 puts a a big X on the lock box if he is friendly. Hopefully ED fixes this in Blackshark. Hey GG.. LTNS :) Do you know if they fixed this? Can you say? lol :pilotfly: Edit: Let me also add.. there is an indirect way to IFF a target afte its locked, if you are clever. By process of elimination, you can check what your enemy team is flying. Once you lock a target, you will get target type on bottom center of VDS. So if you see a MiG-29 there, and you have no MiGs on your team.. fire away and blast that sucker to mars! Unfortunately.. there is alot of mix and match with planes among red and blue, so you gotta be careul with that one. I always try to know where my teammate migs/su's are. This way if i need to use boresight.. im good to go. Its all SA... hope this helps..

ouch

Its a game A Flight simulator you can log time in... A Flight training device (FTD) you can also log time in... (although im not 100% sure.. havent picked up the FAR's in a while) A Cockpit procedural trainer (CPT) you can use towards training requirements (which is basically a piece of cardboard replica of a cockpit) Thats what the difference is between the different products... you cannot log time when playing LockOn (although im sure some do...lol) hi everyone... miss me? :beer:

It did. I edited it. We have a fractional operator here in the states called Flight Ops, force of habit.... :D

He never called me ignorant, he called Swing Kid ignorant, when Swing Kid included "With all due respect" in his post. Im over it, but like i said before, i wont be recommending it ;) So, who gets hurt here?

Its perfectly reasonable to get frustrated in a good debate and fact finding process. However its another thing to call a paying customer ignorant, no matter how ignorant they are, if you want to make money in your business. Maybe im the one who is ignorant, but it just doesnt make good business sense to me. And no matter how accurate he is, Fighter Ops is looking more and more attractive every day. Unless of course Yo-Yo has a hand in their development. As far as im concerned, the customer can call me names, tell me im a liar, or tell me my product sucks as much as he wants, and i'll smile back and say thank you every time if he is buying my product. I understand other possibilities which do make sense for the 25T behavior, such as the idle thrust settings we have discussed. I have no doubt that Yo-yo knows alot more about the 25T than i...However. for something that needs to be pretty precise as a weapons platform/bomber, it sure is a handful to get the thing to slow down.

Yo-Yo, do you work for ED? I see that ED Team is on your avatar, but not sure if that means you work for ED. I was a bit conused about the "ED Tester Team" signatures as well till Alfa clear it up for me that they are just regular customers like everyone else, chosen to do beta testing. If you do work for ED, and Swing Kid is a customer, did you just call your buying customer ignorant? Sorry, it just took me by surprise....:doh:

lol.. there is a very real possibility i have heard the expression, but always interpreted it as "half as much". Thank goodness im not a bartendar or i'd be shorting customers who asked for "half as much again" alcohol in their drink.... ;)

Yeah, he didnt fly the Frog though. I had him doing some practice in the F-15. He's too used to transport category aircraft now that i guess it was pointless to sit him down in front of LOFC.

lol... good one... never heard that before either. Parasitic is the propery terminology. I guess i picked up a few bad habits since my CFI days... ;)

Hmmmm, and just as it was starting to make sense.... oh well...lol "Half as much again" means 1.5x? Ok.. must be a british thing. Never heard that expression...:) I figured the "again" was a typo he forgot to backspace.... see what i get for thinking? ;)

And that makes sense. If the drag acting on the F-15 is half as much as the 25T at that speed, why does the F-15 slow down more rapidly than the 25T having double the drag, plus gear, flaps and speed brakes. I suppose the F-15 speed brake creates all that drag by itself... ? Edit: The residual thrust advantage on the 25T does lend to a better understand of why it seems slippery with all that drag hangin out though.... if in fact its 30% more than the 15 at idle.

Drag is decreasing when you are in a dive, induced drag (Induced drag decreases as speed increases). Parasite drag increases. Over-all drag increases as you accelerate. It doesnt remain the same... Are you familiar with the difference between induced and parasite drag? Just curious, not trying to be sarcastic.

I never said this. Where are you getting this from? Induced drag is decreasing because you are accelerating, not the other way around. Parasite drag is increasing, also because you are accelerating. The over-all combination of drag is less than the thrust vector because you are accelerating. But drag does not remain the same acellerating in a dive as you suggested earlier. Over-all drag increases as you accelerate any moving body. Drag will increase (as you accelerate) where it eventually catches up with the constant thrust force and equals out. In a dive, this is known as Terminal Velocity. Lift and AoA, depending on airfoil design, also does not remain the same while accelerating in a dive. As you also suggested earlier. . agreed, until drag catches up with thrust and you hit terminal velocity, or impact the ground, or rip your plane apart. ;) No, i believe i stated earlier that the F-15C had an 8000lb thrust advantage over the 25T (speaking in simple terms), in an established dive at idle power, because the F-15C is 8000lbs heavier in my test. However, it didnt seem to have an effect since they both peformed rather equally in the clean configuration.

So, let me see if i can understand this. There is a possibility the Cd of wing area is taken into account for the LOFC 25T design... but not all the other stuff like the 10 pylons side by side, the engine cowls sticking out, the square fuse? Plus it nets 30% thrust at idle? Oh man..... lol

And there it is! I always said it felt almost like i had a tailwind when landing the 25T, when it was the thrust acting like that tailwind. If the net thrust vector is 30% higher than the F-15, that explains everything! Well, at least it starts to make more sense. Mind you, we are talking about net Thrust vector and not thrust setting as seen on the guages, because they both show about 40% thrust at Idle IIRC. As far as being able to sit on the runway. Rhetoricallly speaking, If they were both producing 30% thrust, The F-15 will stay still because it is heavier while the 25T will need some brakes. All my dive tests were conducted at idle thrust.

Can you do that for the Flaming Cliffs F-15? I'd be curious to see the difference since they both performed about the same in the dive test.

Have you ever seen a L/D max chart? Why do you think induced drag increases with decrease in speed. Why do you think Parasite drag increases with speed? And what is the speed at which they cross? What happens to your speed when you point the nose down at idle thrust? AoA does not remain the same. Thrust only increases as you roll the nose over. It remains the same once established in the dive, however, you are accelerating. That doesnt mean thrust is increasing. Drag definitely DOES NOT remain the same. You are accelerating. Where did you get this from? You dont reduce lift by pointing the nose down, it will actually increase depending on airfoil design. So i dont know where you got that one from. What i was referring to is that you reduce induced drag as you increase speed (because you are diving). But you also increase parasite and form drag. As speed increases further, you'll start to get compression drag and wave drag. There are actually some high aspect ratio wing designs that will have a "negative" angle of attack at higher speeds to maintian level flight (or flight path/velocity vector) All better now?

Also, my apologies to anyone who was offended by my cocky posting yesterday... I had a few in me and i tend to get a bit sarcastic while underway.... :drink: Parents... dont let your kids DWP! (drink while posting) :thumbup:

huh? I posted yesterday that i would send my resume to you. In a later post yesterday, i told you i decided against it. Today you ask me again for my resume. Today i tell you that i had posted earlier i decided against it. All caught up to speed?

Doest seem so in my dive test. They both performed pretty much equally.The F-15 gained 7 knots over the Su25T, same dive, clean config. Edit: But yes, i do understand your point that the F-15 design should get more draggy at lower speed in level flight. This is due to induced drag (higher AoA for a slower speed on the 15). However, you reduce the induced drag variable when performing dive tests (like changing the relative wind angle in a wind tunnel). And you're also right that im getting too tangled up in something i really could care less about since i dont even fly the 25T ;)

I mentioned in an earlier post i decided against sending you my resume. Sorry bud.... :smilewink:

ground pounders can be... yes. I should have clariifed my statement. My bad.... I should have said, i dont believe the Su25T in the dirty config is more slippery than the F-15C in the clean config with speed brake deployed... or wait... maybe i did say that before. :D I also didnt think the F-15C speed brake could be significantly more effective on an airplane weighing 8000lbs more, than gear, flaps and speed brake combined on the Su25T.

I was able to fit in the test now. Just did it.... The Su25T gained 113 knots The F-15C gained 120 knots. Both airplanes were set to 269 airspeed and 4000 feet in the menu. In game, The Su25T HUD indicated 430 km/h. 640 km/h upon impact. The F-15 hud indicated 255 KIAS. 375 upon impact. Both were nosed over to full deflection until 90 degree dive established. Lowering the F-15 fuel load by 8000lbs to match 33,700 weight of the Su25T didnt seem to make a difference. The F-15 impacted at 375 for both weights.. 33,700 and 41,652. In conclusion, the F-15 gained 7 knots over the Su25T in the same dive, clean configuration. For ground pounder comparison purposes, i tried the A-10 as well. The A-10 gained 100 KIAS in the dive. 20 knots less than the F-15. The A-10 weight was maxed out with full fuel at 31,398.

I agree the F-15C speed brake is effective. Its a speed brake. ;) However, i didnt think that one speed brake would be more effective than gear, flaps AND speed brakes combined, in the same dive, on an airplane weighing 8000lbs less. Thats one damn effective speed brake! :thumbup: Side note: For those getting confused that a heavier airplane produces more drag. Thats not neccessarily true. And in an idle thrust dive, your weight is now your thrust vector. So, basically, the F-15 has 8000lbs more thrust than a Su25T in the same dive at idle power (to keep it simple, will vary with dive angle). Again.. thats one effective speed brake on the F-15 (if the Su25T is accurately modelled). Next test when i get the time (or if someone else wants to try it). Start both aircraft at same altitude and speed. Nose over into a 90 degree vertical dive. Clean configuration for both. Note the speed upon ground impact. Whichever airplane has the highest gain in speed (Impact speed - top of descent speed) is the more slippery (this way we can see how effective that 15 speed brake really was). First i'll try it at the weights tested previously where the Sui-25T is 8000lbs less. Then i'll try it at same weights (if i can get it close), even though the 25T will have some weapons on the wing. Although i can probably reduce F-15 fuel load by 8000lbs. Will have to check.... Unless, someone in the know wants to chime in here and tell us that ground pounders are designed to be more slippery than a fighter. Might save us some time....;) apologies for all my edits My "f" key is starting to go on my laptop... :)
