F-5E Tiger II - Mastery: Part 1 || DCS World

[@knightonwarbeck1969]

Correction; when the air is colder it is THICKER or DENSER. Here is a prime example of this. My father flew the CF-104 at CFB Cold Lake here in Alberta, Canada. He and all 104 pilots LOVED the -40C winter weather. This allowed the engine to produce up to 40% more thrust at take off. A clean CF-104 on take off came close to going supersonic on takeoff. Father was a CF-104 IP Instructor Pilot and always got a kick out of taking students up for their first flight in this -40C weather. Brakes release to leveling off at 40,000ft... 90 seconds. F-15C pilots with a centerline tank and 8 missiles, had to come out of burner before the end of the runway in this -40C weather to AVOID breaking the sound barrier by the end of the runway. Conversely, when my father flew the F-4 out of Shaw AFB in South Carolina, in the southern part of America, takeoff in the thin hot air of summer used much more runway as the jet engine produced less thrust. Takeoff in 110F/50C Arizona was the worst for takeoff performance.

Yeah I do know that but just brain farted for some reason, it’s led to a handful of interesting stories/details though so maybe not such a bad thing. Mach off the runway is mental, what altitude is Cold Lake?

[@knightonwarbeck1969]

@@Bullet4MyEnemy 540 meters/1800 feet. Surrounded by forest and the lake, which helps with moisture and air density. I was busting your balls. We know what you meant and yes, it made for the addition of a great story(s). Great channel, like your content, especially the F-5 content as my father also flew the F-5. Cheers.

[@GunniesLetsFlyVFR]

Yes correct 😂

Some beautiful shots in here, excited for the 7 aces in a day playlist

[@Sovereign_UK]

Those shots you hit at 18:35 are ridiculous 😅

Great video as always. You are correct that there are certain performance boosts in the cold weather, but the reasoning is slightly mistaken. The air gets thicker when the air is colder. We can prove this by observing the ideal gas equation: pressure = density * Temperature. The air pressure at a certain altitude will remain constant.... so if the temperature goes down, the density (thickness) of the air must go up to maintain the constant air pressure. In terms of performance, first of all the airplane engine is receiving more air into the inlet than normal. The inlet area is obviously unchanged, but there is a greater quantity of air entering the inlet than normal since the air is more dense (thicker). The thicker air will result in higher drag, but the increase in drag is outpaced by the increased thrust from the engine. I think theoretically it should be the same with solid fuel in the missiles: the solid fuel will thicken so it will have an increased burn rate and higher thrust, which can increase range if the greater thrust outpaces the increased drag force due to speed (technical caveat: this would be on a total impulse basis, not a force basis) Additionally, your airplane and missile's turning performance is better in the thicker air, since the aerodynamic force on the control surfaces increases with the air density (similarly to the airplane drag). Any pilots feel free to correct me since I'm an engineer but not a (real) pilot. Thanks for indulging me and great flying (again) as always. Looking forward to other videos in the playlist. Cheers

[@Bullet4MyEnemy]

Yeah you’re right, I even know it’s thicker not thinner - hot air rises and all that. Think I just had a brain fart on that one.

[@horse1-1]

@@Bullet4MyEnemy I was certain it was a brain fart but couldn't pass up the opportunity to bore the piss out of everyone

[@Bullet4MyEnemy]

Haha I’m the king of dull nerd shit like that so fire away if you’ve got more 😅

[@petlemons]

I could be wrong, I'm the type of engineer that annoys other engineers by referring to themselves as an engineer. So take all of this with a grain of solid rocket propellant. The thrust of the rockets is reduced overall with higher atmospheric pressure. My understanding is that the momentum thrust is reduced because the exhaust gases cannot freely expand, like they would in a vacuum. The pressure applied by the atmosphere against the exhaust gases impedes the expansion which decreases the velocity. We can see this if we look at the following equation to approximate the net thrust of a rocket engine. Exit velocity is the velocity of the exhaust gases when the exit pressure and atmosphere pressure are equivalent. F= exhaust gas mass flow * exit velocity + area of the exhaust nozzle * (nozzle exit static pressure - atmospheric pressure) Edit: I can't speak at all to how temperature changes would effect the combustion of the fuels themselves. I do know that solid fuel combustion is pretty complex. With some fuel mixtures engineers have been able to define specific geometric shapes to arrange the grains of oxidizers and fuel for different performance objectives.

I love the F-5… wish it could carry either 4 heaters or a 2 heaters/2 sparrows. I’ve always liked its simplicity. Your a deflection shot master in it The F-5 makes me really wish ED could development a way to ask the awacs to intercept on a bandit/group

[@HighAspect]

Great use of energy with the yo yo. Really enjoy your commentary. Seeing the energy cues of your bandit is a skill many don’t have

[@karnyzelijus]

You make it seem so easy! I trialled the F5 for a couple of weeks and made a few sorties on ECW. Loved how easy it is to fly the jet but got killed or ripped my wings every time without a single kill. Not sure I got time for this but I definitely enjoy watching someone who knows what they're doing!

[@Bullet4MyEnemy]

@@karnyzelijus I have around 1.5k hrs in DCS and I reckon the F-5 is probably 10% or more on its own, definitely took a while to get here lol. If you find my first ever F-5 video (there’s a playlist on the channel page) I definitely had a bit of a rocky start with my fair share of wing rips ☹️

[@karnyzelijus]

@@Bullet4MyEnemy I'll definitely check it out. Which blufor plane would you recommend for a noob like me to get into dogfighting though?

[@Bullet4MyEnemy]

@karnyzelijus Probably the F-5 tbh, the systems are straight forward and dogfighting is what it’s designed for - more modern you get the more missiles take over and the less relevant dogfighting is; even though more modern jets are better at it. You’ll see plenty of gunfights flying the F-5 on Enigma’s server.

[@madaxe606]

The description about the F-5 and its quirks perfectly articulates my feelings for the MiG-21. For all its flaws, its still my fave. Dance with the one that brung ya. :) Cheers!

[@AlphaGatorDCS]

great commentary to help others learn the F-5!

[@Siddich]

when the air is cold, it is thinner? nope...must be the other way round.

[@Bullet4MyEnemy]

This has been addressed about 8 times now in other comments, I just misspoke, I don’t even know how I managed to screw it up because I do know already.

[@Siddich]

@@Bullet4MyEnemy hmm. so missiles in dcs perform better in old air?

[@Bullet4MyEnemy]

@@Siddich I guess the oxygen enhances the motor burn enough to overcome the drag penalty, same as with the jet itself. There will be a distance where it levels out to the same time to target, but I felt 9Bs were working pretty well for me compared to normal temps.

[@Siddich]

@@Bullet4MyEnemy but dont missiles use oxidizer and fuel from the inside and not oxygen from the outside? 🤔 i think in war thunder missiles go further in hot air…but yeah, maybe bad comparison. just wobdering how it is in reality

[@bartdebruijn4599]

I love the F5, it's the perfect low tech jet, with good visibility. A bit low on loadout options, but still much fun.

[@ACG_Jaydog]

I was flying this sortie in the A-10 up north being guided by Magic to kill that Mi-8

[@1Skymed]

New to DCS and agree with everything you said about the F5.....love the video and the narration so that I can understand the what and why in regards to your manouvering and thinking. New Subscriber !!

[@charalamposkatsogr8566]

amazing gun skills!

[@DecibeldB]

I used to love it too. It was my favorite module until the crystal wing update :(

[@Bullet4MyEnemy]

I think I bought it shortly after that update came in, there’s definitely something off about it but I manage to work around it 9/10 times.

[@ItsDburch]

Cold air = thicker air. The better performance could be from more O2 into the engines producing more thrust?

[@Bullet4MyEnemy]

Yeah I totally brain farted on that one, cold is thicker, hot air rises, cold air falls and pools. But the performance gains bit still applies, just more from there being more oxygen to burn fuel rather than less drag, as you said.

[@kizvy]

surprised the f-5e doesnt get aim j's in dcs, is the missile simply not added?

[@Bullet4MyEnemy]

It gets pretty much everything up to the AIM-9P5, which is all aspect. Including Js and JULIs - even though I always thought they were the same thing. In this iteration of Enigma’s server there are just restrictions on what you can bring and for the 1960s the limit is 9Bs, 1970s it’s 9Ps. Different servers have different rules and restrictions.

[@AlphaGatorDCS]

When is it best to have the RWR Search turned on? I noticed at times it's on and others it's off.

[@Bullet4MyEnemy]

I tend to switch search off when I’m aware of the threats around me, to look for locks/launches, but otherwise keep it in search to make myself aware of what’s around. Mirage F1s and 21s have decent radars, airfields have SA-8s, it’s good to keep swapping between search on and off just to get an idea of the threats around you.

[@AlphaGatorDCS]

@@Bullet4MyEnemy nice! makes sense, thanks!

[@killkesscmbn]

When do u use manual flaps and which setting u use?

[@Bullet4MyEnemy]

If you want speed, raise them up, if you want turn rate, switch them to auto. The only reason it’s worth doing is because if left in auto the drag they create delays how long it takes to get fast enough for them to raise automatically, if you raise them manually whenever you’re not pulling the stick it’s quite a significant, noticeable increase to your average speed.

[@thejetfighter]

That was a m*ssacre 😀

[@PaddyMcQueen]

Nice video but the theory about cold air is totally wrong, it s depends on the factor your analysing (engine performance vs missle performances) and the air itself (temperature, humidity ecc).

[@Bullet4MyEnemy]

@@PaddyMcQueen Yeah I just totally brain farted, I know that cold air is actually more dense, honestly not even sure how I managed it tbh

@@Bullet4MyEnemy No problem man. ;)
