Legend/terms:

*All air speeds are IAS (Indicated Air Speed)

*All speeds and climb times are on AEC with the obvious exception of “MEC Settings” section

*Speeds are recorded after AEC radiators fully settle/stabilize to ensure accuracy/consistency both at 100% and WEP.

*Map used is Berlin (15.1 Celsius) for all speed, climb and performance measurements. Smolensk and Sicily are only used to adjust cooling settings once cooling settings are found the plane performance is measured on Berlin to minimize variables.

General Chart Terms:

AEC: Auto Engine Control

MEC: Manual Engine Control

0Rad: MEC setting to Fully closed radiator (fastest plane can go with 0 radiator Drag)

Max Speed Alert: When red warning alert appears on speedometer.

Control Lock Speed: Where elevator/controls start to lock up.

Min Ideal Turn Speed: Minimum Speed in a flat turn without contrails (no flaps)

Min Stall Speed: The slowest a plane can travel without stalling (no flaps)

Max Temp Oil/Eng: Max temperature oil/ engine can get before turning yellow

Climb Speed: The airspeed that the climb tests were done at.

Max Kph: Shows 100% throttle max speed in level flight at given altitude

Time w/WEP: Shows climb to 1000M with WEP followed by top speed in level flight with AEC

Hp drop: The altitude where a steep drop off in horsepower begins

Notes: Notes are any extra info that applies with the following abbreviations:

(H): Aircraft runs hot

(FS): Aircraft has fuel starvation

(DC): Aircraft has Drogue Chute

(AB): Aircraft has airbrake

MEC settings:

Eng Mix: Engine mixture setting %. “-” in chart, means to leave mixture at default setting. If there is a different value, it will be clearly stated as a percentage. (This affects very few aircraft)

Prop Pitch: Prop pitch setting %. Prop pitch will be shown in short hand “Prop100” = (prop pitch 100%) Prop Pitch can also have a color-coded prop pitch setting according to map temperature. Use Color coded Air RB Map Temperature guide to ensure proper settings

Rad Setting Oil/ ENG: Radiator settings will be shown in short hand “Rad100/50” = (Radiator100%oil/50%water). Radiator settings are shown Cold/Moderate/HOT climate. they are color coded accordingly blue/green/Red. Use Color coded Air RB Map Temperature guide to ensure proper settings.

Super Charger 100/WEP: Elevation to shift super gears 100%/WEP while traveling at indicated airspeed. Almost all chart gear shifts are set at 280kph in the chart. Gear shifts dont need to be precise more than within 100M, shifting up too soon is generally worse than shifting up late.

*For some planes like early Spitfires Prop Pitch adjustments are included under Super charger Column . Super Charger gear shift altitudes listed are for the prop pitch listed in the chart. Example: prop pitch adjustments to 100% at 6000M will look like “P100@6000” under super charger column.

MEC/0Rad WEP Top Speed: Shows top speed Using WEP @ 1000M for MEC and 0Rad (0/0 Radiator) This is used to show how much drag effect the radiator has comparatively.

First off, I want to above all thank those of you in the community for constructive criticism, suggestions and ideas that made this guide what it eventually became. with that out of the way, I wanted to give an update to what the future looks like for this guide. Unfortunately, I will not be updating it moving forward, for several reason which I will go into in more detail here.

The changing of flight models by the developers with no notice or announcement to the players is incredibly disruptive and irresponsible. It will silently get players killed in game never knowing that their plane has been changed. in addition, instead of updating the chart as needed, I would literally have to recheck every single plane periodically just to make sure Gaijin didnt change something without telling anyone. This is exactly what they did with almost every single Japanese fighter at the beginning of the year,

In addition to helping players understand their aircraft better, the guide was also meant to highlight some issues found with aircraft performance so they might be adjusted by Gaijin. Examples of this are planes marked with an (H) in the aircraft notes overheat and have auto radiator settings that need to be adjusted. The yak fighter line is good example of this, where the radiators are incorrectly set to 111 Celsius when they should be set to 109 Celsius where the plane actually overheats. This issue is still present in game even after I tried to contact gaijin with this information with a technical moderator and they never responded.

After months of the previous version of this guide being in the Realistic battles section of the forums, a forum moderator decided to move all the charts into machinery of war. This was the same area where historical flight data was and created alot of confusion. It also scattered the guide in several different areas making it less organized. I tried to contact the moderators to put it back under RB at which point they refused. I wont get into more details about it, but in the end had to redo the whole guide in a very specific way because of this delaying the completion of the guide

I’ve tried to help make Air RB a better experience by providing knowledge and tools to better help players get into flying which the learning curve is pretty steep. I’ve also shown where there are things that could be easily fixed and made suggestions in that regard. Unfortunately, the lack of transparency of the developers making flight model changes, the lack of addressing the issues I found in testing, and the negative experience with the forum moderators I don’t see the purpose in providing a guide for a game that wants to willfully stay broken or less than what it could be.

Best,
MOBB

I truly appreciate this guide as someone who loves maximing my plane’s performance and will be incredibly useful for me in the future. I’m sorry for perhaps coming off as selfish, but will you analyze the B7A2 and B7A2 Homare 23 aswell in the future? They’re both amazing as fighter planes aswell that probably deserve to be analyzed the same way as fighters are.

Also, I’m curious, if Gaijin will ever add a fuel slider, will you update the guides according to that? The recent fuel slider suggestions was accepted, which is why I’m mainly curious about that.

Gaijin seems surprisingly resistant to the idea of an actual working fuel slider.

The fuel slider does not work as you would expect in function when it comes to performance effects. Instead of a gradual decrease In Simulated weight there are steep drop offs at specific times for several planes. So the granularity of the slider is not reflecting the granularity of the weight/performance hit.

Example, the effect fuel has on performance seems strange. In testing some planes have the effect from a 30 min full tank would be exactly the same until around the next fuel selection (15 min). So having 15:01 of fuel was the same effect as 30:00 min but at 15:00 performance would improve dramatically.

This effect was noticed in several aircraft during testing. It affects climb, acceleration, turning ability, etc. and it is easily verified on planes affected by it.

It also artificially nerfs some planes performance by forcing them to take larger fuel loads. It’s been broken a long time as mentioned above and gaijin doesn’t really take feedback well.

??? we have a fuel slider in the game already

8

A fuel slider that still doesn’t allow you to lower the minimum fuel and you’re still tied to arbitrary limitations and if what he is saying is true, are mostly irrelevant due to preset performance.

9

As it should be.

Isn’t true in test flight and that is easily verifiable.

As it should be.

Because?

11

Because then some players will just take the bare minimum fuel they can get away with, just to tunnel vision on one enemy for one easy kill and then die right after.
Or heavy fighters suddenly carrying a quarter of their usual fuel and becoming UFOs.

Regardless, this just seems like a bad idea all around.

To be fair they are sacrificing range for this performance. You can already very much do this with many Jets, but it isn’t done a lot due to the questionable practicality.

But right now you have aircraft forced to take more fuel than they could even use in battle time as minimum. Selecting fuel load should be weighing the pros and cons of the effect on weight and range, not just blindly taking the minimum because you can’t use that up anyways and anything more is just silly.

14

Why do heavy fighters need to be weighed down with fuel they don’t need?

15

They are, but they’ll see it as a worthy tradeoff if they’re a worse player and can get one relatively easy kill before dying; it will be a race to the bottom.

I agree, and those should get a 25min fuel load option. But allowing players to pick any fuel amount is not gonna be a good idea.

They have heavy armaments and often a speed, high altitude, or climb rate advantage. Making them more maneuverable on top of that is going to put planes like the Hornets and Ki-83 fighting jets.

16

Fair enough, but then where is the area they can weigh their options? An attack aircraft or bomber player for example might want to take less fuel since he’d have to return to airfield anyways for armament. Similar for fighter aircraft with low ammo, or heavier fighters that might want to be closer in performance to their lighter counterparts, but as a tradeoff need to plan a landing.

Sure players could take the bare minimum for a single kill, but the advantage there is far outweighed by the limitation, and as seen in the jet aircraft that can do this already, hardly anyone does it for that very reason.

The “heavy” part in heavy fighter is not, and should not, be fuel load. It’s the airframe itself that is larger and heavier. Many might have more fuel capacity, but once again in 25min battles this isn’t needed.

Even in reality I doubt they would carry any more fuel than they are expected to need for their assigned mission, which is exactly what players should be able to choose.

17

Totally agree - from a pure game play perspective it made sense to add another layer of complexity (=trading fuel for better performance) - but it kills also one of the last remnants of realism.

A Jet taking off with 7 minutes fuel or a prop with 12 minutes - and going into combat is unrealistic like hell; this whole fuel topic alters actual flight performance and makes 1 vs 1s vs actual irl opponents pointless…

Fully agree - imho all planes should have at least 25 minutes of fuel.

It is extremely disappointing if you get insulted in a match - and you out turn this guy in a dogfight and all of a sudden his engine quits due to a lack of fuel - it kills (at least from my pov) a large part of the satisfaction from such kills.

19

Is it really? No aircraft would ever take more fuel than is needed for the assigned mission.
Sure, the average War Thunder engagement isn’t exactly realistic with the very quick time to combat and capped mission times at 25 minutes, but if we were to assume those things in a real engagement chances are there will be bombers taking no more than 10 minutes of fuel since they don’t need any more to get to target and return, and there will be fighters that take lower fuel loads to increase their capability against the given opponent, at the cost of forcing a resupply when fuel runs low.

It changes it in ways that the same aircraft would be affected by the change in weight in reality too. And even then it’s not pointless, as aircraft differ far more than just in fuel weight. It is simply another aspect that players can choose and weigh their options.
More range gives more time in battle, more time in combat generally means more chances at getting kills. Meanwhile maybe you see that your aircraft was uptiered or is generally on the heavier side, so you decide to sacrifice a bit of that combat time for the slight increase in performance, buy you never know when that might hurt you in a fight.
It adds another strategic aspect to the game, similar to ammo count on ground vehicles taking less ammo for more survivability.

Giving all planes the 25min would at least be a good start, in a battle pre determined to last no longer than that it is unrealistic to fill a plane with more than it can even use, maybe account for WEP / Afterburners, but not the 60+ min loads some aircraft are for some reason forced to use.

Sure, it’s a “boring” kill with such an easy killshot, but there is another way to see it. Some guy was cocky, running lower fuel to gain an edge in his engagements, but this very decision of his, this bad judgement and planning ahead lead to his demise. That is exactly what players should be accounting for when selecting their fuel loads.

Though for simplicity standard in all aircraft should be 25min, not accounting for WEP/Afterburner consumption. That way new players don’t need to worry too much, but still learn about the effect of WEP/Afterburners while more experienced players can choose to change this in either direction to suit their needs.

Snail’s inability to balance and refusal to decompress shouldn’t mean we have to artificially nerf planes instead.

Bombers don’t need 2h of fuel either.

21

I am happy that we have a common understanding!

The rest of your post is from my pov a mixed bag as i don’t see any realism in wt Air RB - except size, shape and skins of aircraft.

I mean if i see P-51 Cs turning with 109s…the US boys had 3 hours to fly to a battle and had to carry 3 hours of fuel to get back home - you might get my point. Same as this mouse aim nonsense in Air RB…but this is a topic for another thread…

Have a good one!

PS: My most flown aircraft has around 58 minutes min fuel :-)
