I was asked to try and replicate the canopy flying off when opened during flight in a P51.  I tried in level and a power dive at 500mph and it stayed on.  I then tried in a P40 at 240km/hr level flight and off it came, I was then flying a spitfire and coming in to land, speed below 200km/hr and off it came again.

Is this game code?

Hi!

As BAT is a bundle of mods, many of the planes are mods. And many mod-builders implemented an automatically working canopy-opener for planes in approach for landing, esp. Spits and Hurricanes. This was mentioned to give the pilot a little bit of "Battle-of-Britain-feeling", when landing on grass surfaced airstrips, esp. the invisible ones, as in real life the pilots opened their canopies for easier rescue, just in case... .
Unfortunatly this was copied and pasted to other planes, so some BF 109s open their canopies during approach, which makes definitly no sense.... (see: https://www.sas1946.com/main/index.php/topic,51389.12.html?PHPSESSID=b40fcf7c3cea6a48737735bb69684dfb)

Sometimes you can fix it by choosing another series of your plane (for example a BF 109 E-4 instead a BF 109 E-3).

You simply have to live with that, sorry.

Have a nice day,

Fw.190's especially.  Make sure to close them before you take off.  For me, anyway...

Thanks for the replies, will let the chap who asked me about it know too.

After installing the P-40 opening canopy mod a while back, I found that the opened canopy tire off above some particular speed. Going from memory here, I found that in one or both of the base P-40 class and cockpit class a variable that set this rip-away speed, with a small variability coded in. I increased this value so that it would be more congruent with other cockpits having openable canopies (and no tear-away velocity coded at all.)

is the canopy adjustment something anyone can do, or do you need to have modding know how?  For me it flew off at 240km/hr and in the Spitfire XVI it was below 200km/hr.

This kind of adjustment requires to alter classfiles, which are compiled Java code. I do this without any sophisticated knowledge of Java, via a simple decompiler (called Jode) that 'extracts/creates' the Java file which can be edited with any text editor. Once my changes are made, I recompile and hash the classfiles (with Jode), putting them in a mod folder of my own making.

You must have Java installed on your computer, ideally an earlier version compatible with the 'old' Il-2 code. After going through the process of extracting the classfile, decompiling, editing, and compiling/hashing, it becomes a simple enough task. But having some programming experience is handy; I've worked in BASIC in the past.

Ok, I will skip it and just keep the canopy closed.  Thanks.
