its normal to say when the game starts that " AAS F-86j DiffMF and bla bla bla"
For V0.09 this is normal, but can be disabled by adding the following lines to the end of your conf.ini:
[AAS]
NoSplashStatusMessages=1
Future versions will change this form opt-out to opt-in, meaning that such kind of messages only appear
if there are specific settings in your conf.ini and will be disabled by default. Furthermore, all branding (like the "AAS" in the message you've seen) is removed.
This is already implemented in an internal 0.10 build, which has been provided as open source release for integration of missile code parts into the SAS Jet package.
I expect to have a new F-86J version ready within the coming two weeks.
when it said that the Missiles are disengaged how i can active them again
With the wheel break key, by default that's the "b" key.
On ground it acts like normal (wheel brake), airborne it toggles the missile engagement status in the order AUTO->OFF->ON->AUTO->...
when i fire the missiles works but i cant hear the tone inside the plane
Yes, that's a known bug for the current versions.
Usually this happens when you change the view modes, e.g. toggle some outside views with F2 or F3 or something similar, and step back into the cockpit again. In that case, sometimes the "growl" lock tone isn't audible.
For V0.09, the only possible workaround is to step out and in to the cockpit again until the tone is back as normal.
This is currently under investigation and will be fixed in future versions.
