Searching through Aircraft/controls.hxx gives
enum {
ALL_TANKS = -1,
MAX_TANKS = 8
};
but in Aircraft/controls.cxx there's
FGControls::set_feed_tank( int engine, int tank )
{
if ( engine == ALL_ENGINES ) {
for ( int i = 0; i < MAX_ENGINES; i++ ) {
feed_tank[i] = tank;
CLAMP( &feed_tank[i], -1, 4 );
}
} else {
if ( (engine >= 0) && (engine < MAX_ENGINES) ) {
feed_tank[engine] = tank;
CLAMP( &feed_tank[engine], -1, 4 );
}
}
// feed_tank[engine] = engine;
}
If these bits of code are relevant to the problem MAX_TANKS seems
too low - many large aircraft will have more than 8 fuel tanks.
If I understand CLAMP syntax correctly, it's limiting the value to
4, which ties in with the number of tank nodes that are created by
default.
I didn't find any other occurrences of 'tank' in the FG source code
that seemed relevant.
