[SU10B] AE2 custom parameters tab - no SDK description

There is a Custom Parameters tab in AE2, What is it? (assume cfg values not in
SDK or deprecated).

Hello @DA40CGDFQ Yes, this tab is for parameters that are not tracked by the
Aircraft Editor. You’ll find either parameters created by third parties
themselves if they want to add and parse their own section, or obsolete
parameters. If you see any parameters in that section that you think is still
used by the simulation, please report it to us. Regards, Sylvain
