I seem to recall one a/c type that I worked on had a forced standby for the xpdr. I think it was a Jetstream 4100, but could be wrong. This disabled the xpdr until weight off wheels. This sounds like the way to go to eliminate spurious TCAS indications.
Would it be possible to do this for TCAS as well, from a flight ops point of view?? i know a few wx radar systems use this.
