Boeing and Airbus TCAS operation on the ground
 

My company's SOPs for both Boeing and Airbus have the TCAS off on the ground until cleared onto the runway. Anyone know if this is standard Boeing and Airbus SOP?

ICAO recommends in PANS-OPS (Doc 8168) and the ACAS manual (Doc 9863) not to operate TCAS II while taxiing, so I hope it's in every manufacturer's SOP.

"TCAS II routine operation on the ground degrades safety. Performances of the ground surveillance equipment (e.g. SSR, A-SMGCS) and of the surveillance by airborne TCAS II units can be compromised if there are significant numbers of TCAS II units operated on the ground. As a result, ATC and the operation of airborne TCAS II could be adversely affected."

Exactly what I was looking for thank you.
