TCAS RAs on approach
Can anyone tell me if TCAS RAs are suppressed on final approach to land (and if so below what altitudes)?
At various control zones there are a lot of vfr aircraft either transitting through the overhead or engaged in other tasks close to the approach track of inbound aircraft. While in theory only traffic information needs to be passed there are many occasions when a TCAS RA is reported and is followed by the crew.
If TCAS is suppressed what information does the crew receive about the vfr aircraft?....is it a Traffic Alert as opposed to Resolution Advisory?...and what action would/should the crew take? (Providing they are visual with the vfr aircraft and would otherwise be happy to continue to land).
Many thanks
