What does "NO TDZ" in the PFD mean?

[Guest Jock in a Frock]

I often see "NO TDZ" in yellow in the PFD (just below the altimeter tape). What does that mean? Is it related to the approach / landing phase of flight?Andy Scholes.

Thanks, both of you, that makes sense now.Regards,Andy Scholes.

"correct me if im wrong but i believe that shows if you havent selected an arrival runway"On the ground, the (dis)appearance of the NO TDZ flag is based on the selection of the ORIGIN _airport ICAO_ on ROUTE page 1. The selection of a Co Route should also get rid of the flag (because this contains origin airport info).Cheers.Q>
