PMDG 744X - No TDZ warning

Recommended Posts

Hi all,Sorry did a search on this but I don't know what I should be looking for:While flying the 747-400X (PMDG) I am getting a "No TDZ" amber warning on the PFD on the right lower corner under the climb/decent rate indicator. What does this mean and how / where do I define a TDZ?Thanks!

"What does this mean and how / where do I define a TDZ?"The TDZ is a yellow and white symbol superimposed on your PFD barometic altitude tape. It symbolises the runway. If the runway/airport is 200' above sea level, a striped symbol appears at 200' on the tape.There is a database in the FMC which includes the heights of all the airports/runways. When you select a departure or destination airport on your Route page, the symbol should appear (You may have to execute the route first, however). I believe that adding arrival/departure runways refines the altitude (not all runway touchdown zones are at the same average height as the airport).Hope this helps.Cheers.Q>
