My two cents.
Some have mentioned that if you miss the TDZ, then that is a mandatory balked landing. That is in some airlines, not necessarily true. Nevertheless at a minimum you must at least know what the margin of distance is in the event that you miss the TDZ.
For example, on FLYSMART as part of the briefing, you are well served to make note that we have 285 metre of margin should we miss the touchdown zone.
At least then you know roughly what’s a stake.
