And if its starts generating false or superfluous warnings, it won't take long before nobody reacts anymore.
We have it now for about 4 or 5 years and never had a false warning. Some airfields are not in the DB yet, but those are very few...Bergamo is in the DB, as I fly there regurlary I can tell you that....
How many have you had ?
Not saying every problem can be cured - BUT it gives you a clue in very rapidly developing scenario, in which humans "often" do have an issue.
Can it overcome the "desire to land" instead of "boltering" into a TS ? Not in every case, but provide with a FACT (e.g."3000ft remaining, Speed 130 KIAS, insufficient") might influence the decision making in a good way, I think.
I have not 'required' the input yet - luckily - and the type I fly lives on short fields.
Still I like having it. Would I fly a runway eatin' machine, IŽd like it even more...
