Can TODA ever be shorter than TORA, under any circumstance? I've always been told that TODA* = TORA† + Clearway.  I can't really imagine what a negative clearway would be, so that leads me to think that it is required that TODA >= TORA.  Interestingly, a colleague pointed out a certain airport (Invercargill, New Zealand - ICAO code NZNV) where the declared distances published by a certain source describe a TODA that is in fact less than the TORA.  

My colleague and I are under the impression that some kind of typographical error has occurred when this source was publishing the data.  However, I can't help but think back to strikingly similar conversations we had after seeing a previously unheard of case where ASDA‡ &lt; TORA.  As it turned out, the FAA had changed how Runway Safety Areas were considered, in such a way that it is totally possible for ASDA &lt; TORA (and we've been seeing it more and more frequently ever since).

*TODA = Take-Off Distance Available†TORA = Take-Off Run Available‡ASDA = Accelerate-Stop Distance Available



TL;DR

I wanted to see if anyone has ever heard of any other case where TODA &lt; TORA, under any regulatory agency.  What would the rationale be if that were the case?
No

Takeoff Distance Available (TODA) can never be shorter than Takeoff Run Available (TORA).

  Takeoff Distance Available (TODA) – The takeoff run available plus the length of any remaining runway or clearway beyond the far end of the takeoff run available.


I had previously downloaded the FAA runway database and determined there is no TODA less than TORA.  The mysterious airport may have incorrect data or the database is incorrect.

FAA Airport Information

The same database shows that approximately 14% of the runways have an ASDA shorter than TORA.  Multi-engine pilots need to be aware of how their aircrafts performance was created and how to apply the correct declared distances.
