I'm not really sure why you are so fixated on SWY in relation to TODA. The former is critical for ASDA considerations but has not much to do with TODA. Sure, it lives under CWY, where that exists, but such is a quite co-incidental consideration for TODA.

I'm a little confused, the inclusion/exclusion of the STW was at the very core of this thread.
It was [i]always my view[/i] that the SWY had nothing to do with TODA. You did not agree.

I couldn't agree more!

I would hope I didn't give that impression. About the only situation is with a SWY one would expect that, coincidentally there will be a declared CWY extending at least to, or beyond the end of the SWY. If I gave the impression that I was suggesting that the SWY materially related to the TODA, that was not my intention and, for which, my apologies ...

Okay, let us redefine the problem!

Does the Australian definition of TODA agree with the ICAO (Annex 14) definition of TODA (refer to red box below) when there is a SWY only?

I would suggest not

My take is the TODA includes the runway strip (if no clearway) and any stopway would be included by default

G'day Stuart

It's good to see another opinion.

As we all know, the Australian practice is to include the 30-60 m at the end of the runway (call it the "end bit") into the TODA - only if there is no defined CLW. The point to note here is, the "end bit" starts at the end of TORA, which is where the CLW would start if defined. This seems to be the general application of the Australian practice.

So the question is, is the "end bit" at the end of the STW also included in the TODA? If yes, then we have a problem where the STW and CLW are one and the same. This cannot be true. To start with, the STW and CLW have different dimensions and serve very different purposes.

Extrapolation and conflation can be very misleading. Sadly, the new Aerodrome MoS did not explicitly address the question; it simply went silent. At least the old MoS had a bob each way.
