#2How does the TLS work with multiple aircraft landing at once? With ILS, the signal broadcast is static but it seems like it will now be per aircraft.

I would expect that these runways are not high volume. Temporary/shifting/special needs.

The entire fleet qualified for McMurdo seems to be six planes and three helicopters, if I'm reading this right.

I would guess it to be pretty rare that multiple aircraft would be on approach at once, and if so, I'd imagine one could hold at a distance to allow approaches to be serialized.

This is about McMurdo. I'd be surprised if they ever had multiple flights landing at once.

#6There a couple companies that make a DILS where the localizer and glideslope can be temporarily deployed. The intent is for emergency or short term use.

There are a few other airports that have this, and my understanding is that only one aircraft can do the approach at a time. If another plane tunes in the ILS they will see the localizer and glideslope indications for the other plane.
I’m not sure how the TLS figures out what transponder to look at, I guess either the controller enters in the code of the plane on approach or there’s some reserved transponder code for the approach.

I've flown to/from McMurdo on a total of 4 types of planes... C-17, C130 (kiwi AF), L-100 (Safari, contracted by Italian antarctic program) and LC-130 (to/from pole).

#9Year round aviation access to Antartica. Well Done! Every step towards McMurdo becoming a normal city despite its location seems like such an incredible accomplishment.
Can this work at pole station too? I realize there's a lot of other considerations landing there in the winter (fuel freeze temp?) but the less isolated it becomes, the more science we can get.
