In my opinion:
+ Some turnpoints could have a minimum altitude requirement for safety reasons - for example, over highly urbanized areas or near cable cars.
+ Instruments already show the estimated altitude at the turnpoint, so we have electronic support for that.
But:
+/- What if we don’t have enough altitude to reach the turnpoint? Searching for lift nearby could mean a time-costly delay. On the other hand, it could add an interesting twist - a bit like a low final glide, but in the middle of the task, and in the middle of the sky.
- We don’t trust altitude readings as much as we trust 2D GPS position.

"The difference between this or a low level no fly zone is the difference between encouraging safe tactics
And punishing unsafe ones"

I guess that's more a question of a glass half full vs. half empty perspective, stick or carrot, it would achieve the same - but I prefer your positive incentive for AGL clearance approach, as we discussed elsewhere.

But there is a "but": given your current description of spherical TPs (& assuming it's possible for our flight computers to do the maths efficiently & quickly), unless you also change the historically typical spacing of TPs in a comp (I think in the British-Dutch Open Ager in '23, we had two @30km apart), people are still going to ridge run the big stretches in between. So unless I have misunderstood, you only partly solve the problem with spherical TPs...

In another thread, you described it as "popping balloons in the air", instead of picking up TP cylinders.

It put the image of a pilot as Pac-Man gobbling up points on the way around a maze, so what if there was mesh of imaginary balloons (or better, cylinders with generous ground clearance) between TPs? These "breadcrumbs" would be optional, but if you don't "eat" any between TPs, you only score 50% of the distance points for that leg; if you pick up say 5 breadcrumbs between each TP, you add 10% for each, so eating 5 between TPs scores you 100% distance points for that leg.

In effect, flying Pac-Man style, acts like a multiplier on the main course distance, while still setting TP-style tasks as today.

It also allows task setters to set great TPs - we still want the joy of 100+km tasks, right? - but also allows them to incentivise pilots away from known / likely problem areas by not laying down +10% breadcrumbs in those areas. You can still incentivise alternative route choices (flats vs hills) by putting alternative trails of breadcrumbs down.

It is an interesting idea, even though I feel it will be hard to be implemented in all TP's on a task.

But, there is "One particular TP" that it can be implemented increasing safety all the times.

And this is the... "GOAL" I will not give any numbers, but you get the idea. If we have a Goal altitude that a reserve throw is still possible (say 100 m) perhaps the fatality in Brazil, and the accident in Ager, could have had a more favorable outcome...

Again, we are brainstorming in here, I do not "suggest" something out of a "strong conviction" or anything...

Markos, I wasn't there, but I think the fatality in Brazil happened when the pilot was on final approach to land, so no longer racing, with the goal field in the lee of some hills.

Yes, add as many turnpoints as needed.
I wasn’t clear about that, Pac man style is exactly how it was in my mind.

To coax pilots away from the terrain.
Maybe one every 5km, it would have to be tested to know how many work
But certainly not limited to the number we have at present.

PAC man is a great image of it.

For HG, it could be really interesting to have the last turnpoint to a certain altitude so you don't have people going on final glides too low and end up in a lake like in Ager by example. It will not solve all the problems but could help for sure. You can not predict a strong valley brise or sinking areas along the glides...

And accurante altitudes can be a problem, GPS, baro ? How to make sure they are precise ?
