Hmmm ........disabling a critical safety feature makes perfect sense.

Nonsense. I've never needed one in 7000 hours of soaring - how critical can it be? Arguably,
someone with one is more likely to need one for safety, because they think they have an "out".
Also, it's been prohibited in US contests for 50+ years, and I don't recall a single fatality
linked to that prohibition.

I spoke with a pilot who flew in the Sierra wave many years ago and inadvertently went into a lenticular. See https://rec.aviation.soaring.narkive...-reno-pilot-ok. He had an artificial horizon which wasn't on. He considered it a safety feature and thought it was possible to get on soon enough when needed. Before he could get it on his wings came off. Today with LXNAV you can get to the AHRS with an instantaneous single click. The outcome may have been different today.

You can find stories in soaring books of pilots who were sucked up into thunderstorms.

My sailplane came with an artificial horizon. The previous owner considered it a safety feature. I removed it after installing an LX9000 with AHRS.

I don't recall an a single competition fatality linked to AHRS prohibition. However, it doesn't mean it won't happen.

I the end, after an accident, no one wants to explain why disabling a safety feature was required to enter a competition.
