Citation Biz jets have the same restriction VMO jumps to 260kts below FL80/8000ft for the same reasons ... we stick to the same rule as Knertius ... whoever sets it off buys the beers
Does have the worrying CRM implications that you won't say anything re speed if your gonna get a beer though
Must be a bit of a pain in the Citation X as its the fastest commercial jet now and still limited to 260kts below 8000ft because of windshield protection.
