That’s an interesting point you brought up. I always thought the Fokker 100 was fully RVSM compliant. From what I recall, back when RVSM was being implemented globally, Fokker issued specific Service Bulletins under ATA 34 to upgrade the Air Data Computers (ADCs) and ensure the Altimetry System Error met the strict tolerances for that airspace. Do you happen to know if there's a specific reason why those ATA 34 retrofits wouldn't qualify it, or if your comment applies to certain older airframes that didn't get the upgrade? I’m genuinely curious to learn more about the technical side of this!
