I wonder if anyone has information or experience of the Viscount 810 series Vno calculation. The earlier V700 and 800 aircraft normal operating speed limit was highly variable and was based on weight without fuel, altitude and fuel remaining. The 810 series, being significantly beefed up for its higher operating weights and more powerful engines, may have had a simpler calcultation. Any info will be much appreciated.
