Hi allI use: (A:Autopilot mach hold var, mach) 100 * (A:Autopilot airspeed hold var, knots) (L:Mach-IAS select, bool) ? s1 10 / 10 % flr l1 10 % 9 > if{ l1 10 % 9 - + } for airspeed and mach window rolling number. How can I limit only the mach numbers to .99 and let the airspeed numbers spin over 9. I tried with "9 min" but no good.

Maybe try.....(A:Autopilot mach hold var, mach) 100 * 99 min(A:Autopilot airspeed hold var, knots) (L:Mach-IAS select,bool) ? s1 10 / 10 % flr l1 10 % 9 > if{ l1 10 % 9 - +} Regards,Roman

Hi,Try this one:(L:ms,enum) 0 == if{ (A:Airspeed select indicated or true, knots) s1 10 / 10 % flr l1 10 % 9 > if{ l1 10 % 9 - + } } els{ (A:Airspeed mach, machs) 0.4 > if{ (A:Airspeed mach, machs) 1000 * s1 10 / 10 % flr l1 10 % 9 > if{ l1 10 % 9 - + } } els{ 0 } } Hope it helps,Jan"Beatus ille qui procul negotiis..."
