😕 how come when i fly to high altitudes in my airbus 319, my overspeed needle drops?

Lower air density. The average density of dry air is about 1.225 kg/m³ at mean sea level, decreasing with altitude.
True Air Speed(in kt) = Indicated Airs Speed(in kt) + FL/2
So is you are cruising at FL400 and indicating 240kts, your true airspeed is 440kts.
