Converting Mach Number to True Airspeed

convert

Mach Number to True Airspeed (or vice

versa), rotate the inner dial until you see the Mach

No. Index inside the airspeed correction window on

the inner dial. Line up the true or outside air tem-

perature (do not use Indicated Air Temperature)

opposite this Mach No. Index. Mach Number on the

inner scale reads opposite True Airspeed (in nautical

miles per hour) on the outer scale. In Figure 14, at an

outside air temperature of +15°C and Mach 1 (10 on

the inner scale), read 661 knots on the outer scale.
