Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
How this is computed
TAS is Mach times the local speed of sound, which depends only on static OAT. Reproduces the ASA CX-3 manual's Planned Mach example: M 0.72 at −35 °C → 433.0 kt.
