Standard atmosphere
ISA conditions at an altitude: 15 °C and 29.92126 inHg (1013.25 hPa) at sea level with the standard tropospheric lapse — the same constants behind the density-altitude sim (FAA-H-8083-25C ch 3/11; ICAO standard atmosphere).
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.
