ISIS INDICATION
STANDBY AIRSPEED AND MACH NUMBER INDICATOR
The airspeed indicator is displayed by means of a black tape with white
indications, positioned vertically in the left part of the display area. The
airspeed scale is linear with fiveknot graduations from 5 to 250 Kts, tenknot
graduations from 250 to 520 Kts and digital values every 20 Kts. This tape
moves up and down to indicate the A/C actual speed value in front of a fixed
yellow reference line.
When the airspeed data is not valid, a red SPD flag is displayed in place of the
airspeed scale.
The Mach number is always computed. When the Mach number is above 0.5
(increasing sense) it is displayed in green in the left bottom part of the display
area, just below the speed scale in green color. It is no more displayed when it
becomes lower than 0.45.
In case of failure, a red M flag is displayed in place of the Mach number.
