Flight Mode / AIRSPEED OPERATION
The Airspeed Indicator portion of the display will always appear on
the bottom display when oriented vertically and can be congured
to appear on the right or left display when oriented horizontally
(Image 11).
The Airspeed Indicator Display consists of three parts: Airspeed
Window, Airspeed Scale and Airspeed Limitations or Range
Markings.
The Airspeed Window displays the current Indicated Airspeed (IAS).
The digits of the display are enlarged for visibility and increment by
one unit. The units will ‘roll’ or scroll to assist in quick reference
as to the increasing or decreasing nature of the aircraft’s airspeed.
The Airspeed Pointer (triangle) to the left of the window points to
the associated position on the Airspeed Scale of the current airspeed.
Airspeed units are available in Knots, KPH (kilometers per hour) or
MPH (miles per hour). The unit of measure appears below the airspeed
window and can be selected during installation in the Conguration
Mode only. This selection is not available in Flight Mode.
The Airspeed Scale is positioned vertically along the left margin of
the display. The current airspeed is always in the middle of the
scale and indicated by the Airspeed Pointer on the left side of the
Airspeed Window. The Airspeed Scale has numeric indications every
ten or twenty units depending on the unit of measure selected. Minor
graduations appear every ve or ten units, respectively. In horizontal
installations, the scale spans approximately 50 or 100 units from top
to bottom, depending on the unit of measure. In vertical installations,
the scale spans approximately 80 or 160 units from top to bottom,
depending on the unit of measure. The Airspeed Scale will ‘roll’ or
scroll to assist in quick reference as to the increasing or decreasing
nature of the aircraft’s airspeed.
