Altitude tape, digital readout, and VSI
The altitude tape scrolls beneath the altitude digital readout and arrow. The digital readout’s digits scroll up
and down, simulating an analog altimeter and giving a sense of the direction of movement. Thousands of
feet are displayed usin g lar ge numbers while hund reds of feet are displayed in smaller numbers. The EFIS-
D60 accurately displays altitudes from -1200 to 30,000 ft (-365 to 9144 m).
The graphical Vertical Speed Indicator is located next to the altitude tape. The magenta bar grows in the
direction of – and in proportion to – the rate of climb or descent. The numbers on the scale repr esent
thousands of feet per minute. In the CLUTTR menu, th e VSI scale can be set to display 1000 ft/min, 2000
ft/min, and 4000 ft/min. The 2000 ft/min scale is linear throu ghout the range, while the 1000 ft/min and
4000 ft/min are non-linear as shown on the scale. When set to display 2000 ft/min, the VSI bar is scaled to
indicate a 6-second altitude trend based on its position with relation to the altitude bar. When set to display
4000 ft/min, the VSI bar is scaled to indicate a 6-second trend only up to 1000 ft/min. When set to display
1000 ft/min, the VSI bar is scaled to indicate a 12-second trend up to 500 ft/min.
During the first 30 seconds of operation, the altitude tape and digital readout are not displayed as the unit needs a small
amount of time before altitude measurements are deemed accurate.
Angle of attack (AOA) indicator
The angle of attack indicator – available only with Dynon’s AOA Pitot Probe – displays the aircraft’s current
AOA relative to the stall AOA. The AOA calibration process should result in the lowest angle of attack stall
(usually the “clean” configuration) occurring between the yellow and red lines and the higher angle-of-attack
stall (usually the “dirty” config uration) occurring at the top of the red. As your aircraft’s angle of attack
increases, the bars in the indicator disappear, leaving the empty outline. As your aircraft’s AOA approaches
stall, downward-pointing arrows are left. Depending on your installation and configuration, an audible alarm
