Placards and Switch Labeling Check

If any placards were replaced or relocated as a result of a display installation, verify the following:
• The font size of the new placard is the same as the old placard it is replacing
• The color of the new placard is identical to the color of the placard it is replacing
• The text on the new placard is identical to the text on the placard it is replacing (it can be arranged
differently as required by space constraints, but the wording must be the same)
• The placard must be legible and not obscured to the pilot by the glareshield, in all flight control
positions, or by any other component in the flight deck
If the new switch labels were added as a result of the GI 275 installation, verify the following:
• The font size and label is legible from the pilot's seat
• The labels are legible in all ambient light conditions. In particular, the labels are legible with
ambient flood lighting in darkness
• The switch label must be legible and not obscured to the pilot by the glareshield, in all flight
control positions, or by any other component to include the switch position
If the GI 275 installation is limited to VFR operation only, and the criteria in Section 2.2 determined a
placard is required, verify the following:
• The text on the placard reads: "AIRCRAFT LIMITED TO VFR"
• The font is at least 0.25 inches high
• The placard is legible from the pilot's seat
If separate EIS annunciators were installed, a placard or label is required. Verify the following:
• The text on the placard reads: "ENGINE"
• The font is at least 0.125 inches high and easily readable with sufficient contrast from the
surroundings
• The text must be displayed in a conspicuous place so that it cannot be obscured to the pilot by the
glareshield or any other component and remains visible in all flight control positions
• The text is legible in all ambient light conditions, particularly with ambient floodlighting in
darkness
Aircraft with an existing Operating Airspeed Placard, which includes information such as maneuvering
speed, landing gear operating speed, and multi-engine aircraft operating speeds, that was relocated as the
result of installation of the GI 275 system must have the new placard installed as close to the airspeed
display as practical.
