PITCH ADJ to set the Aircraft Reference Symbol to a zero pitch mark for level-flight may
result in improper EFD alignment. If the level flight level zero pitch reference needs
adjustment, proceed in accordance with the ATTITUDE REF SYMBOL ADJ procedure
described below.
NOTE: Once the EFD is installed and properly aligned, the Aircraft Reference Symbol’s level-flight
pitch attitude indication changes with speed and aircraft loading and cannot be adjusted by
the pilot. See 14CFR 23.1303(f). See ATTITUDE REF SYMBOL ADJ adjustment to determine if
further action is required.
Adjust the PANEL TILT PITCH ADJ value using one of the two methods shown below.
Method 1 — Using an Inclinometer
Using an inclinometer and the aircraft leveling indices, measure the offset angle in
degrees (±0.5°), from aircraft level. This reading should be taken when a technician is
seated in the cockpit since the angle could shift when the technician boards the
aircraft. This measurement will be entered in the EFD1000 as CORRECTED PITCH
ATTITUDE. Nose high is + degrees.

1)
Set the ATTITUDE REF SYMBOL ADJ to 0.0º.
2)
Press the PANEL TILT PITCH ADJ line select key and use the bottom right
knob to enter a value for PANEL TILT PITCH ADJ that results in the
CORRECTED PITCH ATTITUDE (Figure 10-4) equaling the value read on the
inclinometer. It may also be set to the amount of panel tilt as determined
through measurement.
3)
Press the PANEL TILT PITCH ADJ line select key.
Method 2 – Leveling the Aircraft
Level the airplane in pitch in accordance with the aircraft manufacturer’s procedure.
Then change the PANEL TILT PITCH ADJ adjustment to make the CORRECTED PITCH
ATTITUDE equal to 0.0°.
1)
Level the aircraft in pitch using the aircraft manufacturer’s procedure.

2)
Set the ATTITUDE REF SYMBOL ADJ to 0.0º.
3)
Press the PANEL TILT PITCH ADJ line select key and use the bottom right
knob to enter a value for PANEL TILT PITCH ADJ that will result in the
CORRECTED PITCH ATTITUDE equaling 0.0º.
4)
Press the PANEL TILT PITCH ADJ line select key.
CORRECTED PITCH ATTITUDE: 0.0°
CORRECTED ROLL ATTITUDE: 0.0°
