Software:
RTCA DO-178B ......................... Level C
Environmental:
RTCA DO-160E.......................... See Environmental Qualification Form Section 13
European Technical Standard Order:
ETSO-C2d Type B, -C3d Type II, -C4c, -C6d, -C8d Type B, -C10b (-1600 to 51,000 feet),
-C106, -C113, Type I.
List of ETSO deviations:
1. Use of EUROCAE ED-14E/RTCA DO-160E instead of ED-14D/DO-160D change 3.
2. Deviate from ETSO-C2d to eliminate the requirement 3.2.3 in SAE AS 8019 that requires "the instrument
face to be marked with 'Airspeed' or 'IAS' and also with the applicable units of measure."
3. Deviate from ETSO-C4c 3.1.2 and SAE Aerospace Standard AS 8001 to use RTCA DO-160D instead of
RTCA DO-138 as the standard for Environmental Conditions and Test Procedures for Airborne
Equipment.
4. Deviate from SAE AS 392C Section 4.2.4 to not display ALTITUDE or ALT next to the tape indicating
altitude.
5. Deviate from ETSO-C10b 3.1.1 to use RTCA DO-160D instead of SAE AS 392C as the standard for
Environmental Conditions and Test Procedures for Airborne Equipment.
6. Deviate from SAE AS 392C Section 4.1. In lieu of a pointer moving in a clockwise direction, there is a
display of a vertical altitude scale/tape with digital readout. The altitude display comports with SAE ARP
4102-7 Appendix A Symbols 39 and 40.

2.1.5 Design Eye Viewing Envelope
The following information defines the viewing envelope within which the EFD1000
complies with the Equipment standards:
Minimum and maximum distance from the center of the EFD1000 display surface:
10 inches (25.4 cm) minimum to 45 inches (114.3 cm) maximum
Total viewing angles:
From -30º to +30º (left/right), and +30º to -30º (top/bottom) perpendicular to the
EFD1000 front glass surface.
