NOTE 16. Removed at Revision: 6
NOTE 17. The engine is approved for installation in Normal and Utility aircraft categories only.
NOTE 18. The electronic control unit must not be installed in a dedicated fire zone. The installation conditions are
defined in the applicable Engine Installation Manual.
NOTE 19. The software of the ECU has been validated according to DO 178 B, level C.
NOTE 20. The operating/starting envelope is provided in the applicable Engine Installation Manual.
NOTE 21. A suffix may be added to the SR305-230 basic engine model number on the engine nameplate to identify
minor variations in the engine configuration, installation components, or differences peculiar to aircraft
requirements as follows:
1. SR305-230-1 – Same as the SR305-230 except the SR305-230-1 incorporate modifications that increase
the EMI/lightning protection levels. (See note 22 for levels). The -1 suffix may also be added to
existing engines by incorporation of SMA SB SB-01-76-002. The -1 configuration level is required for
U.S. Installations.
2. SR305-230E has the same level of EMI/lightning protection as the SR305-230-1
3. A Configuration may be added to the SR305-230E data plate with C1 appearing in the
“Configuration” data field to identify a modified starter gear to the Cessna C182 aircraft.
4. A Configuration may be added to the SR305-230E data plate with –MA01, -MA02 or –MA03 to
identify a certificated baseline with minor engine variations in relation to the aircraft application.
NOTE 22. EMI/Lightning: The protection of the engine electronic control system against lightning and
electromagnetic interference has been tested in accordance with DO 160D. The levels of protection are
defined in the applicable Engine Installation Manual.
NOTE 23. The SR305-230 engine model was initially certified with a 2 blade constant speed propeller of 3.5 kg-m2
moment of inertia and 35 kg weight. The list of propellers that are approved for use with the engine is
published in the applicable Engine Installation Manual.
