1.1) Electromagnetic compatibility (EMC/EMI)
Electromagnet-
ic interference
Electromagnetic interference (EMI) and lightning
The engine complies with EMI and lightning requirements as per DO-
160C, sections 18, 20-22 as detailed in the following paragraphs.
Emission Emission
Conductive radio interference:
Narrowband and broadband emissions meet RTCA DO160C Section 21-2
Cat. B (AZ) requirements except in the frequency range of 150 kHz-2 MHz
where emissions are up to 20 dB higher than allowable limits.
Radiated radio interference:
Narrowband and broadband emissions meet RTCA DO160C Section 22,
item 21-6 and 21-7, Cat. B requirements except in the frequency range of
190 kHz-2 MHz where emissions are up to 35 dB higher than allowable
limits.
NOTE: Consult the aircraft manufacturer if further interpretation is
needed. The exceeded limits do not affect the operation of
the engine.
Electromagnet-
ic compatibility
Electromagnetic compatibility (EMC)
The engine complies with the electromagnetic interference and lightning
strike requirements of DO-160C, section 18, 20-22 and IEC 801-2.
The following EMC tests have been carried out:
- Radio frequency (RF) sensitivity (conducted)
- Radio frequency (RF) sensitivity (radiated)
- Audio frequency sensitivity
- Lightning strike sensitivity
- Conducted radio frequency (RF) interference
- Radiated radio frequency (RF) interference
