ENGINE MANUAL
IAE50R – AA
19.6 Electronic Components Capability
The electronic components have been tested to meet environmental requirements as
specified in RTCA 160 C/D. The following information is to assist the engine installer.
To show that the ECU is not susceptible to failure when exposed to external electrical or
environmental effects, a number of tests were performed.
19.6.1 Electrical tests
Power Input Test DO-160C, Section 16 Cat Z.
The two power supply lines were connected to independent
power sources. One supply line was always powered.
Voltage Spike Test DO-160C, Section 17 Cat A.
Audio Frequency Conducted Susceptibility DO-160C, Section 18 Cat Z.
Induced Signal Susceptibility Test DO-160C, Section 19 Cat Z.
Conducted RF Susceptibility Test DO-160D, Section 20.4 Cat Y
Radiated RF Susceptibility Test DO-160C/D, Section 20.5 Cat Y
Emission of Radio Frequency Energy Conducted DO-160C, Section 21.4
Cable Bundl to ECU Cat Z and A
Power Lines to ECU Narrowband Cat Z and A
Broadband Cat B
Broadband not required in
Do-160D
Emission of Radio Frequency Energy Radiated DO-160C, Section 21.5
Cat A, B and Z
Lightening Induced Transient Susceptibility DO-160C, Section 22 Cat Z3
Magnetic Effect DO-160C, Section 15,
Equipment Class Z
The compass safe distance for 1° deflection was established as:
0° at 5cm (EUT X-axis)
0,5° at 8cm (EUT Y-axis)
0,5° at 10cm (EUT Z-axis)
