ED Decision 2019/008/R
EVALUATION OF CARGO TRACKING DEVICES
(a) Safety assessment
Further guidance on performing a safety assessment can be found in:
(1) EASA, âCertification specifications and acceptable means of compliance for large aeroplanesâ, CS-25, Book 2, AMC-Subpart F, AMC 25.1309;
(2) EUROCAE/SAE, âGuidelines for development of civil aircraft and systemsâ, ED-79/ARP 4754 (or later revisions); and
(3) SAE, âGuidelines and methods for conducting the safety assessment process on civil airborne systems and equipmentâ, ARP 4761 (or later revisions).
(b) HIRF certification
The type certificate data sheet (TCDS), available on the EASA website for each aircraft model having EASA certification, lists whether the HIRF certification has been performed through a special condition. The operator may contact the type certification holder to gain the necessary information.
(c) Multiple modes of redundancy
Multiple modes of redundancy means that the device is designed with a minimum of two independent means to turn it off completely, turn off the cellular or mobile functions, or a combination of both when airborne. These independent methods should use different sources to identify that the aircraft is in flight, for example, a cargo-tracking device may be designed to sense rapid altitude changes and acceleration to determine when to turn off cellular transmissions. Redundant sources of the same information, such as two vertical accelerometers, should not be considered independent.
