C. Temperature Profile
(1) In application mode, the SDU maintains a temperature profile histogram in non-volatile
memory which is updated every minute.
(2) The temperature profile histogram has contiguous bins of 5˚C (41˚F) width to cover the
operating temperature range between -55˚C (-67˚F) and +125˚C (257˚F) with:
(a) all temperature measurements below -55˚C (-67˚F) being captured in the bin for
-50 to -55˚C (-58˚F to -67˚F).
(b) all temperature measurements above +125˚C (257˚F) being captured in the bin
for +120 to +125˚C (248˚F to 257˚F).
D. AES ID
(1) The SDU configures the Safety Voice and ACARS Data services using the received 24-
bit AES ID (ICAO address), obtained from the ORT identified source.
