What are minimum cargo temperatures for trans-oceanic flights?

Question

We are experiencing loss of memory on EEPROMs in shipments to Europe/Asia specifically, and I am wondering if higher altitudes/lower temperatures in trans-oceanic freight shipment are a possible issue.

Answer 1

temperature and pressure stays constant in all cargo holds whether on an all cargo plane or otherwise : 10-15 degrees Celsius and pressure same of that you would find at 7,000 or 8,000 feet. It is unlikely that your EEPROMS were affected by altitude or temperature

Did you consider moisture and static? Or how about magnetized metal inside the airplane? ( like what a magnet could do to data disks.)

I don't think X-rays do anything to them because my ipods, laptops etc all go through the Xray machine.

Thinking specifically about to Europe and Asia flights....hmmm.... nothing different comes to mind. Flights to there are just like flights o anywhere else in terms of altitude, procedures etc.

Maybe the security there uses something we don't use here to screen cargo?

Answer 2

Generally speaking, the temperature in the cargo holds of aircraft do not fall below 45 degrees. The altitude should not have any effect either, as the inside altitude is usually about 7-8000 feet, the same as being in Albuquerque.

What do x-rays do to EEPROMs? Is this happening to many of these, or just a few? Is there a pattern? Are these staying inside your company, or are these being delivered to customers?
