There are many threads over the years regarding in flight GPS units, which airlines allow and which do not, whether they can be used below 10,000 feet etc. I would like to discuss simply the concept of in flight security as relates to GPS units.

After the events of 9/11/01, I have always been somewhat amazed that many carriers continued to allow the use of GPS units in flight. There is certainly a high tactical value in allowing someone who intends evil to know their exact location. And even more so to a device that can be pre-programmed to track to any precise location from the current position.

This may sound like a nervous old lady, but I have even wondered whether the ever-present moving maps that are aboard so many aircraft provide too much information to those that have evil intents!
