The Aircraft Communications Addressing and Reporting Systems (ACARS), in general, is not set up to "broadcast continually" flight parameters. There are some carriers who use some automatic processing to generate reports at certain times (e.g. EGT over heat, hard landing), but these are very much isolated snapshots. Sorry to be nitpicky, but this is one area I'm familiar with in which mis-information abounds. ed -------- Ed Hahn | email@example.com | (703) 883-5988 -------- The above comment reflects the opinions of the author, and does not constitute endorsement or implied warranty by the MITRE Corporation.
