- Here's a story from the November, 1992 issue of {Callback}, the
- monthly newsletter published by NASA's Aviation Safety Reporting
- System (ASRS).
-
- "Dialing Dillies"
-
- Pay telephones (Airfones) are being installed in increasing numbers
- for passenger use on commercial aircraft. A recent ASRS report
- highlights one airfone use that we're sure aircraft operators never
- anticipated:
-
- After takeoff, crew noted ... no transponder received on left or right
- by ATC and TCAS was inoperative. While passing upwards through FL240
- right pack trip "off" light illuminated, but reset was impossible
- using irregular checklist. This meant loss of pressurization
- capacity. At FL300 loss of second pack was indicated by the left pack
- trip "off" light -- also not resettable. Captain directed First
- Officer to use oxygen masks and initiate emergency descent. ATC
- cleared aircraft to to FL240, then 15,000 feet, then 10,000 feet
- enroute back to airport. Cabin pressurization reached 9500 feet but
- cabin oxygen masks never actuated ...
-
- This flight was in sunny, dry conditions with no loss of controls or
- engines ... [Crew later discovered that] a passenger in first class
- used airfone to call 911, Highway Patrol, and report aircraft out of
- control and in danger of hitting mountain. In fact, aircraft was
- never in danger of hitting anything, and except for initial pushover
- of nose and actuation of speed brake to begin descent, operations were
- mostly normal.
-
- -----------------
-
- For the benefit of our international readers, 911 is an all-purpose
- emergency telephone number used in the U.S. for contacting
- ground-based emergency services such as fire and rescue, police and
- highway patrol, ambulance services, and other emergency services.
- Some days you just can't win!
