The Boeing 717 is a twin-engine, single-aisle jet airliner originally developed by McDonnell Douglas as the MD-95 and renamed after its merger with Boeing in 1997. The type entered service in 1999 and was built until 2006. Its cockpit altitude alerting system sounds a chime as the jet nears the altitude selected by the crew, a standard safety prompt in modern airliners. Flight simulator and aviation enthusiasts later isolated the short warning tone, sharing it online for realistic cockpit edits, training videos and aviation-themed memes.
About this sound
The Boeing 717 altitude alarm is a short cockpit warning chime from the aircraft, used in aviation edits, flight simulator clips and meme videos for alerts.
This is the sharp altitude alert chime heard in the Boeing 717 cockpit when the aircraft approaches a selected altitude. It is a clean, repetitive electronic warning tone, urgent without being harsh, that instantly signals a pilot prompt or system reminder. The short burst cuts through cabin noise and other audio, which makes it easy to recognize even in a busy edit. Listeners associate it with focus, precision and a sudden need to pay attention, so a single play can turn an ordinary moment into a mock cockpit emergency or checklist moment.
