Lightspeed App2.3.0 - App Store

A companion app to the Lightspeed Delta Zulu ANR headset, the Lightspeed app for iOS features an array of integrated features to keep pilots and passengers safer during flight.

Track CO Sensors for Safer Flying

The Lightspeed app allows pilots to check the CO levels in the aircraft during flight, using a CO sensor built right into the Lightspeed Delta Zulu headset.

The sensor provides real-time smart alerts via the proprietary Kanari(TM) smart alert technology. Historical data can be stored, reviewed, and analyzed after use and during the flight(s).
Personalize Audio with HearingEQity(TM)

The Lightspeed app introduces a built-in audio equalization system called HearingEQity(TM) designed to compensate for individual hearing loss.

Through an automated 12-frequency hearing test taken through the app, HearingEQity sets the hearing level in each ear in a variety of frequency bands of the Lightspeed Delta Zulu headset to create an individual hearing profile and compensate for any hearing variations between ears.

Record Conversations, Archive Flight Recordings, and More...

The Lightspeed App allows pilots to record radio conversations, playback transmissions, draw diagrams, and archive flight recordings for post-flight briefings and training.
