Overview

center> **NOTE FAA APPROVED - FOR USE IN EXPERIMENTAL AIRCRAFT ONLY** SafeAlt is a Portable Altimeter designed for use by pilots and passengers to increase safety of flight in three scenarios. For general aviation pilots, it provides a backup to panel-mounted altimeters and VSI gauges in an easy to use, USB rechargeable, portable device. For corporate pilots in pressurized aircraft, it provides a visual and aural alarm if altitude de-pressurization occurs. This might save lives. For passengers on commercial aircraft, it provides a visual and aural alarm if cabin altitude slowly exceeds a set value (indicating a failure of the aircraft to pressurize) or rapid decompression occurs (also indicating a pressure failure). Furthermore, it provides a reading of pressure altitude within the cabin, which is a proxy for flying comfort. The latest commercial aircraft designs have better, or lower, pressure altitude while flying.

Features

• SafeAlt runs for hours off an internal USB chargeable battery and uses an extraordinarily accurate solid-state pressure sensor.
• SafeAlt is a self-contained, portable device. The altitude sensor is internal and uses ultra-reliable MEMS technology. A USB charging port and switch are on the side. Buttons on the bottom can be used to exactly match the local pressure setting but aren’t needed for tracking cabin pressure inside an aircraft.
• Of course, it is also an excellent backup to panel-based altimeters and VSI gauges for any general aviation pilot. An optional Adapter Ring is available for mounting in a 3 1/8” standard panel cutout.
