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.

Specifications

• Altimeter range: 0 to 20K feet (will not show negative altitude values, nor values above 20,000 feet).
• Pressure Alarm: Preset at 10,000 feet. User adjustable.
• Dimmable for use in low light.
• Aural alarm when pressure alarm value is exceeded.
• Visual alarm appears on screen when pressure alarm value is exceeded.
• Altimeter display type: analog dual needle representation supplemented by digital value.
• VSI display type: analog single needle supplemented by digital value.
• Kollsman window: digital. (This allows fine-tuning the altitude to match local barometric variation and is not used when monitoring cabin pressure altitude.)
