AVI24C 2-Place Oxygen System for Certified Aircraft

The FAA has approved the Aithre AVI C smart pulse oxygen systems for installation in all Part 23 unpressurized aircraft for 1, 2, 4 and 6 places. Any make, any model, any year, including all unpressurized Beechcraft, Mooney, Cirrus, Cessna, Diamond, Pipers, and every other aircraft certified and flown under Part 23. The simple installation can be performed by any A&P as a minor alteration under NORSEE. 

Importantly, the AVI C system is blanket approved for primary use where oxygen is not actually required by the regulations (e.g., below 12,500 MSL for the pilot). Meaning, the AVI C system is available for use where oxygen should be used (e.g., above 5K MSL at night and above 8K MSL during the day).  

The AVI is first installed smart oxygen system integrated with avionics, the Healthview, iOS, and the Aithre suite of health technology products, delivering smart pulsed oxygen based on factors such as pressure altitude, respiration rate, oximetry, heart rate, and carbon monoxide. 

SYSTEMS OVERVIEW

The AVI system is a complete kit for health and hypoxia management in light aircraft, including the AVI control unit, Healthview, Illyrian oximeters, Aithre Boom Cannulas, Shield carbon monoxide detector, carbon fiber composite bottles, plumbing, ports, mounts, and more.  The system is everything you need for installation to support oxygen delivery in combination with health monitoring of blood oxygen, heart rate, carbon monoixide, oxygen flow, and more.

MORE PERMANENT SEMI-BUILT-IN SYSTEM

AVI is designed as a a more permanent semi-built-in oxygen system. We coined the term semi-built-in to describe the oxygen system because the plumbing is hidden while the bottle is accessible and removable. This is an improvement of the fully-built-in systems because the bottles are easier to fill at small FBOs or to remove when not needed, yet the install is clean, tidy, and professional. However, the AVI is otherwise a fully-built-in system because the control unit is ship powered and the plumbing lines are routed behind paneling and concealed with panel-mounted cannula plugs.  

HEALTHVIEW

The Healthview is the first dedicated avionics system that both controls oxygen delivery and outputs health information, including gauges for blood oxygen, heart rate, respiration rate, flow rate, cabin pressure, cabin temperature, carbon monoxide, and oxygen tank pressure.  

The Healthview features a 240 x 320 pixel TFT resistive touch LCD display with rich and vibrant graphical gauges, enclosed in an ultra-compact aluminum anodized laser etched case. The Healthview is powered by three parallel low energy processors and a wireless communication module for an exciting low heat, low power, high functionality display, using only 150mA of current at 14V. 

The Healthview works as a standalone device for cabin pressure altitude, using an internal barometric pressure sensor. But, the real power lies in the Healthview's ability to dynamically expand to feature any available Aithre device, wirelessly and with or without use of the popular Aithre Connect iOS app.  The Healthview is compatible with all Aithre devices, including the Shield series of carbon monoxide detectors, the Illyrian oximeter, the Meso oxygen pressure, the Metis wingtip temperature/dewpoint sensor, and the AVI and Turbo oxygen systems.  

Additionally, the Healthview controls the built-in AVI with dedicated serial communication, including pulse dosage based on pressure altitude and blood oxygen saturation levels.  For advanced oxygen users, the Healthview provides an auto mode functionality that automatically turns your oxygen on and off on a station-by-station basis, using parameters of pressure altitude, SPO2, heart rate, and carbon monoxide.    

Power requirements are 12-18V and only 150 mA (0.15 A). Dimensions are 90mm x 61mm x 21.5mm and weight is just under 6 ounces.  

OXYGEN DELIVERY

Each station includes an independent pulse circuit.  Simply activate the system and breathe while monitoring the flow and delivery in the Healthview or the Aithre Connect iOS app.  The AVI adjusts dosage automatically based on pressure altitude and provides for further user customization and emergency overrides. 

The pulse system is the first ever to based on MEMS flow measurements as opposed to pressure measurements. This technology provides enhanced inhalation detection plus real-time flow rate determinations and accurate respiration rate feedback. 

To provide smoother oxygen delivery, the AVI delivers each pulse of oxygen as a series of micro bursts with each inhalation. The micro bursts start immediately upon inhalation and extend over the first critical portion of the inhalation cycle. The number and spacing of the microbursts are adjusted in real-time and customized for each inhalation based on respiration length and pressure altitude.

ALTUS WIRELESS PRESSURE GAUGE

The AVI includes the Aithre Altus Meso wireless tank pressure gauge, which allows for monitoring the oxygen pressure remaining while the bottle is out of sight.   Readings from 0-2500 PSI are transmitted to the Healthview and the Aithre Connect iOS app to supplement the analog pressure gauge.  

ILLYRIAN OXIMETERS

The AVI system includes two Illyrian II oximeters for pilot and co-pilot.  The Illyrian wearable oximeter provides continuous real-time SPO2 and heart rate information to the Healthview and to the Aithre Connect iOS app.  Advanced features include head movement and cabin altitude monitoring with haptic vibration feedback.  

AITHRE BOOM CANNULAS

While the AVI system includes two silicone cannulas, the AVI system additionally includes two Aithre Boom Cannulas to make oxygen delivery safer and more comfortable.  The Boom Cannula features a low profile aluminum anodized swivel adapter and an articulating boom arm, make oxygen delivery as easy and convenient as talking on the microphone.  When not in use, the Boom Arm can be pushed or swiveled up and out of the way and can be easily recharged with a new nasal arm after extended periods of use.

AITHRE SHIELD CARBON MONOXIDE DETECTOR

No oxygen system is complete without the Aithre Shield carbon monoxide detector, so the AVI system includes either the Shield EX 3.0 (experimental) or eDOT 5.0 (certified).  The Shield CO detectors offer superior 10 year no recalibration service with sensitivity below 10 ppm and responsiveness of under 60 seconds.   

BACKUP COMPOSITE BOTTLE

The system includes a standalone 47L carbon fiber composite bottle with a fixed flow regulator that outputs approximately 0.5 LPM for 2 hrs.  This handheld bottle is designed to supply a simple independent flow of oxygen for pilot use in the event of any system failure or leakage. The bottle can be stowed and secured in a flight bag or seat back pocket for additional peace of mind during flight.
