1 AIRTEC 2013 SENSORS & TESTING (ASAT12) Future Roadmap for Inertial Sensors Used in Aviation Applications 6 th November, 2013

2 Inertial Sensor Applications Attitude & Heading (AHRS)[$30k] Standby Instrument [$20k] Antenna Stabilisation [$10k] Flight Control [$30k] Damping & Stabilisation [$10k] Inertial Navigation (IRS) [$300k] HUMS [$10k] Primary Aircraft Function [~$400k] Secondary Function [~$20k] 1,000 aircraft/yr = $0.4bn pa (Civil transport market only) 2

3 Inertial Sensor Penetration 100% Penetration High Penetration Low Penetration 3

4 Supply Chain Quartz FOG RLG 4

5 Technology Trends Civil Transport This sector is slow and reluctant to change. Competition is limited and the barriers to entry are high. FOG is displacing RLG, but will overtake both and be the technology of choice within 5-10 years (excluding IN) 3x $100k <0.01 /hr <10µg IMU IRS INS RLG $30k <0.1 /hr <1mg IMU AHRS FOG RLG Resonant $20k <10 /hr <1mg IMU EFIS RLG FOG Resonant $5k Rate Sensor <50 /hr Quartz $5k Rate Sensor <50 /hr Quartz 5

6 Technology Trends Bizjet The tier 1 suppliers in this sector are not as entrenched and are finding novel ways to overcome the challenges (performance & standards) to take advantage of the benefits of converting to $20k <10 /hr <1mg IMU AHRS FOG Resonant $12k <10 /hr <1mg IMU EFIS FOG Quartz $3k Rate Sensor <50 /hr Quartz $3k Rate Sensor <50 /hr Quartz 6

7 Technology Trends General Aviation GA is the market innovator and has been the Early Adopter. New companies have sprung up creating all-new -based avionics. With no preconceptions and fewer obstacles (performance & standards) has become the standard in this market. <$10k <50 /hr <10mg IMU AHRS <$10k <50 /hr <10mg IMU EFIS <50 /hr Rate Sensor <50 /hr Rate Sensor 7

8 Analysis Established inertial technologies have reached their apogee Minimal scope for change (improvement) is in the ascendancy Its low-cost and reliability credentials are proven. There is still much scope for improvement in performance. Error mechanisms and solutions continue to evolve. Designs and processes are constantly improving. Competition is healthy (warning -not all are the same) 8

9 Analysis In all but navigation, is today capable of displacing the entrenched technologies (and supply chains) General Aviation is the Early Adopter, and new avionics businesses and products have burgeoned on the back of The smaller passenger transport (Bizjetand Helicopter) tier 1 suppliers are not vertically integrated, and are overcoming the additional hurdles to reach the benefits of using The civil transport sector has a reluctance to change. The supply chain has limited competition and is vertically integrated, represents a threat as well as an opportunity 9

10 Drivers and Challenges Drivers for the march to are. Primary-cost, size and weight reduction (in the sensors, but also through integration IMU) Secondary improved reliability from reduced complexity Challenges are Performance achieving the performance goals (<0.1 /hr) without compromising the primary drivers Standards QA, hardware, firmware and software design requirements Supply chain there is reluctance to change in the civil transport sector 10
