Gas detectors for aerospace applications cover electrochemical, catalytic bead, non-dispersive infrared (NDIR), and solid-state semiconductor sensing technologies used to detect and measure toxic, combustible, and oxygen-deficient atmospheres within aircraft cabins, cargo bays, engine bays, and ground-support environments, encompassing CO, COâ‚‚, ozone, and hydrocarbon gas detection in accordance with airworthiness requirements.
How many distinct aircraft programs each supplier in this area is linked to in our database — a proxy for how widely established a company is across the industry. Bars are relative to the top-ranked supplier.
Whether supply here is concentrated in a few big players or spread across many. Top-5 share is the portion of all program links held by the five largest suppliers. HHI (Herfindahl–Hirschman Index) runs 0–10,000: under ~1,500 is competitive, over ~2,500 is concentrated.
