Sub-system
The cockpit is where a dozen separate systems are integrated into something two people can operate. Displays, flight management, navigation and communication are individually unremarkable technologies held to an extraordinary standard of reliability and certification.
In one sentence
Cockpit avionics are the display, flight management, navigation, surveillance and communication systems that present aircraft state to the crew and execute the planned flight.
Navigation blends several independent sources. Inertial reference units integrate accelerations from a known starting point and drift slowly but cannot be jammed; satellite navigation is precise and can be. Blending them gives a position estimate that is both accurate and robust, which matters more as interference with satellite signals has become a routine operational concern.
The flight management system holds the route, the performance model and the navigation database, and computes the optimal profile. It is the aircraft's planning brain, and the database it depends on is updated on a fixed cycle — a piece of operational infrastructure that is invisible until it is wrong.
Rather than one box per function, modern aircraft run many functions as partitioned applications on shared computing cabinets, with strict guarantees that one partition cannot affect another's timing or memory. It saves weight and wiring, and it moves the difficulty into proving the partitioning is airtight.
Aircraft broadcast their position and receive others', which underpins collision avoidance and increasingly ground surveillance. Separate from that, a traffic collision avoidance system negotiates a resolution directly between two aircraft — a rare example of two safety-critical computers agreeing a manoeuvre without human involvement.
Broadband to the aircraft began as a passenger service and has become operational: real-time engine data, weather, dispatch messaging. That raises questions of segregation between passenger and aircraft networks, and it is why cabin connectivity is now discussed alongside avionics rather than as an amenity.
Technology dependencies are solved by engineering; supply dependencies are solved by building something, which takes years.
Cockpit hardware must survive temperature, vibration and decades of support, from a small qualified supplier base.
Foundry vs IDMRoutes and procedures depend on a maintained database and on airspace rules that define required navigation performance.
Satellite positioning is precise and jammable, so inertial and ground-based sources remain part of the architecture.
Satellite constellationsDisplays, flight management and surveillance functions are developed to assurance levels set by their failure effect, and the evidence package is what allows the equipment to be fitted at all.

What each company supplies at this step, and — where a public figure exists — its share of this specific market — with what that share measures, the period it covers and who published it. Some rows also show the company’s own reported revenue for the segment covering this step, which is a different thing: it says how much this business matters to that company, not how much of the market it holds. Not a ranking and not a recommendation.

Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
