Aviation maintenance (MRO) and flight operations software

Flying and maintaining the aircraft, every check, repair and flight plan

An airliner may fly several flights a day, for 25 years or more. Between flights, engineers check it and sign it off as safe to fly. Every check, repair and replaced part is written down. Software keeps those records, the manuals the engineers work from, and the charts and plans the pilots fly with.

Keeping an aircraft airworthy. An aircraft may fly only if it is airworthy: fit to fly, by the regulator's rules. In India, the regulator is the DGCA, the Directorate General of Civil Aviation.

Every part has a life limit

A part must be replaced after a set number of flying hours, or a set number of cycles. A cycle is one take-off and one landing.

Every job must be recorded

Each inspection, repair and replacement is logged, and the records stay with the aircraft for its whole life.

The records have value

Without complete records, an aircraft can be grounded, and it is worth much less when sold.

Keeping an aircraft airworthy: after each flight, engineers check the aircraft, repair it or replace parts at their life limit, and log every job in records that stay with the aircraft for its whole life.

The industry calls this work MRO: maintenance, repair and overhaul. Airlines do some of it themselves and hire specialist MRO companies for the rest.

The manuals. Aircraft makers publish maintenance manuals that run to thousands of pages. They are updated often, and engineers must always work from the latest version. Software stores the manuals and shows each engineer the right procedure.

The pilot's tools

The electronic flight bag

Pilots used to carry heavy bags of paper charts and manuals. Today they carry a tablet with an app that holds the charts, the flight plan and the weather.

Charts and navigation data

Airports, air routes and landing procedures are updated worldwide on a fixed 28-day cycle, and every aircraft and flight bag must carry the current data.

Simulators

Pilots train, and are tested at regular intervals, in flight simulators: full copies of a cockpit that move and behave like a real aircraft.

Who buys. The buyers are airlines, MRO companies, operators of business jets, air forces and flight schools. It is a small, specialised market, and its work in India is modest.

Every company named here has posted software engineering jobs in India. Famous companies that don't actively hire software engineers in India are left out.

Maintenance records and manuals

Veryon

with engineers in Chennai, sells software through which airlines and other operators track the maintenance, parts and manuals of every aircraft. Veryon has the most job postings in this Market Segment.

Flatirons Solutions

with engineers in Chennai, sells technical documentation systems. Mechanics read the procedures for each job from them.

Flight bags and charts

ForeFlight

with engineers in Bengaluru, makes the electronic flight bag through which pilots plan flights and read charts.

Jeppesen ForeFlight

makes the aeronautical charts and navigation data behind it.

Boeing sold the two businesses in 2025.

Simulators

Acron Aviation

with engineers in Bengaluru, makes pilot simulators and avionics. (More on it in Market Segment 42.5, Upskilling platforms and coding bootcamps, in Industry Vertical 42, Edtech.)

Lufthansa Technik and CAE are not covered in this Market Segment. Sabre Corp., which sells software to airlines, is covered elsewhere. (More on it in Market Segment 29.2, Travel distribution (GDS) and airline software, in Industry Vertical 29, Travel tech.)

The mechanic's assistant.

Aircraft maintenance runs on thousands of pages of manuals and a history of every part. AI models now find the right procedure, predict which part will fail, and draft the paperwork. Regulators still require a human to sign off each job. What changes is how much of the work behind that signature AI does.

That is the software that keeps aircraft flying: maintenance records and manuals for the engineers, and flight bags, charts and simulators for the pilots. It is a small, specialised market, held together by strict rules.
