Built from real regional airline operations.
AeroNav is flight planning and self-dispatch software for Australian regional, charter and utility operators, built around the operational decisions that determine whether the planned payload remains achievable.
Why AeroNav exists
AeroNav exists to close the gap between early planning, final dispatch and the flight that actually operates.
In lean regional, charter and utility operations, planning a sector can involve several separate workflows: building the route, checking runway performance, estimating fuel and time, assessing TAFs, selecting alternates, reviewing payload and then producing the final OFP.
Each step may be reasonable on its own. But when conservative assumptions are added separately at each stage (runway performance, enroute fuel, temperature, wind, weather interpretation and alternate planning), the margins can compound.
The result is often not just extra planning time. It is payload uncertainty. On temperature-, wind- or runway-limited sectors, overlapping buffers can mean carrying less revenue payload than the aircraft may otherwise have been able to lift under the operator's approved assumptions.
AeroNav is not about removing required safety margins. It is about applying approved data and operator rules consistently, so unnecessary overlapping assumptions do not accumulate unnoticed.
AeroNav was built to make those decisions visible in one workflow: aircraft-specific regulated take-off weight calculations, enroute planning from approved performance data, forecast-aware fuel and time calculations, and weather/alternate decision support that assesses the TAFs against the flight being planned.
The goal is simple: earlier planning, clearer exceptions, more predictable payloads and consistent OFPs without ad hoc buffer-on-buffer accumulation.

Will is an Airbus A220 Captain and senior flight-operations leader, with Chief Pilot and Head of Flight Operations experience across Australian and Papua New Guinea regional aviation. Alongside his operational career, he is a software engineer focused on flight planning, aircraft performance and operational systems automation.
His flying background includes the ATR 42/72, Dash 8, DHC-6 Twin Otter and Britten-Norman BN-2, including PNG mountain airstrip operations involving steep slopes, short runway lengths and high-elevation aerodromes. He is also a Flight Instructor and Examiner.
AeroNav reflects that combination: practical airline operations, aircraft performance, regulatory decision-making and software engineering brought together in one dispatch workflow, built for operators that need fuel, payload, weather, alternates and runway performance assessed together.
How AeroNav is built
AeroNav is focused on lean regional, charter and utility operations, but its underlying engine is not limited to one aircraft type.
It is built on a universal precision planning architecture: a core engine designed to support aircraft ranging from B737-class jets to regional turboprops, utility aircraft and piston twins. By changing the operator-approved aircraft data, performance model, fuel policy, ruleset and operating assumptions, the same framework can support mixed fleets without separate calculators or disconnected workflows.
That architecture is guided by four operating principles.
Aircraft-specific planning
Plans should reflect the aircraft, performance data and operating assumptions approved for the operator.
Weather-aware decisions
TAFs, winds, temperature and operational conditions should flow through fuel, payload, alternates and release decisions.
Transparent assumptions
Crews and operations teams should be able to see why a plan changed, what triggered an exception and what assumption drove the result.
Lean dispatch capability
Regional, charter and utility operators should have access to serious dispatch tools without major-airline overhead.
