Domain-Specific Language for Aviation Flight Planning and Operations
A specialized programming language designed for aviation professionals, featuring natural syntax for flight operations, built-in aviation calculations, and comprehensive safety validation.
^^ Flight Planning in AirLang MAIN { BRIEFING { AIRCRAFT { Registration: C-GEGL; } FLIGHT { Number: AL120; } ROUTE { Departure: 45.3225, -75.6692; Arrival: 43.6777, -79.6248; } } ENDBRIEFING; LOADSHEET { Distance = AIRPATH; PRINT { "Flight Distance: " + Distance }; } ENDLOADSHEET; } ENDMAIN;
AirLang provides domain-specific abstractions that make flight planning code more readable, maintainable, and safer.
Native support for aircraft identifiers (C-GNBL), flight numbers (AC180), coordinates, and weather data with automatic validation.
Great circle distance (AIRPATH), wind components, fuel calculations, and weight & balance computations integrated into the language.
Compile-time checking of weight limits, fuel capacity, and regulatory constraints to prevent unsafe flight configurations.
Live METAR fetching from AviationWeather.gov API with automatic parsing, wind analysis, and real-time weather data integration.
Block-structured syntax that mirrors standard aviation documentation practices and operational procedures.
Complete 7-phase compiler implementation with aviation-specific optimizations and comprehensive error handling.
Traditional compiler design enhanced with aviation-specific features
