Installation

I'm using go mod so examples will be using it, you can install this package via Go modules.

go get github.com/mrlm-net/simbrief

Requirements:

• Go 1.21 or higher • Internet connection (for SimBrief API access) • Web browser (for flight plan generation authentication)

Usage

package main

import (
    "fmt"
    "log"

    "github.com/mrlm-net/simbrief/pkg/client"
    "github.com/mrlm-net/simbrief/pkg/types"
)

func main() {
    // Create a new SimBrief client
    simbrief := client.NewClient()

    // Create a basic flight plan request
    request := &types.FlightPlanRequest{
        Origin:      "KJFK",  // New York JFK
        Destination: "KLAX",  // Los Angeles LAX
        Aircraft:    "B38M",  // Boeing 737 MAX 8
    }

    // Generate flight plan URL (actual generation requires browser authentication)
    planURL := simbrief.GenerateFlightPlanURL(request)
    fmt.Printf("Flight plan URL: %s\n", planURL)

    // Get supported aircraft types
    options, err := simbrief.GetSupportedOptions()
    if err != nil {
        log.Fatal("Failed to get aircraft options:", err)
    }

    fmt.Printf("Found %d aircraft types available\n", len(options.Aircraft))
}

Examples

The examples/ directory contains practical demonstrations of SimBrief features:

Example	Description	Features
basic	Basic flight plan operations and data retrieval	Get supported aircraft, Fetch existing plans, Basic API usage
advanced	Complete flight planning with custom parameters	Custom aircraft data, Advanced routing, Detailed fuel planning

Run any example:

cd examples/basic
go run main.go

API Reference

Core Components

Client Creation

client := client.NewClient()                      // Create new client
client := client.NewClientWithConfig(...)        // Create with custom config

Flight Plan Generation

request := &types.FlightPlanRequest{
    Origin:      "KJFK",     // Origin airport ICAO
    Destination: "KLAX",     // Destination airport ICAO
    Aircraft:    "B38M",     // Aircraft type
    Route:       "DCT",      // Flight route
}

// Generate URL for browser-based flight plan creation
planURL := client.GenerateFlightPlanURL(request)

Data Retrieval

// Get supported aircraft and layouts
options, err := client.GetSupportedOptions()

// Fetch existing flight plan by user ID
flightPlan, err := client.GetFlightPlanByUserID("user_id")

// Get flight plan by username  
flightPlan, err := client.GetFlightPlanByUsername("username")

// Or choose the format: JSON v2 (json=v2) or XML; both decode the same way
flightPlan, err := client.GetFlightPlan(&types.FetchRequest{UserID: "user_id", JSON: true})

OFP Data

types.FlightPlanResponse decodes the OFP from JSON v2 and from XML (root element <OFP>). Numeric values are types.Number: the raw text SimBrief sends ("0365", "05000", ".57") with Int(), Float() and Bool() helpers. Time values stay strings (JSON v2: ISO 8601 and HH:MM:SS, XML: Unix seconds and seconds).

fmt.Println(flightPlan.ATC.Callsign)                          // "CEF007"
fmt.Println(flightPlan.ATC.InitialAltUnit, flightPlan.ATC.InitialAlt) // "F" "150"
fmt.Println(flightPlan.General.STARIdent)                     // "BEKV1Q"
fmt.Println(flightPlan.General.InitialAltitude.Int())         // 15000
fmt.Println(flightPlan.Origin.ICAO, flightPlan.Origin.Runway) // "LKPR" "06"
fmt.Println(flightPlan.Origin.TransAlt.Int())                 // 5000
fmt.Println(flightPlan.Aircraft.ICAOCode)                     // "A319"

for _, altn := range flightPlan.Alternates {
    fmt.Println(altn.ICAO, altn.Runway, altn.Burn.Int())
}
for _, fix := range flightPlan.NavLog {
    fmt.Println(fix.Ident, fix.ViaAirway, fix.AltitudeFeet.Int(), fix.IsSIDSTAR.Bool())
}

Custom Configuration

httpClient := &http.Client{Timeout: 60 * time.Second}
client := client.NewClientWithConfig("https://api.simbrief.com", httpClient)

Debugging

Enable detailed HTTP logging and error information:

Environment Variables:

export SIMBRIEF_DEBUG=true          # Enable debug logging
export SIMBRIEF_USER_ID=your_id     # Set user ID for examples

Common issues:

• Network connectivity: Ensure stable internet connection for API access • Invalid aircraft code: Verify aircraft ICAO codes using GetSupportedOptions() • Route validation: Check route format against SimBrief documentation • Rate limiting: SimBrief may rate limit requests; implement appropriate delays

API Documentation: SimBrief API Docs

Advanced Usage
