§The Electronic Flight Bag (EFB) Library

The EFB Library is the foundation for flight planning applications, providing functionality to plan a flight and get navigational aids in-flight.

§Overview

At the core of the EFB is the FMS. It holds the navigation data, route and delegates the flight planning. The following example shows the simplest planning:

use efb::prelude::*;

// create the FMS
let mut fms = FMS::new();

// Read navigation data from ARINC 424 records. Here we have the two airports
// EDDH (Hamburg) with the runway 33 and EDHF (Itzehoe) with runway 20.
let records = r#"SEURP EDDHEDA        0        N N53374900E009591762E002000053                   P    MWGE    HAMBURG                       356462409
