Integrated Flight Information System – (IFIS)

The IFIS system in the Pro Line 21 modernization package gives you the latest options in electronic charts, weather, and enhanced navigation maps. The IFIS integrates Rockwell Collins’ patented Chartlink system that automatically loads the appropriate electronic charts, including alternates, as the departure and destination airports are entered into the FMS. This decreases heads downtime and crew workload and increases crew efficiency. Key Benefits

  • Electronic Charts
  • Graphical Weather (Universal Weather for Aircraft Equipped with VHF Data Link, XM Optional)
  • Enhanced Navigation Maps

WAAS GPS-4000s

The WAAS-enabled GPS-4000S allows pilots to utilize GPS as their primary means of navigation. This means you can utilize the GPS system without reliance on other navigation for en-route operations and approaches, such as RNAV (GPS) approaches. With the GPS-4000S, you can also take advantage of Localizer Performance with Vertical guidance (LPV) approaches if your FMS is equipped with the LPV function. Key Benefits

  • Primary Means of Navigation
  • Streamlined Pre-Flight Procedures
  • More Options for Alternate Airports


LPV approaches are an essential upgrade for your aircraft that lower Decision Altitudes on RNAV approaches to as low as 200 feet with 1/2 mile of visibility. Paired with a WAAS-GPS, this approach can get you into over 3,300 airports in the US and over 170 in Canada, with more being added every year. This can get you closer to your destination with more variability in conditions. Key Benefits

  • Land More Places, More Often
  • New Vertically-Guided Approaches to Airports Not Equipped with ILS Approach Systems
  • Additional Backup for ILS


All aircraft flying in controlled US airspace are required to meet ADS-B Out requirements. ADS-B technology enables aircraft to continuously broadcast GPS including aircraft position, heading, and velocity, even in areas that have no traditional radar facilities. This mandate is intended to increase safety while decreasing separation minimums between aircraft. The Pro Line 21 Modernization package meets all ADS-B mandates.
