Approval Required/Authorized Use NOTE-1To determine equipment approvals and limitations, refer to the AFM, AFM supplements, or pilot guides. 2Requires verification of data for correctness if database is expired. 3Requires current database or verification that ... procedure has not been amended since the expiration of the database. 4VFR and hand-held GPS systems are not authorized for IFR navigation, instrument approaches, or as a primary instrument flight reference. During IFR operations they may be considered only…

filing a flight plan or in aircraft/ATC communications. Use current phraseology (e.g., facility name, radial, distance) to describe these fixes. Figure 2-55. Computer navigation fix. Many of the RNAV systems available today make it all too easy to forget ... using, for example, incomplete information, unloadable procedures, complex procedures, and database storage limitations. Required Navigation Performance Required navigation performance (RNP) is RNAV with onboard navigation monitoring and alerting. RNP is also a statement of navigation performance necessary for operation within…

systems onboard the aircraft. In general, these types of unintentional interference are localized and intermittent. Of greater and growing concern is the intentional and unauthorized interference of GPS signals by persons using “jammers” or “spoofers” to disrupt air navigation ... impacts of GPS jamming and/or spoofing, which include, but are not limited to: 1. Inability to use GPS for navigation. 2. Inability to use hybrid GPS inertial systems for navigation. 3. Loss of, or degraded, performance-based navigation (PBN) capability…

common use. Short-range radio systems usually did not provide area navigation (RNAV) capability. Long-range systems were only capable of en route pointto-point navigation between manually entered waypoints described as longitude and latitude coordinates, with typical systems containing ... limited number of waypoints. The laborious process of manually entering cryptic latitude and longitude data for each flight waypoint created high crew workloads and frequently resulted in incorrect data entry. The requirement of a separate control panel for each long…
- Chapter 6: Airborne Navigation Databases › Operational Limitations of Airborne Navigation Databases
Navigation Databases Understanding the capabilities and limitations of the navigation systems installed in an aircraft is one of the pilot’s biggest concerns for IFR flight. Considering the vast number of RNAV systems and pilot interfaces available today ... issues when using airborne navigation databases. Although modern avionics can provide precise guidance throughout all phases of flight, including complex departures and arrivals, not all systems have the same capabilities. RNAV equipment installed in some aircraft is limited to direct…

detected a potential error that exceeds the limit for the current phase of flight. Without RAIM capability, the pilot has no assurance of the accuracy of the GPS position. Aircraft using GPS navigation equipment under IFR for domestic en route ... routes must also be operational. Active monitoring of alternative navigation equipment is not required if the GPS receiver uses RAIM for integrity monitoring. Active monitoring of an alternate means of navigation is required when the RAIM capability…
