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…

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…

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…

use it in VFR/IFR navigation. It does differ significantly from conventional, ground-based electronic navigation and awareness of those differences is important. Awareness of equipment approvals and limitations is critical to the safety of flight. The GPS navigation system broadcasts…
- Chapter 9: Navigation Systems › Traditional Navigation Systems › Operational Errors of ADF
read in combination before any interpretation is made. 9. Failure to understand the limitations of the ADF and the factors that affect its use. 10. Overcontrolling track corrections close to the station (chasing the ADF needle) due to failure ... recognize station approach. Very High Frequency Omnidirectional Range (VOR) VOR is the primary navigational aid (NAVAID) used by civil aviation in the National Airspace System (NAS). The VOR ground station is oriented to magnetic north and transmits azimuth information…
- 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…
