  • Chapter 13: Aviation Weather Services › Electronic Flight Displays (EFD) /Multi-Function Display (MFD) Weather › NEXRAD Limitations

    Use all appropriate sources of weather information to make in-flight decisions. • Let your fellow pilots know about the limitations of in-cockpit NEXRAD. NEXRAD Abnormalities Although NEXRAD is a compilation of stations across the country, there can be abnormalities…

  • Chapter 5. Air Traffic Procedures › Section 1. Preflight › 5-1-6. Flight Plan - IFR Flights

    established airway and route use, and to provide guidance for planning flights outside of established airways or routes. These areas of airspace are expressed in terms of cylindrical service volumes of specified dimensions called “class limits” or “categories ... assured. To facilitate use of VOR, VORTAC, or TACAN aids, consistent with their operational service volume limits, pilot use of such aids for defining a direct route of flight in controlled airspace should not exceed the following: (a) Operations above…

  • 3 Overview of Aviation Weather Information › 3.2 Use of Aviation Weather Information › 3.2.2 Product Latency

    time on the particular data link information displayed in the cockpit or EFB. The amount of latency may limit the use or application of the information or product. An example of weather information without latency is the wind direction when…

  • Chapter 10. Helicopter Operations › Section 1. Helicopter IFR Operations › 10-1-2. Helicopter Instrument Approaches

    more than 70 KIAS unless otherwise charted. Military RNAV Copter IAPs are limited to no more than 90 KIAS throughout the procedure. Use the published minima; no reductions allowed. NOTE-Obstruction clearance surfaces are based on the aircraft speed identified ... have a VMINI greater than 70 knots; therefore, they cannot meet the 70 knot limitation to conduct these RNAV approaches. Some helicopter autopilots, when used in the “go-around” mode, are programmed with a VYI greater than 70 knots. Therefore…

  • Chapter 4. Air Traffic Control › Section 5. Surveillance Systems › 4-5-6. Traffic Information Service (TIS)

    altitude encoder (Mode C), the altitude and altitude trend “tags” would have been omitted. d. Limitations. 1. TIS is NOT intended to be used as a collision avoidance system and does not relieve the pilot’s responsibility ... visual traffic avoidance, it has some system limitations that must be fully understood to ensure proper use. Many of these limitations are inherent in secondary radar surveillance. In other words, the information provided by TIS will be no better than…
