16. Do remember that vivid and frequent lightning indicates the chance of a extreme thunderstorm. 13.
Ten minute most and minimum RVR values for the designated RVR runway are reported within the physique of the aviation climate report when the prevailing visibility is lower than one mile and/or the RVR is 6,000 ft or less. ATCTs report RVR when the prevailing visibility is 1 mile or much less and/or the RVR is 6,000 feet or much less. For apparent reasons of security, an IFR pilot should not deviate from the course or altitude or flight degree and not utilizing a proper ATC clearance. When weather conditions encountered are so severe that a direct deviation is set to be necessary and time won’t permit approval by ATC, the pilot’s emergency authority may be exercised.

An instance would be a NEXRAD radar composite/mosaic map, which has been modified by changing the scaling decision. The methodology of assigning reflectivity values to the resultant image elements ought to be described within the vendor’s steerage materials to guarantee that the person can accurately interpret the displayed data.
The abbreviation “KT” is appended to indicate the utilization of knots for wind speed. Modifier . “AUTO” identifies a METAR/SPECI report as an automated climate report with no human intervention. If “AUTO” is shown within the body of the report, the type of sensor gear used at the station might be encoded within the remarks part of the report. The absence of “AUTO” indicates that a report was made manually by an observer or that an automated report had human augmentation/backup.
U.S. army stations might not report a SPECI based on RVR. Wind path adjustments by 45° or extra, in lower than 15 minutes, and the wind velocity is 10 kt or more throughout the wind shift. Even if the roads simply look moist they may still be slick.
A temporary assertion describing the kind, location and motion of climate systems and/or air plenty which might have an effect on the proposed flight. Pilots flying into areas of minimal VFR climate could encounter unforecasted lowering circumstances that place the plane exterior the pilot’s scores and expertise stage. This may result in spatial disorientation and/or loss of control of the plane. Other Sources of Weather Information 1. Weather and aeronautical information can be found from numerous non-public industry sources on an individual or contract pay basis.
