ATIS provides information on weather conditions, runway conditions, and other pertinent information for pilots. By tuning into the ATIS frequency for your departure and arrival airports, you can stay informed of the latest weather updates and any changes that may impact your flight.
Automated Weather Observing Systems (AWOS) and Automated Surface Observing Systems (ASOS) are automated weather stations located at airports and other aviation facilities. These systems provide continuous, real-time weather information, including temperature, dew point, wind speed and direction, visibility, and cloud cover. By accessing the AWOS or ASOS frequency for your departure and arrival airports, you can stay up-to-date on the latest weather conditions and make informed decisions regarding your flight.
Visual Flight Rules (VFR) require pilots to maintain visual reference to the ground and avoid flying in adverse weather conditions. To fly under VFR, specific weather minimums must be met, including minimum visibility and cloud clearance requirements. Understanding aviation weather is crucial for VFR pilots, as it helps them determine whether theycan safely fly under visual conditions and avoid potential hazards.
Instrument Flight Rules (IFR) require pilots to navigate and operate the aircraft solely by reference to instruments. IFR flight rules allow pilots to fly in conditions with reduced visibility and low cloud ceilings that would not be permitted under VFR. To fly under IFR, specific weather minimums must be met, including minimum visibility and cloud ceiling requirements. Understanding aviation weather is critical for IFR pilots as it helps them make informed decisions regarding their flight plan and route to ensure a safe and efficient flight.
Runway Visual Range (RVR) is a critical component of aviation weather and is defined as the horizontal distance a pilot can see down the runway from the approach end. RVR is measured using specific equipment located at the airport and is reported in feet or meters. Knowing the RVR is essential for pilots as it helps them determine whether they can land safely and meet the requirements for specific types of approaches.
CAT I and CAT II approaches are instrument approaches that allow pilots to land in low visibility conditions. CAT I approaches require a minimum RVR of 1,800 feet, while CAT II approaches require a minimum RVR of 1,200 feet. RVR plays a critical role in these types of approaches, as it determines whether the pilot can safely land the aircraft.
