VFR / VMC visibility requirements in the US In aviation , visual meteorological conditions ( VMC ) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.
VFR requires a pilot to be able to see outside the cockpit to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft. [3] Governing agencies establish specific requirements for VFR flight, including minimum visibility, and distance from clouds, to ensure that aircraft operating under VFR are visible from enough distance to ensure safety.
The app supports flight planning features including letting pilots select routes based on IFR waypoints or using waypoints, checkpoints, or geographic features for VFR flight. [6] Pilots can factor instrument departure, arrival, and approach procedures into their route as well as traffic pattern entries to airports.
Avare is a free open source "moving map" aviation GPS, A/FD and EFB app for phones or tablets using the Android Operating System.The app uses any internal Android or compatible external GPS receiver to determine location, allowing real-time display of location, heading, speed, distance, time, and altitude on free U.S. FAA IFR or VFR aviation charts; or on select topographic charts.
In the US, Canada and Europe for eastbound (heading 0–179 degrees) IFR flights, the flight plan must list an "odd" flight level in 2000 foot increments starting at FL190 (i.e., FL190, FL210, FL230, etc.); Westbound (heading 180–359 degrees) IFR flights must list an "even" flight level in 2000 foot increments starting at FL180 (i.e., FL180 ...
In United States aviation, a sectional aeronautical chart, often called a sectional chart or a sectional for short, is a type of aeronautical chart designed for air navigation under visual flight rules (VFR). In Australia, Canada and some other countries, the equivalent charts used for visual flight are called VFR Navigation Charts (VNCs).
There are three sets of flight rules under which an aircraft can be flown: Visual Flight Rules (VFR) Special Visual Flight Rules (SVFR) Instrument Flight Rules (IFR) Public transport flights are almost exclusively operated under IFR, as this set of rules allows flight in regions of low visibility (e.g. cloud).
Flight planning is the process of producing a flight plan to describe a proposed aircraft flight. It involves two safety-critical aspects: fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air traffic control requirements, to minimise the risk of midair collision.
