Instrument Procedures HandbookAn off-route obstruction clearance altitude (OROCA) is an off-route altitude that provides obstruction clearance with a 1,000-foot buffer in non- mountainous terrain areas and a 2,000-foot buffer in designated mountainous areas within the United States.
What is the minimum safe altitude for VFR EASA? except when necessary for take-off or landing, or except when specifically authorised by the CAA, a VFR flight at night shall be flown at a level that is at least 1000FT above the highest obstacle located within 8 KM of the estimated position of the aircraft.
The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.
The VFR Cruising Altitude rule does not apply below 3,000 feet AGL. There are some altitudes, however, that pilots seem to choose for level flight. Close to sea level they are 1000, 1500, 2000 and 2500. They are easy to read and remember on an altimeter.
You need to name an alternate airport on your IFR flight plan if, for the period of time one hour before and one hour after your estimated time of arrival, the weather is forecast to include a ceiling of 2,000 feet agl and/or visibilities less than three statute miles (the 1-2-3 rule).
What is the 3 1 rule IFR? In aviation, the rule of three or 3:1 rule of descent is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent.
In accordance with SERA. 5005 (c)(5), VFR flights in the United Kingdom at night may be flown below a level which is at least 300 M (1000 FT) above the highest obstacle located within 8 KM of the estimated position of the aircraft subject to the conditions at paragraph (e).
Why Do Pilots Prefer IFR Over VFR? IFR provides pilots with greater flexibility when it comes to controlled airspace, weather conditions, and career opportunities.
This brings us to IFR (instrument flight rule) pilots. IFR flying is astronomically more challenging than VFR flying, but those pilots who achieve this distinction are invariably more equipped to fly IFR and VFR. Aviating under IFR, a pilot is authorized to fly into clouds in what is called zero visibility.
