What is the minimum alternate for IFR?
What is the minimum alternate for IFR? It's called the 3-2-1 rule, and it's the easiest way to remember the regulation. To recap, if the weather at your destination isn't at least 3 SM of visibility and 2000' AGL ceilings from 1 hour before to 1 hour after your ETA, you need to file an alternate.
What is VFR vs IFR rules?
VFR is short for 'visual flight rules', meaning the pilot primarily controls and navigates the aircraft using outside visual references. IFR stands for 'instrument flight rules'. The aircraft is flown using only the instruments with no visual references to the outside world.
What is the 0123 rule for IFR?
1 hour before to 1 hour after your ETA (at the listed destination), the ceiling will be at least 2,000' AGL, and the visibility will be at least 3 SM. It's called the 1-2-3 rule; this is the easiest way to remember this section.
What is the minimum RVR for takeoff?
The lowest routinely used takeoff visibility minimum is 600 feet RVR, which is about one-tenth of a mile. Pretty low. It's the lowest visibility typically used in simulator training for taxi and takeoff practice.
What standard minimums are required to list an airport as an alternate on an IFR flight plan if the airport has VOR approach only?
What minimum weather conditions must be forecast for your ETA at an alternate airport that has only a VOR approach with standard alternate minimums, for the airport to be listed as a alternate on the IFR flight plan? 800-foot ceiling and 2 statute miles visibility.
What is the 3 1 rule for descent?
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. For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles.
Can you fly IFR without ATC?
In theory, a pilot can operate in sub-VMC conditions under IFR without an ATC clearance in Class G airspace. However, to enter or operate in controlled airspace under IFR, an ATC clearance is required.
