How do you determine an airports alternate minimums?
How do you determine an airports alternate minimums? The airport's alternate minimums, standard or nonstandard, are listed on the airport's 10-9 page. If you're able to use the ILS to runway 7 at KDAB, your alternate minimum weather can be as low as 700' ceilings and 2 SM visibility. That's not quite as low as standard precision alternate minimums, but it is close.
What is alternate rule?
14 CFR 91.169 (b) (2) (i) states that an alternate airport is not required if “for at least 1 hour before and for 1 hour after the estimated time of arrival the ceiling will be at least 2000 feet above the airport elevation and the visibility will be at least 3 statute miles.” To help remember those conditions of the ...
What are the standard alternate minimums?
Standard alternate minimums for non-precision approaches and approaches with vertical guidance [NDB, VOR, LOC, TACAN, LDA, SDF, VOR/DME, ASR, RNAV (GPS) or RNAV (RNP)] are 800-2. Standard alternate minimums for precision approaches (ILS, PAR, or GLS) are 600-2.
What is the takeoff minimum for IFR?
Standard takeoff minima are one statute mile for aircraft having two engines or less and one-half statute mile for aircraft having more than two engines. Specified ceiling and visibility minima will allow visual avoidance of obstacles during the initial climb at the standard climb gradient.
Can you use an airport without an approach as an alternate?
This does not mean you cannot file IFR to such an airport, but there are some restrictions. First, any time you file IFR to an airport without a published approach, you must file an alternate, no matter how good the weather is forecast to be at the planned destination.
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.
What is the VOR rule of 60?
The 1 in 60 rule states that if you're off course by 1NM after 60 miles flown, you have a 1-degree tracking error. Time to correct that heading! Another tip: If you're 60 miles away from a VOR, and you're off course by one degree, you're off course by one mile.
Does ATC know your alternate?
ATC receives only your filed destination, not the alternate. This is why ATC has to ask where a pilot wants to divert. To give ATC a heads up on where you want to go, you can write it in the remarks section, which is transmitted to ATC.
What is the 500ft rule in aviation?
An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.
