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.
Can a GPS approach be used as an alternate?
The point of the special rules using GPS as an alternate has to do with the fact that non-WAAS GPS is supplementary navigation. So you can file with the destination or the alternate having only a GPS approach, but not both. WAAS-equipped aircraft can file for destinations and alternates having only GPS approaches.
When must you file an alternate airport?
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).
How do you find alternate minimums?
To view the non-standard IFR alternate minimums information, you will need to go to the Airports page > search for the airport > on the Procedures sub-tab, tap on Arrival > and then look for the Alternate minimums line. If there is an entry, tap on it and swipe through the pages until you find the airport in question.
Where can you find non standard alternate minimums?
What are the IFR rules for alternate airports?
1 Answer. FAR 91.169 states that IFR flight plans must include an alternate airport unless the weather is at least 2000 ft ceiling and 3 miles visibility, from one hour before to one hour afterwards ( 1-2-3 rule ).
What are the minimum requirements for an alternate flight?
You have to look at the approaches available at the alternate to know what the minimum requirements are there. If the alternate airport has a “precision” approach (for instance, an ILS), the FORECASTED weather at the ALTERNATE has to be at least 600 ft. ceiling and at least 2 mi visibility, otherwise you can’t list it as an alternate.
Can a tso-c145 fly to an alternate destination?
However, if your aircraft has a properly installed and operated GPS (see the TSO requirements in the AIM/AC references below) you can flight plan to your destination and alternate as follows: TSO -C145/-C146 ( WAAS Equipped Aircraft) – Both the destination and the alternate can be airports with only GPS approaches available.
What do you need to know about alternate airports?
Basically, to qualify as an alternate airport, the alternate must have certain forecast weather conditions (600-2 for precision approach, 800-2 for non-precision.) These are the “alternate minimums”.
