Alternate Airports
- Alternate airports for Domestic and Flag flights must be listed in OpSpec C070
- Alternate airports for Supplemental flights must be suitable for the aircraft type
Marginal Weather
Per Silver Airways, marginal weather is defined as conditions forecasted for the destination AND first alternate airport are less than 800’ ceiling OR less than 2sm visibility at the estimated time of arrival.
Destination alternate domestic
A destination alternate is always required unless, 123 rule applies.
Flag destination alternate
Silver is granted OpSpec A012 which allows Domestic Operations to certain airports outside the contiguous United States. These airport are listed on A012. (Which means domestic destination alternate rule applies)
For airports not listed in A012 , a destination alternate is required unless;
- The flight is scheduled for not more than 6 hours (block to block) at least 1hr before and 1hr after the estimated time of arrival, the weather reports or forecasts, or a combination of both indicate;
- At least 1500’ above the lowest published instrument approach minimum or 2000’ above the airport elevation, whichever is greater
- The visibility at that airport will be at least 3sm or 2sm more than the lowest applicable visibility minimums, whichever is greater.
Supplemental destination alternate
A destination alternate is always required. However, if the flight is operated between two C070 airports, you don’t need an alternate if the 123 rule applies for domestic. The same applies for international supplemental flights, if airports are in the C070 airports, the flag destination alternate rule applies.
Takeoff Alternate
- Takeoff alternate is required if the weather conditions at the time of for departure airport are below authorized landing minimums for the appropriate runway.
- The airport must be no more than 1hr from the departure airport at normal cruising speed in still air with one engine inoperative and must meet the minimums prescribed in OpSpec C055 for alternate airports.
-Silver uses the distances in the table below as the equivalent of 1hr from the departure airport;
SF34 125NM
AT46 195NM
AT76 195NM

OsPecs C055
Alternate Airport IFR WX MIN
1 Navaid Rule - add 400’ to MDH or DH and 1SM (1600m) to the visibility to airports with at least 1 operational navigational facility
2 Navaid Rule - Add 200’ to MDH or DH and 1/2SM (800m) to the visibility to the higher of the two approaches used to airports with at least two operational navigations facilities to different suitable runways.
- Must not use any IAP to an airport which specifies that alternate wx minimums are not authorized.
- Determining a suitable runway, take into consideration wind (including gust, max cross wind, tail wind for the company)
- Check Notams to verify the navigation facilities are operational and not out of service or unmonitored
