Question 12

Flag destination alternate

Answer 12

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.

Question 13

Supplemental destination alternate

Answer 13

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.

Question 20

OsPecs C055

Answer 20

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
