Alternates
Here we have to nominate the airports that are to be listed. Obviously,
if the value of the ‚Altn Required‘ field is either ‚None‘ or ‚Isolated‘,
there is no need to specify destination alternate airports at all. However,
for numeric values we need to nominate either 1 or 2 airports (refer to
page 80 -Alternate Airports).
For each destination alternate airport, PFPX will calculate a route from
the planned destination airport to that airport. It will also identify the
arrival procedure and up-wind runway that may be used, the distance
to the destination alternate airport, and calculate the fuel required.
