When are you required to file a Second Alternate due to Exemption 17347?

• A. Dispatched under Exemption 17347
• B. Marginal Weather at Destination
• C. Alternate is not available
• D. If destination is below minimums

Answer: (A)

Exemption 17347 changes how alternate planning is handled in dispatch. When a flight is dispatched under this exemption, a Second Alternate must be filed to provide an additional fallback airport beyond the destination and the first alternate. The other conditions described—marginal weather at the destination, no alternate available, or the destination being below minimums—affect whether you need an alternate in the first place, but they don’t by themselves trigger the exemption’s requirement for a second alternate. So the situation that calls for a Second Alternate due to Exemption 17347 is dispatch under that exemption itself.
