FOM Quick Reference Guide Flashcards
If weather is below landing MIN at the departure airport, T/O ALT must be added within:
400 NM
When is a second destination ALT required
If destination and first ALT are both marginal
What is the 1-2-3 ALT rule
An ALT is required if forecast weather at destination is:
+/- 1 hour of ETA is less than 2000’ ceilings or 3 sm visibility. Conditional terms such as TEMPO OR PROB will also require an ALT.
What is the 1-1-3 ALT rule
Within the lower 48 states or returning from extended domestic operation an ALT is required if forecast weather is: +/- 1 hour of ETA is less than 1000’ ceilings or 3 sm visibility. CAT 1 runway must be legal and available.
What is the 1-1-2 ALT rule
Within the lower 48 states or returning from extended domestic operation an ALT is required if forecast weather is: +/- 1 hour of ETA is less than 1000’ ceilings or 2 sm visibility. CAT II/III runway must be legal and available.
When is using the 1-1-3 or the 1-1-2 rule not an option
When TEMP OR PROB is in the forecast
If a listed ALT is going to be below minimums at the time a flight would arrive, can it be changed?
Yes with Dispatch concurrence to amend the release.
What if an ALT is no longer required?
Captain and Dispatcher may agree to amend the release and delete the ALT. ALT fuel will then become extra fuel.
In addition to regulatory requirements, ALT will be added for the following reasons:
Crosswind: An alternate will be designated whenever crosswind performance guidelines may prevent a safe landing.
Unlighted Airport: A flight scheduled to land at an unlighted airport 30 min before sunset and must have a lighted ALT.
Enroute Alternates (Engine Out Drift Down) requirements
Same as destination ALT requirements
Can a No Tower Airport be used as an ALT
Yes as long as the Approach Plate does not prohibit its use as an ALT. The navaid is monitored.
Determining Alternate Weather Minimums for an airport with just one operational approach facility
For airports with one operational approach facility:
- Add 400 to the authorized MDA or DA
- Add 1 mile to the minimum visibility
Determining Alternate Weather Minimums for an airport with two operational approach facilities to different runways
- Add 200 feet to the higher authorized MDA or DA for the two specified approaches, or add 400 feet to the lower authorized MDA or DA for the specified approaches.
- Add 1 mile to the lower visibility minimum specified for the two approaches or add 1/2 mile to the higher visibility minimum specified for the two approaches.
Use the lowest value obtained from each.
Determining Alternate Weather Minimums for airports with CAT II/III approach and at least two operational ILS facilities serving different runways
- With a CAT II procedure: 300 foot ceiling and RVR 4000/ 3/4 mile visibility
- With a CAT III procedure: 200 foot ceiling and RVR 1800/ 1/2 mile
