DESTINATION ALTERNATE REQUIREMENTS “1-2-3” RULE
A destination alternate is always required unless: an instrument approach is published and available for destination, AND,
* for at least 1 hour before to 1 hour after ETA,
* Ceiling will be at least 2,000’ above airport elevation, and
* Visibility will be at least 3 SM.

ALTITUDE TO FLY
The highest of “MEA”
* M - Minimum altitude prescribed for IFR
* E - Expected
* A - Assigned
LOST COMMUNICATION
ROUTE TO FLY
Select the route by this order: “AVE F”
1. A - Assigned route.
2. V - as Vectored.
3. E - last Expected.
4. F - Filed route.
LOST COMMUNICATION
LEAVING CLEARANCE LIMIT
Is the clearance limit a fix from which an approach begins?
* YES - start descent and approach as close as possible to the EFC, or ETA.
* NO - At EFC or clearance limit, proceed to a fix from which an approach begins and start the approach.
WHEN CAN YOU DESCEND BELOW DA / MDA?
- The aircrft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers.
- The flight visibility (or enhanced, if equipped) is not less than the visibility prescribed in the approach being used.
- At least one visual reference for the intended runway is distictly visible and identifiable to the pilot (except CAT II & III approaches).
VISUAL REFERENCES FOR DESCENDING BELOW DA / MDA
- The approach light system, except the pilot may not descend below 100’ above the touchdown zone elevation using the approach lights as reference unlesss the red termination bars or red side row bars are also distinctly visible and identifiable.
- Threshold, markings, or lights.
- Runway end identifier lights.
- Visual glide slope indicator.
- Touchdown zone, markings, or lights.
- Runway, markings, or lights.

EXCEPTION
If the aircraft minimum safe airspeed for any particular operation is greater than the max speed prescribed, the aircraft may be operated at that minimum speed.
