Emergency autoland system
Autoland systems and processes for landing an aircraft without pilot intervention are described. In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft; calculate a merit for each potential destination identified; select a destination based upon the merit; and create a route from a current position of the aircraft to an approach fix associated with the destination that accounts for the terrain characteristic(s) and/or obstacle characteristic(s). The processor can also cause the aircraft to traverse the route, determine a final approach segment associated with the route; identify terrain characteristic(s) and/or obstacle characteristic(s) associated with the final approach segment; and determine an adjusted final approach segment accounting for the terrain characteristic(s) and/or obstacle characteristic(s).
1. An aircraft autoland system for an aircraft, the system comprising:
a memory operable to store one or more modules; and
a processor coupled to the memory, the processor operable to execute the one or more modules to cause the processor to:
identify a missed approach point associated with a published approach;
adjust the missed approach point to create a final approach segment;
create a route from a current position of the aircraft to the final approach segment; and
cause the aircraft to land utilizing the final approach segment without requiring pilot intervention,
wherein the processor is operable to adjust a final approach fix associated with the published approach to create the final approach segment.
2. The system of claim 1 , wherein the processor is operable to adjust the final approach fix and the missed approach point based on an original glide path angle associated with the published approach.
3. The system of claim 2 , wherein the processor is operable to adjust an altitude of at least one of the final approach fix and the missed approach point based on the original glide path angle so that the final approach segment has the same approach angle as the original glide path angle.
4. The system of claim 1 , wherein the missed approach point is adjusted based on a position of a runway associated with the published approach.
5. The system of claim 4 , wherein the missed approach point is adjusted to align with the runway.
6. The system of claim 1 , wherein the processor is operable to select a destination for autolanding based on published approaches corresponding to a plurality of destinations.
7. An aircraft autoland system for an aircraft, the system comprising:
a memory operable to store one or more modules; and
a processor coupled to the memory, the processor operable to execute the one or more modules to cause the processor to:
identify a missed approach point and a final approach fix associated with a published approach;
adjust the final approach fix and the missed approach point to create a final approach segment;
create a route from a current position of the aircraft to the adjusted final approach fix; and
cause the aircraft to land utilizing the created route and the final approach segment without requiring pilot intervention.
8. The system of claim 7 , wherein the processor is operable to adjust the final approach fix and the missed approach point based on an original glide path angle associated with the published approach.
9. The system of claim 8 , wherein the processor is operable to adjust an altitude of at least one of the final approach fix and the missed approach point based on the original glide path angle so that the final approach segment has the same approach angle as the original glide path angle.
10. The system of claim 7 , wherein the missed approach point is adjusted based on a position of a runway associated with the published approach.
11. The system of claim 10 , wherein the missed approach point is adjusted to align with the runway.

identifying a missed approach point and a final approach fix associated with a published approach;
adjusting the missed approach point and the final approach fix to create a final approach segment;
creating a route from a current position of the aircraft to the final approach segment;
causing the aircraft to land utilizing the final approach segment without requiring pilot intervention.
