Final answer:
The lost communication procedure for returning to LAAF per the LADD SOP involves climbing to a specific altitude, maintaining a heading, and executing the Lost Aircraft and Aircrew Procedure. The specific procedures vary between day and night.
Step-by-step explanation:
In accordance with the LADD SOP, the lost communication procedure for returning to LAAF (Lost Aircraft and Aircrew) varies depending on whether it is day or night.
During daytime, pilots are required to climb to an altitude of 5,000 feet above their current altitude and maintain their last assigned heading for 5 minutes. After this time, they should turn 90 degrees to the right and fly for 3 minutes.
Finally, they must execute the Lost Aircraft and Aircrew Procedure (LAAP), which involves performing a gradual descent until the aircraft is leveled off at an altitude of 2,500 feet.
During nighttime, the procedure is slightly different. Pilots should climb to an altitude of 10,000 feet above their current altitude and maintain their last assigned heading for 5 minutes. After this time, they should turn 90 degrees to the right and fly for 3 minutes.
Similar to the daytime procedure, they must then execute the LAAP by performing a gradual descent until the aircraft is leveled off at an altitude of 2,500 feet.
It is important to note that these procedures are specific to the LAAF and may not be applicable to other aviation organizations or agencies.
