--- **AI** - Models the process of A2G patrolling and engaging ground targets for airplanes and helicopters.

-- @module AI.AI_Air_Patrol
-- @image AI_Air_To_Ground_Patrol.JPG
--- @type AI_AIR_PATROL
-- @extends AI.AI_Air#AI_AIR
--- The AI_AIR_PATROL class implements the core functions to patrol a @{Zone} by an AI @{Wrapper.Group} or @{Wrapper.Group}
-- and automatically engage any airborne enemies that are within a certain range or within a certain zone.
--
-- ![Process](..\Presentations\AI_CAP\Dia3.JPG)
--
-- The AI_AIR_PATROL is assigned a @{Wrapper.Group} and this must be done before the AI_AIR_PATROL process can be started using the **Start** event.
--
-- ![Process](..\Presentations\AI_CAP\Dia4.JPG)
--
-- The AI will fly towards the random 3D point within the patrol zone, using a random speed within the given altitude and speed limits.
-- Upon arrival at the 3D point, a new random 3D point will be selected within the patrol zone using the given limits.
--
-- ![Process](..\Presentations\AI_CAP\Dia5.JPG)
--
-- This cycle will continue.
--
-- ![Process](..\Presentations\AI_CAP\Dia6.JPG)
--
-- During the patrol, the AI will detect enemy targets, which are reported through the **Detected** event.
--
-- ![Process](..\Presentations\AI_CAP\Dia9.JPG)
--
-- When enemies are detected, the AI will automatically engage the enemy.
--
-- ![Process](..\Presentations\AI_CAP\Dia10.JPG)
--
-- Until a fuel or damage threshold has been reached by the AI, or when the AI is commanded to RTB.
-- When the fuel threshold has been reached, the airplane will fly towards the nearest friendly airbase and will land.
--
-- ![Process](..\Presentations\AI_CAP\Dia13.JPG)
--
-- ## 1. AI_AIR_PATROL constructor
--
-- * @{#AI_AIR_PATROL.New}(): Creates a new AI_AIR_PATROL object.
--
-- ## 2. AI_AIR_PATROL is a FSM
--
-- ![Process](..\Presentations\AI_CAP\Dia2.JPG)
--
-- ### 2.1 AI_AIR_PATROL States
--
-- * **None** ( Group ): The process is not started yet.
-- * **Patrolling** ( Group ): The AI is patrolling the Patrol Zone.
-- * **Engaging** ( Group ): The AI is engaging the bogeys.
-- * **Returning** ( Group ): The AI is returning to Base..
--
-- ### 2.2 AI_AIR_PATROL Events
--
-- * **@{AI.AI_Patrol#AI_PATROL_ZONE.Start}**: Start the process.
-- * **@{AI.AI_Patrol#AI_PATROL_ZONE.PatrolRoute}**: Route the AI to a new random 3D point within the Patrol Zone.
-- * **@{#AI_AIR_PATROL.Engage}**: Let the AI engage the bogeys.
-- * **@{#AI_AIR_PATROL.Abort}**: Aborts the engagement and return patrolling in the patrol zone.
-- * **@{AI.AI_Patrol#AI_PATROL_ZONE.RTB}**: Route the AI to the home base.
-- * **@{AI.AI_Patrol#AI_PATROL_ZONE.Detect}**: The AI is detecting targets.
-- * **@{AI.AI_Patrol#AI_PATROL_ZONE.Detected}**: The AI has detected new targets.
-- * **@{#AI_AIR_PATROL.Destroy}**: The AI has destroyed a bogey @{Wrapper.Unit}.
-- * **@{#AI_AIR_PATROL.Destroyed}**: The AI has destroyed all bogeys @{Wrapper.Unit}s assigned in the CAS task.
-- * **Status** ( Group ): The AI is checking status (fuel and damage). When the thresholds have been reached, the AI will RTB.
--
-- ## 3. Set the Range of Engagement
--
-- ![Range](..\Presentations\AI_CAP\Dia11.JPG)
--
-- An optional range can be set in meters,
-- that will define when the AI will engage with the detected airborne enemy targets.
-- The range can be beyond or smaller than the range of the Patrol Zone.
-- The range is applied at the position of the AI.
-- Use the method @{AI.AI_CAP#AI_AIR_PATROL.SetEngageRange}() to define that range.
--
-- ## 4. Set the Zone of Engagement
--
-- ![Zone](..\Presentations\AI_CAP\Dia12.JPG)
--
-- An optional @{Zone} can be set,
-- that will define when the AI will engage with the detected airborne enemy targets.
-- Use the method @{AI.AI_CAP#AI_AIR_PATROL.SetEngageZone}() to define that Zone.
