Module Ops.RescueHelo
Ops - Rescue helicopter for carrier operations.
Recue helicopter for carrier operations.
Main Features:
- Close formation with carrier.
- No restrictions regarding carrier waypoints and heading.
- Automatic respawning on empty fuel for 24/7 operations.
- Automatic rescuing of crashed or ejected pilots in the vicinity of the carrier.
- Multiple helos at different carriers due to object oriented approach.
- Finite State Machine (FSM) implementation.
Known (DCS) Issues
- CH-53E does only report 27.5% fuel even if fuel is set to 100% in the ME. See bug report
- CH-53E does not accept USS Tarawa as landing airbase (even it can be spawned on it).
- Helos dont move away from their landing position on carriers.

Rescue Helo
Recue Helo
The rescue helo will fly in close formation with another unit, which is typically an aircraft carrier.
It's mission is to rescue crashed or ejected pilots. Well, and to look cool...
Simple Script
In the mission editor you have to set up a carrier unit, which will act as "mother". In the following, this unit will be named "USS Stennis".
Secondly, you need to define a rescue helicopter group in the mission editor and set it to "LATE ACTIVATED". The name of the group we'll use is "Recue Helo".
The basic script is very simple and consists of only two lines.
RescueheloStennis=RESCUEHELO:New(UNIT:FindByName("USS Stennis"), "Rescue Helo")
RescueheloStennis:Start()
The first line will create a new #RESCUEHELO object via RESCUEHELO.New and the second line starts the process by calling RESCUEHELO.Start.
NOTE that it is very important to define the RESCUEHELO object as global variable. Otherwise, the lua garbage collector will kill the formation for unknown reasons!
By default, the helo will be spawned on the USS Stennis with hot engines. Then it will take off and go on station on the starboard side of the boat.
Once the helo is out of fuel, it will return to the carrier. When the helo lands, it will be respawned immidiately and go back on station.
If a unit crashes or a pilot ejects within a radius of 30 km from the USS Stennis, the helo will automatically fly to the crash side and rescue to pilot. This will take around 5 minutes. After that, the helo will return to the Stennis, land there and bring back the poor guy. When this is done, the helo will go back on station.
Fine Tuning
The implementation allows to customize quite a few settings easily via user API functions.
Takeoff Type
By default, the helo is spawned with running engines on the carrier. The mission designer has set option to set the take off type via the RESCUEHELO.SetTakeoff function. Or via shortcuts
- RESCUEHELO.SetTakeoffHot(): Will set the takeoff to hot, which is also the default.
- RESCUEHELO.SetTakeoffCold(): Will set the takeoff type to cold, i.e. with engines off.
- RESCUEHELO.SetTakeoffAir(): Will set the takeoff type to air, i.e. the helo will be spawned in air near the unit which he follows.
For example,
RescueheloStennis=RESCUEHELO:New(UNIT:FindByName("USS Stennis"), "Rescue Helo")
RescueheloStennis:SetTakeoffAir()
RescueheloStennis:Start()
will spawn the helo near the USS Stennis in air.
Spawning in air is not as realistic but can be useful do avoid DCS bugs and shortcomings like aircraft crashing into each other on the flight deck.
Note that when spawning in air is set, the helo will also not return to the boat, once it is out of fuel. Instead it will be respawned in air.
If only the first spawning should happen on the carrier, one use the RESCUEHELO.SetRespawnInAir() function to command that all subsequent spawning will happen in air.
If the helo should no be respawned at all, one can set RESCUEHELO.SetRespawnOff().
Home Base
It is possible to define a "home base" other than the aircraft carrier using the RESCUEHELO.SetHomeBase(airbase) function, where airbase is a Wrapper.Airbase#AIRBASE object or simply the name of the airbase.
For example, one could imagine a strike group, and the helo will be spawned from another ship which has a helo pad.
RescueheloStennis=RESCUEHELO:New(UNIT:FindByName("USS Stennis"), "Rescue Helo")
RescueheloStennis:SetHomeBase(AIRBASE:FindByName("USS Normandy"))
RescueheloStennis:Start()
In this case, the helo will be spawned on the USS Normandy and then make its way to the USS Stennis to establish the formation. Note that the distance to the mother ship should be rather small since the helo will go there very slowly.
Once the helo runs out of fuel, it will return to the USS Normandy and not the Stennis for respawning.
Formation Position
The position of the helo relative to the mother ship can be tuned via the functions
- RESCUEHELO.SetAltitude(altitude), where altitude is the altitude the helo flies at in meters. Default is 70 meters.
- RESCUEHELO.SetOffsetX(distance), where *distance is the distance in the direction of movement of the carrier. Default is 200 meters.
- RESCUEHELO.SetOffsetZ(distance), where *distance is the distance on the starboard side. Default is 100 meters.
Rescue Operations
By default the rescue helo will start a rescue operation if an aircraft crashes or a pilot ejects in the vicinity of the carrier. This is restricted to aircraft of the same coalition as the rescue helo. Enemy (or neutral) pilots will be left on their own.
The standard "rescue zone" has a radius of 15 NM (~28 km) around the carrier. The radius can be adjusted via the RESCUEHELO.SetRescueZone(radius) functions, where radius is the radius of the zone in nautical miles. If you use multiple rescue helos in the same mission, you might want to ensure that the radii are not overlapping so that two helos try to rescue the same pilot. But it should not hurt either way.
Once the helo reaches the crash site, the rescue operation will last 5 minutes. This time can be changed by RESCUEHELO.SetRescueDuration(speed), where the speed is given in knots.
If no rescue operations should be carried out by the helo, this option can be completely disabled by using RESCUEHELO.SetRescueOff().
Finite State Machine
The implementation uses a Finite State Machine (FSM). This allows the mission designer to hook in to certain events.
- RESCUEHELO.Start: This eventfunction starts the FMS process and initialized parameters and spawns the helo. DCS event handling is started.
- RESCUEHELO.Status: This eventfunction is called in regular intervals (~60 seconds) and checks the status of the helo and carrier. It triggers other events if necessary.
- RESCUEHELO.Rescue: This eventfunction commands the helo to go on a rescue operation at a certain coordinate.
- RESCUEHELO.RTB: This eventsfunction sends the helo to its home base (usually the carrier). This is called once the helo runs low on gas.
- RESCUEHELO.Run: This eventfunction is called when the helo resumes normal operations and goes back on station.
- RESCUEHELO.Stop: This eventfunction stops the FSM by unhandling DCS events.
The mission designer can capture these events by RESCUEHELO.OnAfterEventname functions, e.g. RESCUEHELO.OnAfterRescue.
Debugging
In case you have problems, it is always a good idea to have a look at your DCS log file. You find it in your "Saved Games" folder, so for example in
C:\Users\<yourname>\Saved Games\DCS\Logs\dcs.log
All output concerning the #RESCUEHELO class should have the string "RESCUEHELO" in the corresponding line. Searching for lines that contain the string "error" or "nil" can also give you a hint what's wrong.
The verbosity of the output can be increased by adding the following lines to your script:
BASE:TraceOnOff(true)
BASE:TraceLevel(1)
BASE:TraceClass("RESCUEHELO")
To get even more output you can increase the trace level to 2 or even 3, c.f. Core.Base#BASE for more details.
Debug Mode
You have the option to enable the debug mode for this class via the RESCUEHELO.SetDebugModeON function. If enabled, text messages about the helo status will be displayed on screen and marks of the pattern created on the F10 map.

Return value:
The SubFSM.
Adds a score for the FSM to be achieved.
Defined in:
Parameters:
#string State
is the state of the process when the score needs to be given. (See the relevant state descriptions of the process).
#string ScoreText
is a text describing the score that is given according the status.
#number Score
is a number providing the score of the status.
Return value:
#FSM:
self
Adds a score for the FSM_PROCESS to be achieved.
Defined in:
Parameters:
#string From
is the From State of the main process.
#string Event
is the Event of the main process.
#string State
is the state of the process when the score needs to be given. (See the relevant state descriptions of the process).
#string ScoreText
is a text describing the score that is given according the status.
#number Score
is a number providing the score of the status.
Return value:
#FSM:
self
Add a new transition rule to the FSM.
A transition rule defines when and if the FSM can transition from a state towards another state upon a triggered event.
