Eurocopter MH-65 Dolphin

MH-65 is a capable helicopter for search and rescue (SAR) and medevac. This version is single engine, medium-low size that fits perfectly on the deck of a hospital ship. The Advanced Fly By Wire system is more advanced and flexible than the stormworks gyro, and offers a relaxed flying with multiple modes that suits the situation.

I will continue to improve/update and paint to original US coast guard livery. If you have any improvements please feel free to comment down below

• Advanced Fly By Wire System including Altitude hold, precision Autohover and trim hold
  
• Navigation suite with map, integrated FMS, Navigation display and Locator Finder
  
• Winch for 2, operated by Cockpit, Cabin or Hardness
  
• Single or Multiplayer compatible
  
• Realistic Cockpit
  
• Radio
  
• Radar
  
• Search light tracking the pilots head
  
• Equipment for Search and Rescue
  
• Camera planned
  
• Top speed around 50m/s. Not recommended above
  
• Endurance ca100 minutes
  
• Range ca 300km
  
• Control using WASD or Arrow keys (WASD collective and yaw, arrow keys roll and pitch as default)

This helicopter was made for singleplayer, but is very much fin with friends as well. The autohover and altitude hold works perfect when hovering above the water, winching down to rescue stranded people. I recommend to lift and store the winch hardness inside the cabin.

1. Fuel and electrical hose disconnected
   
2. Make sure the doors are closed and winch is stowed inside cabin
   
3. Gear extended (flip switch off)
   
4. Check switch if you want to use WASD keys for controlling instead of arrow keys
   
5. Check fuel
   
6. Nav lights on
   
7. Park brake on by indicator
   
8. Hook/Magnet connected by indicator
   
9. Battery above 0.5
   
10. Emergency locator transmitter not active by indicator (switch on and off to deactivate)

1. Battery on
   
2. Anti collision lights on (flash used for starting, steady for flight)
   
3. Engine Run
   
4. Start
   
5. Confirm Starting by indicator, rotor and battery charge negative
   
6. Engine Start out, RPS should be above 14, around 16 for normal flight
   
7. Fuel flow 40-60
   
8. Avionics on
   
9. Cockpit light as desired
   
10. Dim instruments as desired
    
11. Heater as desired (will keep temperature around 22 deg C)
    
12. Set up navigation and radio
    
13. Search light on before take off (landing light)
    
14. Release Hook/Magnet and ropes with Pilot Hotkey 4

I use Altitude hold when take off. Toggle by Pilot Hotkey 2 and increase altitude using W key. Engine RPS might decrease and indicator lit when first take off as the engine encounters load and spooling up. You should be airborne within a few seconds.


A microcontroller with Proportional–Integral–Derivative controllers (PID) is used for controlling the helicopter instead of the default stormworks Gyro. This system was a real pain to make, but the reason for making this helicopter as well. By manually adjusting PIDs it will tune (almost) perfectly with the helicopter and have the ability for multiple control methods.
Note* This system is known to sometimes oscillate with very high rotor load or unusual flight maneuvers.
The helicopter respond by the pilot stick and command a Roll-moment within the flight envelope.



Altitude Hold is toggled by Pilot Hotkey 2. When active you can see the set altitude in purple (4) by the altitude(5). Altitude can be increased/decreased by WS keys. I use altitude hold from ground to ground (almost always).
Rate of climb (purple) and collective power(green) (7). Speed in m/s (1)
Ground in yellow bar by radar altimeter around 30m altitude above ground/sea (6).

Autohover is toggled by Pilot Hotkey 1. When active a "H" (2) symbol appear on the PFD with a cross (3) (replacing the "T"). The helicopter will hold GPS position and direction. Recommended together with altitude hold. Use arrow keys to adjust position forward/aft/left/right and AD keys for heading. (10) shows heading command error in blue text. Note* The helicopter will jiggle a bit when maneuvering with arrow keys due when releasing the keys the helicopter transition from moving to instantly holding position causing rapid movement. This is intended.

Trim hold is toggled by Pilot Trigger. When active a "T" (2) appear and a cross (3). You can move around with arrow keys and the helicopter will hold the current attitude and heading. This is for normal flying, hovering, landing or you just want to relax on the controls. Not recommended for speeds above 50 m/s as the helicopter will struggle to maintain attitude and altitude. The helicopter will not be very willing to yaw/turn at speed above 40.



The map is integrated with the Horizontal Situation Indicator (HSI) bellow the attitude.




It will automatically switch to next waypoint. You can move around and zoom the map using U/D/L/R +/- or reset with ~ (17). To create a waypoint, make sure the "NAV" (19) is indicated and press the screen where you want the waypoint. Select waypoint to edit/create with the arrows (11).
HSI Current waypoint (12) and direction (8), time and distance (9).
With "POI" (19) you can click on the map to get X and Y coordinates (15) without creating waypoints.
Current active waypoint for navigation on the HSI (12).
Next and previous waypoint (13) or reset (14)
NEW: The map display have Day/Night mode which is adjusted with the avionics brightness buttons overhead. You can select waypoint to manipulate/create top left.
If you want to manually type in the waypoint, make sure you have the desired waypoint number (11), use the FMS touch display (Radio left side, FMS Right side center pedestal). Your number will also display on the map in green text. Type the number, if negative press "-", press "X" or "Y" and hit enter. Use "B" for backspace or "R" to reset. To change active WP type the number you want and "A". To change the waypoint to edit/create type the number and press "E".



Before landing make sure that the landing gear is extended, park brake is on (indicator) and flip the "Hook/Magnet" switch. When landing (recommended in Altitude hold and Autohover/Trim hold) a magnet under the helicopter will grab the deck and the "Connected" indicator will activate. Throttle down (deactivate altitude hold) and secure the helicopter with ropes.
When taking off, start the helicopter with the magnet and ropes (only rope anchor!) and when ready to fly press Pilot Hotkey 4 to release ropes and magnet.



Livery might change to US default livery.
Note* I do not want reuploads or copy of this creation, and I make all microcontrollers myself, and do ask you to not copy and upload them.
