The A-37 Dragonfly is a twin-engine, two-seat, side-by-side, ground attack and counter insurrection military jet designed by Cessna. It was developed in the 1960s, and was put into service in 1967. The A-37B succeeded the A-37A, which was a heavily converted T37.

The A-37B features 4 pair of pylons under the wings, and large wingtip tanks. Its landing gear is retractable, and the front wheel is steered by hydraulics connected to the rudder. It is powered by two General Electric J85-GE-17A tubojet engines, 2,850 lbf static thrust each.
Empty weight is about 6,200 lbs and maximum takeoff weight about 14,000 lbs.
Usable fuel quantities are 457.5 US gallons internal and up to 389.2 US gallons in droppable pylon tanks.
 
The VNE is 415 kts or Mach 0.7 and the cruising speed over 400 KTAS for clean aircraft. This MSFS aircraft is configured to have payloads under wings, so it's slower.
The Cessna A-37B was first used by USAF and South Vietnam Air Force during Vietnam war. Many machines were seized by North Vietnam, and flown by Vietnam People's Air Force.
The Dragonfly was a low cost aircraft, easy to maintain, and was bought by various countries. Some of them are still in service in 2023.
The USAF gradually replaced them with the A-10.

• Install :
      Simply unzip file into your community folder, but requires 2.8 GB free disk space
  
  
• Manual :
      Available in vrilleaplat-cessna-a-37\Manual_PDF subolder
      READ BEFORE USING THE AIRCRAFT. Don't think you can just press CTRL+E and do anything you want without crashing, or burning the engines.
      Don't complain about the aircraft not starting or burning if you don't follow the indicated prodecure.
      A printable simplified start checklist is also available.
  
• Features :
      Two 3D models variant, with refuel probe or not.
      Realistic fuel system, with jettisonable auxiliary tanks and dumpable wingtip tanks. Fuel dump effect.
      Removable weapons under pylons (aesthetic and weight only)
      Aerobatic smoke system : white and colored smoke are available. Full color spectrum.
      Six barreled minigun fire effects.
      Failures if you don't respect your plane. No failure because of time use. Smoke and fire effects.
      Tablet, well ... a special one.
      Three cold and dark start modes : default, persistent, and random
  
  
• Liveries :
      Many liveries have missing details, because of few low definition photos showing them. Some of theses liveries were made with only one picture available and are partially imaginated.
      When not beeing able to see exactly what is written, I used Google translate for spanish an korean inscriptions. These translations are unexact in most cases.
      Liveries are USA (2), Colombia (1), Chile (1), El Salvador (1), Honduras (1), Peru (1), Uruguay (1), Dominican Republic (1), Ecuator (1), South Korea (7, Black Eagles aerobatic team), Guatemala (1), Thailand (1), South Vietnam (2, Vietnam war era)
     
• CTRL+E procedure :
      This procedure doesn't work when hot start is activated.
      It should cut the throttles off and wait until RPM is high enough to set throttles to idle. I don't know how to achieve that.
      Follow the start procedure as it is described in the manual, it's not that difficult.

      All those who share their long acquired experience on making aircrafts, in forums like FSDeveloper.com or Pilote-Virtuel.com (in french), there are many names but they will recognize themselves as they know what they bring to the community
      Mac, who tested beta version and gave me some very useful feedback
      SomeGuyInCO who gave me solution to the inverted elevator trim on axis bug.
  
      Everyone who will now give me some constructive feedback
      Everyone who will now draw some new liveries : a paintkit is available as a separate download. The paintkit is likely to be less frequently updated, and I won't have to think about it, each time I'm preparing a package for a new A37 version.

There will probably be some issues with inverted elevator trim linked to an axis.

The paintkit is available here : https://fr.flightsim.to/file/63048/cessna-a-37-b-dragonfly-paintkit

Version 1.1 :

• Rank 3 tanks are available, limited to 72 USGal because of rank 3 pylon limited to 600lb load.
• Hot start is active by default but can be now disabled. It can be useful if your throttle command cancels cut-off without any action from you.
• Gun visor displayed like a HUD. Unfortunately, it seems MSFS doesn't allow any color but green, whereas it should be yellow.
• Persistent and random start modes extended to transponder code, radio and nav frequencies settings. Not extended to fuel levels because of bugs.
• Elevator sensitivity reduced (low angles)
• Static thrust corrected (was too low)
• Elevator trim is no more inverted when commanded by an axis, thanks to SomeGuyInCO.
• Various bug corrections.

Compatibility issue with SU14 should be over.

Version 1.1.1 :

• Game crash when loading under SU 14 should be fixed.
  It was caused by this loading tip : "577 A-37 B Dragonfly were built. 254 were delivered to South Vietnam, of which 95 were seized by North Vietnam, and used until a lack of parts rendered the last of these planes unusable in the early 1990s."
  This is ... too long for SU 14 ! (can't believe it)
• When starting cold & dark, ADF was out of order. Fixed.

If crashes still occur on your system : go to ...\vrilleaplat-cessna-a-37\SimObjects\Airplanes\vrilleaplat-cessna-a37
try to :
open aircraft.cfg file in notepad, and simply erase all tips0 to tips5 lines [Loading] section.
The section should look like this :

[LOADING]
ImageName = LOADING_FREEFLIGHT

Save aircraft.cfg file and close notepad.

Version 1.1.2 :

• When investigating about SU 14 crashing, I thought visual effects could be involved, so I deactivated them, and I forgot to bring them back later.

Version 1.1.3 :

• Overall drag reduced for spoilers, flaps and landing gear.

• Upgraded radio navigation devices available as an option. See manual, p. 16 for details.

Version 1.1.4 :

• Oops ! Glide slope was inverted (upgraded nav instruments option) Now fixed.

Version 1.1.5 :

• Ground power unit
• Edited generator curve
• Edited engine temp
• Edited manual, with table of contents
• One new livery : FACh J-629 desert camo
• Minor bugs fixes

Version 1.2 :

For FS 24 compatibility :

• collision with avatar when walking around. (enter the aircraft using shift+C, no clickspot)
• modified beacon lights so there is no light flooding in the cockpit
• tablet day lightness
• option for windshield scratches removal

However, there is no visible pilot in FS 24.
