    V1.0.0 - INITIAL RELEASE March 8, 2024

    Miltech Simulations CH47D is a tandem-rotor, heavy-lift helicopter designed for diverse missions including troop and cargo transport, medical evacuation, and construction support. Its powerful twin engines and counter-rotating rotors provide exceptional lifting capacity for internal or underslung loads. Its robust design and advanced systems allow for operation in demanding environments and ensure the successful completion of critical missions.

    Beautifully Modeled Helicopter: high-quality modeling and texturing throughout - exteriors and interiors.

    • Highly detailed Cockpit Model, with detailed wear and tear throughout.
    • Fully modeled cargo bay.
    • 4K Textures throughout, with sharp details and realistic damage/dirt maps.

    Realistic Animations: including working doors and cargo ramp, accurately rotating Tandem Rotors, Blade Droop, etc.

    Liveries: 13 Liveries, including US Army, RAF, Luftwaffe, Italian Esercito, Spain Ejercito, RCAF, Australian Army, etc. A layered paintkit is available upon request.

    Effects: Downwash effect (water, dirt); engine heat blur, volumetric lighting.

    Flight Model: Tailored flight and engine model, validated through testing and feedback from CH47 pilots and technicians.

    • Specialized flight model that accurately simulates the stability, maneuverability, and capacities of a Tandem Rotor Configuration.
    • The flight model makes use of the native helicopter Flight Model, enhanced with customized parameters to accurately simulate the expected behavior.
    • NOTE: FM Will be migrated to fully native Tandem Support after the release of SU15.

    Sounds: Comprehensive sound pack, developed from sounds recorded on real aircraft.

    • Comprehensive engine and rotor soundset, with distinct sounds for the iconic Blade Slap based on collective, pitch/roll angle, and High G slap.
    • Accurate depiction of APU sounds, FWD Transmission Whine and Ramp hydraulic sounds.

    Cargo Loading Capabilities:

    • 6 External Cargo Loads (Sling loads in both Tandem and Single-sling configurations), including Humvees, UAV Containers, Rhibs and even Helicopter Fuselages. External loads spawn in the world and are picked up by the aircraft by hovering above them.
    • 5 Internal Cargo Loads to choose from, including Medvacs, Troops, Humvee and Pallets.
    • Electronic Flight Bag: A Tablet EFB is included to interact with the aircraft systems - From Fueling to External Loads.

    Navigation Systems: Realistic instrumentation based on documentation from the CH7D.

    • Functional TACAN, ADF and VOR Navigation Systems.
    • Optional Aera-Style GPS, with more GPS options coming up soon (PMS GTN750, TDS GTNXi)

    Mission System: Set of predefined flights with tasks to execute.

    • Missions are designed so the pilot follows a set of Mission Dispatch Instructions but must fully configure, execute, and perform the mission by themselves.
    • These include fully functional Firefighting missions, Cargo Hoist missions, Rescue and Humanitarian missions, and Military Exercise missions.
    • Some missions may require Miltech Simulations Supercarrier Pro or Miltech Simulations UK Carrier Strike Group, sold separately.

    Complementary *Included* Sceneries and Scenes: The CH47D includes a set of sceneries and scenes to enhance the piloting experience.

    • RAF Odiham EGVO (UK), home of the No. 7, 18 and 27 squadrons.

                I'm sorry but I can't understand what "paintkit is available upon request" meaning.
                Do I need to email or something to get the paint kit?
                Or meaning that it will be available in the future?

                1. Send us an email and we'll send it to you.

                    Can I get a confirmation on a couple of things:

                    Blade length: Is it just me or do the blades seem to be bit too long? I may be out of pocket. My reference aircraft is a CH46e, that's what I am use to. I know that's a smaller helo. Would love some insight from a 47 driver.
                    Engine Torque gauge: Is that broken right now? I can hover with 20% torque, that's crazy.
                    Will there be an option to turn off or lower the engagement altitude of the rotorwash effects, right now it's engaging at 100-150 feet

                    Love the initial release and looking forward to the updates!
                    Semper FI

                    1. Noel,

                      Re: Torque, this is a current shortcoming of the current flight model. Will be fixed with the release of SU15 and support for native tandem rotors. We basically had to create a frictionless system for everything to work well, which means that the engines are barely doing any work (and therefore, barely any torque) unless you increase the collective quite a bit.

                      As for the Rotor wash effects, an update is coming tomorrow in this regard.

                      As for the blades, these are 30ft long. Accurately modeled :)

                          CH47 technician for the past 12 years and I've notice a few small details. Outstanding to finally see the Chinook in the simulator and applaud the amount of work and time put into this add on.

                          · EAPS is not installed and therefore not required to be turned on, if they were installed - there would be no reason to have the by-pass doors open with the fans turned on. The by-pass doors are used when the fan fails and the engine still requires air.
                          · It would be nice if the ramp had a 'level" position - level to the floor (I may missed this)

                          1. Jason,

                            Thanks for your feedback, will add those to our internal list to review

                                              Hi, thank you for the wonderful C47D! I bought V1.01 today and tested it straight away.
                                              But the downwash effect is gone! It is activated in the EFB! Thanks and Greetings.

                                              1. Effects are definitely there - but perhaps lighter than you may expect. We are working on improving them but its a delicate balance between performance and looks.

                                                    There is no difference between on and off.

                                                    1. There should be - At least I see it on my end. You should see a faint cloud of dust when hovering at around 30-50ft above ground. More noticeable when hovering above water.

                                                      As I said, this is being improved with careful consideration of performance impact.

                                                  • In reply toKamow52:

                                                      Must say I've never seen any downwash effect with either 1.0.1 or 1.0.2 - not even faint clouds. And I've definitely checked it's not disabled in the tablet. Feels like there might be either a graphics setting or conflict with some other mod that's preventing it from showing up.

                                                      I should be seeing some kind of downwash in this scenario, right? I've tried over a few different surface in case that's it, but still nothing.

                                                      1. No idea - the downwash are custom effects so it shouldn’t be any problem. I’ll do some digging.

                                                        Can you confirm its not visible from the outside cam, at around 40-50ft above ground?

                                                            I'll test it. Can you give me an airfield / location where it's definitely known to work please.

                                                            1. Anywhere should work. More visible over water and sand.

                                                                  OK all good - sorry for the false alarm! There's quite a narrow band of altitude where it works. I'd (mistakenly?) expected to see some downwash just as the wheels leave the ground, but it seems I need to be higher to see it. My previous tests must have passed through that band too quick to see anything.

                                                                  1. Has more to do with collective amounts rather than altitude. Increased collective will lift more dirt. Particularly noticeable in hovers. Perhaps could be tweaked a little more

                                                            Having trouble finding it in market place on Xbox, any suggestions?

                                                            1. Not released for Xbox yet. Will take 2-3 weeks more.

                                                                  2. Should l get the V1.0.1 12th March now or can l wait till V1.0.2 18th March and get both?
                                                                  3. Have tried posting the following question on the forum,

                                                                      Sorry should have attached this before sending above email.

                                                                      Love this aircraft!
                                                                      I have waited along time for it.
                                                                      I tried flying on line using JoinFS, the aircraft displays ok except
                                                                      for its front wheels dug into the ground,
                                                                      But when flying the other his aircraft does not leave the ground, just flies
                                                                      along it. nor does it display any height data. My aircraft looks the same to the guy l am flying with on his set,
                                                                      Both our aircraft display and fly fine on our own sets.
                                                                      Hope this makes sense.

                                                                        All updates are distributed on the app where you got the product (Contrail or ORBX Central). Just launch the app, and you will see the updates available under the downloads section. Easy.

                                                                        You can get updates anytime you want. Updates will be fully reinstalled, so all files are replaced. You can go from 1.0.0 to 1.0.2 without installing 1.01, same story with any future version.

                                                                        Unfortunately I'm unable to help you with FlyFS as I'm not familiar with the software or how it handles our model. Our product relies a lot on code that is not externally available over multiplayer, so it is expected that things may not function correctly, especially with 3rd party MP software.

                                                                      2. M

                                                                          I am a retired CH-47ABCD IP with 4,000+ hours
                                                                          Your team has developed an outstanding CH-47. Your programmers and design artist did an amazing job.
                                                                          I have a few ideas for your considerations

                                                                          1. Torque readings are not accurate when starting engines ( too high) , when moving the ECL to flight, and the torque should increase when trust lever is applied during normal and sling load operations. ( not to exceed 810 Lbs torque for 10 seconds).
                                                                          2. Cruise guide indicator should indicate relate forward airspeed in relation to speed trims not trust lever increase.
                                                                          3. Forward rotor blades tip path plane is too low.
                                                                          4. When ECL's are in ground position when starting rpm should be much lower, and increase when moved to flight position.
                                                                            5.When shutting down rotor system rpm does not decrease for a long time.
                                                                            These are by no means criticisms of your simulation, just suggestions to make it more real
                                                                            Thank you for your consideration.
                                                                          1. Hello,

                                                                            Thanks for your words and feedback. Most of the items you mention are being worked on, and will be fixed in future updates.

                                                                                Keep up the great work

                                                                                    the latest update is consistently getting better.

                                                                                    1. Crew chief outside helicopter during startup and shut down
                                                                                    2. Include blade tie-downs and engine covers to be removed before flight
                                                                                    3. It would enhance the realism if a crew chief could verbally respond to the pilots regarding startup, sling load operations, shut down, etc.
                                                                                      ready on APU start, fireguard posted on engine starts
                                                                                      Sling load operations: directions when hovering over loads, i.e. down 2, over left 4, etc, load is hooked, men are clear, up 5, sling is tight, up 10, load is off the ground, load secure for flight
                                                                                      Again these are only suggestions
                                                                                      your aircraft is outstanding
                                                                                      Thank you for your consideration.
