  1. Captains, Today we're excited to announce a new developer to the commercial market! HotStart is the name, and the first product will be a very detailed Socata TBM 900. This particular product will also be jointly created with Goran Matovina of Leading Edge Simulations for the 3D modeling portion. The goal for release time as it stands is early summer of this year, so the wait won't be too long and we'll continually post updates here to ensure you can keep up to date. The HotStart TBM 900 will be a high-fidelity simulation of the TBM 900 high-performance single-engine turboprop aircraft. The model features a persistence system and wear & tear on all aircraft components to simulate the experience of owning and caring for the aircraft. All simulation state is fully persisted across reloads, so performing proper shutdown and cleanup after a flight is imperative. Shortlist of features: Heavily multi-threaded systems architecture to leverage performance of modern CPUs with many cores. Flight model tuned to perform to within a few percent of the real aircraft in the normal flight envelope, including maximum and stall speeds, rate of climb, fuel burn, trim behavior and control feel. Full aircraft state persistence. Every switch, flight control position, fuel state and on-airport position is restored upon reload. Even between reloads, system resources change in real time. The engine and oil cools down slowly between flights, the battery drains, tires slowly deflate, etc. Fine-grained systems model, down to individual sub-components. The always-on failure system realistically responds to wear & tear and overstress for each sub-component based on individual load factors. Over-torque, over-temp, frequent starts, hard landings, operating in FOD-contaminated environments and many more all affect individual sub-component wear & tear and service life. Sub-component wear realistically reflects on aircraft performance. Worn engine parts reduce maximum available power, worn prop reduces top speed, worn tires result in worse grip during ground ops, etc. Aircraft maintenance manager to inspect and repair or replace any damaged sub-component. The maintenance manager tracks per-airframe operating expenses in a realistic manner to show the real cost of operating the aircraft. Airframe manager that allows you to operate multiple simulated airframes, each with their own independently tracked wear & tear, livery selections and custom registration marks applied. Airframes can be automatically synchronized between multiple machines over the network with just a few clicks. This automatically syncs up aircraft position, configuration and wear & tear to simulate multiple users sharing the same physical aircraft. See how your fellow pilots treated the aircraft by checking the maintenance manager and engine trend monitoring outputs. X-Plane 11 G1000 avionics stack with lots of customizations and overlays to simulate the special extensions in the real TBM900. This includes a custom EICAS, systems synoptic pages and special integration with the extra simulated systems such as the weather radar, TAS, electrics, etc. Fully custom electrical system. Simulation of all buses, switching behaviors and reconfigurations. Full circuit breaker system, integrated with the X-Plane failure system, so a failed or failing system can pop a breaker. Highly accurate PT6 engine model with realistic startup and operating behavior. Engine lag, secondary fuel flow, ITT evolution, response to auxiliary load and many more fine-grained behaviors. Custom prop governor, with all modes simulated, including electric auto-feather with negative torque sensing. Crew Alerting System integrated into the avionics stack with all annunciations, takeoff/landing inhibits, flight state filters and "corner cases" simulated. Environmental Control System integrated into the custom EICAS. Air conditioning and pressurization respond in real time to environmental factors such as ambient temperature, pressure, available engine bleed air, cabin temperature setting, cabin pressure vessel failures, etc. Custom TAWS-B ground proximity warning system with all annunciations modes, inhibits, real-time impact point prediction and terrain painting up on the MFD to ranges of 200NM. The TAWS-B uses the X-Plane terrain DSF data to construct its database, so it is always "up to date". GWX 70 weather radar with weather & ground modes and realistic radar return painting. Full simulation of radar beam energy dissipation, signal attenuation when passing through dense weather and vertical cell analysis modes. Terrain mapping accurately paints surface features, including recognizable peaks, valleys and lakes. Supports the X-Plane 11 default atmospheric model as well as xEnviro. GTS 820 Traffic Advisory System (TAS) with aural alerts + visual alerts, the TAS MFD page and compatibility with X-Plane default traffic, PilotEdge, Vatsim and IVAO. Full simulation of the ESI-2000 standby instrument, including all configuration pages, sensor failures, AHRS drift and "roll-over" during extreme maneuvers, realistic battery operation and real-time battery depletion, etc. Dynamic custom registration mark paiting on the fuselage and instrument panel with support for custom TrueType fonts, colors and positioning. This lets livery painters make a "generic" livery and each pilot apply their own custom registration mark with just the click of a button directly in the simulator. Liveries can specify a custom position and font to optimize the look. Custom sound engine with samples from the real aircraft and accurate modeling of individual engine states and sub-component noises such as fuel pumps, gear pumps, flap actuators, etc. Just to start, we're including some work in progress screenshots below. Remember, work in progress means things are continually being added, both in 3D and programming. Thanks for stopping by!

  2. Yes the nose dropped quite significantly. The numbers in the data seems odd, though. The lift is on quite a high scale. Attached is a new dataset where I try (with questionable success) to keep the pitch (not AOA) steady. It is recorded with more datapoints to give a more precise analysis. The clock is too many for me to look into it. Will do tomorrow. Oh what the heck: Attached a coulple of extracts from the data. I am curious about the required amount of elevator input to keep the pitch. flight_data_w_AOA.csv

  3. Yeah with that drop in VVI around 40 ft AGL I’m curious if the nose pitched down right there. Nice job with the data btw. Do you also have the corresponding pitch (or even better AOA), and IAS data as well? As you probably know those are the determinants of lift.

  4. Yes, with ?excessive? back-pressure on the yoke I can also make a good landing. The above was done with N1 at ~51 % all the way to the ground (hence you see the hump in the charts), no thrust reduction, no elevator input to ease the landing etc. As such the pilot interaction is removed and what you see is the pure output of the equations from the simulator. As an added info (will add it to the original post): Gross weight: 45 tons.

  5. Hi Morten, Jan and all you other great developers of the B737, I have followed the ground effect discussion for years and remember the extensive work Morten put into it years ago. I also noticed your recent comments on the ground effect and that you believe it is within the ballpark. Not being a pilot I have no right to say what is right or wrong but within the last 50 feets, keeping a steady descent rate and speed, the descent rate increases rapidly and there is very little elevator authority within the last 100 feet before touch down. I have attached the data-file as a CSV (european separators). Also I have attached a chart with the last 300 feet plotting lift and drag over ft (agl). I have no knowledge of aerodynamics but a loss of lift in the range of 60.000 lb below 100 ft (agl) seems extreme, doesn't it? Had I cut the throttle I would have thought it natural but with a constant N1 of ~51 % I would have guessed it would drop a lot smoother before hitting the ground. The gross weight at landing was 45 tons and I was aiming at a vref+5kts of 132 KIAS. This is with IXEG B733 v1.21 and X-Plane 11.20b2. Best regards, Mikkel flight_data.csv

  6. Hello everyone, how are you ? I create this topic for a community request. I am a helicopter enthusiast, since the early beginning.. I never understood why in X-Plane, not any serious developer has ever thought of a great quality Huey. If just one helicopter should be choose among others, the Huey really should be that one .. It's simply the icon of helicopters. The Bell UH-1 Huey was intensively used in Vietnam War, creating the concept of using helis for troops transport and infantry support. Since, many versions were born, Bell 212, 412 UH-Y " Venom ".. but all that stuff is full of avionics, glass cockpit, autopilot etc .. The very first ones, the UH-1 B,C,D,H series, commonly called Iroquois,Slicks or even more internationally known as the Huey ( which came from it's original US Army name : HU-1A ), were very unique, every crew, pilots, engineer that had worked with " him " just loved him and never forget, always hold an important place in their hearts. That helicopter is first, deadly beautiful, American always got talent to make things that looks just sweet and naturally pretty, not like english stuff for example .. Every parts of it is pure mechanic, from main rotorhead to tail rotor, pure clever and reliable mechanic. And an other thing, maybe the most spectacular one.. it's SOUND ! Everyone one has obviously heard one, they are presents in EVERY US films. That sound was the " chance to get out of the green hell " for Vietnam vet's, and it still remains a certain charm nowadays, his big two bladed rotor made an exceptional sounds, it's like - for fixed wing enthusiasts - the sound of a big Pratt & Whitney radial engine, or F4U-1 legendary sound for example .. Very touching and affecting ... It's the first helicopter in X-Plane, that I see people request : - http://forums.x-pilo...e-payware-heli/ - http://forums.x-plan...showtopic=48423 Some were available for 7.XX X-Planer version.. very outdated now. Alfredo Fernandes and his own company " Dreamfoil's Creation " ( http://dreamfoil.xyz.ind.br/ ) was quite interested in doing one, but seeing how the X-Plane helicopter market goes, it could be risky. People are less interested helicopter because " It's too hard to fly " or " It's not as faster as a SR71 Blackbird .. " But I hope ( and believe ) that now, with X-Plane 10 incredible lands, city, neighborhood, backyards, supermarket etc... anyway, all the new X-Plane 10 ground live, people will want some birds to fly low, land anywhere, to explore that brand new world.. Helicopters are not hard once you got how it works, and when you got it, you feel a impressive pleasure of perfectly control a beast that anyone tell is hard to handle.. I would like to know with this topic, how many people are REALLY interested in the Huey, and who would be ready to pay for it. I really think Alfredo is THE guy for doing this, it's a perfectionist, he has already released two helicopters ( Bell 206 Jet Ranger III and Robinson R-22 Beta II ) outstanding ones, they were the first to benefits from a real 3D sound engine, with HQ sounds for every parts of the heli like blades slap, transmission, alternative wind, tail rotor, clutch .. all these sounds based on datarefs and how it react with what you are doing, how much blade pitch you input on, where and how much wind come to the rotor etc.. so not just good recorded sounds. And god know how the sounds are important in simulation, especially in helicopter. The very exceptional Huey sounds would benefits from that system ( Dreamengine exclusive plugin ). Then, the flight model was, on the R22 and Bell 206, pushed very far, tested with real aviation pilots, tweaked by Alfredo, re tested by pilots etc.. cheating with values, using plugins, constantly tweaking to get the most realistic experience as possible with what X-Plane 9.70 has to offer. The graphics were outstanding, some things like vibrations and shaking is a " must have " feature that every heli should have and so, HE IS the guy if you want an extra quality Helicopter. So, give your thoughts , if you are really interested in it, make this thread busy ! If Huey has the reputation it has in the real rotary world, it should have many people interested ! Best regards, Valentin
