  1. Would never have known about this without your post Glenn so thanks. Makes you wonder how many other little nuggets of gold lay undiscovered out there!
  2. I had the same message yesterday Andreas (in Australia). Restarting the PC fixed the issue. Strange though.
  3. Available over on flightsim.to is an amazing version of Doha airport, including city scape. https://flightsim.to/file/14639/doha-city-and-hamad-airport-v2-wip Need 3 extra of files to have it display as intended, and they are linked in the download. Well worth it.
  4. From MSFSAddons, https://msfsaddons.com/2021/05/04/britten-norman-bn-2-islander-coming-soon-to-msfs-by-black-box-simulation/, within days apparently!
  5. I agree Chock. I hope they bring the Navajo to MSFS. I found that quite good in P3D and if they stick to what they're doing in MSFS it would be a welcome addition. Most of their steam gauge stuff was pretty good.
  6. Yep, you can Ryan. In fact you can move in any direction. The disc (the main rotor) doesn't know which way is forward! To it, whichever way it's moving is forward, so yes sideways, backwards is just as effective. The thing is, when in VRS, the controls become very sloppy. When you move the cyclic in the direction you want to go, initially nothing happens for a few seconds (which feels like an eternity when you do it for the first time!). Eventually the little directional vector you do have will move the heli into clean air. Forward is obviously preferable because it offers the best vision. Cheers.
  7. We pretty much do an autorotation EVERY landing when with students past a certain level of experience. It's so important to develop the muscle memory so it by-passes the mind as much as possible. You don't have much time to make the correct actions if the engine goes in a heli (in a Robinson R22 or 44 you have about 2 seconds before the situation becomes unrecoverable). A lot of fatal accidents in helicopters due to engine failure, and fixed wing too, is down to the pilot not wanting to accept reality that this is happening and you'd better take action NOW. I'm sure you know this only too well SD with your fixed wing students. Pilots wait too long before taking corrective measures, resulting in loss of rotor RPM, which at a certain point is not possible to regain. You're a passenger at that point. We start by selecting a landing point, then establish ourselves at 75 kts (this is for Robinsons) and at least 800 ft agl to give the student time to set it up properly. We get the student to call when they think they should enter the auto so they get an idea of how far it will glide at different altitudes. We then initiate by lowering the collective fully, then rolling the throttle off. This will split the engine and rotor rpm needles. We aim to maintain 70 - 75 kts and keep the rotor rpm in the green arc. This is controlled by collective (increase / decrease pitch). Approaching the landing area, gentle rear cyclic and up collective is used to slow the forward speed and decrease rate of descent. At the appropriate point a small forward cyclic check is needed to avoid a tail strike and level the skids. Rotor rpm will now be decreasing, however if you have done it right, you will still have enough to control the descent and touch down softly. In training, I get my students to terminate into a 5 ft in ground effect hover, then I roll the throttle on and let the governor stabilize the RPM's. I do demonstrate a 'to the ground' auto for them and have them follow me through on the controls. As far as real life engine failures vs practice, I tell my students that if it happens to you in reality, screw the rotor rpm green arc and get as much energy into that rotor head as you can, especially before touch down.
  8. Are you talking about vortex ring state SD? If so, this occurs when you essentially descend into your own rotor down wash. This can occur with decent rates between about 800ft/min to 1500ft/min (these can vary though depending on weight, density etc), and forward airspeed less than 15-20 kts. The recovery technique is to lower collective (to remove angle of attack), and apply forward cyclic to gain forward speed, which will take some time and a lot of altitude as the rotor moves into clean air. You can see the issue here. The conditions for VRS mainly occur during landing phase, where you typically don't have the altitude to recover. I'm a heli CFI and we practice VRS recovery with students at altitudes above 4000 ft agl. We bring the heli to a hover and initiate a decent with collective. Once we have a decent in the range mentioned above, I get the student to raise collective to arrest the descent. This increases AOA, resulting in greater down thrust, resulting in more down wash. Rate of descent then rapidly increases. The more collective you pull to try and stop it, the worse the problem becomes. It's not uncommon to reach descent rates of 4000 ft/min plus. You can see why altitude is the only savior once this occurs (and proper recovery technique!). If you need to descend quickly, you can do so at high rates as long as you have a forward speed of 30 kts or more to ensure the rotor is in clean air at all times. Hope this helps?
  9. You hit the nail on the head there Kroswynd. That's exactly what I'd done and had completely forgot about. Thanks for your help.
  10. Apologies if this is a well known issue and I've somehow missed it, but I'm finding some graphics settings are not saving and are having to be reset on each sim start. Namely, vsync, depth of field, bloom and lens flare are not saving. Once reset to what I want, I hit apply and save and they remain like that for the duration, however when I relaunch the sim, they have reverted to the opposite setting. Not a big deal, but it is annoying and I just wanted to know if others have this problem also. Thanks.
  11. On Simmarket priced at 29.74 euro excluding VAT. Came out quicker than expected. https://secure.simmarket.com/nextgen-simulations-bandeirante-msfs.phtml
  12. Just curious as I'm looking at upgrading my entire system..... is anyone using an RTX 3060 12GB with P3D V5? If so, how are you finding it when it comes to VRAM usage?
