  2. Altimeter bug?

    in TBM 900

    Posted

    Hi guys,

    Can you take a look at this screenshot? It's from EGPB with ActiveSky XP running (QNH 1033). I also try to revert to the default CAVOK XP default (without Activesky XP running of course). The standby altimeter is completely off, showing 39000 feet approximately, at sea level.


    Kind regards

    Hi Goran,

    I am trying to find tbm900/controls/engine/emerg_power. But I can only find "engine" under "actuators". And there it is only "friction lock". See attached screenshot. Maybe I am just looking in the wrong place.. could you help me by pointing me in the right direction? I'm using version 1.13

    Kind regards

  6. Propeller RPM (Np) issue

    in TBM 900

    Posted

    Hi everyone,

    It seems that X-plane default failures was enabled, even though nothing was really set as "Failed". Disabling XP default failures and just press "fix all" seemed to solve the issue with the prop having a hard time unfeathering.

  7. Propeller RPM (Np) issue

    in TBM 900

    Posted

    Hello,

    I am using version 1.13 for the moment. Yesterday, I did a short flight with a brand new airframe and all components in an excellent shape (looking at the maintenance manager).

    Today, I left it on ground power for a while to familiarize myself with some systems and procedures. So, after a while I decided to try and start up to do a short flight. I had a normal start, and then I disconnected the GPU and put the generator to MAIN. But, when I put the power lever into flight idle, the propeller should unfeather and stabilize well above the yellow band. But in this case, the propeller would not accelerate beyond the yellow RPM, even with the power lever placed in flight idle. I tried a couple of times to feather (HI IDLE and LO IDLE) it, and then unfeather it again. So, I shut down and check the maintenance manager. Every component ok. Never seen this behaviour before. Any clues?

  10. PFD and MDF anomaly

    in TBM 900

    Posted

    Hi,

    I can confirm that I don't have any external avionics hardware. I only use a CH yoke, CH TQ and Saitek rudder pedals.

    Anyway, after re-starting x-plane the screens went back to normal.

  11. PFD and MDF anomaly

    in TBM 900

    Hello,

    After buying the hotstart TBM and doing some flights, the PFD and MFD went crazy, I lost most of my indications as you can see on the screenshot. I managed to land visually and after shutting down completely I checked the maintenance manager - everything under avionics was "like new". Could this be a bug or something?

    And, I also tried to power up again, but the condition persisted.

  12. Performance Calculation

    in General Discussion

    Posted

    23 minutes ago, joers182 said:

    Toper is alright but 80% of the time it just gives me a derate of 67 for a flap 5 take off.

    But be aware that when selecting "737-300" from the menu, the software assumes 22K of thrust. The IXEG 737 models the one with 20K engines. So in TOPER, I select the 737-500, because the 500 in TOPER is based on the 20K engines. Even though not entirely correct, performancewise in the sim, I would say it makes little difference to choose another airframe. 

    On the other hand, try to enter an airport with a fairly short runway (around 2000 meters or so), and TOPER will warn you if you try to enter near or at maximum takeoff weight (approx 63.2 tonnes for the 300). I also tried reducing the weight a little bit (still close to structural MTOW), and TOPER suggested around 33 degrees C assumed temperature.

    I did one test at ENHD (Haugesund airport, on the coast of southwestern Norway). The runway is approx 2000 meters, I topped the plane with payload and fuel so that the takeoff weight was around 58 tonnes, which was the highest weight TOPER allowed me to have with an assumed temperature of 33 degrees. I cannot remember the wind, but the OAT was around 20 degrees I believe. Flaps was 5 degrees (TOPER does not provide calculations for flaps 1 takeoffs).

    I then used X-plane's default failure system to initate engine failure just prior to V1. When the engine failed, I immediately retarded the thrust levers to idle. The autobrake kicked in with RTO and slowed me down to a stop just a tad before the runway end, but still with some meters to spare. Note that I did not use ANY reverse thrust at all, and no speedbrakes either (to put extra weight on the main wheels). Still, it worked out fine. I would say, that if TOPER was giving me the wrong data, I would probably have made my way into the geography beyond the runway. I'm also pretty sure that the accelerate-stop-distance (that is, the distance the plane would use to accelerate to V1, experience an engine failure, and then come to a complete stop), is purely based on brakes only, and not taking thrust reverse into account.

    I also did the experiment on other shorter runways, and coming to a stop after an engine failure near V1 was perfectly manageable using RTO on autobrakes only. I encourage you to experiment a little bit with this. And don't choose the longest runways, because here, the structural takeoff weight will always be limiting, no matter what.

    One limitation I can see with TOPER so far, is that it always wants to calculate the highest possible assumed temperature for any given runway, wind, OAT, pressure and weight. For instance, the program might warn me if I want to takeoff from a 2000 meter runway with 61 tonnes weight using an assumed temperature of 30 degrees C or more. But, taking of with full thrust from the same runway might work fine. At least, that's my opinion so far.

    There are a number of factors that determine the maximum allowable assumed temperature, as well as the maximum allowable takeoff weight for that assumed temperature. One good place to read about assumed temperature is the B737 Techincal Site (maintained by Captain Chris Brady of Easyjet).

    http://www.b737.org.uk/assumedtemp.htm

    Also, the difference between assumed temperature and de-rates are also well explained.

    Happy landings :)

  13. [1.0.5] derated takeoff - thrust mode display

    in Bug Reports

    No, there is no D-TO to my knowledge. Checking the thrust rating on the CDU is essential to avoid having the wrong "max thrust" selected. On my airling, a derated thrust was never used, not sure if other airlines even do that...

    The effect of R-CLB washes out to 15.000 feet, but I am not sure if the label will change from R-CLB to CLB... something I never consciously watched in 10 years of flying the plane. Simply don´t know and the manual doesn´t state it clearly, either.

    That's great Jan :)

  14. [1.0.5] derated takeoff - thrust mode display

    in Bug Reports

    Posted

    Hello,

    But shouldn't the thrust display readout show something like (D-TO) if a derate is selected (like shown here) ?

    I have noted that when using an assumed temperature during takeoff, the display on the engine instruments stay at R-CLB all the way up to crz level. I thought that the thrust mode display would switch to CLB when passing 15000 feet or so.

  15. Bug in terrain display

    in Bug Reports

    Posted

    Hello,

    There seems to be a bug in the terrain display. When choosing normal map mode (expanded map), the terrain seems to draw fine. However, when selecting the MAP CTR mode, the minimum and maximum elevation figures are displaced out of view.

    Location was ENGM (lined up on RWY 01L)

    Please see screenshots.

    Also a question: On the screenshot with expanded mode, the lowest elevation figure reads 006. I assume this means the lowest elevation within the selected map range is 600 feet. Is this correct?

  18. Logo lights aren't working (No winglets)

    I run X-plane 10.45 with an i7 3770k, 8gb ram and an Nvidia GTX 480 card (really outdated videocard!), with HDR turned on. I'm sceptic to the claim from Muskoka that HDR on causes a drop in FPS from 25% to 40%. I'm sure there are many other ways to improve X-plane performance. I think Muskoka's post was inappropriate and rude, considering that no valid argument could really be presented. Looks more to me like pouring gasoline on a fire. I just felt I had to react to such a post. Enough said for me. Keep up the good work IXEG team !

  21. HDG select turns on when pressing TOGA

    in Bug Reports

    Posted · Edited by kyrre1978

    Hello,

    During my last few flights, HDG SEL roll mode becomes active upon pushing the TOGA button (X-plane default button).

    I'm pretty certain i didn't touch the HDG SEL button on the MCP prior to taking off.

    There's nothing really wrong with that, but I thought this feature only worked on the NG's. Is this the correct AFDS behaviour during takeoff when using TOGA?

  23. Stabilizer trim runaway after takeoff

    in Bug Reports

    Posted

    Hello,

    Today I did a regular flight. Shortly after takeoff, I was trimming a little to adjust for V2+15 (using the standard elevator trim button assignments in X-plane).

    As I was trimming the nose down a little, the trim continued to work it's way all the way to the maximum nose down position. Shortly thereafter, the trim went crazy the other way around (full nose up). I tried to counteract with the assigned trim buttons on my CH yoke, but to no avail. In the end, I wasn't able to sustain control anymore, resulting in a stall (deep stall) and subsequent crash with mother earth :(. During the struggle, I also tried to move the trim wheels manually, but they refused to respond and continued towards full nose up. The only thing I didn't try, was to use the cutout switch on the TQ. I know this may be hard for you to reproduce, but I thought it might be useful for you to know anyway. Definetly not happened to me before! 

    A short summary of my setup:

    Route: ENAL - ENBR

    Weather: FS Global Real Wx with Real Weather Connector and Skymaxx Pro V3.1.1

    Other plugins installed: XUIPC

    I'll try another go now.

    On another flight, I also had a bird strike during taxi (causing a fire in engine 2). The rendering option to draw birds and deer during nice weather was turned on.

    I shut the engine down, used the fire bottle and taxied back to the gate, then choose Gizmo reboot. After that, the right engine would not start, N2 just spiked at around 40%. Introducing fuel didn't help. I found out that restarting X-plane did the trick that time.

    Best regards,

    Kyrre Andersen
