MU-2B-60: using SPZ-500 APR Mode

Recommended Posts

Hi there,

 

I like the AC very much, so thanks very much!

Three questions:

1. I tried to shoot an ILS approach at Bowerman rwy24. I thought that I had everything set up for the approach. I hit the APR button on the AP but it wouldn't come on. No APR light and no activation of the APR mode. Did I do something wrong/missed something? Perhaps you can refer me to a resource on the SPZ-500 as I only found non free resources or make a video on it's use?)

2. The inertia felt on departure and approach (slow speed phases) is that due to the tip tanks (when full?)

3. How do I run the NTS checks on the MU-2

 

Thanks!

Rob 

 

 

PS found a nice resource on the MU-2:

Hi Rob -

 

1. I have the same issue...light doesnt come on. I also cant turn off the F/D once it's been turned on.

 

2. Are you experiencing excessive wing dips upon touchdown?

Hi Dave,

 

No wing dips here, only a kind of 'wallowing' in the air. Wing dips is problably due to the gear araangement (narrow track) and (excessive) asychronic power (e.g. because of going into beta but not at the samen time/slight delay for one engine)?

Hope this info helps!

 

1. If your getting no light on the mode selectors you need to turn on the Autopilot unit that is located on the floor below the throttle quadrant. I just loaded my APP saved flight and it's working fine and have not received any emails from customers on this issue.

 

2. I will let Joe answer this question on the inertia issue. The tip tanks do carry a large amount of fuel.

 

3. NTS Check: Push the right "UNFEATHER" button in and you should see a "RH BETA RANGE" light turn on. Now press the right starter button and the light should go off. Once your RPM is at 20% the light will appear back on and then go off at 50%. This means the NTS check passed. Once the RPM gets above 60% or 65% the light will appear back on only if the throttle lever is in ground idle position. This light has 2 modes and just lets you know your throttle is at the minimum position.

 

4. FD is turned off only when all AP modes are off or you can simply click the "SBY" reset mode. Due to FSX internal coding some modes will take like 20 seconds to turn off the FD. Most of the mode selectors will turn off the FD asap. 

 

To get the best taxi performance we suggest getting "FSPS Frictionality" payware addon. Also i heard FUIPC has a freeware addon that does the same thing but have never tested it and not sure if you need to have a registered version.

1. F/D modes SHOULD work without the need to have the A/P turned on (for use during manual flight guidance)...but they do NOT work, especially APP mode...some other modes work but not all the time...check the other threads about this.

 

4. None of the mode selector buttons (including the SBY button) will turn off the F/D cue on the AI.

 

Weird, it's as if you're using a completely different airplane than the rest of us. Please upload a video to Youtube showing #1 and #4 working correctly.

...won't let me edit my post above...just wanted to correct #4 above...the SBY button does turn off the f/d cue on the AI, but it often doesn't work as expected. Sometimes with just Nav mode enabled and after landing the SBY will not remove the f/d cue...ill sit there and wait a full minute and nothing, doesnt work...then maybe after im done viewing the replay it'll be off finally...it's either a bit unreliable or it could be that it's intended method of functionality is not clear to me. Yet othertimes it removes fine...can't seem to make heads or tails out of it.

 

#1 still stands...f/d app mode should work with autopilot OFF while in GPS mode...such as when manually flying a gps LPV approach for example. It seems to follow the lateral portion but im not sure it's following the g/s, and it doesnt light up to let me know if its captured or not.

Yes i just did some major testing and found a issue. And the FD will work with the AP off. I was saying you just need one of the mode selectors on. Does the yellow part in the middle of the Attitude indicator work as a FD in manual flight guidance? Because the FD is only going to sit on top of it and do nothing without a AP mode active! But i did notice if you use the HDG mode with autopilot off the FD will bank until you align the bug!

 

Here is the issues i found:

 

1. The APP light seems to be stuck on capture no matter what frequency is active. The mode is not active but i need to fix the code for that light for the FD to turn off. This is why it gets stuck. Will work on this issue this weekend!

We can talk on TS later about this Mark, but I just want to explain this from a real world pilot's perspective so there is no confusion.

 

The FD will always work with or without the autopilot engaged. All modes on the mode selector will work without the autopilot engaged. When the AP is off, the FD simply displays what the autopilot WOULD be doing if it was on. In other words, it shows you what pitch/roll inputs are needed to achieve the results dictated by mode selector inputs. Whether or not the AP is on or off is irrelevant. The FD will still display the info. It's just a matter of who's going to fly the airplane; you or the autopilot.

We need to sit down and do some testing as i noticed the FD will only follow the heading bug with the AP off. And a few other people emailed me with this issue as well. For example the FD will not follow the altitude setting with the AP off from the last time i tested. I could be wrong!

REV 1.6 Updates:

1.Ability to hide green plastic tint
2.Updated engine sounds
3.GTN750 now has case hotspot for 2D popup
4.Updated flight dynamics

5.Updated installer for steam edition
6.WX500 weather radar works using the GNS and GTN models. (Now only 2 models with all features available. Rather than having 2 static models and only 1 working model with no ability to control the night textures we decided to make both versions have better night textures with or without owning the product but the knobs will not animate due to fact we do not have the XML coding. Overall this gives you more options with less models and better night textures minus animated knobs.)

 

-----------------------------------------------------------------------------------------------

 

GTN 750 & GNS 530 INSTRUCTIONS:

 
GPS system:
1.When using a flight plan you must be within 2 NM of the waypoint course or when using Arrival and departure. If you decide to do an approach using the GPS system select the AP NAV mode since the Glide slope is a visual only and this mode will only hold lateral. The GTN warns you when you select this type of approach and it's for visual only. Best to switch to the Nav system for approaching.
 
NAV system: 
2.When in AP NAV mode tune in the navigation frequency to the next VOR. When ready to approach an airport select AP APR mode for ILS approach or AP APR/VOR mode for lateral approach only. These modes will capture when the CDI needle starts to move and will disengage the altitude hold modes once the glide slope is centered. 
 
3.If your flying a flight plan or holding a navigation VOR or using AP HDG mode and about to intercept an approach keep the AP NAV mode active and press the APR or VOR/APR. Once you intercept the AP NAV mode or AP HDG mode will disengage automatically.

With 1.6 the f/d nav issue is still not working correctly. I have no idea why you seem to be having trouble with it since it works fine in the C441.

 

Please just let me me refer you to Joe's post about it here as I cannot think of a better way to explain it again:

http://forum.avsim.net/topic/467712-mu-2b-60-using-spz-500-apr-mode/?view=findpost&p=3231852

 

In that post I believe he is talking to you, Mark...perhaps you missed it.

 

Currently the only way to get the f/d to follow the nav mode is to have the a/p on, or turn the a/p on and off...BUT, the correct way (just as in the c441) is that the f/d should follow the nav mode WITHOUT having to turn the a/p on.

FD is working for me. I have the AP unit off and I have the nav frequency in the gps unit set. And make sure your in Nav mode and not GPS mode. I did not have to turn the AP on then off so let me keep testing and see what is going on!

 

Update: Since you do need to turn the AP on and then off then there is a conflict in my code for this type of mode selector. Will work on this today. Thanks hangar.

 

Update: Found that you can press any lateral mode selector first then press the nav selector and it works. But so far if you just press nav with AP off it fails to work. Code seems good but still working on a solution.

Update: I fixed the issue for the nav with AP off so the FD now engages. The reason it was not working was it was using the mode button code like the others but for some reason it would not use it so i simply replaced that button code and used the actual nav variable and it works perfect.

 

I also was thinking about updating the AL/SEL with VS and IAS modes. I found there is no reason to have the VS or the IAS light turn off once captured. And i removed the 800 ft climb from the cfg so you must change the ap pitch wheel manually once your ready to climb or decend. This way you can change the alt sel setting and remain level. I also noticed if you turn off the VS or the IAS mode and the ALT/SEL mode is still on it's active. This will no longer be the case as you must have the VS or IAS mode on. And now that there is no default 800 ft pitch setting i must create another code so the go around button will set the pitch wheel to 800 ft climb. Just finished testing and the altitude modes are working excellent!

Thanks for working on this Mark...please check it using the GTN750 with a flightplan (direct point A to point B is fine to use as a test). make sure you're in GPS mode and then use the nav lateral mode to try and get the f/d to intercept the line. You should find that it only works if you first turn the a/p on and then off.

 

Thnaks again...if you need me to test or help you in anyway just shoot me an email and I'll be more than happy to help if I can.

Just tested the FD using the GTN750 in GPS mode and it works with my new fix.

 

I forgot to mention above that if your using the IAS hold with my new update the IAS will turn off and the VS will turn on once altitude is established.

 

The go around will not set the pitch wheel to 800 ft. as that is not real. It will disengage from holding an ILS approach and have the FD on so you can fly by hand to the last altitude setting.

looking forward to trying it!

 

Do I wait to see a v1.7 or should I just re-download 1.6?

I will re upload rev 1.6 but will post here when ready. Working on engine sounds with stereo balance for each engine and need to fix the steam edition link. Do you have steam edition and does the installer find it?

...sorry Mark, I use the regular boxed boxed version of FSX. I purchased SE last Christmas but it's not setup and in fact I've never even started it, so I'm not sure I would be the right person to ask. I can try to see if it'll install for you into SE but since I never started it Im not sure if the correct registry entries are even in place on my end.

 

Ok, no problem re:1.6 re-upload...I'll wait until you give the ok. I'll be around tomorrow eve again. If you need anything before then you can send me an email or try IM'ing me here.

Rev 1.6 just got uploaded again to the Flystore and is ready to download. I am holding off sending out our newsletter until Monday once i know this update is okay. 

 

Just fixed the FD for the nav mode as it was only turning on if you hit another mode first or turn the AP on then off. My coding for all the other modes used my custom buttons but for some reason the nav button would not respond. So i simply used the variable and the FD came to life any time you engage the nav mode selector. I aslo noticed that the VS and IAS light would turn off when captured. My new update the VS and IAS stay on since this is what makes the altitude lock active. But if you use the IAS and you reach your desired altitude it will auto switch to VS mode once captured. I am updating the manual with more info for the AP mode panel. I also updated the engine sounds today with stereo  sounds so left engine plays more toward the left speaker and same rule for the right engine. Improved the exterior sounds as well. There is still no way to fix the bug the air file has so when you quickly reduce power to idle it will drop the sound to 70% rpm for 3 seconds. So just try to lower the throttle slowly.

I'll give it a shot and post back tonight to let you know how it goes. So glad to see that you found the nav problem and thanks for also fixing the IAS...I noticed that it wasnt functioning yesterday during my testing and didn't want to add anything more onto your plate...so that's great, thank you!

 

Yea, too bad about the sound bug...but I dont recall it doing that in v1.3 when you used Dave's sound fix initially. What about using prop inertia setting, would that have any effect by lowering its inertia? (trying to think how to get it to not fall below 21 torque when coming out of reversers when condition lever is in full position. Probably not, just a stab in the dark.

 

***Edit: ok, had some time for a quick test this morning...manual f/d in nav mode is now working, woohoo!! Did a few short hops and it worked everytime :Applause:

 

Thank you, Mark...very nice!

 

On a side note, not really sure why you decided to engage vs mode when reaching alt...but in any case that seems to also be working as well, so yay :Big Grin:

 

Oh, I forget what the code fix is to get the f/d and a/p to follow the GPS's glideslope but Bert Peike has made it work with the Carenado planes while using the gtn750...haven't looked at that code in a long time, but if you contact him with an IM he'll gladly send you the mod fixes so you can see how he did it...or maybe he can just tell you without even having to send any files. I don't believe the fix is too difficult.

I did not change the IAS as it was always working. But it will change to VS mode once established. The reason for this is the default hold altitude lock mode is the VS and if the IAS mode stays active once you reach your altitude it will continue to pitch if you change your speed in the aircraft. But in VS mode you are stable and can continue holding altitude and decide what to do next. I can do some testing today to see what happens again if the IAS mode were to stay active once established.

 

Yep the FD using the nav mode selector is now alive....

 

The new sound cfg is Dave's settings. I just re wrote the layout with more entries for left and right engines in stereo and cleaned up entries that used no sound files. And what i mean about stereo is the left engine has it's own sound with more sound on your left speaker and the right engine has more sound on your right speaker.

 

You can use the FD and APR mode using the GTN750. Just switch from GPS radio to NAV radio! By default the FSX approach code will not hold an ILS using the GPS radio only NAV radio.

 

Today I will start some testing on the IAS mode and see if we can just keep it active once you reach your altitude.

All sounds good Mark...gonna try using nav instead of gps as you suggested for the gps approaches :BigGrin:

 

Regarding the IAS mode...I wasn't suggesting that you change it or that you make it stay in IAS mode really since you have it working ok now...BUT...what about making it like one would expect, where after reaching altitude the IAS/VS modes get turned off and only ALT mode stays on (which is supposed to hold the alt)?

Just tested and the IAS mode and it does not need to swap to the VS mode. And you make a good point as i had the VS and IAS lights turn off and the ALT/SEL mode stay on. I just did some more testing and going to put it back to what i had.

well to be honest the correct way of doing this (in fsx anyway)...is to have only the ALT mode stay on once reaching your altitude...that is what should hold your alt...and IAS and VS should turn off at that point.

 

BUT, the VS wheel should not activate UNLESS the pilot presses the VS button first. It's ok if the vs number goes up and down as you scroll it, but the plane should not climb/descend until the pilot re-engages altsel mode (and then either vs or IAS).

 

This is basically how all fsx 3rd party planes function in fsx...not all but the majority do work this way. Sounds like you just need to figure out how to get the vs wheel setting to be ignored by fsx until after the ALTSEL & vs/IAS button is on.
