New features in v93

[Apps4av Support]

The current build on GitHub for AvareX has created landing and takeoff distance calculations, girl consumption, cruise setting etc. And had combined aircraft and w&b with performance. 

These are some me major new features that need testing before general public release. 

Is anyone able to get latest release from GitHub and test ?

That's embarrassing. I guess I invented a new phrase in English. 

Correction - Fuel consumption.

I was wondering.  I mean, girl consumption is a known phenomenon associated with building an airplane, but not with the moving map. :)

I have it installed on my Samsung Galaxy S24. I do like these features and will test more. However, one important thing to note is that via the user.db export/import all of my aircraft data were lost. Is there any way to preserve that data, even though we're moving to a more sophisticated customizable POH idea?

See your aircraft under aircraft performance under self defined airplanes.

I haven't had a chance to go through all of the new stuff yet, but with W&B, when I tried to enter the empty weight it would let me click in the box, but wouldn't let me enter more than one number. And not let me enter a zero at all. This is with Windows 11.

Thank you,

David Farleman

What does the version say?

Working with V93 on Android now.

I've added my Aircraft (Custom tab) information, performance, and W&B, and hit save. When I close AvareX and open again, my aircraft is not in the list anymore. I tried it a second time thinking I missed a save somewhere, but same thing happened. After I get out of AvareX and open again, my aircraft is not in the list anymore.

Thank you,

David Farleman

[David Farleman]

Ok I started the Aircraft information again, but did not complete it. This time the aircraft saved (maybe user error the first time?). How do I get back into edit the aircraft I added to complete the information and performance? Choosing customize (the aircraft I added) it adds another aircraft again with the same tail number, but adds a "2" at the end. Then if I choose customize again to add more info, it saves the tail number again, but the next save has "22" at the end. If I keep going it just keeps adding an additional "2" at the end.

Thank you,

David Farleman

Performance Criteria:

How is the performance data interpolated with altitude and temperature in AvareX V93? My performance charts are Density Altitude (y-axis) and Takeoff Distance (x-axis). Trying to figure out how to approach adding the performance numbers with Density Altitude from my POH.

Thank you,

Sorry for the delay. 

To be more specific, I had made sure to export my v92 user.db prior to installing the v93 apk. I'm pretty sure in the past this file preserved the W&B data for my aircraft. Importing this user.db doesn't seem to populate anything under the "Custom" tab in "Aircraft & Performance". Is there another place to find the imported aircraft? 

I raise this issue because I fear it's possible that people will be losing their W&B data in the update from v92 to v93 (which appears to now be live on the Play store). 

It may be that it was too hard to migrate the legacy W&B models to the new functionality. Or maybe this migration occurred when the app update happened, but it didn't follow me via the user.db? 

In any case, I suppose I'm fine to just rebuild all of my planes, since I think this represents some significant improvements to the functionality and is a welcome change regardless. 

[Apps4av Support]

You are right, the W&B data has been moved under aircraft so it needs to be entered again. The rest should be there. Can move w&b back, but then it will be independent of the airplane which is odd.

I will add DA for guidance. You will need to play with temperature.

Zubair, I noticed two issues with the new W&B screen in v93. My custom aircraft has 10 weight stations. 

Issue 1: I save them all ten (10) weight stations and navigate away from the W&B entry screen to e.g. the map screen. Later I return to the W&B screen but only six (6) rows of weight stations are being displayed, their customized station names have been replaced by the default names of the Cessna 172 sample airplane, and the totals are wrong.

Issue 2: Continuing from the previous W&B screen (Issue 1), I now temporarily change aircraft to a different model from the top-right dropdown list, then immediately switch back to my custom aircraft. The W&B now displays eight (8) weight stations, including some (but not all) of my custom names. However, two (2) of my rows of weight stations remain missing, along with some of the custom names previously entered.

[McGregor]

Hey, David,

I think you'll need to go backwards to simulate a few temperature / altitude pairs from the density altitude. You could implement the relevant formulae in a spreadsheet or some kind of programming language to make that process much faster. If there's enough interest, I'd be happy to help implement that in javascript (I have done this in the forward direction for one of my own projects). 

The only alternative I can think of would be for AvareX to implement a secondary UI for this, which sounds a bit convoluted. 

I hope this helps.

Zubair, I take your point that re-importing W&B data independent of the airplane is odd. 

More generally, I'm curious what your thoughts are on the default list of airplanes. Did you pull a list of the nine most common models? Do you plan to expand or update this list? 

This may be an unreasonable proposal, but I can imagine maintaining an expanding dataset of model defaults that can be pulled into your device via the "Download" page. I think this could be nice because you'd only have to navigate through, say, forty models on one page, once. Most of the models listed on the "Aircraft & Performance" menus are irrelevant to me, and my typical use case will be to select from my custom planes—not from the defaults. Also, I'd love to share the Mooney M20C data I just spent two hours compiling so no one else has to!

I definitely understand that maintaining a non-finite collection of community-sourced performance data could be a real can of worms. Just curious if you had any intention of going down that path. 

P.S., more actionable feedback for this thread:

1. I'm also seeing funky W&B behavior when navigating away from a recently updated aircraft. 
2. I think it would be much easier to add performance data if each new line added defaulted to the data directly above it (e.g., ideally I don't have to keep typing altitude="5000" for each of my POH's 17 entries at 5000 ft).  
3. I do think the update / save workflow on the "Custom" page is a bit awkward and error-prone. When entering my Mooney data I kept wanting to save progress in case the app crashed or something, but this essentially meant following a workflow like "N12345" -> Save -> "N123452" -> Save -> Delete "N12345" -> Customize "N123452" -> "N12345" and repeat...
4. I've always thought the blue dots on the "CG Envelope" were a bit odd and imprecise. Is there a reason we can't use some kind of UI to add points precisely and iteratively?

As always, thanks for all the new functionality, and I hope some of this feedback is useful!

[David Farleman]

Hi McGregor,

Yep, thinking along the same lines as you. I'm going to throw a quick Excel spreadsheet together to give me what I need for the performance data. 

Thanks!

David

Only issue with the "nine most common aircraft" is that probably doesn't even scratch the surface of what might be used or useful.

Take the Cessna 172, there are probably 20+ variants. A, B, C , all the way through S.

Next you have the Cherokees, PA28-140, -150, 161, -180, -181, -236, -236, PA28R-200, -201, PA28T-201 and then within those you have various sub-models.

A good example of differences in the Cherokee line, one of the planes I routinely flying is a Piper Arrow, PA28-200, at first blush you'd think it would be the Arrow II, it has the Hershey bar wing and a 200HP engine, however you'd be wrong, it is actually a "200B".  What's the difference you ask? It has the same wing and engine as the Arrow II.  The difference is the length of the fuselage, the 200B has a shorter fuselage.  I'm not sure if Piper made a "200A" or if that would have been the "180" which was the PA28R-180.

My point is there are so many variants it is really up to the user to create the appropriate entries.

What might be a better option is to have a users create the data for their specific aircraft model and share it so that it can simply be imported (and modified if necessary) by somebody else flying the same model.
