PMDG 747 week 3 roundup

by

Welcome to week 3 of the PMDG 747 rebuild series. This week has given us some ups and downs. However, we made it through the week with some interesting changes to TFM. So, read on for some fun and potentially not so fun updates.

 

Changing the blog series name

 

Since we started the blog series on the PMDG 737, we have introduced new features and bug fixes not related directly to the 737. It is the same with the 747. We are introducing new features and fixing bugs not directly related to the 747. Keep in mind, we are still working on the 747. We are also working on things not related to PMDG aircraft. Given this, we are thinking of changing the series name to “TFM updates, week X” or something similar. If you have any other ideas, feel free to drop us a line on the contact form on the website.

 

What happened to Navigraph?

 

Some users might have seen the GitHub commits mentioning the removal of the Navigraph support in TFM. This is true. Navigraph has taken forever to get back to us about adding Navigraph support to TFM. Since they are taking forever and we aren’t using it anyways, we removed support for it. In the event we are able to make use of it, we will add it back into TFM.

 

PMDG 747 changes

 

Since we have been working in other areas of TFM, the 747 hasn’t gotten much attention. There are a few things to mention.

 

  • The Overhead Maint/Electrical panel buttons now work.
  • Added the Overhead Maint/Fuel panel, described below.

Overhead Maint/Fuel panel

 

This panel is self explanatory. It only has two buttons listed below.

 

ALT+S – Scavenge pump. Press SPACE or ENTER to toggle.

ALT+R – RSV 2-3 transfer. Press SPACE or ENTER to toggle.

 

While looking through the SDK, there are some controls or entire panels that have write-only controls on them. This means we can provide a setting, but can’t read the setting. These controls and panels aren’t much use to BVI pilots, so we will leave them out of TFM until PMDG can provide an outlet for reading the existing setting of these controls and panels. In the Overhead Maint panel, the following panels are left out of TFM until further notice.

 

  • EEC
  • EMU (748 only)
  • APU startup source (748 only)

Weather changes

 

Since we are working on other things along with the PMDG aircraft, we decided to start putting weather tracking into TFM. Adding weather is nice because we can add a few things at a time until the weather services are exhausted. Here are the weather events added this week. The below are added to the request wind command which will be renamed in a future release.

 

  • Visibility in knotts.
  • Turbulence level, none, moderate, severe, or extreme.
  • Precipitation level, none, light, moderate, heavy, very heavy.
  • Precipitation type, none, rain, snow, or hail.

We also added the ability for TFM to automatically announce when the aircraft enters/exits a cloud. The precipitation level/type will get added in a future release.

 

Bug fixes for this week

 

  • The PMDG 737 now only displays its own heading box. Previously, it would display the heading window for freeware aircraft instead of its own.
  • The rebuild database button in TFM’s airports database settings is now ‘build database’. Previously, it had the confusing name ‘rebuild database’.
  • The build database will only display if either P3D or MSFS is loaded into a cockpit. Previously, it would be displayed even if there were no simulators loaded. Pressing the build database button without a loaded simulator forced TFM to crash.

 

Other changes

 

  • Read instrumentation now works. Press right bracket (]), then SHIFT+M to toggle it on and off.
  • When using ‘Where am I?’ right bracket (]), then SHIFT+C while on a runway will now give the runway distance in feet.

 

What about the 737 comms panels?

 

We are still working on the comms/audio panels. There is a sequence of events we have to figure out to make the microphones and receivers change frequency type. We will keep everyone updated as things move along.

 

 

PMDG 747 week 2 roundup

by

Welcome back! Last week, we started rebuilding support for the PMDG 747. During the PMDG 737 rebuild series, the blog post titles got very long in some cases. During the PMDG 747 rebuild series, the blog titles will resemble this one: PMDG747 week 2 roundup. With that in mind, let’s get started with the PMDG 747 week 2 roundup! This post may be longer than most, but keep reading to find some interesting changes to the airports database, and the first panel to be supported in the PMDG 747.

 

Airports database

Why the changes?

 

The airports database structure has significantly changed since TFM 23.1, released at the start of January 2023. The new database design reduces the memory footprint of the airports data loaded into memory. When TFM starts, it loads the airports database. This database is over 3GB in size while it lives in memory. Each time a user requests information from the database, it calculates that user’s current location in relation to everything in the world. The resulting airports database takes up an additional 3GB of memory. To reduce the number of times TFM recalculates the user’s current location in the world, TFM constantly recalculates the user’s current location every 250MS. The consequence is that every 250MS, TFM eats another 3GB of memory. This forces the CPU to over work, pushing incomplete work on to the GPU, which eventually overloads. As a result, MSFS users experience audio buffering, jittering or jumping video, or significant lagging when the airports database is loaded. P3D users don’t experience these problems because the airports database is small enough to rebuild without taking up significant portions of computer resources. To make it easier to work with the airports database, all users will have the same changes to work with. Below are the changes made to the new airports database structure.

 

What’s new?

 

* When starting TFM for the first time, you must build the airports database.

* Start TFM.

* Go into TFM settings.

* Find the airports database section in the tree.

* In the airports database window.

* In the P3d airports database area, locate and set the P3D airports database folder.

* In the MSFS area, locate and set your MSFS airports database folder.

* Locate the “rebuild airports database” button and activate it.

* A message will appear, notifying you when the database is finished building.

* Press the OK button to close settings.

* Restart TFM by pressing right bracket (]), then CTRL+SHIFT+X.

* When TFM restarts, it will load the new database.

* Most TFM airport database features such as the ILS tracking system stay the same. We will announch any changes when they occur.

* Most airport database features run faster. A test of the ‘Where am I?’ feature accessed by pressing right bracket (]), then SHIFT+C significantlly improved in speed.

* Report bugs in the GitHub issue queue if you find any problems.

 

What’s missing?

 

* We removed the freeware flight planner. It requires a significant rewrite to comply with the new airports database design.

* We removed the airports search window found under procedures menu in the freeware flight planner. It requires significant rewrites to comply with the new airports database design.

 

PMDG 737 updates

 

The 737 isn’t quite finished yet. There are a few items that need finished. The audio/comms panels are taking a little longer than expected because we need to contact PMDG support for clarification on some of the controls. The FMC redesign is delayed because we are looking into what alternate design will work best. Aside from these outstanding items, the 737 is complete. If you have a special request for the PMDG 737, drop us a line and we will look into it.

 

PMDG 747 updates

 

Overhead Maintenance/Electrical panel

 

We added the overhead maintenance/electrical panel. This panel controls electrical activity in the engine generators and APU generators. It also defines how electricity flows from the APU and generators. As always, there is more than one way to access the controls in a panel. Either use the TAB key and move through the controls, or use the assigned keyboard commands, listed below. Since there are groups of controls in this panel, each keyboard command will take you to the group of controls linked to it.

 

Keyboard commands

 

ALT+G – Generator field reset switches. Group that contains 4 engine generator reset switches. Change by pressing SPACE or ENTER.

ALT+A – APU reset switches. A group that contains the 2 APU reset switches. Change with SPACE or ENTER.

ALT+S – Split system breaker. Change with SPACE or ENTEr.

ALT+N – Ground power test switch. Change with SPACE or ENTER.

ALT+P – Towing power switch (748 only). Change with SPACE or ENTER.

ALT+1 – Generator reset indicators. Readonly.

ALT+2 – APU reset indicators. Readonly.

ALT+3 – Split system breaker indicator. Readonly.

 

 

Other changes

 

The “Where am I?” feature has a new capability. In the past, this feature would announce the runway, gate, or taxiway where the aircraft is currently located when on the ground. In addition to these locations, “Where am I?” will announce the airport code if you are not located at a runway, gate, or taxiway, but are located somewhere within the airport’s geofenced boundaries. This helps identify when you are at the airport in the below cases.

 

  • You ran off the runway during landing.
  • You completely missed the runway during a landing.
  • You are landing on a runway that does not exist in your scenery.
  • * You attempt to drive around the airport and get lost.
  • * Pushback puts part of your aircraft in the grass or other surface.
  • * You attempt to taxi and run off the taxiway onto another surface.
  • * Other scenarios not listed.

 

It is our goal to give the “Where am I?” feature the ability to automatically announce location changes. This post is one of the longer ones we have written, so we will close for now. Until next week, have fun flying!

PMDG rebuild series, week 27: Control Stand, MSFS performance, close to the end

by

Welcome to week 27 of the PMDG 737 rebuild series. A lot has gone into the past 4 weeks, and we have a lot to cover. The control stand is finished, and we have some bug fixes most people will like. The fall 2022 survey is now closed. Thanks to the people who filled it out. We will post the results on Sunday’s blog post for week 27. Now, on with the new content!

 

MSFS Performance fixes

 

Many users have noticed that TFM will cause MSFS to buffer audio, drop frames in the video, and on occasion crash. The obvious problem is the airports database and its size. The default MSFS airports database is around 780MB on disk. That’s almost 800MB of text files! When loaded into TFM, it expands to around 2GB. For some reason, loading the MSFS airports database caused GPU overloads, dropped frames, and code matrix overloads. We implemented a fix for it. However, our testing is fairly limited to a few users at this point. To check if the problem is fixed for you, do the following.

 

NOTE: The following steps requires Open broadcasting system (OBS). So, make sure you have downloaded, installed, and configured it for an MSFS recording session.

 

  1. Start MSFS and load into a PMDG 737 aircraft.
  2. Start OBS and set up for an MSFS recording.
  3. Start the recording session in OBS.
  4. While recording a video, force TFM to produce problems. A common way to cause problems is open the cockpit panels with left bracket ([), then Ctrl+P.
  5. When done trying to crash MSFS or TFM, stop the OBS recording.
  6. In OBS, go to help>logs>upload and activate the menu item.
  7. In the logs successfully uploaded window, press the analyze button. A webpage appears with the results.
  8. Read through the results. If TFM is not causing problems, you will have no GPU or code matrix overruns.
  9. Close OBS.

 

It would help us if you would send us your OBS analyzer results, especially if it identifies GPU and code matrix problems. You can send the results to info at talkingflightmonitor.com. Note the @ is spelled out with spaces around it.

 

The PMDG 737 FMC slash key

 

The slash (/) key on the PMDG 737 is now fixed. This includes the P3D and MSFS versions of the PMDG 737.

 

Control Stand

 

The control stand is self explanatory, so we wont go into much detail about its operation here. However, we will go over the keyboard commands for each section. Most of these sections are split into groups to accommodate keyboard commands. All of these controls have the ability to be silent. Just go to TFM settings/PMDG/737 speech events/Control Stand to find the sections below. Check the box to have TFM announce the value when it changes, and uncheck the box to have it remain silent when the value changes.

 

CDU

 

  • Has no keyboard commands.

Have fun flying, and don’t forget the bug reports and feature requests.

Developer update 5/12/2022

by

In a short while, TFM 22.5 will release. This version has three major updates. The new features include a fix to the settings dialog, a setting to find the location of the airports database, and a new ILS system.

 

Settings update

In the past, the PMDG CDU soft keys setting in the PMDG settings refused to save. Going forward, all settings will keep the user’s preferences. We also added some new settings described in the following sections.

 

Airports database location

There is a new category in settings named airports database. When exploring these settings, there is a text field that accepts a folder path where P3D’s airports database is found. You will also find a browse button to aid in finding the required folder. This setting is needed in order for TFM to make use of airport functions. The new ILS system is one of those features requiring the use of the airports database.

 

New ILS system

The current ILS system is based on the aircraft’s navigation system. For example, NAV1 has a localizer needle that moves from left to right showing your position on the localizer. The same method occurs for the glide slope. When NAV1 is tracking the glide slope, the radio needle moves up and down to show your position on the glide slope. TFM represents these positions as a percentage value. For example, “99% left, 80% up”. It is difficult to understand the meaning of these values, so we rewrote the current ILS system to supply heading values for the localizer, and altitude values for the glide slope. For example, TFM might announce “40 left, 1500 below”. In this case, turn 40 degrees to the left for the localizer, and descend 1500 feet for the glide slope. Along with the new ILS system are two settings under aircraft in the settings dialog. The first one is ‘announce localizer headings’. When it is checked, the localizer will supply directions in the form of headings. The second one is ‘announce glide slope altitudes’. When checked, the glide slope will supply directions in the form of altitude values. When these settings are unchecked, the ILS system will revert to the original percentage values.

The new ILS system comes with a dialog opened by pressing the right bracket key (]), then pressing CONTROL+D. You must make selections in this dialog for the new ILS to work. When the dialog opens, focus is placed on the airport field. You can then type the airport code of interest, such as KMIA or KATL. When done, press ENTER on your keyboard. TFM should announce the number of runways loaded. Otherwise, it will announce that the airport is invalid. When you have the runways of interest loaded, press ALT+R to jump to the list of runways. Use the arrow keys to choose a runway. When done, press ALT+I to jump to the ILS information field. Review the details. If needed, revisit the runways list to make another choice, then revisit the ILS information field to review the details again. To revisit the airport field, press ALT+A, then type in a new airport code and press ENTER on your keyboard. When satisfied with your choices, press ALT+O for the Ok button. Otherwise press ALT+C to cancel and close the dialog. Feel free to make use of the destination runway dialog any time during a flight. As long as the settings are set before final approach.

 

Known issues

  • The destination runway dialog has no method of clearing current settings. To fix, load another airport.
  • The ILS details field in the destination runway dialog only gives essential information. Report a new feature to have more information added.
  • The distance lines in the ILS details of the destination runway dialog may give false numbers when on ground or before aircraft power up. This is a limitation of the database.

We want your feedback on any TFM features. To report a bug or new feature request, press the right bracket key (]), then press CONTROL+SHIFT+I to open the GitHub issue queue. Please look to see if your feature or bug has already been reported. If not, feel free to post a new report. Otherwise, make a new comment on an existing report discussing your bug or feature. To contact us about getting started with TFM, feel free to fill out our contact form. One of us will get back with you soon.
