E-Jets Update 0.9.4
Dear Supporters,
Due to the stutter issues with our last update, we are currently focusing on improving performance. At this point, it would not make sense to implement new features until the performance is at an acceptable level. Accordingly, this release contains only bug fixes and a few improvements.
By now we know pretty well why the performance is so bad. To put it simply, the rendering in the JavaScript/HTML combination is causing us problems. This is always the case when values change. You can see this most clearly in the PFD. As long as the plane does not move, everything is fine. But as soon as values like speed or altitude change and therefore have to be updated on the PFD, the stutters start.
This can ultimately only be solved by switching to the WASM/NanoVG combination. However, this is easier said than done. C++ is more complex to code and JavaScript is not easy to convert. You can’t run a „Google Translator“ over it and get your code in another language because while the human brain can interpret even grammatically wrong sentences correctly, the software compiler shuts down immediately. Only if it is translated 100% correctly, you can continue to work with it. So you see, it is complex and therefore takes time.
In this release we have already migrated some code parts into WASM, but we will need another 4 weeks until everything is on a new basis. Besides that we will continue to work on the system logic, which is already coded in WASM, and integrate new functions into the EFB.
The future remains exciting!

Bug Fixes
The plane in question seems to have a broken slats and flaps indicator. As is typical for Embraer planes, the indicator should briefly show the flap setting as it moves through the different positions. In this case, however, the indicator shows the current position throughout the whole cycle, not just the position it is passing through. Adding that it’s fixed.
We have updated the Autobrake option in the EFB as the previous EICAS readout inaccurately displayed information related to the Autobrake setting. This has now been resolved by including a new section in the EFB.
Certain areas may appear to be cut off while moving from Off to Terrain to Weather modes when using the MFD in MAP View mode. This means that when using these different modes, specific areas of the map may be obscured. When you return to the Off mode, the cut-off region will be visible again. This has been corrected.
We are delighted to announce that we have made corrections to the APU startup process in aircraft simulations to provide a more realistic experience for pilots. Previously, the simulation did not accurately replicate the actual APU startup sequence, but with the correction, it has been resolved. These updates help us to improve pilots‘ understanding and preparation for the APU startup sequence during aircraft operations.
As we discovered a bug in the MFD vertical prediction, our pilots were receiving inaccurate and confusing information. However, we fixed the issue.
In real life, only turning on battery 1 is sufficient to access the MFD and EICAS screens. However, in the simulation, it was previously required to turn on both batteries. This issue has been fixed.
As we investigated the HYD ELEC PUMP 1, we identified an issue where the hydraulic pressure was significantly lower than the expected value of 3000psi, as it was only at around 50psi when the pump was turned on. Our team has fixed the issue.
The APU fuel pump transports fuel from fuel tanks to engines and the APU. When the APU is turned on, the fuel pump is replaced by the AC pump. When the APU and engines are both functioning, the DC pump continues to run, however only the ejector pumps should be operational. Just the ejector pumps should be engaged when the APU is turned off and the engines are running. This has been changed to reflect reality.
The Slat position gap in the 3/4-F configuration was previously inaccurate and did not reflect the aircraft’s actual performance. However, the issue has been fixed, and the Slat position gap now displays the correct values.
The issue of missing textures in path relative textures has been resolved. Our team has fixed the problem, ensuring that all textures are now properly displayed in their respective locations, improving the overall quality and appearance of the simulation.
When using metric weights set in EFB it initialized with LBS on ground page after reloading. This got corrected to initialize with the saved unit selection.
Improvements
The Flight Schedule page in EFB now logs the actual departure and arrival time (off/on-block).
The size of click points on the Electronic Flight Bag doors has been enhanced, which enables the doors to be opened and closed with greater ease and accuracy when handling and storing the EFB.
We added an “Operator” tab in the EFB settings page. All settings on this page will be stored per livery only. This also works with 3rd party liveries! Currently we only have the autobrake option in this tab, more to come in the future.
As we operate an aircraft in flight, we expect to see a white ‚SPDBRK‘ annunciation displayed on our EICAS, indicating that the speed brakes are retracted. We are glad to confirm that this is currently happening as intended.
As we operate an aircraft and execute a landing, we expect the EICAS to display a white boxed ‚GND SPLR‘ annunciation, confirming that one of the ground spoiler panels is extended and contributing to the aircraft’s deceleration. We are pleased to report that this is currently functioning correctly.
We are delighted to inform you that we have enhanced the HYD Pressure, Reservoir Quantity, and Temperature simulations in aircraft to provide a more realistic representation of the hydraulic system.
We have updated the Electrical Page Logic in the E175 to enhance the realism of the aircraft’s electrical system. This update provides pilots with improved functionality and performance, as well as more accurate and realistic information about the status and performance of the electrical system.
We have addressed an issue with the engine animation in idle power, which was previously unrealistic and did not meet our quality standards. Our team has fixed the animation to make it more accurate.
We have resolved the issue of excessive visibility of rivets on the aircraft livery, which was previously causing a distracting visual effect. Our team has made necessary adjustments to the livery, resulting in a more realistic and visually pleasing appearance.
Some logic is currently written in XML and tied to the manipulator calculation. This is inefficient because manipulators (animations) are calculated on a higher rate to provide a smooth visual result while the logic doesn’t require such a high rate. To reduce the calculation rate we need to migrate it into WASM. We already finished the electrical and APU logic in v0.9.4 and expect to be finished with all items in v0.9.5
In order to improve the performance, we need to migrate all PFD related code from JavaScript to WASM. The first part (converting HTML content into bitmaps) has been done in v0.9.4. We expect to finish this entire item in v0.9.5
