Reentry - A Space Flight Simulator News

The 0.99.13 will mainly focus on the Apollo Command Module. It will correct issues reported by the community and improve existing systems. It will also improve the fuel cell purge, attitude ball drives, GDC align and HGA antenna deployment.

Note: If you are experiencing issues with this build you can roll back to the previous using the Steam Betas Tab accessible from the Steam client (games properties).

FDAI Attitude Ball improvements
I have improved the logic behind the attitude indicators (FDAI). Logic will now drive the attitude balls to the internal attitudes instead of snapping when for example performing a REFSMMAT, aligning the platform and during GDC Align.

This requires you to press and hold the GDC ALIGN button during pre-launch procedures and alignment procedures. I have updated the Academy and the checklists to include this.


Fuel Cell Purge logic
The Fuel Cell Purge logic has been improved to better reflect the real procedures - and will add up to the things you need to do during coasting. The Fuel Cell flow indicators will reflect the purge as O2/H2 flows through the system. I have also mapped the Caution and Warning System logic so that a Master Alarm will trigger due to the increased flow.



Checklists related to these procedures has been updated.



SM RCS Fuel Quantity Sensor
I have improved and fixed issues related to the SM RCS Fuel Quantity sensors used to show how much fuel you have in the various SM RCS fuel quads.


Apollo Save State improvements
I have added some new data to the Apollo Save State. The SPS Helium quantity, SPS N2 quantity, O2 and H2 quantities, and Battery A,B,C and Pyro Bat A, B charges are now stored. I have also added the triggered Failures to the save state.

HGA deployment
The High Gain Antenna logic and model has been updated. The antenna will now spring out during SIVB/SLA separation. The rotation joints has been update so both pitch and yaw is mapped correctly with the model joints.


Attitude Set Control Panel (phase 1)
I have started to work on the logic behind the Attitude Set Control Panel to better reflect real procedures. The switches related to the platform and GDC align has also been reimplemented. You should now be able to follow more realistic procedures when performing a GDC Align such as aligning the GDC with the IMU inertial platform.

The simplified logic still exists and is the recommended approach. If you set the ATT SET switch on MDC-1 to IMU and press in GDC ALIGN, the GDC platform will automatically be set to exactly match the IMU platform.

If you set the ATT SET switch to GDC, you will need to use the procedures to set the attitude using the ASCP, then press and hold the GDC ALIGN button while the new logic will drive the attitude towards the desired alignment attitude set on the ASCP.


N20 has also been update to map the angels better


Note: This logic still have some issues when the attitude is far or facing Euler challenges, so if you execute this procedure and the logic is unable to align and drive the platform correctly, use the simplified approach, or maneuver the command module closer to null the error needles in ATT SET->GDC mode.

Checklists related to these procedures has been updated.

SPS Pc gauge
I have fixed a bug that would freeze the SPS Pc gauge at 45. The gauge should now show the SPS thrust while performing an SPS burn.

Patch Notes:

• Updates to the FC1,2,3 purge logic
  
• Fixed the SPS Pc gauge to monitor SPS thrust
  
• Fixed the SM fuel qty sensor -> gauge on the MDC-2
  
• Corrected a typo in the SPS Deorbit (Earth Entry) checklist
  
• Apollo Save State improvements
  
• Attitude ball drives
  
• ASCP improvements
  
• HGA deployment
  
• HGA pitch/yaw control joint updates
  
• Backspace will null rates in Mercury and Gemini
  

This update will correct multiple issues reported by the community.

Lunar Ascent fluctuations
During the Lunar Ascent, the CSM orbit fluctuates as the Lunar Module burns its APS engine. This update makes this stable.


Optics Panel
For some reason the Optics panel textures had reverted itself to the CM Block I configuration. I remade the textures and updated the logic so it correctly represents the CM Block II configuration.


LM Batteries
After the previous update, the LM batteries all had low voltage. This has been corrected but more work is needed in the LM circuit logic.



0.99.12 patch notes:

• MNB undervolt while connected to GSE/ground umbilical due to recent EPS changes corrected
  
• Gemini O2 High Rate switch corrections
  
• Fixed the Optics panels that had, for some reason, reverted the textures to Block 1 (thanks for reporting GoForPDI)
  
• Modifications to TLI (concatenated) checklist
  
• Published the CSM charge battery procedures
  
• Corrections to the LM battery circuit & voltage logic
  
• Lunar Ascent fluctuations on the CSM
  
• Corrections to Mercury Cabin H2O Warning light
  

This minor patch will continue to improve the logic related to how the voltage of the CSM batteries are rendered. This will take into account the amps load on the battery as well as the depletion of the battery when you monitor them using the DC VOLTs gauge on MDC-3.

It will also fix the runnable steps of the Battery Charging procedure. In the video I made yesterday, I opened both of the Battery Relay Bus circuit breakers when I demonstrated the procedures. Do not open both of these as it will shut down the entire Battery Relay Bus - making it impossible to make critical changes to for example the FC radiators, inverters etc. - the battery relay bus powers these.

Thanks to Folgers, Amaryllis, CaptainSwag101 for helping me with the details!

The following patch will correct bugs/issues reported by the community and add more realism and tasks during coasting. This new feature will improve the way you charge the Apollo Command Module batteries, both the logic and the procedures. This is a procedure referenced in the various Apollo Flight Plans and usually had a schedule (battery charging schedule).

Note: If you are experiencing issues with this build you can roll back to the previous using the Steam Betas Tab accessible from the Steam client (games properties).



The update will also change the seat you sit in when you enter the Lunar Rover Vehicle, and correct the radial menu used during Lunar EVAs and while riding the LRV (this broke with the previous patch).



This patch will also fixes the issue where you were unable to draw on the in-game Gemini PAD-forms.

Improved CM Battery Charging logic and procedures
It has been possible to charge the batteries in the Command Module, but no proper output was shown to you. This update changes this to follow the real procedures use to charge the batteries.

This video will cover the procedures and details around charging the batteries:

The following schedule shows the charging of Battery A and B during a real Apollo mission:


Thanks for everyone for reporting issues.

Change log:

• Fixed the radial menu during Lunar EVAs
  
• Corrected so the player sits on the drivers side of the LRV
  
• Prevented external view modes during VR
  
• Prevented opening the Gemini Mission Tools if in VR
  
• Updated the procedures for charging the CSM batteries
  
• Improved the battery charging logic/implementation and instrumentation
  
• Fixed an issue where the Gemini PAD pen did not work
  
• Added more system tests to panel CM panel 101
  

This is a minor patch that corrects and improves the anti-aliasing (visible artifacts/bleeding) during normal play, and the laser pointers while in VR mode. This will make interaction easier as the pointers will now better and more correctly target the object it points at, cut the ray and render a small cursor at the collision point.

The patch will also fix an issue with the anti-aliasing located in the post-processing layer of the game. This issue rendered a glare on one of the eyes in VR, and caused bleeding artifacts during flat mode rendering (non-VR).

This layer is combined with the general anti-aliasing setting accessible through the Quality settings from the Main Manu.

Post processing can be toggled completely from the same menu. For VR play, I recommend turning off all post-processing layers and antialiasing for performance reasons if you struggling with low framerates.

Patch notes:
- Improved the VR laser pointer and ray casting logic
- Fixed anti aliasing issues
