ProjectApolloMFD

Screenshot of the ECS screen.

There are "information flows" between the ground and the spacecraft, which cannot be handled by the panel displays and controls alone. Trivial example is mission time during prelaunch. Neither the mission timer nor the AGC can display a launch countdown. In reality it would be quite useless, just in case the astronauts forgot liftoff time they can ask mission control whenever they want to. So Project Apollo has it's own MFD to address this issues. To use the Project Apollo MFD go to the "Modules" tab of Orbiter's launchpad and activate the ProjectApolloMFD module.

The MFD displays the current mission time always on top of the screen, all other informations are available on the various screens, which are selectable from the main screen.

IU TLI burn program

• Calculate time to ejection and delta velocity as usual and as you do for the Simple AGC P15 program.

• Select Project Apollo MFD as MFD.

• Press TLI.

• Press V and enter delta velocity in m/s.

• Press T and enter "1200" for 1200s for instance.

• Wait until time to ejection is exactly 1200s and press RUN, the status changes to WAITING, you can stop the burn by pressing STP.

• At 900s before time to ejection the burn data are passed to the IU, status changes to RUNNING, you can't stop the burn with the MFD but you can inhibit the TLI burn sequence by switching the XLUNAR INJECT switch to SAFE until 18s before SIVB ignition, after that you can do this by using the S-II/S-IVB LV STAGE switch (permanent inhibit when used 12s after SIVB ignition or later) as ususal. Now the time to burn is displayed counting down.

• The IU performs the burn as usual, after that's the status in the MFD changes to OFF, press BCK to disable the IU TLI burn program.

• If something goes wrong (if you try to do a TLI burn while sitting on the launch pad for instance) the status changes to ERROR, press STP and try again...
