the burn PAD
« on: November 29, 2017, 02:06:27 PM »
How burns were actually performed in the Apollo missions?

In preparation for each burn, mission control would calculate the currently trajectory, and the magnitude and direction of the upcoming burn. Mission control then writes down the details of the required burn on a standard grid form called a pre-advisory data (PAD). 




Capcom then reads the values on the PAD to the crew, which then writes down its own copy. The crew then reads it back to mission control to check the values have been copied correctly. Ultimately, the crew punches the numbers on the PAD into the DSKY, which then performs the required burn.

The PAD includes information on when the burn should occur, the amount by which it should change the spacecraft's velocity, and the direction in which the spacecraft should be pointing at the time of the burn.

So far we have sufficed with a throttle lever for firing up the engine. For the Steam version we are stepping up the game to include also simulation of burns performed with PAD numbers.
