In the final phase of landing the AGC was running a program called P66 which was a semi-manual mode. The astronaut had direct control of the attitude of the LM but the throttle was calculated by the AGC to maintain a steady Rate of Descent (ROD). The astronaut controlled the ROD via a switch.
All the Apollo landings were done with P66, I think the AGC did have the capability to do a fully automatic landing but none of the crews wanted to try it.
- semessier 7y agoso was it planned then to use P65 (fully automatic) for Apollo 11? It's still not clear what the actual impact of the messed up command queue had - none, a few wrong thruster firings or getting the landing phase trajectory completely wrong?
- semessier 7y agoactually answering my own question in part, it's explained at https://www.hq.nasa.gov/alsj/nasa58040.pdf https://www.hq.nasa.gov/alsj/nasa58040.pdf pp. 21 ff. : P65 was apparently planned and there was a velocity error amongst others leading to a navigation error. What remains open is what material impact the interupt overload on the command queue had.
