Apollo 7 P27 update

[MrFickles]

Around 121.5h GET, there is a P27 update in the flight plan. It's a P27 state vector update sent up from MCC via voice.

What is the purpose of this P27? Am I supposed to enter it into CMC manually or is it just for reference for the upcoming sequence of P22s?

I think that state vector is a backup, in case you screw up your state vector in the computer during the P22s and are currently out of range of a ground station to uplink you a new one. You can enter it between the P22s as a test if you want, probably doesn't hurt.

Thanks indy, I'd figured it's in case something went really wrong with the P22 sightings. I just manually did a P27 anyway even though the P22s went really well.


I'm flying through the Apollo missions again starting with 7.

Apollo 7 has just splashed down. Getting ready for 10 laps around the moon.
