Hello,

Since BFS has now its own set of CWS warning messages (most of them coincide with PASS, but there's some that are specific to either system, so I had to separate them) removing the blinking last message from BFS now requires depressing key on the keypad talking to BFS


Was it introduced in the last dev version from january ?

Just a quick post to show the effect of thrust and consumption adjustments on propellant remaining and payload limitation.

Here, a 40k lbs payload with an OMS assist of 4000 lbs ( 100 seconds) for a direct insertion on a 51.6 ° Orbit
( Max payload for that INC in SCOM performance)

Just 2000 ish lbs prop remaining , quite alike real Final Performance reserve.
Just enough to not let the engines dry out and damage the Turbo Pump :)
Tested RTLS, TAL and ATO also. At FCOM Limitations .

I will do a thorough report later.

Same test with a due East Launch, and 50 k lbs payload ( we might go up to 53 kish lbs for a 120 Nm Apogee)
13k lbs more than for the same Launch towards ISS, that is becoming challenging payload wise :)

On the limit, less than a percent remaining
