Bug report - Minor - KSP 1.3.0 x64, latest KER from CKAN:

"Impact Time" in seconds appears to be off by a factor of 10 when parachuting.

I think it is more the fact that KER shows the "time to impact on current orbit" here and disregards deceleration from atmospheric drag and parachutes.

Is there a way to keep Kerbal Engineer (for building) but to remove the flight engineer icon + disable flight engineer? 

Two ways:

1. Change the settings to require the part to enable KER, place the part on the craft when building and remove it before flight.

2. Don't click the icon in flight. :P

Probably. Maybe it would be better to recolor the font or switch to a different prediction model when in atmo?

pardon my noobness but is there a way to get an older version for 1.2.2?

if you go to the CurseForge repo linked in the first post and then click the "Files" tab, it will give you all the old versions of KER and tell you what version of KSP they are for

I have a suggestion... I haven't found any other mod that does this, and it seems like it'd fit in very well with how KER works.. and maybe it already does this and I can't find it?

anyway:  please let me see *actual numbers* for distance fore/aft and laterally, of the center of mass/center of lift/center of thrust.  Those ball things that stock has are ok, but I want to calculate things and compare between craft, I want to see *actual numbers*.  Would this be possible?

You could check out RCS bulls aid. That has an engine display that shows rotation from torque forces and which direction. Not the numbers you're requesting, but might serve the ultimate goal.

Already have that installed, and no it doesn't unfortunately.  I need to see how much, quantitatively, adding and removing certain parts shifts the center of mass...

Could be worth submitting as a feature request for that mod too. Double the chances it'll get done.

I have a minor issue with KER and I'm wondering if anyone knows of a fix:  I have a interplanetary mothership which relies on crossfeed through docking ports to reach over 10,000 m/s delta-V.   The problem is that KER is not displacing the correct delta-V in-flight.  Here is a picture of said vehicle:

The NERV engines are set to drink from the outermost Mk3 tanks first, then the inner Mk3 tanks and finally the Lf in the central stack.  I will undock each set of tanks as they are emptied.   The outermost tanks provide over 2000m/s of dV but KER is giving my current stage dV of 0.  The overall vehicle has something like 10,000 m/s dV.   It seems that what's tripping KER up is that the decouplers aren't staged so it has no way of knowing the total vehicle dV.  However, I don't understand why it's not giving me the correct numbers for the current stage.

How can KER possibly know how you're staging this? You have to activate staging on the decouplers and put them in the staging diagram so KER can analyse the vessel as it empties.

I get why KER won't show me the dV for the whole vessel.  I'm mostly confused about why current stage says 0 instead of ~2000.  The NERV engines have access to over 20,000 units of LF.

Is the thing about showing actual numbers for CoM/CoL/CoT/etc difficult?  is there a hook in the code for that and it simply hasn't been done, or is this something that's actively being hidden from the API?  ... or am I the only one that wants this? lol...

I never got my head around this - TWR in VAB with KER set to Minmus is somewhere around 3.3 - but in orbit around Kerbin it has measly 0.02 ... ?

The thrust-to-weight ratio of a rocket, or rocket-propelled vehicle, is an indicator of its acceleration expressed in multiples of gravitational acceleration g. Minmus has lower gravity then Kerbin, therefore a ship will have bigger TWR around Minmus, because it's value is expressed in multiples of gravitational acceleration of a local body..

In your pic the currently active stage has no active engines in it, so...
