Without commentary it was hard to figure out which aspects you were testing on each landing. Couple of hours! The tests were completely automated I was sleeping at the time, since they were running from about 3 till 9 AM. The test is simple: pick random surface target and land. Log the success/failure along with the final error and fuel used. I was checking if my fixes are working for wider set of situations than the one I used for manual testing. 4 hours ago, Daveroski said: Does TCA play nice with the 'other' one? The only reason I'm asking is that The 'other' one does help with interplanetary nodes. Yes, I used TCA with MJ maneuver planner many times. You obviously shouldn't use both at the same time to control ship's attitude, engines and such (e.g. to execute a maneuver node). But enabled and idle TCA won't interfere.

SkiRich 15 Posted July 29, 2020 Share Posted July 29, 2020 @allista Can you point me to a video tutorial (or any tutorial) for hot to setup a rocket to use TAC as an autopilot to precisely land at a base? Quote Link to post Share on other sites

This is old, but it shows the process of landing from orbit. Starting from 11:12 There's not much setup, except that you need deorbit autopilot module and it's dependencies installed in TCA GUI in Editor. It would work for a simple rocket with some axial engine, if it has enough torque in reaction wheels and RCS. Quote Link to post Share on other sites

Dejakr 2 Posted August 1, 2020 Share Posted August 1, 2020 (edited) Great mod, have used this in the past with great success. Thank you for the good times. When I tried to use it today, however, it doesn't seem to work. I'm able to group my engines for my aircraft in the builder and do all the other setup, but when I get to the runway I have no UI and no button will summon it. My plane immediately faceplants as if there is no balancing going on, either. Please help! Edit 1: I started a new sandbox game and it works there. It may be that my science playthrough has an engine or cockpit type from an incompatible mod. In the broken save, the engines allow grouping and the cockpit says TCA software is installed so I don't know why it doesn't work. The engines are "Deployable" types for changing direction of thrust, could that be an issue? Edit 2: TCA mod works on the first plane i will link to here: https://ibb.co/ByXGSWK But TCA refuses to activate on this other plane and I can't fathom why: https://ibb.co/RjY6gFH Edited August 1, 2020 by Dejakr update 2 Quote Link to post Share on other sites
Dejakr 2 Posted August 1, 2020 Share Posted August 1, 2020 OK I figured out the conflict in my earlier post (not able to edit it, my account is too new and it's under review) Apparently a landing gear added by a mod was causing TCA to not operate. Insanity Aerospace, I think it came from a mk2 parts expansion mod. Quote Link to post Share on other sites

It's just too inconvenient to have to use two autopilot systems at once. Then again, I don't know how MJ looks now, but as I remember it, it was quite different from TCA in approach.

Daveroski 516 Posted August 7, 2020 Share Posted August 7, 2020 When launching from KSC to intercept a target in orbit, I need to lower the angle of attack so that drag doesn't kill my ship. Can I do this? D. Quote Link to post Share on other sites

The drag is arising from the fact that while the air is travelling in a retrograde direction the ship is not taking advantage of it's needle like shape and instead is trying to fly several degrees off prograde. Those several degrees present a long surface area to the wind and cause a tremendous amount of shear. My light but powerful ship becomes 'a leaf on the breeze' but not in the way that was meant in the popular show. If I can cut down on that shear, my awl like vessel will respond just as well using your autopilot as it does by my hand and I just paid your autopilot a compliment because I fly beautifully. D.

Ah, I see. So what we actually need is either an option to set maximum deviation from prograde (currently it is hard-coded to 10°), or an option to offset the start of the gravity turn to lower dynamic pressure. Or maybe I could just made the former dependant on the latter. Could you, please, share the craft file, or, better, make something pure-stock that'll have the same problem?

Well now... there's the rub right there see? Most of my ships don't like the 5° that MJ defaults at I almost always have to drop it a couple or three. If yours is hard coded at 10° then that will explain the nose getting pushed down by shear. The bigger and heavier the craft, the less the affect. As bigger craft tend to be Bum Heavy, I like to make a craft just big enough to do the job. If I have to drop more than my emergency reserve of fuel before re-entry, I get sad. < sad see? I always try to make a craft that doesn't need tail fins and most of the time I manage. But even with tail fins and a heavier craft that 10° shear is like taking an uppercut... pow! right on the noggin. I don't only want to be able to change that variable. I want your Auto Pilot to take the variable into account and not be too late to catch the bus after I have changed it. Now I am playing with a bunch of 0.625 While I am not that bothered about a launchpad for it, I have managed a rescue from lunar orbit and I suspect I can do a rescue from the surface of The Mun using the same wee system. It is all terribly unrealistic but it is a LOT of fun. Anyway... these little rockets really hate your wind shear. But as I said, I even turn down MJ to 2 or 3° even for most of my own stock rockets. 10° is just way too much. D. Quote Link to post Share on other sites

I really noticed the problem when I was playing with But had the devil of a time trying to reproduce it on stock craft because most of the vanilla parts are a bit bigger. So I found this old bird in one of my archives and brought it back from limbo. Now here's the thing... I can fly it to orbit manually easily. Once one understands that these thrusters don't want to be at low altitudes then the idea is a steeper ascent to let them work where they work best. MechJeb can fly it to orbit if I set it's AoA to 2 deg. It still has to have the cowl jettisoned too soon and it has a bit of a psychotic twitch trying to keep the Ap at 100m but it manages. To give MJ it's due, it had almost as much fuel left in the last little tank as I did. Your auto pilot can get it to around 23000 meters I have tried having the 'Time to AP' manual longer and shorter. but it just ain't workin'. It is fighting the atmosphere all the way. Trying to get into a fast horizontal configuration so that it can get the Pe down at the same time. (Which MechJeb managed to do by-the-way got it up in the 40k's) As requested, Craft file and metadata file. https://www.dropbox.com/preview/KSP stuff/Little Squawk.loadmeta?role=personal https://www.dropbox.com/preview/KSP stuff/Little Squawk.craft?role=personal https://imgur.com/NYkgO31 Ain't she purdy?.
