This is a dynamically calculated suicide burn in just one instruction demonstrator.

You can play with the pitch in the ascent, it should work fine with horizontal speed. Feel free to try it on different crafts and share the results with me, I would like to have some help testing it to improve the instruction.

    i think its broken

    @crowxe that would be the precise approach, I wish we had a real AGL value though

    @pedro16797 then the most accurate way is put the landing stage on the pad with only the estimated fuel remaining on touch down and read the AGL . however if the fuel tank is CG is near the dry weight CG then it wouldn't matter. check my suicide landing burn, the landing legs kisses the ground before engine shutdown

    @crowxe it's in the CoM and the CoM changes after staging and burning fuel, so your grounded AGL will change during flight

    i do have a problem with AGL , i have to take the AGL reading when the rocket is on the ground as if the height sensor is in the command chip or CG

    @crowxe there is a problem with rocket agl when landed and that bounce is caused because I tried to make it hover and then land, but when it tries to hover if the tick speed is too low it bounces. If you slow time down that shouldn't happen

    i like the "piych 90 below 100 AGL" , it's genius, better than my " if lateral velocity < 5 " . the equation is too long for me to understand. in the test the rocket kinda took off again instead of touch down and repeated it couple of times. i use 2 equation lines. one to trigger the burn and one to control it. the control is just continuous calculation for the touch time based on vertical v in the light of mximum acceleratio minus the weight (M * G) , the result is gradual thrust to a hover befor touch down, now at that time if i subtract 1 or 2 meters from the AGL , touch down would just happen so so smooth.
