Hi devs I'm encountering an odd behavior with PX1.14 (SDK 1.0). Indoor flight with VIO. GPS antenna not attached. PX4 is configured to transit to Land when a link loss (not RTL) is encountered. Takeoff the aircraft and move horizontally somewhere away from the takeoff point. Close QGC application to simulate loss of link. The aircraft goes into Land mode - but while the aircraft is descending, it translates in the direction of the takeoff point as well until it touches the ground. Verified this by simulating loss of link at various positions relative to the takeoff point and it always translates in the direction of the takeoff location. I'm certain that this behavior wasn't present in 0.9.5. Failsafe Landing ought to be completely vertical. Anyone with any idea what is happening?

After further testing, i can confirm that this behavior does not occur to failsafe landing only but normal Landing mode as well (ie. operator select flight mode).

@Eric-Katzfey Has any testing been done with this fix in GPS mode?

@swickliff No, it hasn't. Supposedly all of this is fixed in latest mainline but we haven't tested it. But we do have a mainline build available to try: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mainline-px4_1.16.0-1.0.0-202502271326_arm64.deb
