It would be good if there was a dedicated \"takeoff\" flight mode that didn't need mission planning to use. One like the MFD autopilot has. My plane is well tuned and can run fully automatic missions takeoff to landing when planned but a launch mode that just had to be set like any other flight mode would be great. One that continues in the same direction you throw the plane. At the moment I have a switch to ramp up to takeoff throttle add elevator and put the plane in stabilise which works but not as well as auto takeoff in auto mode.

I've never seen a jump\ngreater then 3 meters (this is with airframes in the 5 to 3.6kg range). I\nagree though that anything below 60 meters feels low at this size.\nOn Sep 7, 2015 10:18 PM, \"Severin Leuenberger\" <notifications@github.com>\nwrote:\n\n> my comment why 20m above ground;\n> I fly APM 2.6, 3.1 and pixhawk fixedwing drones in sizes from 500g to 9kg.\n> I recognized jumps up to 10m on baro due to turbulences or what ever it was\n> (not calm weather). So it would be a bad thing, if the \"done_takeoff\" =\n> true would be reached due to barometric pressure sensor disturbances.\n> Therefore I reccomend 20m or even 30m.\n>\n> Second thing is; for a fixed wing - 20 to 30m above ground after takeoff\n> is not a lot of space between aircraft and ground (unlike copter). I would\n> say 20m is the minimum height who as to be climbed to be in a safe distance\n> above ground. For me 30m would even fit perfect, but for small planes < 1m\n> wingspan, this could be to high.\n>\n> —\n> Reply to this email directly or view it on GitHub\n> <https://github.com/diydrones/ardupilot/issues/2811#issuecomment-138436669>\n> .\n>\n"}}
