COrrective steering tries to fix this, as it should, by pitching down below prograde. However, late in the flight, it sometimes ends up pointing *below the horizon* - negative pitch values - in an attempt to get me back on the ideal course. This is obviously inefficient - I *want* to go up, and burning down is counterproductive. I'd like an option that will prohibit corrective steering from going below the horizon.\r\n* Smooth Throttle during coast to apoapsis: When coasting to apoapsis, the occasional burst of thrust is needed to counteract drag and keep the apoapsis at the target value. Currently, MechJeb does this by slamming instantly to full throttle for brief instants. It would be nice if it instead gently ramped up the throttle, to avoid unnecessary jerking.\r\n* Early Circularization Burn When Necessary: Sometimes, with low target orbits and low TWR upper stages, MechJeb will achieve the target apoapsis, coast for a minute or two until we exit the atmosphere, and then plot the circularization burn only to find out that it should have started burning two minutes ago. It would be nice if it checked for this, and started the circularization burn early when necessary."},"comment":{"url":"https://api.github.com/repos/MuMech/MechJeb2/issues/comments/109555488","html_url":"https://github.com/MuMech/MechJeb2/issues/612#issuecomment-109555488","issue_url":"https://api.github.com/repos/MuMech/MechJeb2/issues/612","id":109555488,"user":{"login":"sarbian","id":4083375,"avatar_url":"https://avatars.githubusercontent.com/u/4083375?v=3","gravatar_id":"","url":"https://api.github.com/users/sarbian","html_url":"https://github.com/sarbian","followers_url":"https://api.github.com/users/sarbian/followers","following_url":"https://api.github.com/users/sarbian/following{/other_user}","gists_url":"https://api.github.com/users/sarbian/gists{/gist_id}","starred_url":"https://api.github.com/users/sarbian/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sarbian/subscriptions","organizations_url":"https://api.github.com/users/sarbian/orgs","repos_url":"https://api.github.com/users/sarbian/repos","events_url":"https://api.github.com/users/sarbian/events{/privacy}","received_events_url":"https://api.github.com/users/sarbian/received_events","type":"User","site_admin":false},"created_at":"2015-06-06T09:25:02Z","updated_at":"2015-06-06T09:25:02Z","body":"Current Acceleration report the engine stats only, drag & gravity are not accounted for.
