To keep things brief, for a data exploration project, I calculated density altitude for a couple airports and used flight statistics from https://www.transtats.bts.gov/ONTIME/Departures.aspx.
I was under the assumption that a higher density altitude is bad for performance and would involve things like longer takeoff time which can prolong taxi out time(from gate to runway) since a plane in line would have to wait longer for earlier planes to takeoff. Is this true?
Or is there pretty much such a minuscule difference that density altitude shouldn't matter in the context of taxi out time?
