I can see density altitude having three effects:
So maybe each one of the above isn't enough to make a big difference in the ability to initiate a go-around, but together they do?
- Ground speed, for a given IAS will be higher. If the a/c is flying an approach at a fixed angle (as when using an ILS) as opposed to fixed vertical speed, that means v/s will be higher too.
- Engine thrust will be lower.
- I'd think the engines would spool more slowly in less dense air. That's just a guess on my part, but the turbo on my car spools considerably faster in cold weather than when it's hot...
