There's two reasons not to go to full rich for landing. For me the most
important is density altitude. I live at 3650 msl and see lots of flatlanders land full rich on a 90 degree day and have the engine quit on rollout. Running full rich in these situations is just ****ing power away when you need it. The second reason is fouling the plugs.

I can tell you from experience with injected 360-520-540-720, that many a hot engine will quit if used like that... Personally, I leave the engine partially leaned in the landing pattern... I can see it both ways. In the UK, the SOP is to go max-rpm and full-rich on short final, in anticipation of a go-around. That's SOP in the US, too. I've never heard of what Denny and Newps are suggesting, but then I don't fly a big-bore, and don't keep up with their SOPs. |

I'm logged in via another route, but it's not smart enough to know that when I follow this link.
