I'm in the left downwind at my favorite non-towered airport. Just while I'm making the turn to base, I hear a radio call on CTAF: "Such-and-such Traffic, Medevac 123, holding short runway 31." They don't make any requests or say anything else; they merely announce that they're there, waiting for me to land and get clear.
Since they're a medevac flight, should I abort my approach and let them take off immediately, or is it fine if I simply land and vacate the runway as soon as practical?
If I abort the approach, what's the best way to do that, given that I'm on the base leg now? Continue past the runway and make an upwind leg? Just turn right and exit the pattern completely, and then come back once the medevac flight is out of the way?
And whatever the right thing to do is, what radio call should I make? I assume that there's something more standard than "Medevac 123, Diamond 456, I'm just gonna continue past the runway and make an upwind leg so that you can take off right away."
(This happened in a 2-seater I was riding in today. In this case, the pilot decided to simply land and get clear of the runway quickly.)
