Density Altitude to the Max
I'm headed to Truckee, CA tomorrow and the forecast high temperature is 102F/39C. Since Truckee is at 5901MSL, the density altitude is effectively infinite.
So how will I handle it?
First, I had originally planned a fuel stop, but the DUATS flight planner using the route I actually intend to fly (rather than some impossible shortcut: see here) shows me arriving with a little over one hour's fuel remaining. Less weight is a big help in this kind of situation, reducing stall speed and landing distance, so I don't want to have much more fuel than that.
Second, I will keep an accurate navigation log, and if things are not going as expected I will make the fuel stop anyway, but I won't fill the tanks. It should be a little less than 2 hours from truck to Truckee, so I'll depart with 3 hours of fuel.
Playing with a Koch chart shows that my expected landing and takeoff distances are about 260% of normal. Truckee's longest runway is 7,000' long, more than 4 times my normal landing distance. With the high density altitude, though, touchdown true airspeed will be pretty high, so I'll need to brake carefully. Again, less weight means less energy means less braking.
Checking the TAFs shows 8 - 15 knots of headwind on arrival; that's a big help, too.
Truckee is very noise sensitive and there is lots of glider activity; the airport publishes arrival and departure routes to help reduce the noise and keep the powered airplanes (in this case, me) separated from the gliders (someday, me). I have downloaded the guide and put it into my tablet device using Dropbox.
I would like to depart for home with full fuel, but with density altitude this extreme I might decide to depart with less and stop someplace lower for more. "Lower" is a loaded term, because fuel is relatively inexpensive at Truckee, so lower might be higher when it comes to money. But safety trumps money.
The only remaining question I have, then, is what will the heat do to the fishing?
