Freezing passengers

[podair]

Now winter is approaching the back seat passengers on my M20F are complaining they are freezing, severely limiting their enthusiasm for high altitude flight....

The cabin heater is blasting hot air like a furnace up front, so I am perfectly happy at 10k ft in a Tshirt with -20 outside.

However my family at the back is wearing jackets and scarves and wrapped in an electric fleece and freezing!

It seems it is all coming from the baggage bay.

Has anyone found a convenient way to redirect some of the heat from the heater vent on the pedestal to the back seats, like some kind of removable duct or hose?

I have also thought of maybe sealing the baggage area with a fleece or padded curtain, with velcros attaching it to the roof of the cabin.

I have replaced the door seals and it has made some difference already.

Any suggestions welcome !

Check the scat tubing going to the back seats. Also there is a small duct running into the baggage compartment. Make sure it is connected as well.

Otherwise, try putting a blanket in the back of the luggage compartment. When I redid the interior of my plane, I added insulation to the aft section of the plane for that reason. It did reduce the complaints. I usually try to duct as much heat to the back as I can. The front seems to be well heated.

I prefer my pax fresh not frozen but when they are frozen you get fewer complaints. :-))

I gues you could set up some type of temparoary scat hose from the front to the rear. Just make sure it is not obstruction any controls.

3 new scat hoses one to each seat. Front passenger gets the air box in front of them.

Check the movement of the air valves controlling the air flow. Two on the firewall, engine side and one air box on the passenger side.

Close the air entering the cabin, roof vents, door seals, instrument panel cooling.

Then a big blanket that captures the hot air from the front air box all the way back to the back seats.

If you close all vents, than consider having a CO gauge or some device to keep from accidentally creating a new problem.

Good luck.

You will notice two small vents on the side of the fusaladge that vent into the baggage compartment. You may want to block them in the winter.

You may want to remove the side panels and rear seats and check the seam between the floor and lower wing skin. This is a 2-3 inch wide gap that was taped up at the factory. The tape had long since turned loose and was just laying there. It took two afternoons to remove the old stuff, clean up the mess and retape and seal it. I found some heavy weight aluminum tape with fiber reinforcement from mcmaster and 3M caulk strip. If the plane has ever had fuel leaks around the root of the wing, the tape adhesive will be disolved by the fuel.
