REFLECTOR: Cabin Heating

[Chuck Jensen]

John,

Could be.  Do you smell it for a while, or just briefly?  I smell mine for
4-5 seconds, then it's gone.  The briefness of the odor probably also says
something about the amount of air that transverses the nose area, thru the
keel and into cabin, that the smell comes and goes so quickly.  Granted the
underside of the wing/wheel wells might be a high pressure area at high AOA,
but the nose gear area is always a hi-pressure area. I would think that the
inflow to the cabin from the nose area would "flush" the air thru the cabin
and out the gear leg opening in the fuselage and not allow air from the
mains to back up into the cabin.  

Next time I fly, I'll tell the significant other go get behind the back
seats with a candle to see which way the wind blows when I take off.  That
idea will probably heat things up and  cause a stink but it won't be from
brakes or tires.

Chuck

Chuck,
I have no rub marks on the nose doors, but do have some on the insides 
of the fork so I suppose it's possible.  However when I landed I sniffed 
all around and found the identical smell at the brakes and nowhere 
else.  I do expect my brakes to be hot on takeoff because I'm still 
wrestling with my technique for steering the nose wheel.  I also expect 
under the wing to be a high pressure area during high AOA which would 
force air into the cabin.
