A doubt on cabin aircon

The FBOs in Phoenix have portable air chillers they roll up
to the airplane to cool the cabin and even the baggage and
battery compartment. But it can get hot inside withy the
engines at ground idle.


I was actually thinking commercial flights (as was, I thought, the OP...)

They can get cabins down right frigid when they get the hose in early and if
the compressor is running well...

I've actually heard people ask the FA if they could turn the air DOWN in
July.

Sorry for the blank post...hit the wrong key. What I was
going to say was that the FBO probably won't roll out the
air machine for your 172, but the bizjets and King Airs use
them all the time. An example, a heat soaked Beechjet
baggage compartment will reach the NiCad battery limiting
temperature and cooling the battery should be done before
engine start.

Interesting...

I've experienced what our desert heat can do to car batteries...it ain't
good.

The last time I asked, the battery in a Beechjet was over
$5,000. If I remember the limit, the maximum starting
temperature is 40 degrees C/104 F, which is a cool day in
the summer in Phoenix.

$5K??? Ouch...

(Note To Self: BeechJet ... No...)

104F ambient can translate into well above 120-130F in enclosed spaces.

I always felt bad for my CFI(s) who were not allowed to wear shorts...

All the aircraft NiCads are high dollar, but they can be
rebuilt since each cell is replaced as needed. Lots of user
have switched to lead acid batteries in the smaller King
Airs, but a $5K battery is small change when you're talking
over $2K to fill the tanks on each flight [dry tanks].

Shorts in flight are like shorts on a blonde on the back of
a motorcycle, looks good until the crash.
