That is correct although it has an internal tray that holds the ice up out

of the melt water. You can then select 'icy breeze', 'water mister', or just

fan only. The ice doesn't last long depending on how cold the ice was to

begin with but it only needs to last until OAT drops. It's small enough to

fit between the seats and as PIC I require that the 'icy breeze' be directed

towards me. I haven't weighed it with a full ice load but I think by the

feel it's going to be well under 18lbs. After the ice melts you could drink

the melt water and then the weight wouldn't count, would it?

It all goes back to the question:   It's not how many horsepower you 

have, not how many gallons your wingtip tanks will hold - it's how big 

's your bladder........

Al,



"The ice doesn't last long depending on how cold the ice was to

begin with"  



Wouldn't the ice be something like 32 degrees all the time?

I agree....Not much more than two hours for me....



Good luck on your inspection.

I can't believe that I'm the only one who has the whole family use the

little john and lady-j adapter and fills jugs up on the flight.

We routinely fly 4+ hour non-stops.  I find that it can be anywhere

from 1 to 3 hours before the first person pipes up and wants their

turn.  I usually try to make sure that my head and bladder are clear

before an approach, too....so there's only one thing on my mind

and that's getting the plane down smoothly.  Yeah, I know there

are many who won't want to do that task in the plane, but I just

can't picture going without....I'd need to have Abby sew up some

"Depends Dispensers" for us otherwise.  Ain't no way I'm going

9-10 hrs x/c with stops every 1.5 hrs.

You're not alone Tim.  Little John and gel pacs do the trick here.

I learned the hard way in glider racing that trying to manage your 

hydration for endurance, costs too much in  performance.  External male 

catheters were the trick there.

..and be careful trying to jettison liquid waste without careful 

engineering and fore thought. $$$$

I was thinking of a trailing 1/4" tygon tube, coming out of the area of

the rear tiedown ring...extending back 3' past the rudder.  I could

even make contrails (more like ice pellets) on the winter flights. 



Or maybe redesign my cats whiskers Nav antennas to be hollow tubing.

That would be a great mod!

No need for off loading there is a perfectly good ice chest sitting

between the two of you. Just don't confuse it with lemon aid...

I slept in a Holiday Inn within the past year so feel competent to answer

this question. Ice can get cold as h... but not warmer than 32. So if you

stoke the ice chest with ice out of the freezer (around 10 degrees I think

for home units) as opposed to ice that's just getting ready to turn into

water you get more cooling. I keep a bag in the freezer side of my fridge at

the hangar just for this-and no other-purpose.

Zero ice weight for dry ice...... 



 I haven't weighed it with a full ice load but I think by the

feel it's going to be well under 18lbs. After the ice melts you could drink

the melt water and then the weight wouldn't count, would it?

Well Albert, you got me to thinking - it is true that chilling your ice below 0 C will give you a little more cooling, but just a little more, because it takes to much more heat to melt a given quantity of ice than it does to merely raise the temperature. The specific heat of ice is about 0.5 cal/g, the latent heat of fusion is 80 cal/g. So, if you cool your ice in the freezer to -20 C (which is a very cold household freezer), it requires just 10 cal to warm each gram of ice to the melting point, but another 80 cal to actually melt it. So, in round figures, you gain only about 10% by chilling the ice. The things I find interesting......

Well, I only actually spent one night in a Holiday Inn...

I was thinking of dry ice but it is kind of expensive.

Albert

PS: flew up to Sedona Sat. for their plane and car show and the spring bias

rudder trim system worked very well. If I climb a little aggressively on

take off I do have to add a little right rudder but otherwise the trim

system handles climb, cruise, and descent.

Hey Albert,



Sometimes I can't tell yet when you guys are spoofing, but just in case I'll pass this along.  Just this last week I heard of two guys that died because they kept dry ice in their tent and the CO2 got them.  Probably lots of ventilation in the plane, CO2 sensors, etc. but I don't think I'd use dry ice.



Later, - Lew

I think I know the problem,,, wasn't it a Holiday Inn Express that you needed to stay in!
