For those of you that are flying or for those of you that have spent 

some time in one of the transition aircraft. How would you assess the 

need/desirability of overhead fresh-air vents? I've read comments that 

the standard Van's vents provide an abundance of air, however most of it 

is aimed to low (gonad refrigerant). If the Naca Vents were ducted to 

provide fresh air to the pilot/copilot face/head/trunk from a little 

higher on the instrument panel,would the overhead vents still be worth 

having ?  I've got the Cabin cover off and now would be the right time 

to add something if it's necessary, If it's not that's one modification 

I'd be happy to forgo.

Howdy Deems,



Personally, I still think the vents are one of the biggest design flaws

keeping it from being perfect.  Even if you put the vents up higher

on the panel, you may want to redesign things a little.  I've now found

when flying in rain that indeed the rain does come in the vents, and

if you close them, a puddle will form and it will bubble water into

the plane.  So at minimum, some drains might be a good idea, that drain

to tubes out the floor.   But even then you'd be stuck with keeping the

vents closed in the rain.  So to me, overhead vents would be a great

thing to have.  I used to use my overhead vents nearly year round

in my old plane...I just liked a little fresh air on my face.  But

when you're limited to only the 2 big vents up front, it's just

not as easy to make things comfortable.  Once some people get flying

with overhead consoles and everything is plug-n-play, I may actually

add one to mine.

In my opinion, the stock vents are quite adequate for cooling. You can  point them up toward your face if you need it, or elsewhere if you don't want  all that wind blowing on your microphone. For a while I had diverted the  passenger vent for avionics cooling... I was able to keep the most finicky  passengers happy in 100 deg weather by directing the pilot's vent cross  cockpit.

  

 Personally, I would not spend the effort or panel space raising the stock  vents higher or installing overhead vents.

I second Jim's Opinion, but like Tim Olson, I may add an  overhead console and overhead vents when I install my flightline interior (less  seats), due for delivery in January.  My wife installed a headliner but  decided after Grady O'Neal at GLO Custom Paint did such a wonderful job on  the paint that she wanted me to order the Flightline interior.

Great way to strategize the financial decision-making Russ. Hope my wife does not read this.  

   

I am having VANS delete the NACA and rear PAX ducts from the fuselage skin CNC punch.  I am relocating the NACAs farther forward (up against the firewall) and directing them higher where air ducts are normally designed to be located.  My gonads will be just fine - thanks.  This requires mounting the rudder pedal mounts lower and having the side tubing shortened (the exact distance the mount blocks are lowered).  I liked the dark charcoal powder coat effect, so the weld process will be done preparatory to the last color powder coat.  The rear Pax will have total control from the empennage mounted NACA with “forward flow” overhead air plenum  (Like Mooney, Piper, Beechcraft and Cirrus).  Stole the idea from Ed Hayden.  Size adequacy was not the issue for me, it was the blatantly poor design placement.  However Ed’s team found that a larger overhead orifice reduced the air stream whistle during Max Cool.  

   

Jepp charts can be just too darned important on a hot day (to stay on my lap).  Secondly the routing of the ductwork can allow for removal of condensate before it bubbles into the hermetically sealed avionics cockpit – Dehumidifiers anyone?.  We are going into our 6 months of 85% humidity from the gentle Pacific Ocean Maritime flow just now.
