Dominie "Smog"
In light of the recent Doncaster "donkey derby" thread, I thought perhaps some learned gents (or otherwise) might be able to help clear up a long held headscratcher. Once upon a time I rode shotgun in a Dominie T1, medium level, we ferried an F-4 crew between Colt and Wattisham I recall. I think it was upon each successive takeoff that the old girl seemed to leech smog through the floor vents which partially filled the cabin. As a novice aviator at the time I did my duty by querying my imminent demise with the boys up front, at which they smiled heartily as if it happened de rigeur. 
Well, wossup? Was this "design feature" typical of the Dom? And did it occur aboard other types? And by the way, when you were flying empty, how did you manage when the only VOR/DME was up the back?

not smog, condensation through the airvents. You get it on some civvie jets if the conditions are right.

Well I sort of guessed it was benign, but would anyone care to explain the science? What system do small jets lack that the big jets have? It was no small beer, like firing off a CO2 extinguisher

As a RHS stude (AEOp) for a short while on Doms, I'd take VOR fixes regularly - can't be sure this late in life whether DME was available.... I vaguely recall that it was, but probably not used by stude. (They liked to see how small a triangle our fixes produced, rather than a simple line with a tick mark being drawn)....so VOR available at least whilst up the pointy end.

That brought back a few memories.
I thought the Dominie was bad until I moved onto the F4. It was a case of max chat on the heater before any descent. Anything less resulted in a barrage of high velocity icecubes.

daveJB, DME was controlled and displayed to the nav studes alone. The ADF was also controlled by the nav but the pilots could see the display.
On the pilot's resettlement course - Civil IRT - they had to take a nav along to tune the ADF. The pilot had to check the beacon coding but was wholly reliant on the nav on speed of tuning etc. As I could do it pretty quickly and was not otherwise involved in teaching studes I got a good number of jollies out of it with Berlin a few times etc.

Did my civil IRT 21/9/88 in XS738. Wasn't you down the back per chance was it Pontious? Finningley - Stansted - Bedford - Stansted - Finningley. Positioned the aircraft to Stansted to pick up CAAFU examiner, IRT on 1 pilot Stansted - Bedford, my IRT Bedford - Stansted, pay cheque, drop off CAAFU examiner, fly back to Finningley where the barrel was waiting in the crew room. Happy days.
Brings back memories of my first ever flight in a jet. I was at Air Cadet camp at Stradishall in '66 and was taken up on a night flight in one of the shiny new Dominies. Shorty after take off someone shouted "smoke in the cockpit," and before anyone could react it had gone.

BB, no, I don't remember the beer.
I still had a course then. My jollies were a year or so later so you don't owe me any

Dornier Ground Fog
Here is a "ground fog development" I saw in a Do 228 (un-pressurized) during the departure from Manila:
It almost became IMC in the cockpit a few minutes later

Wow, never heard of this phenomenon before. Must make the pax a bit nervy!!
Add one wipe rag to the pre T/O checklist.
Leaves me wondering, do such jets have a windscreen demist just like in a motor?

Cooch, often experienced in Airbus as well, quite spooky seeing the 'smoke' pouring from the overheads.
GeeH'
Vampire 9' had the same problem. The "Godfrey Cold Air Unit" fitted for MEAF and not removed on return to UK, fired high-speed-slush' when descending through Lincolnshire cloud on a QGH. Very cooling!

Well apart from the obvious cockpit visibility issues(!), I would have thought that corrosion/electical problems might eventually ensue.
Also brings to mind an immediate conflict of interest whereby airlines try to save fuel by short heating the cabin air. Or is that just a myth?
Any thoughts/anecdotes?

Coochy, not heating but conditioning. I believe where 4 conditioners are fitted only 3 might be activated thus giving a slightly reduced, but acceptable, air quality.
