I think the lecture is a bit short of the LOs. In EASA questions for IR (and ATPL) you would also get questions on mixed ice, on icing in areas of orographic lifting (mountains), in the danger of clear ice building up behind de-icing systems, etc.
@@atplclassYeah bang on. Sublimation works both ways but deposition is only gas -> solid. I think a few CAA and EASA PPL questions use deposition, but not on the ATPL afaik.
Large droplets tend to freeze at higher temperatures closer to 0 Celsius. So they all freeze earlier than the small droplets, so between -20 and -40 all the big droplets have already frozen into ice and we are left with small droplets.
@@atplclass but i thought large water droplets have smaller surface area to volume ratio that would make heat transfer less effective and require colder temp to freeze than small droplets
Really love your tutorials you make it sound so simple
Loved the intro haha 🔥🔥🥶
Your videos are very helpful - thank you!
Amazing videos, thankyou !!

It almost certainly is. These are not complete courses on the ATPL subjects just a bit of additional information on topics incase you need them.
best intro yet!!!
are we looking at the SAT ot TAT for icing?
Usually TAT is more important, as it is the temperature that the aircraft is actually experiencing.
@@atplclass Thank you! Your Videos are a blessing to pass these EASA exams!
For hoar frost it is DEPOSITION not SUBLIMATION.
EASA uses the word sublimation too in the question banks referencing this phenomenon. I agree tho it’s technically inaccurate
as @dhoompie is saying. Deposition is basically a form of sublimation from my understanding.

did you mean deposition for hoar frost?
I thought sublimation was gas to solid but i have it in reverse. Yes deposition or desublimation?
deposition, from vapour to solid. regardless that was a really good lesson@@atplclass
Epic intro ahahahah
can u explain once again that why between -20 and -40 celsius only small supercooled water droplets occur.
Large droplets tend to freeze at higher temperatures closer to 0 Celsius. So they all freeze earlier than the small droplets, so between -20 and -40 all the big droplets have already frozen into ice and we are left with small droplets.
