Now, I quite like weather. I think I’m reasonably okay at looking on charts or up at the sky to see what is generally going on.
However my Met ATPL is turning it into an almost pathological fear. A 90 question paper with an active database of 1000 questions means you need to know an awful lot of facts.
For example did you know and this is an active question, cold occlusions mainly occur during Summer? Nowt in my textbook, though Oxford’s CD does mention it t.g.
And I still can’t get an easy method sort for corrective altimetry (different settings, for temp etc). 😮
All this it has to be said is having psychological effects, making me feel like I know very little and putting me off revising (which is a barmy thing to do).
Is there solace out there? 😉

They key here mate, as I have found, is to do the feedback with other chums who get “it” and you soon discover a clutch of themes running through the bank. Learn the themes and you probably can crack most questions thrown at you. 1007 is just too much to remember.
Now I need to crack Performance and I may yet scrape through this term with passes. 🙂

Neil I have rather a large MET feedback book, I used this instead of the QB, I went through each section twice and it got me through the exam no problem, you are more than welcome to borrow it if you want.
Send me a txt and we’ll arrange how we are going to get it to you if interested

Neil Answer C fits best, the cloudbase obviously lowers as the front is approaching, starting with Stratiform cloud, Cs and some Ci, then this becomes As and then Ns, then ahead of the warm front the precipitation is falling from the Ns in the overlying warm sector which will cause some broken St fractus below it in the cold sector.
Remember for altimeter problems, work out the barometric errors first, then correct for temperature difference from ISA, see if this is of any use.
There is a 4% height difference in true altitude from your indicated altitude for every 10ºC difference in air mass temperature, that is for every 10ºC of ISA temperature deviation.
Example:
Barometric corrections show that at an indicated FL50 the indicated altitude would be 4800ft in ISA conditions. The air mass temperature is ISA minus 15ºC. What is the true altitude?
Solution:
The Rule of Thumb correction is 1.5 x 4% x 4800 = 288ft. The air is colder than ISA, so the altimeter is overreading, and the true altitude is 48000 – 288 = 4512ft
Remember Cold air will make your Altimeter overread, and warm air will make your altimeter underread

“corrected for temperature” I’m rather haphazard on the method.
Volare proving useful. Tooooo many questions to undergo online.
Here’s one that got me yesterday:
Why do very low level clouds form ahead of a warm front?
1. warm air moving over a cold surface
2. saturation of the warm air by rain falling into it and evaporating
3. saturation of the cold air by rain falling into it and evaporating
4. reduction of outgoing radiation due to clouds

It is fairly easy to remember how to do it, I’ll get my notes out and see if there is a good way of remembering it, how are you with the QFF/QNH ?

You’re unholy! :diablo:
Well it transpires that the true/indicated altitude correction questions are not as hard as those we are being tested on in class. Got any decent notes on this for working stuff out?
I’m more of an aeroengineer/chart type bod.

Neil
MET is generally one of my stronger subjects, if I can help in anyway just shout up, if you go through the Oxford MET CD and the BGS question bank you will be fine, what I found good was reading the manual twice AND going through the CD.
