(NZ) A few straight forward questions
 

Hey everyone, first post here.

I've got my PPL with just over 200 hours so far, but I haven't had a serious straight forward answer to these questions so far, even from the CAA themselves.

What is the correct definition for AWIB?

The CAA CPL Meteorology and CAA CPL Law syllabuses both quote separate things. I've heard all of the following;

-Aerodrome and Weather Information Broadcast.
-Aerodrome Weather and Information Broadcast.
-Aerodrome Weather Information Broadcast.

One more, When is the coldest time of the day?

Several people have said just before sunrise, several said after.
Personally I would say just after sunrise - as the level of insolation is still less than the level of terrestrial radiation at sunrise. So it would still be cooling down. Is this correct?

Thanks in advance guys :)

iDanoo,

In my opinion, AWIB stands for Aerodrome and Weather Information Broadcast.

Coldest part of the day, again, from what I have learnt, after sunrise is the coldest.

For the answer to the first question, think about what AWIB does and how it works. Take each answer and dissect every word, particularly how 'and' modifies the answer. Also think about just what information really is available from AWIB.
Now compare the function of AWIB with ATIS.
The examiner would not expect you to have memorised every term or acronym, but wants to see if you can apply logical analysis.

Second question - USUALLY you would expect it to be colder just after sunrise, but length of morning twilight (e.g. tropics in summer vs high latitudes) and frontal conditions could provide exceptions to that generalisation. Depends how the question is worded and the possible answers given.

AWIB
Aerodrome Weather Information Broadcast
This is because it transmits Weather Information at an Aerodrome by Broadcast.
Take it from me, I build the bloody things.

The coldest part of the night is subject to perception. True lowest temps can be part way through the night and then come up because of, strangely, weather patterns. You would think the coldest part should be just about sunup but it can be an illusion of expectations in your own mind.

King Hell you made it too easy for him! Newbies really need to research for themselves and, to succeed in exams, learn the importance of rtfq.
As for the met question, also terrain and the presence of katabatic winds could modify the answer - probably why CAA persons either disagree or are being deliberately obtuse.
Although I don't recommend no prior study of any aviation subject, with experience and careful analysis of questions and answers on offer, it is often possible to pass multi choice exams with very little preparation time. For those of us not entirely devoted to aviation, a skill worth honing.....

Part 1 "Definitions and Abbreviations" is where you'll find the correct answer.

I've given you a hint for the correct choice.

All right I will bite.
There is no 'AND' in the correct answer! If a published definition somewhere says otherwise, it is a misprint. Not that I have ever looked it up, because - of the three answers - the only correct one is so self evident.
Go listen to an AWIB to realise that it gives basic weather information at the aerodrome and no where else, and certainly provides nothing else.

At NZAP the AWIB there gives aerodrome information such as 'Skydiving in progress' and 'Southern Taxiway is closed' (or something to that effect), as well as the weather information.

If that is the case in NZ then I do apologize.

In our case the voice report is built from a standard set of stored voice codec strings generated by decoding a data string from an automatic weather station, no other input, hence, no other info.

OK, something I have also learned, though the only ones I ever listened to in NZ only transmitted weather.
However, way back in 1998 or thereabouts, NZCAA published a document that gave the definition as aerodrome weather information broadcast, and a google search of AWIB in NZ retains that definition.
Seems that the OP will need to write to CAA for the current official definition.
Not that it matters a sh!t unless sitting an exam where the result is contingent upon that answer being correct!

Some years ago, with NZ ATPL exams all done, I sat all 14 JAA ATPL exams in a short time frame. :eek:

The last exams were VFR & IFR Comms, for which I hadn't studied at all (let's face it, with a bit of flying experience, why would you?) :E

I got wrong the question "what does the acronym 'ATIS' stand for?" Brain just too fried to think, after 13 exams. :sad:

Still passed though. :ok:

(To add something useful for the OP: NZ CAR Part 1 is extremely useful and user friendly. Associate it with the phrase "what does that actually mean?" throughout your NZ career. If you move to Oz, you'll just have to guess most things like that, except what you've already learned in NZ. So learn well!)

@Pharcarnell:

AWIBs in NZ certainly can contain weather and operational information. Same as the NZ NOTAM system will support relevant operational information (e.g. Fuel not available) which is not the case in Australia.

Most AWIBs in NZ I've listened to use a computer synthesised voice for both weather and operational information, whilst most ATIS' use a set of pre-recorded words & phrases.
