Flight Planning Across Magnetic Variations
GG, Bring give them a heads up and bring them a chocolate or something nice and they will usally be alright. They don't really like people turning up out of nowhere.
Sheesh it's not like she is doing you a favour or anything! She is doing what she is paid (probably more than me at the time) to do.
As for turning up out the blue? NO prearranged whenever I used to go in there.
I'd be trying to work out a fuel figure for the payload I'd been given and she would be standing on the ladder with the nozzle in the tanks sighing and huffing and puffing. Every couple of minutes she'd clamber up the air stairs and rudely ask me "have you figured it out yet"!!!
She needs a one way ticket back across the Tasman and quickly!
On the right track, TinKicker, Grivations are the grid equivalent of Magnetic Variation.
But what's the (green) line called that joins up the same value grivations?
(and as an aside, the small black numbers on the map are spot heights).

It's not my first choice of route for a trip either, but it's purely a business trip. Have to inspect properties in Rocky during the day then overnight at families at Bundy on the way back.
I will give both aerodrome operators a call in the next week or so and report back if I have any issues. As both of them have shell i expect they'll take credit card or shell card. fingers crossed anyway!
Also, anyone know about the state of the YBUD grass strip at the moment? I guess i'll just ask when I call anyway - but a pilot's opinion is good too!
thanks again.

Most, if not all, Shell bowsers are now Credit Card operated so you will be fine there also.
Can't say I have ever found the refueller at Rocky to be of any help either.

Had to go back to the Book* for this one....as there has been too much stuff added since this one was.....a long time ago.
ISOGRIV - a line of a chart joining equal points of grivation
*Air Navigation Vol II - AF Manual 51-40 March 1955 (original copy)

PS - Looks like Masif beat me to it by a few minutes.....congrats

Yep, Isogrivs they are... The GNC map extract is a hundred miles to the sw of the south magnetic pole.
And your tome's definition correlates with my Arctic Air Navigation, by the Canadian Defence Research Board.
Sadly in these days of DIR TO on GPS it's a dying art. . I still get to use it in anger though.

jnicholas, I am kinda curious - how did you work out tracks required and headings to fly for your PPL navs?
Did you not do a navex that crossed Mag Variation lines?

I did a fair few nav's to do my PPL. never did we go all that far notrh / south though to cross more then 1//2 a degree or maybe a degree in variation. A lot was done from the sunny coast out towards oakey, amberley, kingaroy etc. And never have I done a full stop at an away field to re-fuel / supply. Thus, the amateur questions!

I have a basic knowledge of maps and land-based navigation etc so have I missed something?

- forgive me if I'm wrong but isn't your ppl supposed to include a 300nm flight with a stop at 2 pts??
Maybe I'm getting confused with a company syllabus and the actual day vfr syllabus...
In any case happy flights...

I believe the syllabus only states stops, ie; full stop landings, doesn't mean you have to refuel. Although it would make sense to have an instructor with you the first time you want to try to decipher how to work a bowser!
I get a warm feeling every time I see someone struggling to pull out the hose when it's in reverse gear. Makes me realise I'm not the only idiot out there!

Ouch
I am a bit shocked then that you can get a PPL without ever having got out of the plane at another airfield.
OK the getting out bit isn't all that hard.
But it's clearly left you without some form of real life flying experiences and airmanship (Not having a dig at you personally)
More of a school issue me thinks as it's not really trained you how to USE your PPL all that well.
best of luck with the trip and hoping the forums have pointed you in the direction that your instructor really ought to have.

I hate to be one of those people who say, "Things were better in my day", but .........
I spend a lot of my time and energy training young people for a profession and I can tell you that they graduate with superior knowledge and skills to enter their chosen profession than I , or most of my contemporaries did. I get enormous enjoyment and satisfaction from working with these young people and believe that we do a very good job of equiping them to cope successfully with their first 1000 days (call it 3 years) in the profession.
However, in general, this does not appear to be the case with flying training in Australia.
I got my PPL 38 years ago, and have always felt that I was well trained to fly a single-engine GA aeroplane anywhere in Oz that I chose to go. Like most new "graduates" I lacked a body of experience, but I was well equipped to gain that experience.
PPL Navs were:
1. Archerfield - Gympie - Archerfield (2.25 hrs - dual)
2. Archerfield - Stanthorpe - Casino - Coolangatta - Brisbane - Archerfield (3.25 hrs - dual)
3. Archerfiel - Dalby - Brisbane - Archerfield ( 3.2 hrs - dual)
4. Archerfield - Maroochdore - Archerfield ( 2.1 hrs - solo)
5. IF (2 hrs - dual)
6. Archerfield - Kingaroy - Brisbane - Archerfield - Brisbane - Toowoomba - Archerfield (5 hrs - ICUS)
7. Archerfield - Coolangatta - Goondiwindi (refuel) - Archerfield (5 hrs - solo)
That was the syllabus in the "old" days!
Dual navs were in a PA28, solo navs in C150.
No having a go at you jnicholas, just your training - and the system !

Yes, you have.
The Geographic south pole is at 90 degrees south. Everyway is (true) North. The yanks have a base there.
The Magnetic South Pole is as suggested around 65S, over water and almost due south of Tassie, not far from Dumont D'Urville. This point moves around a bit. It used to be over land as that's why Mawson, Ninnis and Mertz began their long trek to "find" it 100 years ago. This is where the flux lines (to which your compass aligns) are vertical. Your compass just spins slowly and quietly to itself without a care in the world.
Then for trivia nights there's the Geomagnetic South Pole is a point that dipole of a standard theoretical magnetic field of the earth extends outwards. It's currently just a bit south from the Russian research station of Vostok. This is a theoretical point and nothing happens there except that it's rather chilly.
edit - more reading here but beware there's a slight mistake, or incorrect wording. It says that the South Geographic Pole moves 10m a year. The pole does not move at all, rather the icecap and all on it (buildings, neutrino telescopes, runways) moves 10m a year. Thus the peg in the ground needs to be shifted by 10 metres every year. A rather glacial example of relativity I guess.
