I passed PPLA a few months ago with 82%.

Look up 1 in 60 explained on youtube, there are so many videos. But it is actually very easy. Do not get bogged down on the dumb stuff. You are in cockpit playing with a paper map whilst being tossed around in a plane older than your dad. if the youtube explanation calls for an abacus and a personal meet and greet from Pythagoras himself, its prob too complicated.

Here is an example I just made up on the Bourke Wac

U r flying plane from Lighting Ridge to Bollon.

You pass over the top of Ballandool aerodrome 33nm into your flights, oops.

What heading correction do you need to make to end up at Bollon?

We need to do two 1 in 60 calculations using the formula: d x 60 ÷ D

Little d is the 'little distance,' so the distance you are offtrack (line between the track and Ballandool)

Big D is the distance of the track.

Find for the first triangle = 7 x 60 ÷ 33 = 12.72deg

Now this is great, if you turn 12.7deg to the right, congratulations, you will be tracking parallel to the flight path. You won't end up at Bollon, you will end up at Moorindoorah. Have fun with that.

Find for the second traingle = 7 x 60 ÷ 55 = 7.6deg

Now, this is just the correction you need to make in addition to 12.72deg to turn you back onto Beautiful Bollon.

Add the two together = 20.32deg.

You will need to make a correction of 20 degrees to the right.

Tips:

1. Use the WAC. WAC is the best. VTC / VNC / sectional charts you look at only when close to a big aerodrome. But for PPL exam you will never need anything others than the WAC.

2. Use a ruler that has the WAC distances marked on it
