Hello.
I found during my early days in a 152 that I had a tendancy to look over the spinner and think that this was dead ahead.
Result - you think you are off to the right and you come in to the left. Hmmmmmm.
A concious effort to look dead ahead (but not light a frightened rabbit!) did the trick.
Another classic is to fly left wing up because the curve of the top of the instrument panel lulls you into thinking that this is what is really level.
I think perhaps I could do with a gun sight or something...
Cheerio,
By the way...
The look dead ahead thing is clearly not going to work in a cross wind - but it was just something I did to get out of the habbit of looking over the spinner.
You can all stop laughing now.
Cheerio,
