When training students, I make them fly a square pattern. On our field it is along the edge of the trees on the far side, in front of the trees on the left, then across the runway. Right side trees are a long way away, so have them make rectangle symmetrical.

What this does is let them get familiar with the size of the field (besides it is a good size pattern.) They will get familiar with judging distance as far as the field limits. Also, it forces then to "fly the plane where we want" and not where it happens to go.

Two suggestions:

1. Fly over the "problem area" in a normal pattern. Have someone with more experience tell you if you are too far or too close.
2. Have someone else with a similar plane fly over the area. Or have them fly your plane over the area.

It is best to fly 2-3x the height of the trees. Too high is more difficult to judge distance. Work on your judgement while flying, not later on the approach.

My students ralrely get confused on landing. I drill them on "Flying the pattern" I know they get bored with it, but it needs to become automatic.

Landings are just the same pattern but cut power at end of downwind leg. Then they fly just the same and finish the pattern to the runway. Most of my students first landings are surprises. I have them fly the pattern and cut throttle and do an approach. Go around until they always come in where we want. Then I'll tell them, "OK, don't go around, just keep it level and LAND."

Almost all of my students do near perfect first landings. Suprises them: "I thought landings were hard". No, landings are easy when you put the plane where you want. Hardest part is me holding that stupid trainer button for hours while they "Do the pattern."
