Well...for what it's worth, here I go!!!
Climb out on upwind to 500' AGL...climbing turn at no more than 20deg AOB.
Crosswind should be perpendicular(90 deg) to the extended centreline, and flown until a/c is at 45deg from the upwind threshold.(regardless of altitude)
downwind should be at 1000'AGL and,in a c152, runway should be 2/3 up the strut.
maintain 2350rpm until turning base, then reduce power to 1500 rpm and take 1-2 stages of flap(normally 2, but if a strong headwind on base...stay at 1 stage).Carby heat should be applied IF the conditions dictate that it should be.
A mid base check should be made to check hi/low and adjust accordingly(mid base should be at 750'-800').
Turn onto final(no 's') begins at 600' at wings level should be at 500'(note: these heights are guidelines only and should not be used in place of turning onto extended centreline)
On final, maintain centreline all the way down, ensuring full flap(if using it) is selected by 300' AGL.Power should be used to adjust rate of descent...and attitude to adjust for airspeed.
Carby heat(when used) should be selected full cold on late final...and before touchdown, ensuring full power available for go-round.
NOTES:.....
1/ from downwind turn(in a single-engine a/c) the a/c should be able to glide back to rwy in case of eng failure.
2/ a/c should be climbed at best rate of climb speed.
3/ fly the a/c for the day!!!not by rote!!!
4/ have fun!
