Down wind checks.
No, no, no!
Enter downwind. When abeam upwind threshold, CARB HEAT ON and call downwind.
Now do:
B - brakes off (park and toe)
U - undercarriage down (fixed)
M - mix rich
LOOKOUT around, esp for traffic joining downwind and base
I - instrument check, inc. Ts and Ps
F - check fuel contents and fuel pump ON
F - flaps inboard
LOOKOUT
H - harnesses SECURE
H - hatches SECURE
Carb heat OFF
This has two distinct advantages over the horrible BUMFITCH check.
Firstly. the carb heat is applied for most of the length of the downwind leg, thus melting ice and is good for when you come to fly types that like to ice up, e.g. Warrior/Super Cub 150.
Secondly, the student is taught methodically to LOOK OUT of the window for traffic whilst doing the checks and co-ordinate accordingly.
HTH.
