Could anyone describe (or direct to usable documentation) me aircraft configurations? What does it mean clean configuration, configuration 1, 1+F, 2, etc... Is there any section in FCOM's describing it in clear way?

A clean configuration is a configuration where landing gear, flaps, slats, spoilers etc. are retracted.

1, 1+F, 2, 3 and FULL refer to the level at which the flaps are currently deployed:

  • $\begingroup$ Thanks for clear answer, it helps a lot! Could you clarify, is it taken from fcom (exact chapter) or some other documentation? $\endgroup$

  • $\begingroup$ Do you remember whether the 1+F position is selected during extension or retraction? $\endgroup$

To clarify lever movement direction and actual flap/slat combination, I attached a more detailed snippet from the A340 FCOM § 1.27.50

Note that in-flight selection of 2 above 193.5 kt equals config 1* (same as 1+F but with more slats).
