T/O config warning
flying the 737 NG for an airline in India...
have to admit I do the quick advance of one thrust lever to vertical and back to check the config ...although it's not SOP or authorized in the FCOM ....
did have one low speed reject earlier in my 737 flying due to a faulty speedbrake lever microswitch and this quick check just before lining up saves a lot of trouble me thinks....
take care and masalama.
