his only applies to 739ERs for their flaps up landing. There's no note for 800s in our FCOM.
Although ERs have a lock as protection which prevents moving the lever beyond flight detent in flight.
Thanks, Mmrassi.
It's interesting to see how other Boeings handle "flight detent". The Boeing 767 uses air/ground signals into the Spoiler Control Modules. The lever still moves through the same range. The 777 uses a similar system (with air/ground input). The 747-400 uses an electromechanical lock in the lever assembly (activation logic is also based on air/ground logic) so you get a restriction in lever movement. I don't see why flaps should be involved in the logic on a 737-900ER. Is there also an input from the landing gear?

Is there a similar note for a gear up landing on the 737-900ER? Hopefully there is not an error in the FCOM.
