flaps
Be very careful doing this. It's not approved in our FCOM and FOM. When you're not used to putting the flaps down at that point, you can easily forget until you get a CONFIG FLAPS warning when you advance the thrust levers.
***Actually it is approved in our FOM. I just read the other day, that in certain conditions it would be wise to taxi with the flaps up (snow, ice, etc) then when clear of debris put the flaps down.
I also read that if landing in snow, ice etc... it is also wise not to put the flaps up, only to 20 and do a good post flight check to make sure ice and snow are not all over the bute doors...if so, leave them at flaps 20 and call for the ice man.
