Long time lurker, new poster. I travel frequently and on two recent flights aboard a 757-200 I noticed that during cruise, the inboard flaps remained partially extended - perhaps 3 - 4 inches - for the entire duration of the flight. It occurred to me that this was unusual and I asked my carrier about it; they took my question seriously and said that it was normal for certain flight conditions. I've attached a photo.
Any 757 drivers out there who can elaborate on this? I was very surprised by this, as the wing when fully cleaned up should be optimized for cruise configuration. After landing, the flaps were fully retracted.
