Cessna 120-140 Association

is it ok to fly with the windows open??? The mechanism is pretty spindly.

I do often, but I'll wait till I get to cruise flight to do so. Just be aware that anything on the shelf behind you will blow around. My windows open all the way and rest up against the wing.

My passenger's side window was screwed shut and there was no latch when I purchased my 120. Later, I discovered that the hinges were in place, and the window swung open easily. I added C150 style latches on both sides and now open the windows in flight regularly. I also added a rubber strip on the outside of the lower frame in case it bumped the wing.

Maybe the best part is the fresh air while descending and landing on +90 degree F days. Hands down better than the original configuration.

I too wait until I'm cruising before switching to the open configuration.

Cheers,

I have a very original 120 with the original window latch on the pilot side. I taxi, take-off, climb, cruise, descend, land, etc. all with the window open. No buffeting or anything on the window/latch; but as others have mentioned, stuff on the hat shelf will get blown around if not secured.

For what its worth, a buddy has a 56' 172 which appears to have a similar latch system to the 120/140s. He has pulled the rivet on the bracket of the door. Damage indicates the rearward airstream pulled the scissors too much. After 64 years though I don't think you can complain too much.
