Default Unlatch canopy

Any information or thoughts on what will happen taking off with an unlatch canopy?
Slider vs. Tip-up.
I'm pondering installing a 'canopy unlatch ' light.
Yeh Yeh, I know check-list.
But, I'm curious. If you have done this, no need to confess.
Just tell us what you 'think' would happen.

That search button will bring up a lot of threads.

Basically, the tip-ups just float open about 2". No big deal. As part of my test period I took off with it unlatched and it opens just about the time you rotate and start climbing. Of course, anything that can be sucked out might not be there when you land.

At altitude, if you slow down, put down the flaps, you can close it in flight.

The sliders are a different story. Maybe someone with more experience with them than I will respond.

Default One of my first flights

I took off with my sliding canopy closed but unlatched. When I finally noticed it due to the increased noise and wind I slowed to 80mph and tried to pull it open slightly and latch it. I could not budge it.

The benign effects explains why not much is mentioned. Out of 9000+ RVs, I figured more than a couple of oh #%!* had to happen.
I think I'll shelve the canopy light idea.

Better to put in a "fly the plane, don't start screwing with it, and land" light.

You might encounter some posts about canopies coming off if unlatched. As far as I know, that's limited to the single-person-wide airplanes that have tip-over canopies that open sideways, hinged on the side.

Angry I confess

I forgot to secure my tip up canopy but quickly realized it at rotation. At about 50 feet in the air I realized there was plenty of runway in front of me, landed and then taxied to the end (5,600 foot runway). Closed the canopy and taxied back for another take off.

This taught me again to always do a safety check prior to entering the runway and also reaffirmed the short takeoff and landing requirements of the RV7A.

Yea, always fly the airplane first. Everything else can wait.

Done this a few times with my slider, where it is almost, but not quite closed and unlatched. Nothing really happens in flight. If you go to slow flight speeds you might be lucky enough to get it latched (ive done it), but its really hard to do.
