Default Canopy free soaring

Awww...* I thought you were gonna do it in the lee of Mt. Washington on
New Year's Day. :-D

Plenty of pilots have lost there canopy inflight and reported the plane flew just fine without it.

I'm motivated to test that bit of woodsy lore. Checklist items: boxer briefs, sunscreen, full face shield motorcycle helmet, and a parachute.

Other than drag, is there any reason to not remove my canopy and go soaring? Experimental airworthiness.


What type of glider?

Why wait until next Summer?
The open cockpit regatta is held every New Year's Day in Tehachapi.


I'm told you haven't really flown in an "open cockpit" until you do it from a
winch tow off a frozen lake. The closest I've come to an open cockpit was racing
open wheel Formula Vee cars, and I learned you really want to have that small wind
screen deflector in front of you, otherwise the force of the wind on your head can
make your neck very tired, very quickly.

I don't know about the frozen lake, but I've enjoyed winch launching in
my club's Slingsby T.21 - not only open cockpit but side-by-side seating
as well. Very pleasant flying on a summer day. During the longest day the
T.21 is first to be launched and last to fly because its not bothered by
canopy misting.

The T.21's airbrakes are about as ineffective as those on a 2.33 and its
performance is similar, but its cockpit ergonomics are better and the
instructor's vis and comfort are better because he's sat alongside the
student. But the design is 20 years older and all in wood and canvas.

I've not done the following, but clubmates who have tell me that its slow
enough to fly a circuit without turning at all on a windy day - winch
launch as normal, slow down to min sink so you're blown backward just
past the runway threshold, then put the nose down, speed up and fly
finals as normal.

My first training flights were in a Slingsby T21B many decades ago. It still seems weird being in an open cockpit with a full panel of gyro instruments!

When Dan flew the Diamant open cockpit, believe he came up with the idea to give turn signals before rolling into a thermal, as you'd do on a bike.

EXP airworthiness does not mean you get to change things that influence flight handling or W&B without "recertifying" the machine in the new configuration.

Yanking the lid off will certainly change the aerodynamics, unless it is one of the SGS series that allows pilot choice with various factory equipment.

But that only matters if you want to be able to have your estate collect the hull value from insurance after you become a test pilot.

I'm figuring you just wanted to yank chains, since daylight ends earlier all of a sudden this week.

For a glider that is certificated in EASA (EXP airworthiness in the USA), a glider that has a canopy designed to jettison with the intentional or unintentional release of two levers, and where there is a history of glider canopies inadvertently jettisoning in flight... I'd expect that 'lose of canopy' would have been anticipated by the designers and regulators, and maybe even tested in flight prior to certification. Maybe not.

Does JAR-22/CS-22 require a glider to fly 'just fine' without a canopy? (Even if it does, I understand that there may be regulations that prohibit flying that without a canopy with prior intent. Any guesses at what regulations might apply?) I've heard stories about passengers jettisoning canopies in flight, pilots that have accidentally jettisoned canopies in flight, and I've been told that a glider will fly 'just fine' with an unlatched canopy that is flapping in the breeze, and that might progress to total 'self-detachment'.

you just wanted to yank chains


I thought it might be fun to discuss the possibilities of flying without a canopy. So far, so good. Let's keep it light and enjoyable.

Can be done. Here's a guy who flew a supersonic fighter, with throttles
accidentally locked in afterburner, no jet time, and no canopy.
