How does an aerial banner towed by an airplane stay in the correct, upright position?

Question:


Answers:

is there any flying schols giving cpl in 5 months & are they cpst effective?

The above answers are all correct, plus there is a weighted keel at the bottom edge of the sign, where the Bridle attaches to the tow rope. The keel acts as a rudder, keeping the sign at an angle most visible to the public.

i own 6 airplanes do youall own a airplane?

IIRC its a weight in the part where the tow ropes attach to the banner

Where on the web can I find plans & facts for hovercrafts?

Each letter in the banner has a small weight on the bottom. This helps the letters stay upright. Adidtionally, there is a small drogue chute (basically a miniature parachute) at the end of the string of letters which stabilizes the banner and keeps it from twisting and snapping in the wind. Without the drogue, the banner would snap like a flag in the wind. These weights are very small, though; a whole banner weighs something on the order of 25 pounds, depending on how many letters are in it.

What's the better demonstration team, the Blue Angels or the Red Arrows?

It is aerodynamically designed so that it stays upright all the time, just like the plane is designed. The banner has weight on it's bottom tail end and airspeed keeps it stretched out. Then there are cut out flaps throughout the banner that direct the air around it so that it does not flap like a flag.....KECK
