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

Answer 1

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.

Answer 3

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.

Answer 4

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

Answer 5

Is the vehicle equipped with a wiper relay??? I'm not familiar with the Vauxhall, but I was told it was the predecessor to the current US Pontiac G6. If the relay is going bad, then it could be preventing the wipers from returning to the off position. The Pontiac G6 has the 3 part system, switch, relay/module, and a motor. To test the motor, you can made leads for the battery, find the motor harness and attach the leads to the motor, If the motor works fine, then it's a module or the switch itself. Good Luck

Answer 6

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