With the new take-off technique, the pilot no longer has to pick up the banner in the tow hook - a time-consuming and technically demanding manoeuvre. Instead, the pilot can take the banner, already set up for towing, directly from the hanger across the taxiway to the airstrip, and then carry out a normal take-off.
A technical innovation makes the ground start possible. Wheels are mounted on both sides of the banner tube system, so the front part of the banner runs on rollers. This counteracts the Venturi effect which would otherwise be created between the banner and the ground over which it is towed, sucking the banner downwards.
