I use to see Cubs running banners all day long when I worked at HWO
. I'll use what was done at the grass field HWO
as a reference. (The runways aren't used there)
On the Cub there is a cable that's about 60ft long that it attached to a hard point by the tail wheel. At the end of the cable there is a simple 3 prong grappling hook that weighs about 10 lbs.
1. The aircraft the will enter the Pattern at about 600-800ft.
2. When the aircraft is lined up with the banner on the ground the throttle is cut and the aircraft will enter a steep dive at about 30-40degs.
3. At about 100ft the Pilot pulls the stick back hard and goes full throttle.
4. By the time the aircraft it at a positive rate of climb, it sunk to about 50ft and the nose is about 15degs past the horizon.
4a. At the same time the Hook swings to the ground, and if the timing was right should hook the towcable on the banner.
5. The pilot keeps the throttle at full and pulls the nose to about 25degs and keeps climbing.
6. At about 200ft the banner (if caught) will lift off the ground and the Cub will go fly it's route.
When droping off the banner the aircraft enters the pattern at about 500ft enters a shallow dive at 20degs, The cable attached to the aircraft is released at about 30-50ft.
The Cub will then land and attach a new cable and takeoff and do it all again.
Some Cubs can carry 1 or 2 extra cables so landing is not needed but it's not common.
On last Feb 14 at HWO
there were 7 Cubs flying banners from 8:00am to 6:00pm, With a banner being picked up about every 10mins. We figured they flew around 200 banners. (On a average day 2-3 Cubs will only fly about 35) The Ft Lauderdale Air&Sea Show is a busy week also.
