subsequent gliders attached to the glider’s tail tie-down point. The minimum length of these
ropes shall be 30 feet. To prevent structural damage to the lead glider, a maximum of six
gliders are to be towed at once and this number is to be reduced when rough terrain or winds
dictate.
TOWING BY TOW BAR
8. The 2-33 glider may occasionally be moved using a tow bar attached to the rear tie-
down point provided there are no occupants in the glider and the terrain is smooth. Occasional
use means several times per aircraft per year vice frequent use of several times per aircraft per
day. Frequent use is prohibited. When moving the glider with a tow bar, the tow bar itself
provides the steering and braking. Normally, only one person is required at one wing tip to
maintain wings level. When manoeuvring around other aircraft or into/out of hangars,
personnel shall be positioned at each wing tip to ensure proper clearance.
9. The only tow bars authorized for ACGP use are those manufactured and identified in
accordance with Drawing QETE-00063. This tow bar has been designed to limit glider
structural damage and no tow bar modifications are authorized without approval from the
National Technical Authority (NTA).
TIE-DOWN
10. All locations where gliders are left unattended for more than a few hours are deemed to
represent a high wind hazard.
11. Based on a 600 lb empty weight, the typical 2-33 glider facing into the wind may be
subjected to lift forces ranging from 150 lbs to 3,350 lbs. See Figure 6-2 for methods used to
minimize lifting forces.

12. Representative Glider Tie-Down Methods. The most suitable tie-down method is
dependent upon the combination of wind conditions and length of time.
a. Item A at Figure 6-2 depicts a tie-down method suitable for calm winds or short
periods of time such as a Flight Line Tie-down. This method should not be used
in high wind conditions because of the increased angle of attack created by
leaving the tail on the ground.
