    A safety factor of 1.5 is required for certification giving an ultimate load factor of 7.0 G to allow for material variations and inadvertent atmospheric conditions. Because of its light wing loading, the 2-33 can develop very high loads if speed limitations are not rigidly observed.

    A-CR-CCP-402/MB-001 SCHWEIZER 2-33 AOIs CAUTION See Figure 4-2. Combining a forward slip with use of full spoilers will result in a very rapid rate of descent, at times increasing to 1,000 fpm or greater. Waiting for the exact altitude before removing the control inputs for the slip will often result in descending below the intended altitude.
