Which of the following is NOT a drop method in airdrop operations?

In airdrop operations, each method of drop is characterized by specific velocity thresholds that relate to the type of cargo being delivered and the conditions under which the drop occurs.

High Velocity drops involve weights that descend at a rate of 70-90 feet per second, which is typically used for the delivery of military supplies or small equipment that must rapidly reach the ground. Low Velocity drops, which occur at speeds less than 28 feet per second, are suited for fragile cargo that requires a gentler landing to avoid damage.

Medium Velocity drops, at around 40 feet per second, also cater to certain types of loads but do not align with the extreme conditions that either High or Low Velocity drops accommodate.

The term "Excessive Velocity," on the other hand, is not recognized in standard airdrop operations terminology. A drop exceeding 90 feet per second would be considered unsafe and impractical for delivering supplies or equipment due to the potential for damage on impact. Thus, this method does not exist within established airdrop procedures and distinguishes it from the other recognized drop methods based on defined operational standards.
