Class A, B, And C External Loads

Class A External load operations include carrying cargo that does not extend past the landing gear. This includes tasks such as carrying cargo racks and other similar loads. 

Class B External Load Operations involve transporting cargo that is free of the ground or water and can be safely jettisoned if necessary. An example of this type of operation is hoisting air conditioning units or similar equipment.

Class C External Load Operations refer to transporting cargo that remains in contact with the land or water and can be safely jettisoned when required, requiring precise handling and coordination. An example of this operation is wire pulling.
