  1. UH-60 Performance Planning (Alternative or Sling Load) 1-212 Aviation Regiment Fort Rucker, Alabama 36362 Version date: April 2007

  2. Terminal Learning objective (TLO): At the completion of this lesson the student will: Action: Complete an H-60 Performance Planning Card, Alternative or Sling Load Configuration, DA FORM 5701-60-R. Condition: As a UH-60 aviator. Standard: In accordance with TC 1-237, TM 1-1520-237-10. Safety Requirements: None. Environmental Considerations: None.

  3. TYPES OF DRAG PARASITE (FLAT PLATE) DRAG CREATED BY NON LIFTING PORTIONS OF THE AIRCRAFT PROFILE DRAG IS FRICTIONAL RESISTANCE OF THE BLADES PASSING THROUGH THE AIR TOTAL DRAG INDUCED DRAG CREATED THRU THE PRODUCTION OF LIFT DRAG FORWARD SPEED
