The objective of this study was to determine how much pull force a free-falling man could exert on the ripcord handle of a back-pack parachute. There were 41 free-fall parachute jump tests conducted using 11 USN and 11 USAF test parachutists in order to ascertain the maximum forces which can be exerted on manual ripcords. Subjects exited an aircraft at 10,000 ft (MSL) 110 knots (IAS), went into free-fall attitude and then, in accordance with approved Navy or Air Force procedure, exerted maximum force against a dummy ripcord handle (containing a strain gage), which was anchored to the parachute harness. Other physiological and force parameters were acquired through 9-channel FM/FM bio-telemeters. Under the conditions of this study, 22 military parachutists generated average ripcord pull forces of 115 pounds during 41 actual aircraft baill-outs with observed values ranging from 40 to 210 pounds. Larger subjects generated significantl greater ripcord forces than lighter subjcts. For the USAF assemblies, the actual force required to withdraw the pins from the cones averaged 42 pounds.
