Estimating the Force of Impact During an Aircraft Crash Based on the Pattern of Injuries

Description

The force experienced during the crash of an airplane can be estimated based on the pattern of injuries seen. Investigators from the Armed Forces Institute of Pathology (AFIP) developed these based on their experience with different types of aircraft accidents.


Force in G's

Injury

15 - 30 G

vertebral fracture

25 - 30 G

lung contusions

30 - 35 G

rupture of the atlanto-occipital membrane

>= 50 G

laceration of the aorta, skull fracture

>= 80 G

transection of the aorta

>= 100 G

fracture of the pelvis

>= 350 G

body fragmentation

 

where:

• G = force of gravity
