SCOPE This document contain
5、s information that can be used by the air transportation industry to provide passengers with consistent “Brace for Impact“ positions in passenger safety information and briefings. This information is intended to reduce the potential confusion passengers may experience upon being presented with diffe
6、rent “Brace for Impact“ positions as they travel on different aircraft or on different carriers. This document does not address child restraint or situations where adultpassengers are seated behind fixed tables.1.1 Mandating and Recommendation Phrases “Shall”: The word “shall” indicates a mandatory
7、criterion.“Should”: The word “should” indicates a criterion for which an alternative, including non compliance, may be applied if it is documented and justified. 2.

CONSIDERATIONS AND RECOMMENDATIONS 3.1 Seat Configuration Most passen
14、ger seats are situated behind another passenger seat, a vertical bulkhead, or a passageway. Depending upon interior configuration of the aircraft and the size of the passenger, the passenger may or may not be able to reach the surface in front. This requires that information be conveyed on at least
15、two brace positions for passengers in forward facing seats; one for conditions where there is a seat or other cabin furnishing within reach in front of the passenger, and one where there is no seat or other cabin furnishing within reach in front of the passenger. Occasionally there are rearward-faci
16、ng seats on both transport-category aircraft as well as on general aviation aircraft. Further, some general aviation aircraft are equipped with sideward-facing seats that may be occupied on takeoff and landing.3.2 Brace Positions 3.2.1 Forward Facing Figure 1 provides the important features of the t
17、wo brace positions for use by adult passengers in forward facing seats. Figure 1 may be used as a guide in preparing safety information media. It need not be copied exactly, but the intent of the illustration (as indicated by the numbered features) should be maintained. These features shall be provi
18、ded in all passenger safety information materials and briefings (reference ARP1384).3.2.2 Rearward Facing The brace position that can provide protection in high-g decelerations would be to have the feet on the floor with the back and the head pressed against the seat back and headrest. This is also
19、seen in Figure 1. These features shall be provided in all passenger safety information materials and briefings (reference ARP1384).SAE ARP4771 - 3 -3.2.3 Sideward Facing No consensus has been reached as to the best brace position occupants should assume in side-facing seats. It is not clear whether
20、a lap-belt/upper torso restraint provides more or less protection than simply a lap belt restraint. Therefore, no recommendation as to whether the passenger should be bent over or seated upright in the brace position can be made at this time. 3.2.4 Inflatable Restraints Inflatable restraints may req
21、uire special actions. If so, they shall be described in all passenger safety information materialsand briefings (reference ARP1384).3.3 Child Restraint No consensus has been reached as to the best brace position for occupants holding children. Children shall be restrained in an approved restraint sy
22、stem (reference AS5276/1).FIGURE 1 - BRACE POSITIONS TO TAKE IN DIFFERENT SEATING LOCATIONS SAE ARP4771 - 4 -4.
