RECOMMENDATIONS 3.1 Gene
17、ral Recommendations 3.1.1 Each floor-level passenger cabin emergency exit should have similar operating procedures to the other floor-level emergency exits on an aircraft.3.1.2 An exit with a door/hatch that is automatically stowed out of the egress path when opened is preferable to a removable hatc
18、h that must be manually stowed. 3.1.3 For each exit design, the ability to operate the exit shall be demonstrated with the evacuation system in both the Normal and Emergency Modes. This should be accomplished by using a test sample of at least five participants who are representative of those expect
19、ed to operate the exit, including a 5thpercentile female and a 95thpercentile male. Each test participant should open the exit from the inside with it in the Normal Mode and separately with it in the Emergency Mode. 3.1.4 Increasing cabin differential pressure should act to increase the security and
20、 retention of the exit door/hatch.

21、can be opened shall not create a hazard to the person opening the exit. 3.1.6 Means shall be provided to safeguard against inadvertent exit opening by passengers or crew during movement of the airplane on the ground or in flight. In addition, design precautions shall be taken to minimize the possibi
22、lity of a person intentionally opening the exit during flight, except where emergency procedures require in-flight opening of the exit (e.g., smoke evacuation). 3.1.7 The exit shall be fully openable in the Emergency Mode when the airplane is in adverse attitudes that correspond to the loss of one o
23、r more legs of landing gear. This should be demonstrated, using a 5thpercentile female, with the exit positioned in the worst-case attitude and taking into account the combined effects of the door/hatch weight, door/hatch motion and deployment of the evacuation assist means. 3.1.8 An exit equipped w
24、ith an emergency power assist system should be fully openable in the event of airplane power loss, while the airplane is positioned at its normal attitude (i.e., losing the power to an emergency power assisted exit shall not cause the exit to be unopenable). It should be demonstrated that a 50thperc
25、entile male can open the exit from inside the airplane without the benefit of the power assist system when the airplane is positioned at normal airplane attitude. 3.1.9 An exit designated as an entry or service door and equipped with an emergency power assist system and/or an evacuation assist means
26、 that can be automatically deployed when the exit is opened, shall be provided with a means inside the airplane, on or adjacent to the door/hatch, to allow opening of the exit without activation of these devices (i.e., the ability to arm/disarm the system). This exit shall also have a means to autom
27、atically prevent deployment of the assist means if the exit is opened from outside the airplane. The power assist system may activate if the exit is opened from the outside, provided it does not create a hazard to the person opening the exit. 3.1.9.1 An exit dedicated for emergency use only and equi
28、pped with an emergency power assist system and/or an evacuation assist means that is automatically deployed when the exit is opened, should be provided with a means inside the airplane, on or adjacent to the door/hatch, to allow opening of the exit without activation of these devices (i.e., the abil
29、ity to arm/disarm the system). For non-floor level exits, the means shall not be accessible to passengers. 3.1.9.2 Any potential hazards associated with opening an exit, which is dedicated for emergency use only, from the outside shall be identified in warning placards on the exterior of the exit (i
30、.e., automatic activation of a descent device and/or a door power assist system),3.1.9.3 The exit shall be openable in the event of ice buildup on the outside of the airplane. The ability to do so should be demonstrated by test. An acceptable test method is described in Transport Canada Advisory Cir
31、cular No. 500-003.3.1.9.4 The exit shall have a visual means that indicates when all required operations to close, latch, and lock the door have been completed. 3.1.9.5 The exit shall have a means to permit viewing of the conditions outside the airplane. If the outside viewing means cannot be positi
32、oned on the door, it may be located adjacent to the exit, provided there are no obstructions between it and the exit. The outside viewing means shall also permit viewing of the ground in the vicinity of where the evacuees would normally be expected to contact the ground when using the deployed evacu
33、ation assist means with the airplane in the normal attitude (all landing gear intact) and in the adverse attitudes corresponding to the loss of one or more legs of landing gear.

35、peration shall be obvious. The handle should be located on the door. If the handle cannot be located on the door, it should be positioned immediately adjacent to the door away from seated passengers.3.2.1.3 The entire operation of the handle shall be a smooth continuous motion, with no abrupt change
36、s in force or direction. Adequate hand clearance shall be provided throughout the handle travel, and the arc of handle rotation shall not exceed 180 degrees. 3.2.1.4 Secondary operations (e.g., removing covers, unlocking stops, straps, bars, or catches) shall not be necessary to open the exit in the
37、 emergency mode. 3.2.1.5 In the event that an exit is for some reason limited to partial opening, the handle should not further impede someones ability to use the exit. 3.2.1.6 The handle grip should be at least 10.2 cm (4 inches) wide, and the initial movement of the handle grip should be generally
38、 upwards. 3.2.1.7 The motion of the handle grip should provide the maximum mechanical advantage to assist in opening the exit. With the airplane in the normal attitude and subjected to the maximum normal allowable on-ground cabin pressure differential, the force required to operate the handle in the
39、 Emergency Mode should not exceed 222 newtons (50 pounds), and it shall be demonstrated that a 5thpercentile female can fully open the exit. 3.2.1.8 The range of motion of the handle grip, through its full travel, should be between 76 cm (30 inches) and 140 cm (55 inches) above the floor. 3.2.1.9 Th
40、e handle grip shall not be covered, hidden or obstructed by any cabin furnishings and shall contrast in color with the background and adjacent trim to enable locating the handle grip in emergency lighting conditions (see ARP503 for recommended emergency evacuation illumination levels). 3.2.1.10 The
41、interior handle shall automatically return to the closed position when the exit is closed from outside the airplane. When the exit is closed from the outside, movement of the interior handle shall not be hazarous to someone positioned inside of the airplane near the exit. 3.2.2 Opening Handle, Inter
42、ior, Non-Floor-Level Exits 3.2.2.1 The opening handle location and operation shall be obvious. The handle should be located on and positioned near the top of the door/hatch. The handle should be clearly visible and accessible, even if covered by a cover intended to preclude inadvertent opening by a
43、passenger.3.2.2.2 The handle grip should be at least 10.2 cm (4 inches) wide. 3.2.2.3 The motion of the handle grip shall provide the maximum mechanical advantage to assist in opening the exit. For removable hatches, the motion of the handle grip should facilitate the removal and handling of the hat
44、ch. With the airplane in the normal attitude and subjected to the maximum allowable on-ground cabin pressure differential, the force required to operate the handle in Emergency Mode should not exceed 222 newtons (50 pounds), and it shall be demonstrated that a 5thpercentile female can fully open the
45、 exit. 3.2.2.4 If the exit can be closed from the outside, the interior handle shall automatically return to the closed position when the exit is closed from outside the airplane.

47、d be between 76 cm (30 inches) and 140 cm (55 inches) above the exit sill. 3.2.3.2 The handle grip should be at least 12.7 cm (5 inches) wide. 3.2.3.3 Clearance shall be provided to allow gripping the exterior handle with gloved hands. 3.2.3.4 With the airplane in the normal attitude and subjected t
48、o the maximum allowable on-ground cabin pressure differential, the force required to operate the handle should not exceed 222 newtons (50 pounds) on each handle grip, if two handle grips are provided, or 334 newtons (75 pounds) if a single handle grip is provided. It shall be demonstrated that a 50t
49、hpercentile male can fully open the exit under these conditions. 3.2.3.5 The exterior handle shall automatically return to the closed and stowed position when the exit is closed from inside the airplane. When the exit is closed from the inside, movement of the exterior handle shall not be hazarous to someone positioned outside
