Accident, incident and crash related photos, Air to Air A centrifugal pump has the following dimensions: d2 = 42 cm, L = 5 cm, and $\beta 2=33^{\circ}$. A bit out of topic, but since the 757 and 737 have the same fuselage width, do they share any similar parts? This is for guidance only; any enforcement should be determined by the circumstances found on site. In the longer term we should be asking companies to come up with a programme and timetable for replacement or improvement of equipment where necessary. Flying higher means that commercial airplanes can avoid most other airborne traffic. Passing through an aircraft door represents the start or end of one's time onboard an aircraft. In such cases, safety equipment must be used and certain precautions followed. When removing the battery is necessary, carriers must remove and package the battery in carrier-provided packaging, if asked to do so by the passenger. Instead the precautions will be identified solely on the basis of an assessment of the risks involved. Why didn't they make the 757 wider. With his mittened hands, he cracked open the shells. Once the slide is completely free it will fall under gravity and after travelling a certain distance a pin will be pulled from a squib containing compressed gas and the slide will inflate. [5] Prior to inflatables, some passenger aircraft utilized canvas type slides which required the crew to undertake an extensive rigging procedure. AIRCRAFT MODEL: WINGSPAN: .
