This report covers an analytical study to determine the optimum location on a 727-100 airplane for positioning a discovered explosive device. The study consisted of (1) A review of existing methods for predicting blast effects on typical aircraft structure, (2) Selecting candidate locations for analysis, (3) Determining minimum and maximum hole sizes resulting from detonation of a given amount of explosive at the candiate locations, (4) Determining the aircraft’s capability for continued safe flight with minimum and maximum holes at the candidate locations, (5) Developing procedures which would provide the best chance of a safe landing in the event of detonation. The study concludes that a location adjacent to the mid-gallery door would be the optimum location, that the aircraft would survive with the minimum hole size at any of the thre locations and that the maximum hole size would be catastrophic at all but the mid gallery door location where, under conditions of limited air speed and gust velocity, continued flight and landing could be effected.

A literature search was conducted to summarize the results of previous work performed in establishing criteria for continuing the development of an instrument system which will aid pilots in making critical decisions during takeoff and landing rolls. The search revealed that many national and international studies had been made during the past 15 years, but interest diminished after 1963.

It appears that much talent and work were applied for creating a monitor but no acceptable units were produced. Additional research and evaluation is considered necessary.

Ten certified pilots were given time-sharing training using a low-cost visual in-cockpit device. Training sessions in a ground trainer with subsequent flight checks in an airplane showed marked improvement in cockpit/outside visual scanning and piloting proficiency. Pilots expressed favorable comments regarding use of the concept for student pilot training. Three pilot training schools also evaluated an in-cockpit aural signal device designed to prompt pilots to scan outside for other aircraft. The device received unfavorable comments from student pilots and flight instructors due to excessive amounts of annoyance and distraction, and was not recommended as a training aid.

The objective of this study was to evaluate the feasibility of containing or restricting in-flight or postcrash helicopter fires to allow the crew and passengers to escape or remain within a livable environment until the fire could be extinguished or the burning fuel consumed.
