Question
9. Figure 8.32 shows the altitude of an aircraft that encountered a microburst and crashed as a result, as a function of time before the crash (in seconds). During what period of time was the aircraft experiencing a headwind? During what period of time was the aircraft experiencing a tailwind? During what period of time did the aircraft pass directly beneath the microburst? Explain your answers. Figure 8.32. Laboratory Exercise 9 Aircraft altitude as it encountered a microburst prior to crashing short of a runway. Time is in seconds before the crash. 1000 750 9 250- 30 20 10 Time Before Crash (seconds)Explanation / Answer
Tail wind is from 20 to 14 seconds before crash as the Elevation above ground level increases.
Head wind is from 30 to 20 seconds before crash as the Elevation above ground level decreases.
And from 14 to 8 seconds before crash, the aircraft passes directly beneath the microburst as the Elevation above ground level is constant that time.
