challenging (χ 2 = 2.89, p = 0.09, odds ratio 2.23, 90 per cent confidence intervals 1.01 to 4.91). Figure 60: Build challenge for fuel system Fuel systems did not generally present as much challenge as aircraft engines and airframes, using the quite challenging and very challenging ratings as a reference group. The descriptions of how fuel systems were modified in this report are not generally detailed enough to examine exactly what people found challenging. Avionics challenge Survey respondents found avionics quite a significant build challenge (Figure 61). About 30 per cent or 80 of 269 respondents found avionics to be quite challenging or very challenging, but the challenge appears to be independent of the type of instruments installed in the aircraft (χ 2 = 2.03, p = 0.36). Certain general skills are required to build an aircraft such as following plans; what Gardner (1983) calls visual-spatial intelligence. However, it appears that avionics challenges this intelligence in a special way. The most challenging part of installing avionics usually lies in integrating different components (Figure 62).

Figure 62: Example of an avionics wiring diagram Figure 62 incorporates an additional alternator and computer Hydraulics challenge Build challenge associated with hydraulics is found in Figure 63. There were 20 of 261 respondents who found hydraulics quite challenging or challenging. Four respondents had aircraft with retractable gear, one has dual hydraulics, three made modifications to wheels or brakes, and one had an amphibious aircraft. Four of the respondents who indicated that hydraulics were quite challenging or very challenging built more than one ABE aircraft. Figure 63: Build challenge for hydraulics Other build challenges The question relating to build challenge provided an open-ended other option and 20 respondents provided additional answers to the set options. Some of these answers related to building a component, and some to process or relationships - 69 -
