Final answer:
When the BATT MASTER switch is turned on, integral lighting on certain panels should illuminate full bright and cannot be dimmed. However, the provided options do not represent the actual behavior caused by the BATT MASTER switch. The correct answer is 'g. none of the above', as integral panel lighting is typically dimmable in an aircraft.
Step-by-step explanation:
When the BATT MASTER switch is turned on, specific panels' integral lighting illuminates full bright and these lights cannot be dimmed. This function ensures that critical information is always visible to the crew, regardless of ambient light conditions. However, the options provided in the question:
a. APU panel
b. Electric panel
c. FIREX MONITOR/SPS test panel
d. Standby compass
e. ISI
f. All of the above
do not accurately relate to effects when the BATT MASTER switch is on. These choices do not correspond to the illumination behavior governed by the BATT MASTER switch and are not representative of the integral lighting system of an aircraft. Therefore, the correct answer from the provided choices would be ' g.none of the above'. Integral lighting on panels such as the APU, Electric, FIREX MONITOR/SPS test, Standby compass, and ISI would typically be part of an aircraft's dimmable cabin or cockpit lighting circuit, rather than permanently fixed at full brightness.
The correct question is: With the BATT MASTER switch on, the following panels' integral lighting illuminates full bright and cannot be dimmed:
a. APU panel
b.Electric panel
c.FIREX MONITOR/SPS test panel
d.Standby compass
e. ISI
f.All of the above
g. none of the above
