70% to passWhich of the following instruments is designed to help you when performing an internal inspection of the gas turbine engine?
ATelescope
BStroboscope
COscilloscope
DBorescope
AI Explanation
The correct answer is D) Borescope. A borescope is a specialized instrument designed to inspect the internal components of machinery, such as gas turbine engines, without disassembling the entire unit. It consists of a long, flexible tube with a camera and light source at the end, allowing the operator to visually inspect hard-to-reach areas within the engine. This makes it an essential tool for performing internal inspections of gas turbine engines, as required by the US Coast Guard Captain's License Examination. The other options, such as a telescope, stroboscope, or oscilloscope, are not specifically designed for internal engine inspections and would not be the most appropriate choice for this task.
