You are preparing for a borescope inspection of an LM2500 gas turbine engine. You are reviewing the correct geometric orientation nomenclature which includes which of the following?

Correct Answer: Option A — All references left, right, and radial are orientated as viewed from aft looking forward on the engine.

Standard LM2500 technical documentation dictates that all geometric orientation, including left, right, and radial references, is established by viewing the engine from the aft end looking forward. This consistent frame of reference is essential for accurately locating and documenting defects found during borescope inspections or other maintenance tasks.
