You are preparing for a borescope inspection of a GE 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 GE LM2500 technical documentation defines engine orientation by viewing the unit from the aft end looking forward toward the intake. This convention ensures consistency for borescope inspections, maintenance, and component replacement, preventing errors in identifying specific stages or quadrants during critical engine internal assessments.
