Question 54Gas Turbine - Assistant Engineer

The correct answer is D) All of the above. For a normal start of a GE LM2500 gas turbine engine, the following permissives must be met: 1. The bleed air valve must be closed to ensure proper engine start-up. 2. The GG (gas generator) speed must be less than 1200 RPM, and all engine trips must be reset to allow the engine to start safely. 3. The fuel supply pressure must be greater than 8 psig to provide the necessary fuel flow for the engine to start and operate correctly. The other options are incorrect because they only address a subset of the required permissives. All three conditions must be met to ensure a normal and safe start of the GE LM2500 gas turbine engine.
