When performing cold-weather starts on the T-800 turbofan engine, the flight crew must adhere to a rigid initialization sequence. First, the crew must isolate the pneumatic manifold by verifying that the cross-bleed valve is closed. Next, the auxiliary power unit (APU) is engaged to provide electrical bus stabilization before introducing any aviation fuel. Once the APU reaches 95% of its maximum RPM, the igniter plugs must be energized continuously. The crew is required to monitor the exhaust gas temperature (EGT) meticulously; if the EGT exceeds 720°C during the first ten seconds of combustion, an immediate fuel cutoff is mandated. Notably, unlike standard warm-weather procedures, the pre-start lubricating oil pressure check is bypassed to prevent sensor cavitation in sub-zero conditions.
Is it true or false that, based on the provided text, the flight crew is NOT instructed to open the cross-bleed valve, perform a pre-start lubricating oil pressure check, or isolate the pneumatic manifold?
