B737 Rapid Depessurisation headset or speakers on?
Question re use of headsets on during emergency descent after rapid depressurisation. My understanding is that the correct procedure for establishing communication once the oxy masks are on is to use the loud-speakers for comms between the pilots. On recent sim session the instructor required that headsets should be used over the masks. Is there a correct answer? Or is it left to the captain to decide the policy?
