WebbA sudden depressurization in the cabin will be a Mayday call, but a very small leak in the cabin leading to slow depressurization is a Pan-Pan call. No matter which call is declared the pilots can also use a device called a Transponder to help bring attention. Webb6 dec. 2024 · Hence, the system required a relatively slow depressurization rate (e.g. 0.08 MPa min −1) for a transition. At the low pressure region, because the mass transfer capacity of scCO 2 in the channels gradually weakened, the depressurization rate could be properly raised to shorten the synthesis time [ 14, 22, 28 ].
