The operations manual takes precedence
Airlines operate to rules approved by their home regulator. Many foreign regulations are disregarded by Qantas for example, because CASA is viewed by foreign regulators as a competent authority, able to make reasonable restrictions on the operations of their carriers. Its reciprocal...we don't require overseas carriers to comply with every bit of trivia in our AIP either.
And BTW, +1 on four engined ops. Zero panic. Otherwise explain the DC-10
A probably false story doing the rounds thirty years ago had a B-52 declaring a mayday after an engine failure. A calmer voice transmitted "Ah yes, the dreaded seven engine approach!"
