If it has been fixed then it must be much longer. In this movie there were missing essential things:
- no APU operation- the APU needs to be started, then left running for at least 1 min to get optimal temperature, then both engines start-up with 1 min cooling pause between them and finaly 1 min cooling before shut it down;
- unrealistic main engines operation- in this movie you start both engines simultaneously which is absolutely impossible IRL. Then you turn on AC generators while at idle power-errrrrr! In order to have generators online rotor RPM must be above 85% which means AUTO mode for both engines.
- unrealistic elecrical system operation- no rectifiers on, inverters must be in manual before having generators on and after that you switch inverters to AUTO; later when you shut engines down everything is reverse- rectifiers off, inverters to MANUAL, generators off, engines control levers from AUTO to IDLE;
