Did you know that nowadays (at least in lufthansa) there can’t be only one human in th cockpit? I spoke to a pilot in lufthansa today and he told me that before the Germanwings accident it was still allowed to have only one pilot in the cockpit at one time. After the accident though, lufthansa immediately changed their procedures.
Now when pilots go to the toilet they firstly have to call the head steward, get him or her into the cockpit, let the pilot walk out and once the pilot gets back into the cockpit the steward gets out.
I know this is a pretty basic fact and easily understandable but I am really surprised that the procedure was only put in place after the accident with the Germanwings.
What are your thoughts on this? Is there any more convenient way to do it?
