Two in cockpit rule
 

After the Germanwings crash of 9525, I only fly with airlines that employ the 2 person cockpit rule.

Now I want to go from Germany to Singapore and find an airline that still adheres to that rule after many airlines in Europe abolished it in 2017.

Could you please suggest me an airline where you witnessed replacing or know that a crew member replaces the pilot when they go to the toilet?

How about Turkish Airlines, Cathay Pacific, Etihad or Singapore Airlines?

It would help me so much because I don’t know if I can take my flight without knowing that.

Best Regards

Hate to tell you this but any two person in the cockpit rule is a false sense of security against a pilot who wants to take nefarious action because there are still items onboard the aircraft, such as a fire extinguisher or crash axe, that can be used as weapons to injure and incapacitate the other pilot or the other person in the cockpit while behind the locked door. The pilot could also put in a violent control input as soon as the other pilot vacates the seat but before the other person actually comes into the cockpit, causing injury to the pilot (and to the FA waiting to come in).

The rule was abolished because it didn’t accomplish anything, apart from a fleeting moment of a regulator being seen to be doing something.

Looks like you’ll be staying in Germany ....

All US airlines must comply with the two-person rule. I don't know which non-US airlines do as well.

This may be regarded as sensitive security information and you won’t find a list of airlines that have or don’t have this rule. That said, you’ll be perfectly safe on any airline, 2 person or not. Looking for airlines for this rule is very irrational.

The rule isn't just to prevent a solo pilot from going rogue. There's also the issue of medical emergencies. Cockpit doors were reinforced after 9/11, and that created a new risk of a solo pilot having a medical emergency and the other pilot not being able to get back into the cockpit to help. Considering that all US carriers manage to comply with this rule, and that it doesn't really cost anything to implement, it's a bit puzzling as to why it's not universally done.

Bit OT but I must have been hawked and tuahed now as I read the title as ”two in cockspit” :D

Agreed. I also don't accept the argument that having a second person wouldn't be effective to deter a rogue pilot who wanted to crash the plane. Sure, one pilot could overwhelm the other one by force, or the two could be in it together, but that's less likely. Having a second person in the cockpit is something of a deterrent.
