It is no secret that pilots take on a lot of responsibility - so they have to be protected from all threats.
Whether they are embarking on a long-haul flight or making a short trip, they are responsible for the safety of everyone onboard while the plane is in the air.
So it is important for working crew members to take breaks to rest and refuel, whenever necessary.
But you may not know that cockpit staff are banned from tucking into the same meal on several major airlines, and for good reason.
Included in the numerous regulations staff must follow to keep themselves and passengers safe, you'll find a strict rule that dictates what pilots and their first officers can eat.

And while those in the cockpit are mostly free to eat what they choose, they cannot pick the same meal as each other.
As flight attendants explained to Travlerz, these crew members are forbidden from sharing meals due to the risk of food poisoning.
The precaution means that if one person falls ill during the flight, there's someone on hand to operate the aircraft.
The rule dates back to the very early days of commercial aviation and continues to be used by a number of airlines today.
But that is not to say the crew always get meals provided - crew meals are normally for international hauls only, not domestic flights.
And it is common for crews to bring along their own snacks to enjoy throughout the journey.
Alongside these revelations, the flight attendant also shared a number of further regulations cabin crew must follow - some of which defy expectations.
For instance, despite popular belief, the crew member said not all airlines forbid flight attendants from dating passengers.
In fact, many big airlines do not have any such policy. Equally, the crew are allowed to date each other, and such pairings are said to be "quite common".
The crew member also revealed why staff insist cabin lights must be turned off during take-off and landing - and it is not to create a calming atmosphere.
Rather, it is an important safety precaution. Not only does dimming the lights help passengers' eyesight to adjust in case of an emergency, but it also make the evacuation signs more clearly visible, should they be needed.
