You may think you know a lot about aircrafts, especially if you’re a frequent flier, but there are a few hidden features that may surprise you. While some of these attributes are meant to be out-of-sight and out-of-mind, these features can be the difference between making your entire flight experience comfortable or uncomfortable. The next time you board a flight; you may want to pay closer attention. Here are 10 aircraft features you likely never knew about.

The ‘I Need Space’ Button 

As airlines continue to cram in more seats and shrink legroom, you’ll continue to wish that you had more space. Luckily, there’s a small hidden button underneath your armrest that can give you that extra room you've been craving. Albeit, providing just a few more millimeters to move your hips, but it definitely helps.

The Secret Bedroom 

 Ever wondered where the cabin crew goes to get some much-needed rest on a long haul flight? Well, the secret bedroom definitely comes in handy. This compartment allows flight attendants and pilots to take naps, read books, or simply hide away from any nagging passengers. Because let's be honest, there are plenty of those.

The Little Black Triangle 

You may not have noticed it before, but somewhere inside the aircraft is a little black triangle marking the best passenger window. This window isn’t the deemed the best because it gives gorgeous views above the cloud — but it does give the best view of the aircraft’s wing. In case of an emergency on the wing, flight attendants will know exactly where to look because x marks the spot.

The Hidden Bathroom Latch 

If you think you can hide in the bathroom for hours and not get caught, think again. Bathroom doors have a hidden latch on the outside located near the “no smoking” sign, making it easy for flight attendants to unlock the bathroom in case of any emergencies. 

The Nifty Handrail 

If you tend to grab the headrest in front of you when standing up from your seat, you’re likely bothering nearby passengers. There’s actually a nifty trick to making standing up a little more steady and comfortable for everyone. Use the handrail located on the overhead bins and you’ll be standing up like a champ.

The Panel Full of Chemicals 

If oxygen masks ever need to be deployed, you’ll be getting it from a cocktail of chemicals. As oxygen tanks are too heavy for aircrafts, a sophisticated system is used instead to provide the much-needed air. A combination of chemicals, including barium peroxide, sodium chlorate, and potassium chlorate, is able to release oxygen when burned, thus making it easy to be carried on aircrafts. 

The Neglected Ashtrays 

Although smoking has been banned on aircrafts for many years, you can still find ashtrays on newly designed aircrafts. Continuing to have ashtrays is actually a safety precaution, in case some passenger decides to neglect the rules and have a smoke. Even though these ashtrays are neglected, they still are a mandatory requirement for aircrafts. 

The Exit Grab Handles 

Next time you board a plane, look for handles on the exit doors. If there ever is an emergency evacuation, these handles are very handy for flight attendants. As they are responsible for making sure every passenger exits the aircraft, the flight attendants can hold onto these handles ensuring that they do not get pushed and shoved as everyone makes their way to safety.  

The Staff Gas Masks 

If there’s ever a fire on your aircraft, the flight crew will receive their own gas masks. While passengers do not receive them, it is essential that the airline staff do because they are responsible for helping to put out the fire. 

The Handcuffs and Defibrillators 

Many different problems can occur in-flight and aircrafts do their best to be well prepared. If you ever wondered what would happen if an aggressive passenger became too unruly, rest assured knowing aircrafts have plastic handcuffs on board. Additionally, if a passenger were to have heart problems mid-flight, a defibrillator will be used.
