It is scary enough being a plane passenger in poor weather conditions, so it must take an extra dose of bravery and confidence to be a pilot when the weather is less than favourable.

In low visibility, a pilot is heavily dependent on the plane's instruments, autopilot and the instructions of air traffic control. Sometimes, the runway will not even be visible until the final moments of the descent.

That is the case in this fascinating video, which is understandably going viral today.

Next time you are in a plane in rain or fog, you might just have that extra bit of appreciation for the pilot, airport staff and even the technology that gets you to the ground safely.
