They're not just random design

People are only just discovering why planes have 'strange whiskers' on their noses.
From the meaning of 'i' in iPhone to the purpose of black dots on train windows, there are everyday features we take for granted until the dutiful internet explains their purpose.
Have you ever noticed those thin metal probes poking out from the front of a plane?
While they look like whiskers on an animal's face, they're actually some of the most vital sensors of the entire aircraft.

They're called pitot tubes and, without them, modern planes wouldn’t be able to fly safely.
They measure airspeed by comparing the pressure of oncoming airflow against static air pressure. They then send that information straight to the flight computers, which they can use to make calculations for the journey.
In fact, the entire flight depends on it.
Modern aircraft rely on precise airspeed readings to maintain the delicate balance between efficient flight and aerodynamic safety.
Without them, pilots would have no reliable way to know if they're going too fast, too slow, or getting dangerously close to a stall.
According to an observant Reddit user, Airbus actually explains the different types of sensors that the aircraft has.
"MFP is Multi-Function Probe, which uses multiple pressure readings to return data that the other probes also return (angle of attack, airspeed, etc)," they wrote. "AOA is Angle of Attack, it's used to report the pitch of the aircraft relative to the airflow."
Meanwhile, the Total Air Temperature (TAT) reportedly helps calculate an accurate airspeed.
But these probes are only part of the story.
Right between them sits something called the radome, which is the rounded nose cone that covers the aircraft’s weather radar.
The radar fires out radio waves ahead of the plane. When the waves bounce off water droplets, they create a map of storms and turbulence before anyone in the cabin spots a single cloud.
Adding to this, modern radars incorporate Doppler processing, which allows for even more detail.
This means the system can distinguish between harmless rain and the kind of serious turbulence that'll have your drinks flying everywhere in the cabin.
Pilots use these radar scans to request route changes, climbs to different altitudes, or delays, all to keep your flight as smooth and safe as possible.
