What’s there under the bonnets of an aircraft and an automobile?

I boarded my flight from New Delhi to Ranchi. My boarding pass showed seat no. 1C. It was the first row.

I stowed my luggage and sat down.

It was an early morning flight. I prepared to settle down and looked all around me to check on how the morning activities were gathering pace at the airport.

Through my right side window seat, I saw another aircraft parked. And I saw an attendant wiping clean its nose cone as shown in the featured picture above.

I wondered why he was wiping it?

And then, I realized that the nose cone of an aircraft holds the radar system inside it. Probably the attendant was wiping clean all the dust, water droplets (or moisture) and foreign matter so that the radar waves doesn’t get deflected and give faulty information while searching for moisture in the clouds during the flight and showing the output to the pilots in the cockpit on their radar screen.

The picture below shows what you will find if you open the cone. A weather radar system!

Let us dig a little more on the weather radar system.

The picture below shows an aircraft’s cockpit and the weather radar system at the centre of it.

The red dots on the computer screen (based on the inputs received from the weather radar system) shows that there is moisture or a hailstorm building among the clouds ahead or in plain language there is a turbulence on the route. The pilot decides (of course, this also depends on his/her flying experience, built over all those years) the course of the flight based on this screen display for the areas which he/she should avoid for a smooth and turbulence free flight.

Further, a Weather Radar System (WRS) is also known as Doppler Radar System (DRS).
