Navigational aid

A navigational aid is like a map or a guide that helps you find your way when you are travelling. It is like a friend who can help you reach your destination. Just like how your parents help you reach your school by holding your hand and showing you the way, a navigational aid helps pilots, captains and traveleers to see where they are going and make sure they reach the right place at the right time.

For example, when you drive a car, you use road signs to tell you where to turn, how far you should go and how fast you should drive. Similarly, a navigational aid helps pilots navigate their airplane by showing them where they are in the sky, how high they are flying, how fast they are going and where they need to go next.

Different navigational aids use different signals or signs to help travellers find their way. These include things like radio signals, GPS, maps, compasses and even stars. Navigational aids make travelling safer and easier by providing important information to the pilots or captains so they can steer their vehicle in the right direction.

So, just like how your parents hold your hand and guide you to your destination, a navigational aid helps travellers reach their destination safely and without getting lost.
