With a PPL you learn basic flying skills aircraft handling navigation weather awareness flight safety and emergency procedures. These skills build your confidence and give you first hand experience in piloting an aircraft something that is essential for any pilot career.
Because PPL is recognized under aviation rules it qualifies you to later apply for a Commercial Pilot License (CPL). A CPL is needed if you want to work as a paid pilot in airlines charter services or other commercial aviation jobs. Thus PPL acts like a stepping stone. It lets you get comfortable with flying before you commit to heavier training and investment for CPL. Many pilots start with PPL to test their interest and aptitude.
Even if you don't immediately pursue CPL having PPL gives you option to fly privately for personal travel or leisure. For students unsure if they want airlines level commitment PPL offers a way to enjoy flying learn discipline improve decision making under pressure and understand aircraft operation. These soft and hard skills remain useful throughout a pilot's career.
You also get early exposure to aviation environment you understand cockpit procedures air traffic communication aircraft checks flight planning so when you eventually go for CPL you are not a complete beginner.
However PPL by itself does not allow you to fly for pay. That means you won't earn pilot salary in India with just PPL. For real income (salary allowances career growth) you must upgrade to CPL and then ideally build hours for airline jobs. Also job opportunities with only PPL are limited. Most airlines and charter companies demand CPL or higher.
If you dream of becoming a pilot PPL gives you the right base practical flying skills familiarity with aircraft and confidence without immediately committing to full commercial training cost and workload. Later you can build on it.
