If you are starting an ATPL course, and have no idea what an INS system is, you need MUCH more than you can get here. Find a good book or 3 about modern INS and FMS and other navigation systems.

Just a follow on to what Intruder has suggested: I recommend Global Navigation For Pilots (ISBN-13: 978-1560273127) by Dale De Remer as a good start to your study of navigation concepts. I read the first edition of this book long ago and it really helped me form a solid basis for future learning. And it contributed to piquing my interest in the subjects of maps and navigation to such a degree that I'm still interested in learning more!

Just do a quick search and you'll find this book online. There are several other books available on related subject areas as well...

Thanks for your suggestions to . Is those concept necessary for flying Cessna 172, cause now I'm just only student pilot

When I answered your question as it appeared in the original post, it was with the understanding that you were studying for ATPL exams. You would definitely benefit from understanding the concepts covered in Dr. De Remer's book if pursuing a professional pilot career. Someone working on their PPL should understand about charts at a basic level, but understanding advanced navigational concepts and equipment can wait until the more basic studies and skills building has been achieved. No, such studies are not strictly necessary to fly a 172 under visual flight rules. First things first!

I can suggest a couple of free to download tutorials from the FAA.gov website: The Pilots Handbook of Aeronautical Knowledge. (PHAK) and the Airplane Flying Handbook. Both contain allot of information pertinent to the student pilot as they progress through training.

Be safe, have fun and learn from every experience!

Best of success in your studies and your flying. Learn to crawl before you learn to walk. Learning to run comes later.

No, you don't need to know anything about IRS, INS, or any other navigation equipment, to fly a C172.

If he is in the U.S. and tries to make a fraudulent tax deduction for his 172 then, indeed, he needs to know about the IRS. :)

Last one I knew that got caught on that had a 310...

@firstch

To answer your OP (in very basic terms):

An Inertial Reference System, IRS, works by you telling it what Latitude and Longitude your aircraft is in the world before starting engines and moving. Then a very accurate system of gyros (either mechanical or laser ring) register any subsequent movement of the aircraft, which the IRS uses to calculate an instantaneous readout of your current latitude and longitude.

An Inertial Navigation System, INS, uses IRS information and the required route you programmed into the flight management system to guide the aircraft.

Modern FMGS use IRS, INS, ground based navigational beacons, and GPS satellite constellations to calculate aircraft position very accurately, sufficient to make an approach to land though cloud with low cloudbase.

The lowest cloudbase and poorest visibility approaches currently available are still obtained from ILS (Instrument Landing System - an integrated system of three ground based transmitters).

You will most likely navigate your Cessna 172 with your eyes looking outside, and by looking inside the cockpit at ground based navigation beacon receivers such as NDB, VOR, DME and perhaps ILS.

If he attends a modern flight training school, he will have that and then some in the current iteration of the Cessna 172; glass, GPS RNAV, ILS, and VOR.

I am somewhat surprised that no-one has suggested that most valuable publication entitled 'INERTIAL GUIDANCE SYSTEM SIMPLIFIED'
In brief therefore and published at no cost...
Inertial Guidance Systems Explained
