CBSE 12th

If you are aspiring to be a pilot, then it will not be of any major use, because you will be flying in an environment where English will be majorly used for almost all the communication. Radio Telephony and ATC communications will require usually English and you may also communicate in French, but only when you fly in French airspace. Now, if you are aspiring to be a cabin crew, then French will be helpful, because cabin crew directly interact with the passengers and many passengers who are of French origin would not know English. So, communication with them would become easy and flawless, if you can speak in their language. This would enhance understanding them better and making their journey more comfortable.
