Whether you plan to do FW flight nursing one day or RW, the requirements in terms of education and experience are the same. I'd highly recommend you read through all the other threads here in this specialty page as the answers to your questions posed, are all there and have been answered in previous posts ( I answered these questions several times myself).
On FW transports, these patients are not always stable. Many are critical care transfers so having extensive and varied experience in the critical care specialty is essential as you draw upon that when you are taking care of patients on your own , outside of the hospital environment. You shoulder the legal responsibility for care of these patients entirely as well, so remember that.
Most FW services that I know , expect their RN's to be on call and available for several days in a row with the ability to depart on a flight at a moments notice, so reliable childcare which you trust is essential.
You have a long way to go though so , don't worry about those issues as you have years ahead of you before you will need to even think about those matters. You need to get your BSN, then get into an ICU for at least 5 years , complete your CCRN as well as ACLS, PALS, NRP, TNATC courses before you will be eligible to apply for any flight nurse position. Enjoy the Now and being a nursing student; soak up all the experiences that you are exposed to and keep your mind open to the many areas of nursing that are out there and don't box yourself in to one specific super specialty at this stage of your life. Best of luck on your journey!
