The answer to this question is both yes and no. Yes for those people who are not competent and lack behind the requirement it poses behind anyone aspiring to become a pilot and no to the people who have the passion to fly high and can ready to do anything to master the flying skills and thus take up the career with new vigour and spirit. The fact remains very clear and vivid, the career of pilot is not any usual nine to five job, which we all do in different offices based in any conventional market. It is very much demanding, which often would ask you to fly the aircrafts with utter professionalism and responsibility for long and even extended hours.
If you are into commercial flying then the airline companies do consider pilots who are skilled, committed and have clean track records than the ones, who are feeble, unprofessional and unproductive. After all, the job of flying in the air and taking countless passengers from one place to the other is really a difficult job to accomplish. Hence before you even think of joining the pilot training program, do keep in mind to check all the requirements of the job along with the attributes or skills you need to develop while going for the commercial flying. Do keep in mind that commercial flying and recreational/leisure flying are two different things. You cannot just mix them together and call the same to as one.
Also, whether the pilot training happens to be difficult or simple would also depend upon the institute you join for the training programs. Joining competent flying schools like Blue Bird Flight Academy can really make the learning simple and effective. This school has a competent staff with flying expertise and knowledge backed by years of experience in this sector. In addition, in terms of infrastructure and quality of fleet, this institute turns out to be very good. Hence, the flying school you join would also make the difference in your pilot training. In nutshell, if you have the passion of flying high and have the competence to do so, no one can stop you to join the career of commercial flying.
