Please take a moment and update your account profile. If you have an updated account profile with basic information on why you are on Air Warriors it will help other people respond to your posts. How do you update your profile you ask?
When writing the personal statement, how specific should you be when talking about what option you want to apply for? Should I only mention that I want to be a pilot or should I also mention that I want to fly helicopters?
IMPO you should just keep it general and taylor it towards being a pilot. Your STA-21 personal statement has absolutely nothing to do with the platform you select out of Primary. You also dont want to risk the selection board being filled with pilots from all other communities and your statement somehow swaying their decision.
