If you are emailing your CV in response to an ad, don't worry about the content of the CV.
The person sifting through multiple applications doesn't actually want to open up your CV and read through it, because that wastes time. All they are interested in initially is wether or not you meet the min requirements.
So in your email message text, refer to things that the employer is looking for. Example, total time, right to live and work in that employers country, jet/turbo prop experience, type rating etc. etc.
They can then just glance at your message, determine if your a keeper or not and then move on to the next person in the list.
The next part of the process, once they've sorted the chaff from the hay, is to then open up CV's to read the details.
