As I said above, I am unsure what your qualifications are equal to but :
If you want to fly in the RAF - YES you will need A-Levels .
If you want to fly commercial - Read quote from OAT website
Applicants for the APP First Officer course must be 17 years of age to attend the Skills Assesment. They must have a minimum of five GCSEs at grade C or above and these must include English language, mathematics and either physics or double science. Overseas applicants must have the equivalent of the above or higher. A-levels are not required; however, many airlines give hiring preference to those who have A-levels or otherwise meet university entrance requirements. Neither OAA nor any of the airlines require applicants to have university degrees.
Good Luck
