CTC Aviation & FTE Jerez use the PILAPT test, whereas OAA & EPST use the COMPASS test.
I believe the GAPAN Aptitude Tests are actually the same test as used to assess candidates for the RAF Officer & Aircrew Selection Centre at Cranwell and therefore would not prevent you from taking the other types of tests listed above.
However, best practice would be to get in touch with someone at GAPAN to clarify this.
