Whether it is SANCA or MFE, Navigraph sequence is, for instance, MFE->MISSI->FATOR->MISSI. In reality, it should be MFE->FATOR->MISSI, or if using SANCA, SANCA->MISSI->FATOR->MISSI.
Basically, approach is SANCE or MFE + FINAL. I can see, in real life, the path airplanes take. It is never as Navigraph has it – it would be a very difficult and dangerous approach.
