Narrative:

On the jiboa departure from sal, the FMS commands a turn to moram prior to reaching the required 8000 ft that the departure procedure demands. We caught this and flew the departure properly. However, I recommend that a message be attached to all flts out of sal warning the crew of this potential pitfall. There is a 7159 ft mountain between the turn point and moram.
