The capability of a submersible vehicle to accurately maintain its commanded depth in a variety of operating speeds, depths and loading conditions is critical for mission accomplishment. Below a certain critical speed a phenomenon known as dive plane reversal occurs, where depth response changes sign with respect to a given dive plane command. This thesis builds on previous studies of the phenomenon and it presents a comprehensive sensitivity study of dive plane reversal envelopes in the presence of external forces and moments on the vehicle. Based on these results, rational design and operational decisions can be made in order to avoid unpredictable vehicle response.
