PADI - Professional Association of Diving Instructors Dive Planning and Management Questions and Answers

Question 1

A diver is planning a dive on a reef with a single entry/exit point. To ensure an adequate air reserve for the return journey and any potential contingencies, what is the most widely accepted and conservative rule for managing gas supply?

Accepted Answer

Use one-third of the starting pressure for the outbound journey, one-third for the return, and keep one-third in reserve.

Answer

The 'rule of thirds' is a standard, conservative gas management principle for dives where the exit point is the same as the entry. It allocates one-third of the gas for the journey out, one-third for the journey back, and leaves a final third as a safety reserve for unexpected delays, emergencies, or assisting a buddy.

Question 2

You are planning a dive at a site known for a consistent, moderate current where you will enter and exit at the same point. What is the generally recommended dive plan to manage effort and gas consumption effectively?

Accepted Answer

Begin the dive by swimming into the current, and use the current's assistance for the return trip.

Answer

The standard procedure for a current dive from a fixed point is to swim into the current at the beginning of the dive when you are strongest and have the most gas. The return trip will then be easier as it is assisted by the current, which is especially important if you are low on gas or energy.

Question 3

During a dive, your primary dive computer malfunctions and the screen goes blank. Your buddy's computer is functioning correctly. What is the safest and most appropriate course of action?

Accepted Answer

Immediately and safely terminate the dive with your buddy, performing a safety stop on ascent.

Answer

The failure of your primary means of monitoring depth, time, and decompression status is a significant safety issue that requires ending the dive. The safest and most prudent action is to abort the dive with your buddy, using their computer to monitor a safe ascent and safety stop.

Question 4

As a dive leader conducting a pre-dive briefing, which of the following elements is MOST critical to include to ensure the team has a shared understanding of the dive plan and safety procedures?

Accepted Answer

A review of the dive objective, planned route, depth/time limits, turn pressure, and emergency procedures like buddy separation.

Answer

The primary purpose of a pre-dive briefing is to ensure safety and coordination. It must clearly outline the dive plan (objective, route, limits) and emergency procedures (like what to do if buddies get separated) so every diver knows what to expect and how to react, creating a shared understanding for the entire team.

Question 5

When formulating a comprehensive emergency assistance plan for a new or remote dive location, which of the following components is MOST essential to research and have readily available?

Accepted Answer

Contact information for the nearest medical facility, recompression chamber, and local emergency services (e.g., DAN, coast guard).

Answer

An emergency assistance plan's primary function is to ensure a rapid and effective response to a diving accident. This requires having immediate access to contact information for local emergency medical services, as well as specialized facilities like a recompression chamber and diver-specific hotlines like the Divers Alert Network (DAN).
