PADI Recreational Dive Planner (RDP) 3

Question 1

What is the maximum depth limit for recreational dives planned using the PADI RDP?

Accepted Answer

130 feet / 40 meters

Answer

The PADI RDP is designed for recreational dives to a maximum of 130 feet (40 meters).

Question 2

When planning a dive to 70 feet, which RDP depth column should you use if 70 feet is not listed?

Accepted Answer

The next deeper depth column

Answer

When your planned depth falls between listed depths, always use the next deeper depth column to plan conservatively.

Question 3

A diver plans a repetitive dive to 50 feet and finds an RNT of 47 minutes with an NDL of 100 minutes. What is the maximum Actual Bottom Time (ABT) for this dive?

Accepted Answer

53 minutes

Answer

Maximum ABT = NDL minus RNT, so 100 − 47 = 53 minutes.

Question 4

Which of the following best describes a 'no-decompression limit' (NDL) as shown in Table 1 of the RDP?

Accepted Answer

The maximum time at a given depth before mandatory decompression stops are required

Answer

The NDL is the maximum bottom time at a given depth that keeps a diver within the no-decompression range.

Question 5

Why does the RDP use the deepest depth reached during a dive for planning purposes, even if most of the dive was shallower?

Accepted Answer

Because nitrogen absorption is greatest at the deepest point, and planning for worst-case protects the diver

Answer

Nitrogen dissolves into tissues faster at greater pressure, so the RDP uses the deepest point as a conservative planning baseline.
