Padi Rdp Table Metric Pdf

PADI Recreational Dive Planner (RDP) (Metric version) is a specialized decompression table designed specifically for no-stop recreational diving. Unlike older tables like the US Navy versions, the PADI RDP was developed by Diving Science and Technology (DSAT) to better account for the nitrogen absorption patterns seen in multiple, repetitive dives.

Step 5: The Second Dive (Repetitive Dive)

You now plan a dive to 18 meters.

  1. You are now PG D.
  2. Go to the "Repetitive Dive" table. Find the column for 18m.
  3. Trace down to row PG D. It gives you your Residual Nitrogen Time (RNT) , e.g., 20 minutes.
  4. You want to dive for 25 minutes (your desired "Actual" Bottom Time).
  5. Total Bottom Time = RNT (20) + Actual (25) = 45 minutes.
  6. Check the NDL for 18m (56 minutes). 45 is less than 56. You are safe.

On the way up, her safety stop at 5 meters, she felt it anyway – a faint, itchy ache in her right shoulder. Psychosomatic, probably. But as she broke surface and Leo gave her a confused thumbs-up, she held up the clingy PDF. PADI Recreational Dive Planner (RDP) (Metric version) is

Round Up Only: If your exact depth or time is not listed, always use the next higher (deeper or longer) value. You are now PG D

2. Target Audience

  • Student Divers: Individuals taking their Open Water or Enriched Air courses who need to learn how to use the RDP.
  • Dive Professionals: Instructors needing a clean, digital version for teaching slides or printing handouts.
  • Recreational Divers: Divers who prefer carrying a digital backup of their dive planning tools on their phones.

3. How to Use the RDP Table Metric (Step by Step)

Step 1 – Plan the First Dive

  • Choose a depth (e.g., 18m) and find the maximum allowed bottom time (no‑decompression limit – NDL). For 18m, NDL = 56 minutes.
  • After the actual dive, find the actual bottom time (e.g., 30 min) in Table 1 → get Letter Group = M.
