What does the acronym RDP stand for in PADI dive planning?
Answer: Recreational Dive Planner
RDP stands for Recreational Dive Planner, the tool PADI uses to plan no-decompression dives.
On the PADI RDP table, what does the letter group at the end of a dive represent?
Answer: The diver's residual nitrogen level
The letter group indicates the diver's residual nitrogen level after a dive, used to plan repetitive dives.
What is the minimum surface interval a diver must observe before flying after recreational diving according to PADI guidelines?
Answer: 12 hours
PADI recommends a minimum surface interval of 12 hours before flying after recreational diving.
Which PADI planning tool replaced the traditional paper RDP tables with an electronic format?
Answer: eRDPml
The eRDPml (electronic Recreational Dive Planner with multi-level capability) is the electronic version of the PADI dive planning tables.
When planning a repetitive dive using the RDP, what must a diver calculate before determining the new no-decompression limit?
Answer: Residual Nitrogen Time (RNT)
Residual Nitrogen Time (RNT) accounts for leftover nitrogen from the previous dive and must be added to actual bottom time.
What is the purpose of the 'safety stop' recommended by PADI during ascent?
Answer: To reduce residual nitrogen and lower DCS risk
A safety stop at 15 feet (5 meters) for 3 minutes allows off-gassing of nitrogen, reducing the risk of decompression sickness.
