16) How To Teach The RDP Flashcards
Your job as an instructor is to connect RDP use to made up scenarios? T/F
False - to actual diving circumstances
The Recreational Dive Planner (RDP) was designed for no- ____ recreational diving and was the first table specifically designed for this type of diving.
Stop
RDP introduced in 1988 and distributed by PADI? T/F
True
The RDP has more/less conservative no decompression limits (NDLs) than the Navy tables?
The RDP allows for longer/shorter repetitive dives because overall ______ absorption is kept higher/lower
More
Longer, Nitrogen, lower
Main feature/benefit of eRDPml?
A) it’s easier than the RDP
B) allows for multilevel planning
C) eliminates calculations required to figure out profiles using a dive table
B and C
When using the RDP is bottom time the total time of dive?
No, it starts at descent and continues until the diver leaves the bottom for ascent (safety stop time not included)
When using the RDP, any dive to 10 meters/35 feet or less is calculated at their depth rounded up to the nearest tenth? T/F
False just use 10m/35’
When using the RDP you can use the exact depth or if it’s not shown round down? T/F
False, round up if exact depth not shown
All ascents should be made no faster than ____ feet per minute.
60
It’s okay to push the RDP or dive computer to the maximum? T/F
False - be conservative and avoid maximum limits
When planning a dive using the RDP or eRDP for a cold water or strenuous dive assume the depth is 4m/10’ deeper? T/F
True
Plan repetitive/multilevel dives so each successive dive/level is shallower, limit them to 30m/100’? T/F
True
Never exceed 40m/130’; open water divers limit is _______; and with greater training and experience 30m/100’.
18m/60’
Is a safety stop always recommended? Y/N
When is one required and for how long at what depth?
Yes
Any dive to 30m/100’ or greater safety stop for 3 minutes at 5m/15’ and anytime you surface within 3 pressure groups of the NDL
What are the special WXYZ rules for multiple 3 or more dives in a day?
A) mandatory surface interval of minimum of 1 hour between all subsequent dives if end W or X
B) mandatory 3 hour surface interval between all subsequent dives after any dive ending in Y or Z
C) rules for dive profiles placing divers in a high pressure group close to the limit to keep residual nitrogen within the mode limits
All of the above
If accidentally go below 40m/130’ you should ascend no faster than 18m/60’ per minute to 5m/15’ and make an emergency deco stop for 8 minutes and any surface interval of 6 hours of dive again? T/F
True
If NDL is exceeded by less then _____ minutes then then _____ minute emergency deco stop at 5m/15’ is mandatory and must wait 6 hours before diving again.
If NDL is more than _____ minutes must do emergency deck stop for _____ minutes at 5m/15’ and no diving or flying for 24 hours.
5 minutes
8 minute emergency deco stop
5 minutes
15 minute emergency deco stop
Divers should limit repetitive dives to ____ dives per day?
3
If dive computers are readily available you’ll still teach new divers how to use them in addition to RDP and the eRDP? T/F
False - you’ll likely teach how to use dive computers but may also only teach RDP OR the eRDP as a backup
Divemasters only need to know the RDP or eRDP like new divers? T/F
False - they need to know both
When teaching any RDP you should:
A) use a giant table or projection to demo each step clearly
B) have students practice and complete each sample dive profile
C) use realistic profiles for student divers
D) use deep profiles
E) Don’t use profiles from their open water training dives
F) encourage self study before class
A, B, C, and F
What is the ANDL stand for
Adjusted No Decompression Limit
Altitude dives take place at 300-3000m or 1,000’ to 10,000’? T/F
True
At altitude pressure is greater or less than the 1 ATM at sea lever
Less
To use the RDP for altitude diving you must:
A) ascend at a rate of 9m/30’ per minute
B) 3 minute safety stop on all dives at depth prescribed on theoretical depth at altitude table
C) no more than 2 dives a day
D) if changing altitudes do first dive at higher altitude
E) if at altitude for less than 6 hours after arriving from a lower altitude you must account for the excess nitrogen by determining pressure group letter: count 2 groups for each 300m/1000’ (round up) then can allow for surface interval to reduce group
F) if diving above 2400m/8000’ wait six hours
G) actual depths must be converted to theoretical depths (round up) use Theoretical Depth at Altitude Table
H) some computers don’t adjust to the altitude automatically and therefore are adjusted manually unless not able to then it’s just a depth gauge and timer to use with RDP
All
If have a dive computer maintaining a record of the dive profile may allow diver to continue diving using the RDP if computer fails? T/F
True
You must dive within limits of RDP, not computer? T/F
False - divers may dive within limits allowed by the computer provided all dives are planned as no deco dives
Depth limit follows individual course standards and never exceeds ______
40m/130’
If a diver doesn’t have a computer he/she can just share? T/F
False they just use the RDP
If divers can’t adjust their computer for altitude or enriched air then diver uses RDP or theoretical depth at altitude table. T/F
True
All open water diver course students must plan dives using the RDP, even if they dive with computers? T/F
False
