16) How To Teach The RDP

Question 1

Your job as an instructor is to connect RDP use to made up scenarios? T/F

Answer 1

False - to actual diving circumstances

Question 2

The Recreational Dive Planner (RDP) was designed for no- ____ recreational diving and was the first table specifically designed for this type of diving.

Answer 2

Stop

Question 3

RDP introduced in 1988 and distributed by PADI? T/F

Answer 3

True

Question 4

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

Answer 4

More

Longer, Nitrogen, lower

Question 5

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

Answer 5

B and C

Question 6

When using the RDP is bottom time the total time of dive?

Answer 6

No, it starts at descent and continues until the diver leaves the bottom for ascent (safety stop time not included)

Question 7

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

Answer 7

False just use 10m/35’

Question 8

When using the RDP you can use the exact depth or if it’s not shown round down? T/F

Answer 8

False, round up if exact depth not shown

Question 9

All ascents should be made no faster than ____ feet per minute.

Answer 9

60

Question 10

It’s okay to push the RDP or dive computer to the maximum? T/F

Answer 10

False - be conservative and avoid maximum limits

Question 11

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

Answer 11

True

Question 12

Plan repetitive/multilevel dives so each successive dive/level is shallower, limit them to 30m/100’? T/F

Answer 12

True

Question 13

Never exceed 40m/130’; open water divers limit is _______; and with greater training and experience 30m/100’.

Answer 13

18m/60’

Question 14

Is a safety stop always recommended? Y/N

When is one required and for how long at what depth?

Answer 14

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

Question 15

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

Answer 15

All of the above

Question 16

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

Answer 16

True

Question 17

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.

Answer 17

5 minutes
8 minute emergency deco stop

5 minutes
15 minute emergency deco stop

Question 18

Divers should limit repetitive dives to ____ dives per day?

Answer 18

3

Question 19

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

Answer 19

False - you’ll likely teach how to use dive computers but may also only teach RDP OR the eRDP as a backup

Question 20

Divemasters only need to know the RDP or eRDP like new divers? T/F

Answer 20

False - they need to know both

Question 21

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

Answer 21

A, B, C, and F

Question 22

What is the ANDL stand for

Answer 22

Adjusted No Decompression Limit

Question 23

Altitude dives take place at 300-3000m or 1,000’ to 10,000’? T/F

Answer 23

True

Question 24

At altitude pressure is greater or less than the 1 ATM at sea lever

Answer 24

Less

Question 25

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

Answer 25

All

Question 26

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

Answer 26

True

Question 27

You must dive within limits of RDP, not computer? T/F

Answer 27

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 ______

Answer 28

40m/130’

Question 29

If a diver doesn’t have a computer he/she can just share? T/F

Answer 29

False they just use the RDP

Question 30
