PADI ADVANCED OPEN WATER QUESTIONS WITH CORRECT ANSWERS GRADED TO PASS

Primary dive skill - Return safely Secondary dive skill - Anything beyond returning safely Four central dive skills [GHSTS] - Good habits Situational awareness Task loading Secondary objectives desire 3 dive skill effects [DSIRE] - Make dives: efficient Reduce risk Integrate with other skills Biggest mistake involving secondary objectives - Forgetting they are secondary Situational awareness - What's going on around you How it affects you The 3 actions of situational awareness - Analyzing organizing filtering what your senses perceive Primary goals of gas management - Don't run out Keep a reserve For basic divisions of gas - Outbound Return Ascent Reserve Outbound gas - -descend -carry out secondary objective Return gas - Return to assent point Ascent gas - Ascend Safety stop Exit Reserve gas - Problems/emergencies 3 SPG [TARget]pressures - Turn Ascent Reserve Conditions that can make surfacing undesirable - Chop current Tech decompression Overhead environment When finding yourself lower on gas than desired and surfacing isn't the best option - Slow down Ascend to a shallower level Ascend No stop time points - No stop time remaining Ascending well within no stop limits Environment awareness - Changes : wave /current/ surge direction density (water) visibility temperature aquatic life Equipment awareness - Operation Fit Accessories Hazard's awareness - Dive planning Unexpected hazards Degree of hazard E.g. How many jellyfish? PRPD for depth awareness - Present depth Rate and direction of change physical barrier -descending too far Navigation orientation and location - Where you are/were/going Bee line to ascent point Buddy status (LiCS) - Location Communication safety Buddy safety concerns - Gas Hazards Thermal secondary objective Awareness - 2ndary obj. stays secondary When to quit the secondary Task Loading DSC - Dive 1st Situation 2nd Communicate 3rd Situational awareness goes from.... - ..inward to outward Under stress thinking becomes what ? - Slow and impaired S.M.R.T.B.D habits - Safety checks Mask on Regulator Breathing Buoyancy Turn with time Dive within your limits underwater navigation reduces (c.a.b.s) - confusion anxiety buddy loss surface marathons two parts of navigation - where you're headed how far you've gone distance estimation [K.E.C.] - kick cycles elapsed time cylinder pressure natural navigation - observations in the environment predive observations [W.O.o.D.S.] - water motion objects/formations depth finder sun direction/ angle descend oriented to... - your travel direction natural references [flights of the ray] - light/shadow water movement composition contour plants/animals sound dive compass features [spit bit] - dampened response direction at tilt degree numbers readable in low light lubber lines bezel lubber line - your travel direction compass use tips [I STRUT N U NAP] - intentional error on long distance share responsibilities trust the compass remember priority understand limits take time natural references use patterns navigate around obstacles allow for current practice on land sharing nav responsibilities - compass buddy/depth buddy nav patterns - out and back lines squares/rectangles triangles circles out and back line - straight line out same line back setting reciprocal course - follow compass on single heading At turn point, turn bezel 180 degrees turn until needle is within index marks t pattern navigation [SVSMOR] - small patterns agree on pattern with buddy visualize pattern (embodied simulation) surface and check position periodically move slow one pattern buddy remember heading around obstacles transponder nav - emits signal from boat picked up by dive instruments max depth of deep dives - 40 meters/130ft minimum for deep dives - 18 meters/60 feet depth limit factors - enviro conditions physical/mental state previous dives distance to assistance dive buddy's training deep dive objectives should be... - simple with singular task "suitable" deep dive gear - good working order appropriate for the environment "optimal" deep dive gear - superior performance at deeper depths optimal gear relates to - regulator alternate air source cylinder high performance 2nd stages - balanced adjustable models venturi-assisted models pilot valve 2nd stages alternate air should be visible in the triangle of... - mouth and lower rib cage corners H-valves - allow two regs on single cylinder common second stage color - yellow pony bottle - 2-4 litre/12-30 cubic foot deep dive cylinder - 12 litre/71.2 cu ft or larger
