Quiz - Skills & Environment - Diving at Altitude

[Pedro Burrito]

Good morning from cooler and wetter than yesterday Switzerland!

From the Skills and Environment section of the PADI Dive Theory Exam:

Special procedures must be followed when diving at altitude because:

a. nitrogen (sic) narcosis may occur at shallower depths.

b. the ambient atmospheric pressure at altitude is less than at sea level.

c. actual depths must be converted to theoretical depths to find no decompression limits in the RDP™.

d. all of the above are correct.

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

I'd like to think this was a pretty easy question without having to do any extra studying!

I thought so, but was very wary of trick wording.

An intelligence analyst friend of mine says the key to success is, "Listen to the question, understand the question, answer the question." He points out that if someone asks what time it is, don't tell them how a watch works. And my first mentor in the teaching business said, "Tell them what they need to know, not everything you know."

Wise advice..........My mantra to the folks who work for me is that "Less is more."

Yes Yes! This is another question that is clear to me. But, let's wait....

This should be an uncontroversial question

...

Well maybe someone should question how the RDP was adjusted for altitude

The RDP doesn't need adjusting. It is the depths (actual to theoretical; theoretical is always deeper than actual) and ascent rates (go slower!) that need adjusting.

I meant to say how the RDP are used. You are correct.

I believe there are special tables for altitudes above a certain level (1,000' I believe). True?
