How long should my no fly time last after my dive?

Published

on

By: Jon Kieren

As divers, you have all seen the little airplane icon on your dive computer with a countdown timer next to it. Understanding where that number comes from and how to use it to plan your trips is important to avoid missing dives, or worse, having to miss your flight back home!

Why is there concern for flying after diving? 

We are all aware of the reasons for staying within no decompression limits and performing safety stops, right?  Well, think of your no-fly time as a “decompression stop” prior to flying.  After a dive, we still have a significant amount of excess nitrogen dissolved in our tissues.  If we ascend directly to altitude (generally above 6000ft), ambient pressure will decrease enough that we are at risk of having that nitrogen form bubbles just like if we overstay our no-decompression limits and make a direct ascent to the surface.

The cabin inside an airplane is pressurized, so why does it matter? 

While the cabin is pressurized, it is typically pressurized to around 8000ft.  This is above the typically accepted ceiling of 6000ft, so we need to wait long enough for our tissues to off-gas before hopping on our flight home.

How does the dive computer calculate our no-fly time? 

Each computer manufacturer uses a slightly different method, however they will generally use their no-decompression algorithm just like they do on the dive.  The no-fly icon essentially represents a mandatory decompression stop before our bodies have off-gassed enough for ambient pressure to be reduced to more than 6000ft of altitude.  Because many manufacturers use different decompression algorithms and every dive profile is different, it is difficult to generalize across the board how long a diver will have to wait before their computer’s no-fly time clears after a dive trip.

How do we know when to schedule our flight home? 

Luckily, Divers Alert Network (DAN) and the Undersea Hyperbaric Medical Society (UHMS) have done the work for us.  They conducted a study on flying in commercially pressurized aircraft (Sheffield and Van 2004), and arrived at the following guidelines:

  • A single dive within the no-decompression limits: 12 hours
  • Repetitive dives of multiple days of diving: 18 hours
  • Decompression dives (planned or unplanned): substantially greater than 18 hours

As a general guideline, DAN recommends allowing a minimum of 24 hours before flying to account for any variables (fatigue, dehydration, etc), as well as emergencies in flight such cabin depressurization.

So while your dive computer’s no-fly indicator is an additional tool to verify you are clear to fly, it is difficult to estimate what that no-fly time will be in order to plan a return flight home.  When planning your diving vacation, it’s recommended that you allow at least 24 hours after your last dive before your scheduled flight.  As a bonus, this ensures all of your gear will have plenty of time to dry out before you pack it away in your bags.

As pockets around the world are reopening, there is a growing demand for PADI® Professionals in many key markets worldwide. To support its membership, PADI has launched a full revamp of the PADI Job Board to help dive centres and resorts build winning teams and connect dive professionals with exciting job opportunities. The new platform makes it easier than ever to search, find and connect the world’s best dive professionals with scuba jobs available at PADI Dive Centres and Resorts around the globe.

“For the first time since the pandemic began, new postings of job opportunities for PADI Pros on the PADI Job Board are coming in faster than they are being filled,” says Kristin Valette Wirth, Chief Brand and Membership Officer of PADI Worldwide. “This is a great sign of the industry bouncing back strong in several parts of the globe. Incredible dream job opportunities around the world for PADI Pros will continue to increase as customers flood back, requiring dive operators and resorts to increase recruitment and hiring in order to keep up. With this in mind, we’ve prioritised updating the job board platform to enhance the efficiency and effectiveness of connecting PADI Pros with PADI Resorts and Dive Centres to succeed.”

Accessible via the PADI Pros’ Site, the new job board offers a host of features to help PADI Dive Centres and Resorts manage job postings and candidates, and help PADI Professionals search and apply for jobs. The job board is also supported by in-app translations, so PADI Members can choose from more than 20 languages to view and post within the application.

The PADI Job Board has long served as one of the most visited pages on the Pros’ Site, with the launch of the new job board exceeding more than 31,000 unique views during the first two weeks of launch. Some of the new technologies and features aimed at further empowering PADI Pros, Resorts and Dive Centres are:

  • Manageability – PADI Retail and Resort members can more readily and flexibly post, edit, update and otherwise administer their job listings.
  • Resume posting – PADI Pros can post full resumes, making it easier for individual members and operators to find the best skillset matches that create winning teams.
  • Searchability – The job board is no longer simply a list. Pros and shops can search based on criteria without wading through irrelevant entries that don’t line up with what’s wanted or needed.
  • Direct connection – The job board allows direct connection so that operators can contact prospective hires for initial follow up.
  • Multilingual – Automated translation technology allows users to post and view listings in their language preference, reducing language barriers.
  • Notifications – Employers and candidates can enable notifications to be alerted of new applicants, job posts, invitations to apply for a job or interview, among others, so they never miss an opportunity.

“The PADI Job Board is a powerful gateway for employment opportunity throughout our membership infrastructure and provides the most global employment opportunities in the dive industry,” says Valette Wirth. “We expect the increase in job opportunities to continue to grow as travel rebounds. We will continue to prioritise supporting our PADI Members with the challenges they face during their recovery.”

PADI Women’s Dive Day 2021 highlights important role inclusivity plays in creating balance between humanity and ocean

Published

on

PADI®, the world’s largest ocean exploration and diver organisation, is celebrating with divers from around the globe tomorrow for the seventh annual PADI Women’s Dive Day on Saturday, July 17.

With the overwhelming support of the dive community over the last six years, PADI Women’s Dive Day has grown into a worldwide celebration of shared adventure, passion and ocean advocacy. The annual event is dedicated to fostering a global community that encourages divers of all genders, ages, races, backgrounds and abilities to safely and confidently explore and protect the underwater world. Year after year, Women’s Dive Day activities have addressed ties between diversity, inclusion and environmentalism – with this year’s events scaled accordingly for the COVID-19 pandemic.

“PADI Women’s Dive Day is an opportunity for divers everywhere to unite as a community with the common goal of creating balance between humanity and ocean,” says Kristin Valette Wirth, Chief Brand and Membership Officer of PADI Worldwide. “PADI has a wonderfully diverse and inclusive community of members and divers in 186 countries around the world.  We celebrate this diversity, as it is embedded in the ethos of our organisation. We take pride in the progress we’ve made to increase diversity, accessibility, and inclusion in our sport and constantly challenge ourselves to do more.”

Since its inception in 2015, the event has contributed to the significant growth in the number of female divers and subsequently, PADI Torchbearers™ who have shared and inspired passion for ocean conservation. The dive community is teeming with female divers who are marking remarkable contributions for improved ocean health and connecting their communities to local waters. Throughout the month of July, PADI is spotlighting the stories and perspectives of incredible #PADIWOMEN around the world who are leading change by example and opening doors for countless others to experience the ocean firsthand, including Zandile Ndhlovu, a PADI Freediver Instructor™ from Johannesburg, South Africa, who founded the Black Mermaid Foundation to make the oceans more inclusive.

“Together as a global dive community we can save our oceans,” says Ndhlovu. “Once people get to experience the ocean, it changes everything around how they’ve always looked at it. It begins to also feel like home, a place that they will always protect. And that is why it is important that there is always diverse representation in the ocean.”

Other notable women include Xochitl Clare, a PADI AmbassaDiver™ and marine biologist from California, United States, researching the effects of climate change on fisheries species; Cody Unser, a PADI AmbassaDiver who is working  to introduce more people with disabilities to diving and promote the sport’s therapeutic benefits; and 13-year-old Julia Aveline Rabenjoro a PADI Junior Advanced Open Water Diver in Kota Kinabalu, Malaysia.

“Learning to dive really transformed my life because it introduced me to a whole new intricate world that makes me feel at peace and it taught me how much we really depend on our ocean,” says Aveline Rabenjoro. “My greatest hope for the next generation of female divers is for them to grow in numbers and never doubt the difference they can make no matter where they come from or who they are. Together as a global diving community, we can further this by sharing our passion and love for diving with others who haven’t yet been lucky enough to explore beneath the surface.”

Divers and non-divers alike can connect with the motivating stories of PADI women and learn how they can join the community by visiting padi.com/women. They can find PADI Women’s Dive Day events in their area or participate virtually through social media conversations utilising the #PADIWOMEN hashtag.

Year-round, people worldwide can access PADI’s recently launched Conservation Activities Locator to find local events in their community. From joining an underwater lake cleanup in Connecticut to taking part in a week-long conservation workshop in Belize, ocean enthusiasts have a variety of experiences to choose from on Women’s Dive Day and beyond.
