Introduction to DRVSM

Domestic Reduced Vertical Separation Minimum (DRVSM), also designated as RVSM, is a new altitude structure program in the U.S. that has been in use in numerous regions of the world and in designated flight tracks across the Atlantic Ocean since 1977.

It has been designed around the principals of:

  • Extending the usable airspace at and above FL290 (29,000 feet MSL) to FL410 to enhance ATC flexibility with traffic flow
  • Helping alleviate crossing traffic and conflict points in high density airspace
    Increasing airspace capacity
  • Providing enhanced operating efficiencies of flying at more fuel efficient flight levels and user preferred routing
  • Reducing ATC controller work load

DRVSM is currently the designation of RVSM airspace and operations within the United States. The designation DVRSM is synonymous with RVSM and it currently identifies all intended Reduced Vertical Separation Minimum (RVSM) airspace operations and is designated as the airspace beginning at FL290 and extending up to and including FL410.

A Really Fast Flight from DEN to BNA

Posted by Jeffrey on 16th February 2009

Yesterday we did a flight from Denver (DEN) to Nashville, TN, (BNA). There was a huge tailwind and we flew faster over the ground than I’ve ever flown in the CRJ-200.

Ground Speed 604 kts

CRJ200 Ground Speed (GS) 605 kts

At one point we had a ground speed of 605 kts (694 mph) with a tailwind of 173 kts (196 mph), even though we were only going Mach .74.

If you are wondering how I figured out the conversion from knots to miles per hour, it is simply

MPH = KNOTS x 1.15  

It was impressive to look down and see the ground literally slipping by. It was a very clear night and even at 33,000 feet (FL330),  you could really sense our speed which was awesome.

Anyway, I took a picture of the multi-function display (MFD) while enroute.

And here is the flight log that was downloaded from Flightaware.com as well. This was just a copy and post, so if you would like more details, you can see the whole flight log by clicking here.

Can You Fly and Have a Life, Too?

Posted by Jeffrey on 14th February 2009

Recently I got an email from Dwayne in Georgia that subscribes to this blog. He had some very interesting questions about flying that were a lot of fun to answer.

I’ve copied our email discussion below. Have a read and see what you think. I would really like to hear your comments about the discussion. Also, Dwayne had some great suggestions for future articles. Again, if you would to see a particular aviation article or an article about being a professional pilot, just let me know.

OK…here is the email. Dwayne’s questions are in blue and my answers are in black:

Dwayne: I just wanted to say thanks for your blog. It has given me inspiration to make my dream happen. A little about me. I am a commercial pilot, single and multi, and a single engine CFI. In September of 2001 after finishing flight school, I was flying with the State of Georgia on an internship that I earned while finishing at the top of my class in flight school. I had been with them 4 months and had about 450 hours in the King Air C90B, then September 11th happened. I have not flown more than 50 hours since then, and never thought it would be possible to get a job after that, but I understand they have dropped the minimum hiring requirements. I have about 1300 hours, and 500+ multi time now. I am 39  and married with 2 kids, Beau-3 and Drew-19 months old. I have been in the Real Estate business since, and am doing really well even in the market we are in today. I guess I have s few questions you might be interested in answering.

 

Would I still be able to sell real estate, with my wife being my business partner even though I might be away 50% of the month?

My Two Aviation Headset Review

Posted by Jeffrey on 12th February 2009

There are two aviation headsets that I really like: Bose QuietComfort and Sennheiser HMCE-25-KA. There is no doubt about it, Bose is a leader in sound! Their products are compact, good looking and top quality! And no doubt the Bose® QuietComfort® 2 Acoustic Noise Cancelling® Headphones is an outstanding headset with dual functionality: great noise reducing while riding on an airplane and while flying one. But there is some competition on the horizon.  Personally, I wear and recommend the Sennheiser HMEC-25-KA ANR Headset but other headsets have been catching up - I just don’t think they market as well.

Curious about what ANR stands for, click here.

How Is the Sennheiser Different from the Bose QuietComfort 2?

Medical Illness on an Airplane

Posted by Jeffrey on 8th February 2009

Illnesses happen on airplanes, too! I was reminded of this today.

We were in Calgary and we had just pushed back from the gate on our way to San Francisco when we got a call from one of our flight attendants. A passenger had taken to feeling ill and the flight attendant needed a moment to evaluate her.

The flight attendant smartly moved her up to an open first-class seat and though the passenger stated that she felt a little bit better, she was still not feeling well.

That statement made this a very easy decision for me. “Back to the gate!”

In My Mind

My thought process was “better here, on the ground and near the gate, rather than at 37,000 feet with the nearest airport 150 miles away.” This almosthappened to me once flying from Atlanta to Colorado Springs but luckily there was a doctor on board and the flight attendants administered oxygen and the passenger responded. We still had the EMTs meet us at the airplane and the passenger was taken off the airplane in a wheelchair but we didn’t have to divert. Close call.

So, once we committed to returning to the gate, a new set of priorities takes over. Notify operations and dispatch, get EMT/Paramedics to the airplane, keep the ill passenger comfortable and keep the other passengers informed.

Quick thought, one thing that I’ve been amazed at while flying for the airlines is that so many things unseen have to happen seamlessly to get one airplane off the ground and to the destination. One thing breaks down in the process and there goes your on-time departure. I’m always amazed at the complexity of the process.

Setting Priorities

It is no different when you switch from “go fly mode” to “emergency mode.” Things again have to happen in a particular order in order to work. So once we decided to return to the gate, I had my responsibilities, the first officer had his, the flight attendants had theirs, the gate agents had theirs, and the EMT had theirs. We first notified operations who collected the information about the passenger and passed it onto the EMTs. If it works right, it should only take a few minutes for the EMTs to get to the airplane and assess the passenger. All the while, everyone is busy doing “their” jobs. Then, after the passenger is either cleared to fly or removed from the flight, now it is time to get back to “go fly mode” and head for the destination.

From my perspective I have to decide whether I still have enough fuel or do I need to take on more. What about the bags? Has there been a change in the weight of the airplane that needs to be considered? What about weather? If we have already de-iced/anti-iced, do we need to do it again. Is my flight plan still active? How are the passengers and my crew doing. There is a lot to consider and it takes team work to get it done. Ultimately the captain makes the final decision but you have to have input from your crew if implementation is to be successful.

So this particular passenger was removed from the flight and we were notified that the passenger would be taken to the hospital for evaluation. Yeah, that could have happened at 37,000 feet and we would have been a lot worse off than we were now…i.e., the passenger would have had to suffer longer and we would be more than just an hour behind schedule.

Time To Re-Evaluate The Decisions

Now once we were finally airborne it was time to evaluate the events that had occurred and see if there was something that we could have done differently. To me it seemed that this was a fairly simple exercise, but I did score poorly on two accounts:

I should have told the flight attendants to collect as much information about the passenger as possible, as quickly as possibly, then get the information to either me or the first officer. 

It was then that I realized that we needed a checklist when something like this happens. I found the acronym SAMPLE which provides a nice beginning guideline for evaluating the situation:

  1. Signs and Symptoms
  2. Allergies
  3. Medications
  4. Past History
  5. Last Oral Intake
  6. Events Leading Up To the Present Illness or Injury

Then, once I saw everything working out, I should have switched my attention sooner to getting the airplane airborne again. As it turns out, we usually do an automated manifest that calculates everything for us, but in this instance, there was a data mismatch so we had to do a manual manifest which takes minutes longer. I didn’t see that one coming but I will remember it for the next time.

It Is a Team Effort

A lot of credit goes to my flight attendants, they did their jobs very well. One of my flight attendants did a quick water service for the passengers while we were waiting, which I know the passengers appreciated. When we got to San Francisco, everyone seemed very appreciative for our efforts and that is always appreciated by us.

Anyway, I hope this entry provides some insight into what happens when you have an illness (emergency) on your flight. I feel I got off easy on this one, but maybe it happened for a reason. Maybe someday I will have to pull upon what I learned and practiced today on some future flight where the decisions will not be so clear cut. Regardless, that is basically what flying…and life, if you want to take it that far…is all about. Learning from your experiences and applying them to your life as necessary.

Well, till next time…Be Safe…
