Altitude Chamber Flight

Brad in an oxygen maskA few weeks ago I had the pleasure of attending an FAA Aerospace Physiology class at Beale AFB outside Marysville, CA.   While the words Aerospace Physiology might sound a bit intimidating, the FAA simply says that Aerospace Physiology deals with the physical and mental effects on flight aircrew personnel and passengers.  That being said, the primary focus of this class is to teach you about the affects altitude, and decreased oxygen, have on the human body.  Anyone who holds a current FAA Medical Certificate may take the class at about a dozen or so locations around the country, at a cost of only $50.   If you are interested, you can learn more about the training and other on the FAA’s Airman Education web site.

This class is required component of your training and certification if you are going to be flying pressurized aircraft, and the conclusion of the training you are given FAA Form 3150-1, which is often referred to as an “Altitude Card”.  So why did I take the class if all I am flying is non-pressurized C172s?  Why not!  Seriously, I am always open to any form of training on new and old topics alike, and since reduced oxygen can have an effect on the body at almost any altitude I think the training is worthwhile for most any GA pilot.

I can see the wind

A few weeks ago, I showed up for a lesson on what was a fairly windy afternoon.  Nick said that given what he wanted to accomplish, it might not be the best day for us to go flying.  While I never like to hear that, I do understand why he said it and I do trust his judgment.   Before we made the final call, we sat down at the flight schools computers to check the weather. 

I pulled up the usual sources and found that conditions varied greatly in the area, but that the winds definitely seemed to increase as we got closer to the practice area around Stockton, where it was reportedly gusting around 25 knots.  We quicly came to the conclusion that it would be more productive if we stayed on the ground, but as one last check of the conditions Nick showed me a page on the USGS web site where you can see a dynamic graphical model of the  winds in and around the San Francisco Bay Area.  A picture doesn’t do it justice, you have to see it in motion for the full affect.  The best time to look is in the afternoon (Pacific time) when the afternoon winds have picked up.

Bay Area Wind Model

Pretty neat huh?  What’s interesting to me is that you can see the influence the local topography has on wind speed and/or direction, with areas visible where the wind quickly accelerates or changes direction.   It is simply a model that describes the flow of wind at a given time, so I guess that means that it simply shows you what it thinks the winds are doing based on observed data.  It models the winds at the surface so it is of minimal use for flight planning information, and who know how accurate it really is, but it is cool!

Mmm, yeah… I’m gonna need those TPS reports.

Red StaplerI know, I know, I am way behind here.  As I write this I currently have a backlog of five or six lessons to document.  Shame on me!  Until  about a week ago, I had been putting long hours in on a BIG project at work, and it seems like my entire life has been on hold.  My mind has been so occupied with this project that I have no idea what happened to the last half of May and first half of June.  With the project now somewhat behind me, I am now playing catch-up in all aspects of my life, including this blog.  Don’t worry, I haven’t lost interest, my plate has just been full (more like overflowing).  One thing is certain, I’ve come to realize that my day job is getting in the way of what I really want to be doing! ;-)

Traffic, 12 O’clock

Traffic from VansAirForce.netNo, not that type of traffic, but web traffic.  As in, a lot of visitors to my blog over the past few days.

Where did they all come from?  Well, my friend Doug Reeves, who runs the mother-ship of RV related web sites, VansAirForce.net, said some nice things about my blog on the VAF home page.  Actually, this is the 2nd time he has mentioned it in a few weeks; Thanks Doug!  He is also working on his instrument rating, but he is going to be doing his training in his RV-6.  I am so jealous! ;)

While it may sound like a bunch of butt-smooching, VansAirForce.net is simply one of the best aviation web sites around, and is the definitive source for all things RV.  Doug has devoted a large portion of his life to providing RV aircraft builders (like myself), pilots and fanatics a place on the web to call home, and we all appreciate his efforts very much.  Not only does Doug use the site to serve his fellow aviators, he uses it as a mechanism to to support various charities to the tune of many $$$ a year.  VAF is simply a fantastic web site and I am honored that he mentioned my blog, and proud to be in some small way affiliated with VAF.

By all means, don’t just take my word for it, check it out for yourself.  However I must warn you, prolonged exposure to VAF could result in an RV aircraft in your garage or hangar.  :)

So that’s what the stripes mean!

This cracked me up.  If you don’t find it funny, too bad!

IFR Stage 1 Check - Passed

Windsock and CloudsI am happy to report that on May 25th I passed my IFR Stage 1 check.  For those of you unfamiliar withwhat a stage check is, it is simply a flight with a different (usually more senior) instructor where they evaluate your knowledge and skills up to that point in your training.  It is a very common practice in flight schools, and whether you are training for your private, instrument, or some other rating, there are often several stage checks along the way.  This was my first of three checks, and overall it went OK.  Just OK?  Yes, just OK.

I flew the check with Brian, whom I have never met.  He was once an active instructor with the school, but then maybe a little over year ago he got an airline job.  Now he instructs part time and since he doesn’t really have regular students he is often utilized for stage checks.

The stage check started with a round of Q&A on the ground, where I was asked the typical questions about things like the FARs, equipment requirements, currency, and aircraft systems.  This was all fairly easy, and since I had previously been given a copy of the stage check form I was able to brush up on any weak spots in advance.  My knowledge of the required topics was solid, and I quickly found myself done with the ground portion and headed out to the airplane.  I wish I could say the flight portion of the check went as well as the ground, but I can’t, so I won’t.

IFR Lesson 11: DME Arcs

We covered something new today (5/21), DME Arcs.  Nick spend about 20-30 minutes educating me on the finer points of DME Arcs, and then took me into the Sim for a bit of hands-on practice.  What is a DME Arc you ask?  According to the FAA, DME Arcs provide transitions to the approach course, but are actually part of the approach segment.  Said another way, they are a portion of Instrument Approach Procedure (IAP) that transition the aircraft from the enroute phase of flight to the intermediate or final segments of the approach.  DME Arcs are specified as distances from a VOR-DME, and never based on and ILS or LOC DME as they do not provide omnidirectional course information. 

Flying a DME Arc is akin to flying a control line model; Think of the airplane as having a string, of a specified length, from the wing to the VOR-DME.  You simply fly a segment of a circle, called an arc, a fixed distance from the VOR-DME.  Using the Redding (RDD) LOC/DME BC RWY 16 approach as an example (below), from either of the initial approach fixes (IAF), FOLDS or GARSA, you would intercept and fly the 17nm DME Arc to the approach course of 162°.  Sounds easy, right?
