Lightspeed Zulu 2 vs. The Bose A20

ByHank Gibson September 13, 2014

The debate about which headset is the better product will never cease.  We do know this for sure, though, Lightspeed and Bose make the best noise canceling headsets out there.  David Clark’s offering doesn’t match up with these two.  Newcomer AKG has a light (weight-wise that is, as the headset is equipped with a pair of LED lights as well) ANR headset that the jury is still out on.  For now, Lightspeed and Bose sit atop the ANR kingdom.

The comparison for this article will be between the Lightspeed Zulu 2 and the Bose A20 headsets, both of which I have used quite extensively in my flying career.  I am officially in the Lighspeed camp at this point and after reading my comparison below, you’ll see why.

ANR Functionality

Between the two, the Bose A20 cancels out more noise, no argument there.  This isn’t to say that the Lightspeed Zulu 2 doesn’t.  Quite the opposite, actually.  The Lightspeed Zulu 2 does a great job of canceling the noise.  But with the A20 on in a C172, you can barely hear the engine running.  The difference before you press the power button and after is extremely noticeable.  I had one client turn to me after turning on the noise canceling function of his new A20 headset and state, “These things are awesome!”

The other advantage Bose has is a continuation of the noise canceling.  About the only thing I don’t like about the Lightspeed is if you don’t have the headset sized just right on your head, each time you turn your head to look at something, then the suction gets broken around the ear cup and you get some ambient noise.  My glasses probably don’t help with this.  It’s not that big of a deal, you just have to readjust the size of the headset, but, since I’m a little OCD, it bugs me.  Once I get the set sized right, it’s smooth sailing.

Comfort

Far and away, the Lightspeed Zulu 2 is much more comfortable than the Bose A20.   I flew for 5 hours in the right seat with my Lightspeed set on the other day.  I switched to the left seat for the last leg and used the owner’s A20 headset since it was plugged in on that side already and I noticed quite a bit of difference.  The ear cups seemed to press against my head more.  The pad on top of my head didn’t seem to be as cushiony.  It just wasn’t overall as comfortable as the Lightspeed Zulu 2.

Bose has made a lot of progress from their original noise canceling headsets.  Those didn’t have much of a cushion on top at all.  After about 2.5 hours, the slim ear cushions began to dig in to the side of your head.  So, the A20 has made some progress, but the Lightspeed Zulu 2 takes the cake in comfort.

Weight Distribution

“Wait!”  You Bose boys scream (no pun intended).  “The A20 is lighter than the Zulu 2!”  While this is true (the Zulu 2 weighs in at 15.7 oz while the A20 is only 12 oz), the way that weight is distributed makes a massive amount of difference.  The Lightspeed Zulu 2 feels lighter on top of your noggin than the A20 because the weight of the A20 is firmly planted on the top of your head in a single point.  With the Zulu 2, the weight is distributed evenly across the top of your scalp, so even though the set is heavier, it feels lighter on your head because the weight is not all concentrated on one point.

All this adds up to why I like the Lightspeed Zulu 2 more than the Bose A20.  As for a practical example, I wore my Lightspeed Zulu 2 set for 9.1 hours one day two weeks ago.  Needless to say, it was a long day.  But, once I climbed out of the airplane, I had no pain on the top of my head and only a very little where my glasses ran along the side of my head.  Now I call that a winner.

PopSocket iPad Yoke Mount

ByHank Gibson October 24, 2017October 29, 2017

I was recently clued in to a really cool (and very cost efficient) iPad yoke mount.

It’s called a PopSocket and you won’t find it on any aviation website (I have to credit Joe Casey of Casey Aviation with this nifty find).

It’s very simple.  You take the mount (see right) and stick it to your yoke.  Then you pick one of a ton of designs from PopSocket and stick it to the back of your iPad (you can even create your own design!  B2 Bomber anyone?).

It’s low profile, doesn’t get in the way of anything, and is easily removable.  The PopSocket mounts are $10 apiece (depending on the size of your iPad, you may want to get 2).  The PopSocket is $10, so at the most, you’ll be in $40 plus tax and shipping.  Most mounts on Sporty’s are upwards of $50 and require a lot of installation, are big and bulky, and usually require lots of juggling to get the iPad in and out of the mount.

Give the PopSocket a try.

That Pesky Rudder

ByHank Gibson July 20, 2015July 27, 2015

Whenever I get in an airplane with a pilot for recurrent training, I can assure myself that I will mention rudder usage more than once during the flight.  If it is in a tailwheel (or if the pilot is doing tailwheel training), I’m going to mention the rudder a lot.  How do I know this?  Because basic rudder skills are actually one of the most difficult things to master in flying.

Let’s start simple.  What does the rudder do?  The dictionary definition is it controls the movement about the vertical axis of the airplane.  If you stick a pole down through the CG of the airplane and rotate the airplane around that pole, this is the vertical axis.  Looking at it another way, the rudder moves the airplane’s nose left and right.  Keep this in mind as we move on.

Every pilot thinks about the rudder during the takeoff roll.  Because of the torque effect, the pilot must add right rudder during the takeoff roll to stay on the runway centerline.  Depending on the airplane’s horsepower, more rudder pressure is needed in higher powered airplanes.  The problem usually shows up once the airplane gets in the air.

In the worst situation, after takeoff, the pilot will set both feet on the floor and completely disregard the rudder.  Torque effect and now P-factor are continuing to cause the airplane to yaw left, causing the need for right rudder.  With his feet on the floor, though, the pilot is allowing the airplane to yaw.  It’s not terribly noticeable for him in the front seat, but the back seat passengers (especially in a six seat or larger airplane) are certainly feeling it.

One particular problem spot on the climb is the climbing left turn.  In a climbing left turn, training says to add left rudder since it is a left turn (see below for the reasoning).  But, since the airplane is climbing and therefore experiencing left yawing tendencies due to the aforementioned effects, the pilot needs to continue pressing the right rudder, though the pressure won’t be as much as in a straight climb.  Watch the ball the next time you make a climbing left hand turn and it’ll make a believer out of you.

I find only a handful of pilots are this egregious.  Most pilots have rudder problems in turns and in turbulence.  We’ll tackle turns first.  As we all learned when we first started flying, due to adverse yaw, a pilot must add rudder in the turn’s direction.  Again, this isn’t usually where the problem shows up.  During the rollout is the problem area.

Let’s take a turn to the left.  The pilot rolls in, adding left rudder, arrives at his heading, then begins to roll out with the ailerons.  Left adverse yaw is now being experienced and right rudder is needed to smoothly transition back to level flight.  Need some visual assistance?  Watch the nose the next time you make a turn. If you are working the rudder properly, the nose will pivot on one point in the horizon.  If you aren’t using the rudder properly, the nose will draw a U shape on the horizon.  Try making some turns without rudder, see what it looks like, then use the rudder properly.  You’ll notice a big difference.

Finally, let’s talk turbulence.  As we all know, turbulence in the hot summer afternoon is quite pronounced. When the airplane experiences a bump, it usually doesn’t bounce straight up in the air.  There is usually some kind of rolling motion involved.  As the pilot corrects this rolling motion by moving the ailerons, adverse yaw is experienced (just like rolling into and out of a turn that we talked about above), so rudder is needed.  There isn’t a need to stomp on the rudder or you’ll cause the airplane to severely yaw in the other direction, but rudder pressure is needed.

Final approach is where this gets most pilots.  By controlling the nose and not allowing it to move around on final by using the rudder, this will make your approaches a little more stabilized leading to a more successful landing.

Feeling lost when it comes to the rudder?  Ask your instructor the next time you go fly to do some rudder exercises.  Most instructors don’t emphasize these basic stick and rudder skills which leaves pilots lacking as they move on in their aviation lives.  So make it a point to do some basic rudder work the next time you fly with your instructor.

Avidyne Entegra Chart Updates

ByHank Gibson August 19, 2014

There are a number of airplanes out there equipped with the Avidyne Entegra PFD and MFD system, most notably the Cirrus SR20 and SR22 models from the early 2000s and the Columbia 350 and 400 from the same era.  The Entegra is pretty simple and easy to learn, but doesn’t have the capability that it’s Garmin glass panel counterparts do (I have not, however, tried the R9, which could prove much more capable than it’s predecessor).  I have found that pilots master the Entegra a lot quicker because of the reduced functionality.

One of the nice features of the Avidyne Entegra is the CMAX Chartview option.  With a yearly subscription, you can get all the Jeppesen approach plates and airport diagrams for the entire US on your MFD.  Just like your GPS, though, you have to update the charts monthly to keep them legal.  After a period of time when you don’t keep up with the updates (I believe it is 90 days), then the charts disappear.

The update process is a little tricky if you don’t have someone to explain it to you.  Once you go through it a few times, you’ll have it down pat.  Here’s the process for the Avidyne Entegra Chart Updates.

Jeppesen Subscription

The first step in performing your Avidyne Entegra Chart Updates is to create an account with Jeppesen, who handles all the GPS NavData and MFD Chart updates for both Garmin and Avidyne.  If you already have a Jeppesen subscription, you can skip down to the next section.  To do that, simply go to jeppdirect.jeppesen.com, and then do the following:

• Click on Avionics Data on the upper left hand side
• Click “Purchase Avionics Subscription”
• Then, click on “Create Account” in the new users section
• Once you’ve created an account, login, then put in your aircraft information and select 1 update for the Avidyne Entegra EX500 EX 5000
• Click Continue at the bottom and you can put in your payment information

Software Needed

There are two different programs depending on if you have a PC or a Mac.  If you have a PC, you need the Jeppesen Services Update Manager (JSUM).  If you have a Mac, you need the Jeppesen Distribution Manager (JDM).  Download whichever one you need, then login, and your updates will show up.

Downloading the Avidyne Entegra Chart Updates

First, we’ll go through the process of performing the Avidyne Entegra Chart Updates process for a Windows computer, using JSUM.    You’ll need two 2 GB USB drives formatted to FAT 16.  Here’s how to format to FAT 16.

• Go to My Computer after inserting the USB drive
• Right click on the drive
• Click on Format, then select FAT and press OK

Once the USB drive is formatted to FAT16, open up the JSUM program.  Login and your updates will be displayed on the screen

• You’ll need to set the Avidyne CMAX Key Code
  • Right click the Avidyne Electronic Charts Service and click Set Avidyne Key
  • To get the key code, visit MyAvidyne.com and create an account using your JeppView subscription number and your serial number for your Avidyne MFD (found on the AUX page) and your PFD serial number (displayed on startup when the PFD is warming up)
  • Once you get the Key Code, copy and paste it in the window and click OK
• Click on the service and click Start
• The program should automatically detect the drive (if it doesn’t, click browse and select the drive)
• Click Continue and the charts will start downloading and automatically programmed to the USB drive
• If you are updating NavData on the MFD as well, follow the same steps as listed above in order to update the NavData

Next, we’ll go through the Avidyne Entegra Chart Updates process on a Mac, using the JDM program.  You’ll need two 2 GB USB flash drives formatted to FAT 16 (the easiest way to format to FAT 16 is on a Windows computer, using the process above).

• Open the JDM program and login
• Insert the first USB drive
• You’ll need to set your Avidyne CMAX Key Code
  • Click Service Details under the Electronic Charts Service
  • Click Set Avidyne CMAX Key Code
  • Program automatically detects the USB drive
• Click and drag the Electronic Charts service over to the USB and release
• The service is downloaded and copied to the USB drive automatically
• Eject the USB drive
• Insert the second USB drive (or plug the USB drive in to your MFD, do the update, then reformat the drive) and follow the same steps for the NavData

Updated the MFD with the Avidyne Entegra Chart Updates

Once everything is programmed the your USB drives, the rest of the process is simple.  Just go out to your airplane, plug in the first USB drive with the Electronic Charts on it, turn your battery on and the avionics master, and the system will upload the information automatically.  Once it’s finished, turn everything off, pull the USB drive out, then insert the second USB drive and do the same thing.

Now, you’re all updated!

If you’d like to see a video on the process, Jeppesen has some very good videos on the updating procedure.  The links are below.  If you have questions, please contact Texas Top Aviation and an expert will help you through the process.
