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.

Maintaining TKS Panels

ByHank Gibson June 14, 2016June 14, 2016

When cleaning airplanes, the majority of people don’t know how to properly maintain their TKS panels.  TKS panels provide wing leading edge, horizontal stabilizer leading edge, and, in the case of FIKI airplanes, vertical stabilizer leading edge de-icing protection.  For those not familiar with them, they are metal strips that have thousands of holes drilled into them where the TKS fluid seeps out. They have become quite prevalent on Cirrus aircraft, the Cessna TTx, and Mooney aircraft manufactured in the last decade or so.  The system is also known as a weeping wing system.

Being on the leading edges, these panels pick up bugs very easily.  For the uninitiated, it would make sense to just use normal airplane cleaner to spray the panels and scrub the bugs.  Don’t!

Using anything that contains Methyl Ethyl Ketone (MEK) as that can harm the TKS bladders behind the panels.  Any aircraft cleaner containing wax could cause the pores to clog, preventing the TKS fluid from properly seeping onto the wing.

What’s the best thing to do?  Soap and water with a soft cloth is a good start (again, make sure it doesn’t have wax in it.  Dish soap would be suitable).  No hose available?  Just simply turn the TKS system on, let it run till you start to see fluid drip off the wings onto the ground, and use the fluid to clean the panels.

A soft cloth would work fine, but, if the panels are really buggy, take a green scouring pad to do some scrubbing.  Just make sure the scrubbing motion is up and down with the grain, not side to side.  You can find the green scouring sponges on the dishwashing aisle in the grocery store.  Just leave one in the hangar for when you need it.

Simplified Instrument Approach Briefing

ByHank Gibson August 27, 2016September 12, 2016

In instrument flying, I am all about keeping things simple.  There is a ton of detail that an instrument pilot can get bogged down in.  When an instrument pilot gets bogged down, he gets distracted from flying the airplane.  When he gets distracted from flying the airplane, dangerous circumstances can happen.

I like to keep things simple.  When I first started instructing, I developed a very simple instrument approach briefing that captures everything that is necessary on an approach plate, but prevents getting bogged down in the details.

I call it the BBC instrument approach briefing.  Here it is:

Brief

First things first.  The first step of an instrument approach briefing is to brief the approach plate.  There are a bunch of acronyms out there that instructors tell their students to memorize that only cause confusion instead of helping get the plate briefed.  To keep it simple, just work your way across the plate and you’ll get all the information you need.

Start in the top left hand corner of the plate, with the approach course, then work your way right and down, as follows:

• Approach Course (or Nav frequency if flying a VOR/ILS/LOC)
• Runway information
• Notes (these are good to brief the night before as a lot are irrelevant to GA pilots
• Missed approach
• Frequencies
• Planview and MSA
• Profile View and Minimums

Simple enough, right?

Build

Now that you know what you are planning on doing, you can now take the second step in the instrument approach briefing and build the approach in your GPS.  You know your approach type, you know your transition, and you know what your minimums are.  Taking all that information, you can now build it in to your system.

Checklists

Once everything else is done, don’t forget the checklists.  The descent and before landing checklists still need to be done as part of an approach.  The best time to do these is before joining the approach so that you don’t have to worry about flying the approach and looking at a checklist at the same time.  Even better, memorize the checklist and you don’t have to look at anything!

Most importantly, you want to be configured properly for the approach by the final approach fix.  Gear, flaps set, power set, so all you have to worry about at that point is following the needles and trusting your instruments.

Pancake Fly-In At KCVB

ByHank Gibson November 28, 2014

For those of you in the Hill Country looking to kick off the Christmas month right, head over to the Castroville Airport (KCVB) on Saturday, December 6th and get yourself a short stack of flapjacks.  For just $5, you can get yourself a good hearty breakfast that includes coffee or juice and bacon or sausage.  The eating starts at 0800 and goes until 1200, local time.  Come with an empty belly and an empty gas tank as CVB currently has some of the lowest priced gas in South Texas, currently listed at $4.70/gallon.

There will be plenty of hangar flying, lots of airplanes to look at, and most importantly, lots of pancakes!

Recurrent Flight Training

ByHank Gibson August 7, 2014August 7, 2014

As all pilots know, the Federal Aviation Regulations require licensed pilots to go through recurrent flight training in the form of a Flight Review every 24 months.  The regulations require 1 hour of ground review and a 1 hour flight.  This is all that a pilot has to do to legally maintain his or her VFR currency to fly alone in an airplane.  Of course, when passengers are aboard, the pilot has to have done 3 takeoffs and landings in the previous 90 days.

What if the pilot in question hasn’t flown in 20 years?  All the regulations require is 1 hour of ground review and a 1 hour flight.  Kind of scary, isn’t it?  (Any instructor worth his salt would not, however, turn a pilot loose with just those flight review minimums if they haven’t flown in 20 years without an extensive amount of recurrent flight training)

Now, a lot can happen in 2 years in between those flight reviews.  Regulations change, airspace is modified, and skills change (for the better or worse, most often for the worse over a period of not flying).   For a current pilot who flies once or twice a week, those minimums are no problem.  Here’s the thing, though.  Even those current pilots typically don’t do a lot of stall practice or emergency procedure practice on their own.  These are the most critical areas of flight and to only do them every two years leads to a lot of rust building up, sometimes even causing safety concerns in some instances.

How to remedy this?  Scheduling recurrent flight training as often as possible with a good instructor who puts you through your paces.  Do this often enough and stalls will become second nature.  The stall warning horn goes off?  Well, lower the nose and add power.  Engine failure?  Switch tanks and set best glide.  Recurrent flight training allows you to become as familiar as possible with your airplane, allowing you to know what to do in every circumstance.

What’s a good recurrent flight training schedule?  There are several options out there.  The WINGs program is a pretty good option, though you will only have 3 flight training sessions in those two years instead of 1, but it’s a good start.  In recent years, the FAA has put out Advisory Circular 61-98B encouraging pilots to begin personal currency programs for themselves.  The suggested schedule for VFR recurrent flight training is every 4-6 weeks.

Texas Top Aviation highly recommends this suggested schedule, for both VFR and IFR.  The AC doesn’t have a specific recommendation for IFR recurrent flight training, but flying 2-3 approaches a month with an instructor helps keep pilots as proficient as possible in the IFR environment.   This way, the instructor can introduce circumstances in a controlled environment that simulate abnormal conditions that might possibly be encountered in flight.  If those abnormal conditions are encountered, then it will be second nature on how to handle them, leading to less accidents and safer flying habits.

Try to schedule your recurrent flight training every 4-6 weeks and your piloting skills will stay top notch, keeping you safe and proficient in every circumstance.
