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.

Determining Pattern Altitude

ByHank Gibson October 23, 2015October 23, 2015

Figuring out the pattern altitude at an airport should be pretty simple, right?  But, in this day of helpful technology, most pilots actually get it wrong.  How can you always get it right?  Well, it just takes about an extra 15 seconds.  Here’s how.

As outlined in the Aeronautical Information Manual, section 4-3-3, “traffic pattern altitudes for propeller-driven aircraft generally extend from 600 feet to as high as 1,500 feet above the ground.”  Further, in the Pilot’s Handbook of Aeronautical Knowledge on page 13-10, it states:  “1,000 AGL is recommended pattern altitude unless established otherwise.”

Okay, so for piston driver’s, we’ve got it narrowed down to 1,000 AGL (Above Ground Level for those who don’t like acronyms).  But wait!  There’s that very important phrase at the end of the last quote:  “unless established otherwise.”  That means not all airports have traffic pattern altitudes of 1,000 AGL, or else they wouldn’t put that line in there!

How do you find out what the TPA (Traffic Pattern Altitude) is for a certain airport if it’s not 1,000 AGL?  Great question!  Your first guess is probably to look on Foreflight.  Though this is a good start, it is not the full answer.

Let’s use an example.  Look up KAQO, the Llano Airport on Foreflight.  At the top of the page, the airport elevation is stated as 1,101′ MSL and the pattern altitude is stated as 1,902′ MSL.  From what we just learned, 1,902′ MSL is not 1,000 AGL, so is 1,902′ MSL otherwise established?

On the Airports page with KAQO pulled up, tap the A/FD tab, second to last on the left.  Scroll down to Llano Muni.  Read the whole entry.  Does it state in the entry that pattern altitude is different than 1,000 AGL?  It sure doesn’t.  So, because it is not otherwise established, pattern altitude at KAQO is 2,102′ MSL not 1,902′ MSL.

Where did Foreflight get that?  I have no idea.  Too often, though, pilots look at the Foreflight pattern altitude and don’t actually check the Airport Facilities Directory (A/FD).  Then, they get the pattern altitude wrong.

What does it look like when pattern altitude is otherwise established?  Look up KSGR, Sugar Land Regional, on your Foreflight app.  Foreflight states the elevation as 82′ MSL and the Pattern Altitude as 1,000′ MSL.  Is this correct?  Well, tap that A/FD button again and let’s find out.

On the second line of the A/FD entry, it says TPA-See Remarks.  Down in the remarks section, we find the following:

TPA-1000 (918) single engine piston acft, TPA-1500 (1418) for twin and turbojet acft, TPA-500 (418) for helicopters within 2NM.

Foreflight got it right this time for single engine pistons, but if you are in a twin, the pattern altitude is different.  What’s the lesson here?  Always check the A/FD and don’t always go by what Foreflight says.  The A/FD is always right and usually has a little more detail to help set you straight.

One last thing.  Both the AIM and the Pilot’s Handbook of Aeronautical Knowledge, when talking about pattern altitude, state, “When operating at an airport, traffic pattern altitudes should be maintained unless otherwise required by the applicable distance from cloud criteria in…section 91.155.”  91.155 defines basic VFR weather minimums.  So, to fully interpret what the AIM is saying, we have to take into account the type of airspace we are in to determine if we can safely and legally operate at pattern altitude at a particular airport.

For example, let’s say we are at KCVB, the Castroville Airport.  Pattern altitude there is 1,602 feet, which is 829 AGL.  CVB is Class G airspace up to 700 AGL, then Class E above that.  Let’s say there is a 700 AGL broken cloud layer.  Pattern altitude is 829 AGL, so you won’t be able to get up that high with a broken ceiling.  What altitude can you do pattern work at to stay legal?

Class G VFR weather minimums during the day below 1,200 AGL is 1 SM visibility and clear of clouds.  So, legally, you could fly at 699 AGL (which at CVB would be 1,472 MSL) while in the pattern and be legal.  Safe?  Maybe, but probably not if you are skimming the base of the clouds.  Is 1300 MSL a safer pattern altitude in this example?  Well, that is 527 AGL, so probably not, since towers tend to stick up that high sometimes.

Let’s go back to KSGR and put a 1,000 AGL overcast ceiling there.  SGR is Class D airspace and we already determined pattern altitude there was 1,000 MSL for piston singles.  VFR visibility and cloud clearance requirements in Class D airspace are 1,000 feet above clouds, 500 feet below clouds, and 2,000 feet horizontally from the clouds with 3 SM visibility.  In order to stay 500 feet below the clouds, you would be flying a 582 MSL pattern.  Safe?  Probably not, though it is legal.

To summarize, don’t take Foreflight’s word for pattern altitude.  Cross reference the A/FD (it only takes 15 seconds at the most) to verify.  If it’s cloudy, it’s really best to stay on the ground, but if you want to find out your legal pattern altitude with a cloud deck, cross reference 91.155.  I don’t recommend flying below pattern altitude because it is there for a reason.

A Proper Cross Country Flight Checklist (Part 1)

ByAndrew Robinson February 8, 2016February 11, 2016

I love cross country flights. Airplanes are designed to travel.  When I was instructing private students, my favorite lessons were always the first cross country flights. I looked forward to getting my students out of the pattern, away from the practice area, and showing them what they could really look forward to as a private pilot.

When I was in college, my friend and I borrowed his dad’s Cessna 150, did a cross country flight in it from Indianapolis to Kitty Hawk, then down the coast to Florida. We camped in the grass next to the airplane wherever the airport managers would let us and had our own aviation adventure complete with mechanical problems, unexpected weather, and interesting people along the way. These types of trips have produced some of the best memories and experiences that I’ve acquired during my aviation career so far.

Unfortunately, I know many people whose only cross country flight experience is what was necessary to satisfy their Private and Instrument training requirements. Some of them are nervous about the idea of venturing away from the familiarity of their home airport, while others are relatively new pilots who simply don’t know where to start planning a long cross country flight.

I’ve taken some notes on my preparations for an upcoming cross country flight that I’ll be flying in my dad’s Bonanza. I’m hoping this checklist might help others feel a little more confident that they have everything they need to get going.

Oil

Its always a good idea to bring a few extra quarts of oil. If you stop somewhere and find you need some, its nice to have the right kind on hand. Never assume that the airport you’ll be landing at next will have oil available.

Fuel Stops

I’ve learned the hard way that calling ahead to verify fuel availability can be extremely important. I landed at an airport in Ohio one beautiful Sunday morning to find that the FBO wouldn’t be open until much later in the day. Naturally, there was no other fuel available on the field. I hadn’t called ahead to verify the hours of fuel availability (I assumed they had Self Serve) and had only 2 options: wait a while for the FBO to open, or try and find somewhere else nearby that had gas. As far as price, www.100LL.com is a valuable tool for finding cheap fuel. Foreflight also has posted prices for 100LL and Jet A, but it’s still a good idea to call ahead and verify price and availability.

Batteries for electronics

It’s miserable to run out of batteries for a noise canceling headset with hours remaining in your flight. Bring spares, not only for your headset, but for your flashlight and other gadgets as well. Make sure your hand held GPS, iPad, and Stratus are charged (if you have them). I like to carry a charge cable and adapter as a backup so that I can plug things into the cigarette lighter.

Jumper Cables

We always carry the ground power cable in the back of the Bonanza just in case we ever need a jump. Last month, when I was flying down to Texas, I was glad I had them; we had a dead battery after our fuel stop and had to borrow some power from an FBO worker’s pick up truck. Don’t assume that wherever you are stopping will have the correct cable to jump your airplane, especially if it requires a specific plug.

Parking Fees

Every airport is different. I like to call ahead and find out how much the FBO is going to make me pay in landing/overnight fees. When I flew up to Buffalo last summer, I paid 25 dollars for parking at Niagara International (IAG). Had I parked at Buffalo (BUF), they would have charged me over $200.

Approach plates and charts

Make sure you have current approach plates and charts either physically available or downloaded before you blast off. Having a copy of an AFD is a good idea as well, be it digital or paper.

Rental cars

If you arrange it beforehand, many FBO’s will have the car ready for you upon arrival. You may also be able to drop the car off at the FBO when are finished, instead of taking it back to the rental agency. It sure is nice to have the car pulled up next to the airplane when it’s time to unload.

Hotels

Bigger FBO’s may have discounted rates with local hotels. If you call the desk and explain your needs they may offer to book it for you, or at least point you in the right direction. It may be worth picking an airport with more expensive fuel if it puts you closer to the hotels or restaurants you want to go to.

Night Flying

ByHank Gibson October 16, 2018October 16, 2018

Ah, fall is finally here.  In Texas, it arrived about a month late, but showed up with a vengeance.  A strong cold front caused a 40 degree temperature drop in 12 hours earlier this week, bringing rain, lower freezing levels, and lots of wind.

Fall means cooler temps, but fall also means less light.  The sun begins to set sooner, plus the fall back time change in November cause darkness to spring upon an unaware pilot.

Before getting in to too many night landings tips, just a friendly reminder, passengers can only be carried at night if the PIC has completed 3 takeoffs and landings to a full stop in the last 90 days during the time period of 1 hour after sunset to 1 hour before sunrise.

Lots of us have been landing long before sunset for most of the past couple of months, so those night flying skills might be a little rusty.  The best way to remedy night flying rustiness?  Call an instructor and go get some practice.

In the meantime, here are some tips as to what to expect for your next night flying experience.

1. Your Eyes Are Very Important.  This may seem like an obvious statement, but night vision can be affected by many things.  Before you takeoff, you want to make sure you can see in the dark.  The FAA recommends no bright lights 30 minutes prior to takeoff.  They also recommend using oxygen at night as this greatly improves night vision, even at low altitudes.  Use off center viewing to help spot traffic or other objects in the air.  Finally, when preflighting, use a red flashlight as much as possible, but if you do have to use a white light, close one eye to keep one eye from being blinded.
2. Utilize Approach Lights on Landing.  Night landings are very different then day landings.  It is very difficult to get the proper depth perception, not too mention see obstacles below you on your final approach to a runway.  PAPI’s, VASI’s, and instrument approach glide slope’s become very important.  If you are VFR only pilot, if your airport has a PAPI or a VASI, keep 2 white and 2 red (or 1 white and 1 red) lights.  If you see 3 red (or 2 red), climb.  If you see 4 red, definitely climb.  If you are an IFR pilot, I highly recommend always flying an approach at night.  What if your airport doesn’t have a PAPI, VASI, or approach with a glide slope?  You might not want to utilize it at night.  One side note on VFR flight: Clouds are nearly invisible at night.  If you do fly into a cloud (a clue is your strobe lights start reflecting back at you), don’t panic.  If you have an autopilot, turn it on and execute a 180 degree level turn.  If you don’t have an autopilot, start scanning your instruments, keep your attitude indicator blue side up, and make a shallow 180 degree while maintaining altitude.  Then call ATC, advise them what happened, and ask for help.  One more note:  I highly recommend that if a pilot finds that he/she will fly at night at lot, get an instrument rating and fly IFR at night.  It’s much safer.
3. Practice Landings Before Carrying Passengers.  The tendency when landing at night is to level off too high before flaring, causing the airplane to bleed off speed and energy too high above the runway.  This can lead to a stall, a hard landing, and/or too high of a pitch attitude at touch down causing a tail strike. A good tip is start your level off when you can see the tire marks on the runway.  Make sure you practice night landings, preferably with an experienced instructor who is night current and proficient, before carrying any passengers on board, even if you are night current, but haven’t landed at night in a while.
4. Night Emergencies.  For engine failures at night, you are very limited on options.  Unless you have a Cirrus equipped with a CAPS parachute system, you really have two options if an airport isn’t within gliding distance.  Find a wide, lighted road that appears to be lightly trafficked.  A word of caution, though:  be careful of light poles, fences, concrete medians, cars, and buildings.  The LA freeway would not be a good option (though there are exceptions to this rule as is evidenced by the picture below).  The second option is find a dark spot and pray it’s a field (or the Hudson River).  As you get closer, you can turn your landing light on to see what the ground looks like.  If it looks good, keep the light on and continue.  If you don’t like what you see, turn your landing light off and continue….

Flying at night can be the best time of day to fly.  It’s usually smoother, cooler, and you get to see all the city lights.  It is a very different environment, however, so make sure to get some training before darkness settles in on your next trip.
