Lightspeed Zulu 2 vs. The Bose A20

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

Bose A20

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

Lightspeed Zulu 2

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.

  • Garmin GFC 700 Autopilot

    The Garmin GFC 700 Autopilot is an amazing machine.  Fully digital and fully integrated with the Garmin G1000 glass panel, it makes a pilot’s workload a lot easier, especially in busy airspace.

    I train a lot of pilots in airplanes that have the Garmin GFC 700 autopilot.  The Cirrus SR22, the Columbia 350 & 400, the G36 Bonanza, and the Piper Mirage and M350 to name a few.  The most common problem I see for pilots transitioning into the Garmin GFC 700 equipped aircraft is that it doesn’t act like other autopilots.

    STECs and DFC 90 Autopilots function like this:  you push the button for the mode you want on the autopilot controller and that turns the autopilot on.

    Not so on the Garmin GFC 700.  If you push the button for the mode on the GFC 700, then the flight director engages, but not the autopilot.  This confuses folks a lot who move up from different autopilots because their autopilot primacy side of their brain is telling them the autopilot is on whenever they push one of the buttons on the GFC 700 controller.

    Here’s an example:  A pilot has just departed and is ready to turn on course.  In his old airplane with an STEC 55x autopilot, the pilot pushes the direct to key to go to his first waypoint, then pushes NAV on the autopilot controller and the STEC 55x comes on and starts flying on course.  Then he presses VS and ALT to initiate a climb.

    With the same scenario and a Garmin GFC 700 autopilot, the same pilot (who is used to a 55x), pushes the direct to key, then pushes NAV on the autopilot controller and pushes IAS or FLC to initiate the climb.  He lets go of the flight controls thinking the autopilot is engaged.  The airplane starts nosing over and he starts panicking.

    Why did this happen?  The pilot in the second scenario never pushed the AP button on the Garmin GFC 700 so the autopilot never engaged.  All he did by pressing the NAV button and IAS button was to turn the flight director on.

    How to remedy this?  Get in the habit of checking your scoreboard.  On the top of the G1000 or Garmin Perspective PFD, there is an autopilot annunciation strip (or scoreboard as I like to call it).  In the very middle of the scoreboard is an area to show if the autopilot or flight director is engaged.  AP means the autopilot is on; FD means the flight director is engaged but the autopilot is not.

    I teach pilots to be in the habit of checking your scoreboard each time you get done pressing buttons on the autopilot controller to ensure the Garmin GFC 700 is in the proper mode.  This saves some of those panic moments when it is supposed the AP is engaged, but it’s only the FD.

  • Winter Ops

    It’s summertime and the weather is hot! Over this dry, sunny season, winter flying is probably the last thing on your mind. However, now is the perfect time to start getting things in place for winter and that includes having a plan for taking care of your airplane.

    Why are preparations for winter ops needed in the first place? Cold weather, especially during the engine start and warm up period, can be very damaging to your engine if precautions aren’t taken to ensure that safe temperatures exist inside the engine before you turn the key. I always thought that the biggest problem associated with cold weather was engine oil. The logic is since cold oil is thicker and less viscous as the temperature drops, it is not able to circulate quickly throughout the engine to provide proper lubrication upon starting.

    While cold oil may be a factor, the introduction of multi­viscocity oils has greatly reduced that issue. The real problem is created by the different ways that various parts of the engine respond to heat. Because aluminum expands more quickly when heated than steel does, the pistons (made of aluminum) expand more quickly than the cylinders (made of steel). This can lead to scuffing on the sides of the cylinder barrel. In the same way, differential heating can reduce clearances which are designed to provide cooling oil to bearings and other vital engine parts, thereby causing damage which greatly reduces the life of the engine.

    So how cold is TOO cold? Unfortunately, that is a difficult question to answer. Because there is so much variation between engines, airplanes, and environments, there really isn’t any one specific answer. An older, more worn out engine may actually be less susceptible to cold weather damage than a newer, tighter engine because its internal clearances are probably not as tight as they were a few thousand hours ago. I have heard of some people who preheat their airplanes anytime the temperature falls below about 40 degrees. For us northerners, this seems excessive. On our E33A Bonanza which has a Continental IO­520, we generally preheat the airplane when it is cold soaked in temperatures below freezing (32° F).

    Here are a few of the best ways to get your machine ready for a cold weather flight:

    • Heated Hangar:­ Nothing beats a heated hangar for warming up an airplane. The warm air is evenly distributed around the engine and in the cockpit (your avionics and gyros will thank you!). The airplane will need to be in the hangar for a while in order to warm up the guts of the engine. Often, the easiest way is to have the airplane pulled in the evening before the planned departure and left overnight. Many FBOs will hangar airplanes overnight for a small fee and it is well worth the price. We almost always have our charter airplanes put into hangars overnight when on a winter trip to ensure that we don’t have any trouble when we depart the next day. This practice has the added benefit of keeping the airframe clear of any ice and snow that may accumulate before you are scheduled to leave.
    • Electric Engine Heaters­: Multi­point electronic heaters use heating pads that are placed around the engine in order to heat up the various components such as cylinders, the oil pan and crankcase. Most of these systems are designed to be activated by being plugged into a wall outlet with an extension cord. Preheating for a winter flight is as simple as going to the airport the night before and plugging it in. Two well ­known manufacturers of multi­point engine heaters are Reiff and Tanis. These systems are relatively inexpensive and can be a life saver if you regularly travel in colder climates. If an engine heater is the right choice for you, it is recommended to avoid less ­expensive models that heat only the oil pan.

    • Covers and Blankets­: If it is especially cold or you have to preheat outside, having something to insulate the cowling and keep the wind out can be very useful. Regular blankets will work long as you can secure them in place. If you have an ongoing need for additional insulation, there are companies that make custom blankets and propeller covers to fit your airplane. If you are landing and then taking off again relatively quickly, using a few blankets and cowl plugs will work nicely to keep the engine warm while it is sitting outside. In a pinch, placing a couple of powered light bulbs in the cowling overnight with insulation on top can result in sufficient temperatures for starting the engine.

     

    Bonanza Cover
    Even with the multi­point electric heater, we still use a blanket while preheating to help keep everything toasty.

     

    • Forced Air:­ This method is used widely by FBO’s and flight schools. Hot air is produced in a portable heater and is then pumped into the engine compartment via the openings at the front or bottom of the cowling. This method has the benefit of not requiring any additional equipment to be installed on the aircraft beforehand and can be very effective provided there is adequate time for the engine to heat completely before removal.

    • Winter Baffles:­ When the air temperature starts to drop into the teens and lower, you may find it difficult to keep your engine temperatures warm enough in cruise flight. The problem is that the air entering the cowling inlets is so cold that it overcools the engine. The solution is to install additional baffling in the engine inlets to reduce the amount of airflow into the cowling. These additional baffles are usually just sheets of aluminum that are cut to the correct size and are bolted in and removed quickly and easily as needed. Some pilots swear by them while others complain that they can cause uneven cooling. If you have questions about winter baffling, I’d suggest talking to your mechanic about your specific airplane.

    Winter flying can be extremely rewarding. After their hands thaw from pre­flight, a pilot is often rewarded with smooth air, improved performance and outstanding views. Just don’t forget to prepare the airplane for the cold. The preparation is often as simple as plugging in an extension cord or making a phone call to the FBO. So whether you live in the north or the south, take good care of your engine so that it can keep taking good care of you.

  • Present Position Hold

    When I was working on my instrument rating back in 2007, my instructor and I did a lot of unpublished holds.  In ground school, I heard a lot about holding for weather or holding due to a traffic delay.  At my first job, my chief flight instructor was also a Continental (now United) captain and he told me a lot about having to hold for weather going into different places.

    I heard all this, but I figured it would never happen to me when I’m flying GA airplanes.

    Boy was I wrong!

    I was flying a Piper Malibu into Phoenix with two passengers for Super Bowl weekend and the weather was awful.  No thunderstorms, but moderate precipitation and low ceilings.  We were coming into Deer Valley (KDVT) on the north side of Phoenix and about an hour out, ATC advised me that arrivals into DVT were having to hold and to expect a delay.  The controller said the delay would be about 30 minutes, so by doing a quick calculation, I determined the delay would probably be all cleared up by the time I got in the area.  At the time, I didn’t know if the delay was due to weather or traffic congestion.

    Twenty minutes later, the controller advised me that there was still a delay.  I queried what it was for and he informed me it was due to weather.  He asked me if I wanted to hold or divert.  I listened to the ATIS and heard the ceilings were variable from just below the minimums to just above.  I told him I would hold as the TAF I saw predicted the ceilings to go up.

    “Malibu, hold present position, hold east, expect further clearance 2140 Zulu.”  Gulp.

    At this point, my autopilot had gone out, it was turbulent and I was definitely in the soup.  This was going to be fun.

    After recovering my wits, I read back the clearance, then set about setting up this hold without getting too far from my present position.  The Malibu I was flying had a Garmin 530 which I was using as my primary means of navigation.  I was on V190, but I didn’t have all the fixes in my flight plan.  What to do?  And what to do fast?

    The 530 has a rarely used function called a User Waypoint.  It comes in handy in situations like these.  On the moving map, you can turn the cursor on, move the cursor to any point on the map, and, by pressing enter, create a User Waypoint.  This is what I did on V190.  After I created it, I had to go to my flight plan, find the right spot, and input the User Waypoint just like I would any fix.  Just a note here, when you create a User Waypoint, make sure you remember what you named it so you can find it again.

    After I input the User Waypoint in the flight plan, I had to go back and activate the leg that the User Waypoint was the end point on.  Then, to make sure the flight plan didn’t go to the next waypoint once I crossed my User Waypoint, I had to press the OBS button on the 530 in order to put the GPS in suspend mode.

    Keep in mind, my autopilot wasn’t working, so this involved a lot of multi-tasking!

    That’s how to do a present position hold using the Garmin 530.  Got all that?  Here’s a concise review:

    • Create a User Waypoint
      • Turn the cursor on by pressing the FMS knob
      • Move the cursor to the point where you want your User Waypoint
      • Press enter and name the User Waypoint
    • Press the Flight Plan button
    • Input the User Waypoint into your flight plan at the proper point
    • Activate the leg that the User Waypoint is the end point on
    • Finally, press the OBS button to put the GPS in suspend mode
    • After you’re cleared onward, just press the OBS button again to take the GPS out of suspend mode

  • Preventing Gear Up Landings

    On the evening of November 3rd, 2015, I was returning to my home airport of Lancaster from Pittsburgh in my company’s Aerostar, after being out on charter all day. It was dark out as I entered the traffic pattern at Lancaster. After an uneventful approach, I was cleared to land behind a Mooney. The spacing looked good as I turned final, but, as I was nearing the threshold, I started to become concerned that the Mooney wouldn’t be clear of the runway in time for me to land. At that moment, over the radio I heard an uncomfortable transmission from the Mooney pilot: “Tower, Mooney ABC has landed gear up.”

    It took the tower controller a minute to grasp what was going on, and I was on about a 1-2 mile final when I was instructed to go around. Thankfully, the Mooney came to a stop in such a position that I was able to use the other intersecting runway, and was on the ground only a few minutes later. I can assure you, however, that I’ve never checked my “3 green” so many times in one traffic pattern as after that incident. Thankfully, no one was hurt, but there sure was an impressive amount of emergency equipment on the runway as I taxied back to my hangar.

    In aviation, there’s a saying that goes: “There are two types of pilots. Those who have landed with their gear up, and those that will.” I don’t like that saying. The potential of a gear up landing (as a result of pilot error) is something that has always been a risk that I have worked hard to avoid. Not only is a gear up landing embarrassing; but it’s also an extremely expensive black mark on any pilot’s career.

    Not a good day. (Photo credit: http://www.newsday.com/long-island/suffolk/plane-lands-at-republic-with-no-wheels-1.2735131)

    According to a July 2006, article in Aviation Consumer, the estimated cost of repairs following a gear up landing for an A-36 Bonanza would be about $27,000 and about 3 weeks of down time. 25 years ago, even my beloved E33 Bonanza was the victim of a gear up landing. While it was neither me nor my dad flying our airplane that day, the event stays in its history and reduces its value should the time ever come to sell it.

    That incident in 1990 resulted in approximately $25,000-30,000 in repairs. The cause of the incident was classic: the pilot put the gear down at the normal time, but then had his downwind extended by tower. He brought the gear back up to fly the longer downwind, but forgot to put it back down later when he was cleared to land. Like many pilots, he had a set routine time when he normally put the gear down, and when his routine was changed, he didn’t remember to lower the gear once more.

    Unfortunately, no matter what experience level one may be at, no pilot is immune to the possibility of such a mistake. The following are 5 tips that I have learned in my time flying that have helped myself and others minimize the chance of a gear-up landing occurring:

    1. Know your aircraft systems: What are the operating perimeters on your airplane’s gear warning system? Most airplanes have a designated speed or power setting at which the gear warning horn will sound in the event that the gear isn’t down and locked. In the Aerostar that I was flying, the gear horn was supposed to come on at 15” of manifold pressure with the gear up, but in practice, it didn’t come on until much lower than that. It has since been adjusted, but at the time it was important for me to know that if I had left the gear up, the horn wouldn’t have sounded in a timely enough manner for me to go around, much less lower it prior to touchdown. Most likely it would have just added to the noise of metal on concrete as I pulled the power all the way back in the landing flare.
    2. Don’t override gear-up warning systems: They were put there for a reason! Even if you’re out doing maneuvers and the horn is blasting in your ear for half an hour, resist the temptation to simply pull the circuit breaker or push the warning silencer to make it shut up. If a pilot disables the gear-up warning horn and then later forgets to put the gear down on landing, he or she will have a much worse headache on their hands than the one that the horn would have given them.
    3. Use your checklists and memory items: It doesn’t matter how much a pilot knows about his or her airplane, or the procedures for it. Distractions happen. Mistakes Happen. Always consult the checklist for confirmation that you’ve accomplished all the essential tasks before landing. Additionally, if you haven’t already, work on developing call outs which you perform out loud regardless of whether you are alone in the airplane or not. Whenever I’m landing an airplane, I start with my flows, go through my GUMPS (Gas-Under carriage- mixture- props- seat belt) checks, then do the printed checklist, and finally when on short final I call out “short final, cleared to land, three green.” I’ve had several passengers tease me about doing the “three green” call out while I was flying aircraft that didn’t have retractable landing gear. But, I’d much rather be in the habit of checking every time regardless of what I’m flying than forgetting to check when it is necessary.
    4. Use your available resources and develop healthy habits: If I have someone riding with me, I generally ask them to confirm that there are 3 green lights glowing on the instrument panel. Even if that person isn’t a pilot, they will probably enjoy the opportunity to be involved, and it’s a good way for me to stay in the habit of checking the gear lights to ensure that everything is properly down and locked. I’ve also found that intentionally leaving your hand on the gear lever until you have gear safe lights is a good idea. Forcing yourself to keep your hand on the handle until you have the all important lights obligates you to actually observe the indications instead of simply throwing the lever and moving onto something else. This way, if you only get an indication of 2 greens you’ll be aware of it right away and have more time to respond appropriately. It also helps you to learn the normal length of time it takes for the gear to extend or retract, which will be helpful to you to be aware of any abnormalities in the gear system.
    5. Upgrade your aircraft’s gear-up warnings: There’s a variety of ways you can improve your aircraft’s ability to warn you of a potential gear-up landing. For student pilots or pilots new to complex aircraft, it could be something as simple as a red post-it note on the panel to remind you to verify the gear position prior to landing. Or, if you own an aircraft that doesn’t have an effective way to warn the pilot of a gear-up landing, consider investing in an aftermarket gear-up warning system – surely the extra price of such an upgrade is a small amount next to the cost of repairing the damage from a gear-up landing!

    Always remember, regardless of experience, no pilot is immune to the possibility of a gear up landing. The best way to safeguard yourself is to discipline yourself in the use of flows, checklists, and call outs. Things like gear warning horns, visual reminders, and other systems are a useful back up, but they shouldn’t be relied upon to save your bacon if you don’t get the gear down at the proper time. Fortunately, in most gear up landings, the pilot and passengers are able to walk away uninjured – but that doesn’t lessen the embarrassment or financial burden of the event. So, keep your chin up, your gear down, and remember….THREE GREEN

  • Cirrus Vision Jet Receives FAA Certification

    cirrus-vision-jet-interior

    The long anticipated certification of the Cirrus Vision Jet finally happened.  On October 30th, the FAA awarded certification to Cirrus’ single engine jet.  Marketed as the world’s first single engine personal jet, the Cirrus Vision Jet will seat five adults, two children, and cruise around 300 knots.

    The Williams FJ33-5A Turbo Fan engine is operated by a FADEC, single handle throttle, similar to the throttle in the piston powered Cirrus family.  In fact, the SR series was taken into consideration when designing the Cirrus Vision Jet in order to simplify the upgrade for pilots.  Many of the buttons and knobs are in the same places in the Cirrus Vision Jet.

    The Cirrus Vision Jet is equipped with the Cirrus Perspective Touch by Garmin that is very similar to the Cirrus Perspective by Garmin in the piston powered line.  Equipped also with the Flight Into Known Icing system and the Cirrus Airframe Parachute System (CAPS), both of which are standard.

    cirrus-perspective-touch

    Unlike the piston powered Cirrus lines, the CAPS system on the Cirrus Vision Jet is actually mounted in the nose.  Also, unlike the piston lines, the jet CAPS is integrated with the aircraft avionics to slow the airplane to between 67 and 160 knots when the system is activated.  In the jet, the CAPS system was designed to withstand higher weights, higher speeds and higher altitudes.

    Cirrus hopes to start deliveries of the Vision Jet by the end of the year, with many more rolling off the line in 2017.  All Cirrus Vision Jet pilots will need to be type rated in order to fly the aircraft.  Cirrus is doing all the type rating training in house at their new Vision Center in Knoxville, Tennessee.
