After Market Ice Protection

It’s winter time, so that means winter weather for the aviation community.  For single engine piston pilots, that means dealing with icing conditions.  For us Texan flyers, ice only presents an issue for maybe a week out of the year (the exception being for those Panhandle residents!), but it’s nice to have some protection.

Most single engine pistons do not come with ice protection from the factory and, of those that do, most are not Flight Into Known Icing (FIKI) approved.  The systems are “get out of jail” systems that can reduce the amount of ice you pick up if you accidentally get into icing conditions and you are on your way out.  The Cirrus SR22 line of aircraft has had the TKS system option since 2006, with the new FIKI system being available since 2010.  The Cessna TTx has a FIKI option that was debuted in 2014.

The above mentioned airplanes use TKS systems.  There are a handful of single engine pistons that use boots that are FIKI certified:  the Piper PA46 line (Malibu, Mirage, and Matrix) and the Cessna P210 and T210 line (though not all are equipped with boots).

If you find yourself flying into wintry conditions often and want some protection for your clean wing airplane, there are some aftermarket options for a lot of airplanes now.  Do note that all these systems do come with a pretty hefty price tag, but can be worth it if you fly into icing a good bit.

CAV Ice Protection TKS Systems

CAV Ice Protection is a TKS system outfitter.  What is TKS fluid?  According to Flying Magazine:

“TKS systems dispense an ethylene glycol-based fluid with a freezing point below minus 70 degrees F through porous titanium panels attached to the leading edge of the wing and empennage. The fluid is released through thousands of the panels’ laser-drilled holes, which are not much larger than the size of a human hair. As air flows over the wing and empennage, it disperses the fluid, coating the surfaces, and preventing the formation and adherence of ice.”

The advantages of a TKS system are the whole entire wing gets coated to get rid of any extra ice that adheres to the top or bottom of the wing surface.  The disadvantage is there is only a finite amount of fluid, so when it runs out, you don’t have any more protection.  The fluid also adds extra weight agains the useful load of the airplane.

CAV Offers a Basic TKS system for the following single engine piston aircraft:

  • Beech Bonanza
  • Cessna 182, 206, 210, 350, & 400
  • Columbia 350 & 400
  • Piper PA32
  • Mooney M20

CAV Offers a full FIKI System for the following single engine piston aircraft:

  • Beech A36 & G36 Bonanza, and Baron
  • Cessna 210 & TTx
  • Commander 114
  • Mooney M20

Ice Shield De-Icing Boots

Ice Shield is another after market de-ice option.  Ice Shield makes boots for wing leading edges.  The advantage of boots is they activate instantaneously, getting rid of ice where it builds up first, on the wing leading edge.  No running out of fluid and only the added weight of the system.  Ice Shield also offers heated windscreens for several the Piper Saratoga line and the A36, B36, and G36 Bonanza line.

Ice Shield has boots for the following single engine piston aircraft:

  • Beech Bonanza F33A and -36 line
  • Cessna 210 line
  • Piper Pa46 line

For more information, check out Ice Shield’s Website.

One other company, Kelly Aerospace, makes an electric leading edge de-icer called the ThermaWing for the Cessna/Columbia 350/400 line.  You can read a review of the ThermaWing here, or check out Kelly Aerospace’s website.

  • Shock Cooling in a PA46

    We’ve all heard it said…”reduce the throttle by no more than 1-inch every minutes to ensure you don’t shock-cool your engine”. Does this advice apply to a PA46 engine? Can a PA46 engine (Lycoming 540 or Continental 520/550) really be shock-cooled? How should the engine temperature be managed?

    Metals expand and contract with temperature, and the various metals in an air-cooled aviation engine expand and contract at a different rates. Shock-cooling supposedly occurs when the engine changes temperature quickly and the different metals in the engine cool (and therefore change shape) at different rates. When the change occurs dramatically supposed scoring, rubbing, and marking of the metal can occur, which can cause catastrophic results.

    So, let’s back to the original question…can a PA46 engine suffer shock-cooling and should a pilot operate the engine so as to avoid shock cooling? Simply put, I’ve never seen nor heard of any piston PA46 engine suffer shock-cooling. In 5000+ hours flying the piston PA46 and 16 years of flying/managing/training in the Malibu/Mirage/Matrix, it simply has not happened to me nor anyone I know. Does it mean that it cannot happen or has never happened? No. But, it is certainly not a prolific threat to our fleet.

    Should the owner/pilot operate the engine with a cautious eye cast toward the potential of shock cooling? Well, sort of…but, let’s flesh this out. My suggestion is that a pilot should operate the engine with conservatism in movement of temperature, but only because this is a good operating practice with any machine, and any flying machine is (by definition) not “overbuilt”. And, there are many ways to change the temperature of the engine…not just by reducing power. Here’s a partial list of ways to cool your PA46 engine:

    • Reduce power: Obvious…yes. When the engine produces less power, less heat is generated. Reducing power in a piston engine will almost always result in less temperature.
    • Lower the nose: By descending (and leaving power in a cruise setting) the airspeed will increase and cool the engine.
    • Enrichen the mixture: Fuel has a cooling effect on the engine, so the richer the mixture the cooler the engine.
    • Lower the landing gear: Yes…you read that right…engine cooling will occur when you lower the landing gear because more air will flow over the cylinders. Notice the landing gear doors on the PA46 have air louvers. Air flows into the engine nacelle on the front, passes down through the cylinders (along with the oil cooler, intercoolers, and other components) and then out the louvers of the closed gear doors. When the landing gear is lowered the “back door is opened” and a LOT more airflows over the cylinders.

    My suggestion is that a pilot only perform ONE of these actions at a time when beginning a descent. This suggestion was presented to me by Chad Menne (Owner, Malibu Aerospace) some time ago and I’ve operated engines this way ever since. If you are at a higher altitude and simultaneously reduced the power, lowered the landing gear, started a big descent, and enrichened the mixture in one flail swoop, I think there’s a chance that your engine would suffer some negative effects that could be called “shock cooling”. So, when you do start a descent, pick one “cooling action” to accomplish at a time. I’m sure you’ll not hurt your engine.

    Simply put, shock cooling is not a huge factor in the PA46 community, and a PA46 pilot does not need to be overly cautious. The “one inch per minute” rule may apply in some other airframes, but in the PA46 world it is not applicable.

    Joe Casey’s aviation story began in 1990 with his first flight near Nacogdoches, TX in a Cessna 172. From lift-off, Joe knew he would have a lifetime passion flying just about anything that will leave the ground…He was completely hooked.

    Along with being an FAA Designated Pilot Examiner (DPE), Joe is an ATP/CFI-AHMG and Commercial Rotorcraft/Glider Pilot in the civilian world and also a UH-60/AH-64 Pilot-in-Command/Instructor/Examiner Pilot in the US Army Reserves.  His passion for the last 19 years, however, has been the PA-46 Malibu/Mirage/Matrix/Jetprop/Meridian. Has has amassed over 6,500 hours in various PA-46 airframes and believe it to be one of the finest flying machines available for the serious cross-country pilot with an eye for efficiency.

    Now, Joe has flown more than 12,200 hours in just about every imaginable environment. Whether providing initial/recurrent training in the PA-46’s, TBM’s, instructing in NVG’s in a UH-60 Blackhawk, flying the King Air series of airplanes, giving tailwheel endorsements, or taking kids flying for the first time, he simply loves flying machines and the people who fly them.

  • Garmin VNV

    The Garmin G1000/Perspective combined with the Garmin GFC 700 Autopilot can be a great tool in descent planning.  When you want to end up at pattern altitude a certain distance from the airport or you get a clearance to cross a fix at a certain altitude, Garmin VNV is a great tool.  Here’s how to use it.

    VFR Garmin VNV Use

    Let’s say you want to end up at pattern altitude 3nm from your destination, but you don’t want to descend down into the bumps before you have to.  Here’s how to set it up:

    • Go to the Flight Plan page on the MFD
    • Press the ATK OFST soft key on the bottom of the MFD.  It stands for Along Track Offset, which, in laymen’s terms, means you are setting a point along your track a certain distance from your destination.  In this case, it will be 3nm
    • Input the distance using either the keypad or the small FMS knob and press enter
    • Select the altitude you want to be at (in this case pattern altitude) and press enter
    • You will see a point 3nm before you destination appear on your magenta line and a Top Of Descent (TOD) appear where you need to start your descent
    • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
    • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
      • Set the Altitude bug for the desired altitude
      • Press VNV on the autopilot
    • All you have to do now is manage power

    IFR Garmin VNV Use

    Let’s say you are told to cross a fix at a specific altitude.  Here’s how to use Garmin VNV to plan it out.

    • Go to the Flight Plan page on the MFD
    • Turn the cursor on and highlight the altitude blank next to the fix in the flight plan
    • Input the desired altitude
    • You will see a Top Of Descent (TOD) point appear along your course where you need to start your descent
    • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
    • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
      • Set the Altitude bug for the desired altitude
      • Press VNV on the autopilot
    • All you have to do now is manage power
  • Beechcraft Flap Issues

    There has always been something that felt wrong to me about how the walkway on many models of Beechcraft extends onto the right hand flap. I have never felt right about stepping onto the flap as I make my way into and out of my dad’s E33A Bonanza and therefore I generally try to step over top of it and place my foot on the wing instead. But does this effort actually make any difference, or am I just making my self look silly for no reason?

    Nutplate Cracking 3

    Well, as it turns out, it wasn’t such a bad idea. In 2007, a pilot flying a Beech reported a split flap condition. Upon inspection, it was found that there was damage to the actuation rod attachment as well as the nose rib and nut plates. Six other aircraft were checked and found to have similar damage. These findings were submitted to Hawker Beechcraft and in 2008 and they issued a maintenance alert regarding the issue. In 2011 the FAA issued SAIB CE-11-21 (Special Airworthiness Information Bulletin) to alert owners, operators, and maintenance personnel about the problem; specifically warning of the potential for cracking in the nose flap rib (part number 35-165050-84). And while its true that this type of damage is not limited to the right hand flap, it is known to be much more common on that side. Stepping over the flap instead of on it is recommended by both the FAA and Beechcraft as a solution.

    Unfortunately, the flap cracking is known to span a wide variety of aircraft types. A 2011 “Safety Communique” issued by Hawker Beechcraft lists the affected models as:

    -Bonanza 33, 35, and 36
    -Baron 55, 56, 58, and 95
    -Duke 60

    According the the FAA, the cracking can been found most commonly on airframes which are between 4,000 and 6,500 hours, but has also been found on aircraft with as few as 2,000.

    So, what do we do about it?

    First off, although much of the damage is difficult to detect without dis-assembly, the paperwork from both the FAA and Beechcraft recommend taking a look at the flap yourself to see if there are any obvious signs of problems. They also suggest taking special care looking in this area during your preflight inspections.

    Next, if you have an airplane which may be susceptible to cracking, talk to who ever is doing your maintenance work and have them look carefully during your annual inspections. I talked to one of the IA’s at our shop who has dealt with this issue before and he told me that most shops will remove the flap and send it away to a repair station to have it fixed. It’s possible that if you purchased your airplane used it may have already had this issue taken care of; a quick look through the maintenance logbooks should clear up any questions.

    Regardless of whether your airplane is known to suffer from this problem or not, do your best to avoid stepping on the flap when getting in and out of the cockpit. It is also a good idea to ask your passengers to do the same as this simple act could end up saving you big headaches and big money someday down the road.

  • Landing Light Replacement

    One evening this summer, my wife and I were flying down the southern shore of Long Island in my father’s E33 Bonanza. We enjoyed the sunset as we flew westbound and our plan was to fly the New York Hudson corridor, where we would arrive just after dark. As we approached New York’s airspace, two voices in my head started having a debate.

    The first voice said: “You should turn on your landing light when you get to New York to make the airplane more visible.”

    The other voice said: “That’s true, but I bet you’ll burn the landing light out”

    Well, as it turned out, both voices were right. My landing light fired right up when I needed it to fly the Hudson, but when it came time to land back home I had no such luck. Unfortunately, this was not the first time that I had been given the chance to practice my blackout landings. This Bonanza model has only one landing/ taxi light which is mounted in the lower cowling behind the propeller. This location is less than ideal because the filament in the bulb is fragile and can be damaged by engine vibration.

    We landed uneventfully and after putting the airplane away, I decided it was time to look into upgrading the lighting to something a little more modern. I was unsure of my options, but seeing as the airplane needed a replacement bulb regardless, it seemed like a good opportunity to make a change.

    After doing a little reading, I learned that HID or LED landing lights would be the best solution to my problem. I was familiar with LED aircraft lights, but had never heard of HID before.

    Here is what I learned:

    HID Landing Lights

    HID, or High Intensity Discharge landing lights, create light by arcing electricity through a sealed gas capsule. They are brighter than LED and traditional incandescent, and the light created more closely resembles the look and feel of sunlight. HID installations require a ballast to carefully regulate the flow of electricity to the gas capsule and also require a “warm up” period after being turned on in order to reach their full brightness.

    Fitting an aircraft with HID landing lights tends to be more expensive and time consuming than installing an LED light and would likely require involvement by an A&P/ IA. However, if you want the brightest light available, HID is probably the best bet.

    Pros

    • Brighter, more natural looking light
    • Draws less power than standard bulbs
    • Long bulb life
    • Does not generate much heat

    Cons

    • More expensive than other lighting options
    • Lights must “warm up” after being turned on
    • Cannot be pulsed easily
    • Cost/complexity of installations

    LED Landing Lights

    LED, or Light Emitting Diode landing lights, have no filament and work by moving electricity through diodes which are connected into a circuit. These lights have become very popular for many uses due to their simplicity, low cost, and brightness.

    While not as bright as HID light, the LED lights require no “warm up period” and can be easily pulsed. LED lights draw much less power from the aircraft’s electrical system than traditional bulbs and boast incredible life length. LED bulb installation is very simple and can often serve as a direct replacement for the original lights.

    Pros

    • Instant light (no warm up)
    • Incredible life length (>5,000 hours)
    • Low Cost
    • Simplicity of installation
    • Can be pulsed easily
    • Low power draw

    Cons

    • Not as bright as HID lighting

     

    After weighing the options, I decided to replace the incandescent bulb in the Bonanza with an LED bulb. I read the reviews online and talked to some of my friends who work in aviation and eventually decided on the Lycoming Alphabeam. The Alphabeam is FAA/PMA approved and is available through Aircraft Spruce and other aviation parts vendors. The bulb cost around 250-300 dollars and I was able to install it as a direct replacement for our old light. All I had to do was take the old one out, put the new one in, and make a logbook entry.

    Below are some pictures of the installation:

    Last weekend I finally had an opportunity to take the airplane out after dark and see how the new light compared to the old one. I am pleased to say that it did a wonderful job and exceeded my expectations.

    If you are interested in seeing a side by side comparison of the different lighting options, a quick Google search should provide what you are looking for. In my own experience, I would say that the LED light was brighter than the old light and did a very good job illuminating the taxiway and runway. It was extremely nice not to be concerned that my light wouldn’t work as I was setting up for landing at an unfamiliar field after dark. I also enjoyed feeling that I had the option to leave it on during climb and cruise in order to increase my visibility to other aircraft.

    Many models of aircraft have multiple landing/ taxi lights installed which greatly reduces the likelihood of having to land without one. In our case, spending the extra money to upgrade to the LED bulb made sense because of the desire for increased reliability. If you are looking for a relatively inexpensive way to upgrade your airplane, LED or HID lighting may be something to consider.
