Winter Ops

ByAndrew Robinson August 10, 2015August 19, 2015

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.

 

 

• 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.

Fly Away Destination: Sedona, AZ (KSEZ)

ByHank Gibson October 21, 2014October 21, 2014

Looking for somewhere to take a trip this fall?  Sedona, Arizona should warrant strong consideration.  Just shy of 100 miles north of Phoenix, Sedona is one of the most beautiful areas in the southwest United States.  From Texas, depending on how fast your airplane travels, you could make it to Sedona in a day, with a couple of stops in between.  You’d definitely want to spend a few days to enjoy the scenery and maybe jump over to the Grand Canyon while you’re in the area.

The Airport

As you approach the Sedona Airport (KSEZ), you become somewhat distracted by the scenery around you.  Don’t be too distracted as the approach is a little tricky.  If you are landing north, on Runway 3, the calm wind runway, don’t let the surroundings fool you.  Stay on that PAPI and don’t be short, as the runway is on a 500 foot mesa.  In instrument conditions, the MDA for the RNAV approach to Runway 3 dumps you out about 1,300 feet above the airport elevation, giving you plenty of time to set up to land.

When using runway 21, don’t make your pattern too wide as there are some pretty tall rocks (around 7,000 feet) north of the field.  The Airport/Facilities Directory gives a warning to pilots in strong southwesterly wind conditions.  Be aware of strong downdrafts coming in on final for runway 21.

The runway itself is in excellent condition, and plenty long at just over 5,000 feet.  The FBO is a little dated, but the folks there are great.  They were redoing the ramp this summer, so beware of that.  Airplane parking is no problem, but actually getting to the FBO is a little tricky.  The Mesa Grill is a very nice good restaurant just a short walk from the FBO.  When I was there, I chowed down on a buffalo burger.  It definitely hit the spot.

What To Do

Sedona is the outdoorsman’s paradise.  Starting off, to get a great overview of the area, hop on the Red Rock Scenic Byway (SR 179) about an hour before dusk.  You’ll get to see some spectacular views while it’s still light, then you can’t beat the sunsets in Sedona.

For hiking, you have a myriad of options, from the Cathedral Rock, to the Oak Creek Canyon, to the Devil’s Bridge Trail, all are beautiful, though most are not for the faint of heart (especially the Devil’s Bridge).  Even though the fall is cooler, make sure you pack plenty of water for the hikes.

Want something to do in the evening?  Go up to the Chapel of the Holy Cross to watch the sunset.  After the sun goes down, go do some stargazing.  You’ll get to take a tour of the stars at the Sedona Star Gazing location in Oak Creek.  You are shown all the constellations and stars by professional astronomers, and blankets and chairs are provided.

Art connoisseur?  You’ll find plenty of art galleries around town with a ton of beautiful, original artwork.  There are also several theaters and golf courses around Sedona, giving everyone a little bit of everything.

If you’re up for it, the Grand Canyon is about a 2 hour drive north of Sedona, or a quick flight up to the Grand Canyon Airport (KGCN).

In search of a good getaway?  Try Sedona.  You’ll be sore from lots of hiking and sight seeing, but it will definitely have been worth it.

PIREP: Austin Bergstrom Recovering After Flood Damage

ByHank Gibson November 5, 2015

The massive storms that rolled through the Austin Bergstrom and San Antonio areas last Friday not only put a dent in the landscape, they put a dent in the skies too.

The Austin Bergstrom (KAUS) control tower suffered significant flood damage Friday.  6 inches of rainfall in an hour caused water to come pouring into the first floor of the tower, flooding the radar room and knocking out the power.  This led to transmission outages for the tower, ground control, clearance delivery and the ATIS.  Similar to the Chicago Center fire last year (though this was a much smaller section of airspace), the area normally controlled by Austin Approach was replaced by a big, gaping radar hole.

By 8:45am on Friday morning, the Austin Bergstrom airport actually closed.  One runway eventually opened back up Friday afternoon, but massive delays and cancellations had already taken place.  All the ILS approaches were down and Houston Center had taken over the airspace normally occupied by Austin Approach control.

A temporary, emergency tower vehicle was brought in by the FAA (it’s essentially an RV with communications and a giant window) by the end of the weekend.  All arrivals and departures were restricted to 17L and 35R.

Due to the radar outage, I heard there was as much as a 4 hour delay even for planes coming into Austin Bergstrom from Dallas, and that was in VMC conditions on Sunday and Monday.  Tuesday and Wednesday brought IMC conditions which only enhanced the delays.

The latest news is that Austin Approach will be opening back up, but in a satellite base in San Antonio.  The Austin controllers will be using the SAT radar room and will be receiving their radar picture via satellite.  The approach frequencies should be up and running today or tomorrow.  The Austin Bergstrom tower is up and running and most of the ILS approaches are operational at this point.

In the meantime, expect delays going in and out of Austin.  If you don’t have to get to AUS, EDC, or GTU, you’re better off delaying a day or two until Austin Approach is back up and running.

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!

Texas Top Aviation at the AOPA Fly-In

ByHank Gibson May 9, 2014

Where were you on April 26th?

Texas Top Aviation was at the AOPA Regional Fly-In at the San Marcos Regional Airport (KHYI).  If you weren’t there, you certainly missed out spending time with 2,500 other airplane and flying enthusiasts!

The day began somewhat gloomy and windy with the threat of rain.  Organizers feared that weather would keep a lot of people from coming.  Boy, were they wrong!

There were many classic airplanes, many modern and pretty nicely equipped airplanes, and everything in between.  There were aviation celebrities, Rod Machado and the Kings of King Schools fame, to name a few.  Not to mention the fabulous BBQ!

Texas Top Aviation had several drawings for free training and 3 lucky winners.  We also had a Lancair Super ES for sale, N132BB (which made the San Marcos Record newspaper!). It definitely stood out with it’s unique paint job.  The flames on the tail drew many oohs and aahs.

Departing the San Marcos Airport after the fly in was like battling traffic in Austin at rush hour (though, Austin doesn’t have any air traffic controllers).  The San Marcos controllers probably hadn’t seen that much traffic since the airport was an Army Air Base back during WWII.  It was quite a sight to see all the exhibitor’s airplanes lined up ready to head skyward.

Thanks to all of you who stopped by the Texas Top Aviation booth!  It was a pleasure meeting all of you and we look forward to working with you in the future!

 

Reading Weather Prog Charts

ByHank Gibson January 27, 2015July 14, 2026

There are a multitude of weather products out there today to assist pilots in preparing for a flight.  Aviationweather.gov is the best source for getting all the information a pilot needs for planning a flight.  Aviationweather.gov is the National Weather Service’s source for all aviation related weather products.  When I teach about weather and weather briefings, I recommend to my students to utilize Aviationweather.gov in the planning stages, but still call the Flight Service Station to get a full fledged weather briefing before takeoff.

When preflight weather planning, one of the best ways to get a picture of what is happening over a broad area is utilizing the Low Level Significant Weather Prog charts.  The Prog chart gives a forecasted 12 and 24 hour picture of what type of weather to expect over the US.  The Prog chart gives the expected flight rules, areas of turbulence, and where the freezing level is located.  If you’re looking at the 4 panel view, the Surface Prog chart shows fronts, pressure areas, and areas of expected precipitation.  That covers just about everything, doesn’t it?

I believe the Prog charts are underutilized in planning.  Foreflight and Garmin Pilot have given easy access to radar pictures, satellite pictures, METARs, TAFs, and several other sources of weather information.  But, a lot of the easy access data you can get from those apps is current data (with the exception of the TAF) while a lot of the forecast data takes some hunting around.  So, products like Prog charts aren’t often utilized.

The other problem arises when pilots know about Prog charts, but don’t know how to read them, then don’t know how to find the legend to decipher the chart, the chart is often set aside and quickly forgotten about just because of a lack of knowledge.  Have no fear, though, as now we will use an example 4 panel Prog chart to decipher the lines and colorations.

Just looking at the Low Level Significant Weather Prog Chart above, it can be a little confusing.  That’s why they make a legend!

Coupling the legend with the chart above, we can determine some things.  First, California, parts of the Pacific Northwest, a small part of southern Arizona, and a good portion of the Midwest and East coast are going to have marginal VFR conditions in the next 12 hours.  Wisconsin, Illinois, a good portion of the Northeast, and a small portion of the Pacific Northwest will suffer IFR from IFR conditions.  There are going to be a good amount of low level turbulence in the northern and eastern parts of the country.  Finally, the freezing level starts at the surface running in a jagged line across the midwest states and curling up into the Northeast.

That’s a good bit of information, isn’t it?  If a pilot is planning a VFR flight into the Northeast tonight, it would probably be best to wait for another day, according to this chart.

Now, to see what is causing the conditions above, we need to look at the Surface Prog Chart.

The green circular areas above show that some form of precipitation is in that area.  The circular dots with the triangle located in Mexico and Baja California are depicting moderate rain showers.  If the triangle was gone, it would just be moderate rain.  In the northeast, all those symbols are showing moderate to heavy snow showers.  Across the plains, we see a lot of high pressure, meaning visibility and nice flying weather.

These charts are invaluable when it comes to flight planning, especially over long distances when the weather could be changing a lot over the period of your flight.  Put them to use the next time you are planning a trip and you’ll learn you have a much better picture of what the weather is doing.
