Thunderstorm Avoidance

ByHank Gibson January 19, 2016

Thunderstorms are not to be taken lightly. I know you have probably heard that many times in your flying career. Weather related accidents account for approximately 25% of airline and GA accidents.

The Airman’s Information Manual suggests giving a 20 mile berth around thunderstorms. If you are an experienced aviator or a newbie please take this piece of advice seriously. At one flight school where I taught, we had the policy of maintaining a 25 mile buffer around isolated thunderstorms. A bit excessive you think? Maybe, but safety is a good thing!

On this particular day, I was operating a Bell Jet Ranger helicopter during a power line patrol. Power line patrol by itself offers numerous challenges. The job consists of flying along electric power transmission lines at approximately 40 feet above the ground at 40 knots. The crew consisted of me (the pilot) and an observer. The observer is an employee of the power company and it is his job to determine which line(s) will be patrolled during the given day. As I fly along the lines, the observer is checking for anything out of the ordinary such as broken, cracked, or even shot out insulators, excessively large bird nests at the top of structures, or woodpecker holes in wooden poles. The observer knows the lines and he is also a great help in letting me know there is a crossing, and potentially higher, line in our flight path. That makes him a true safety asset!
It was late afternoon during the summer and we were about to finish up for the day. We only had about another 10 miles of line to follow before calling it a day. Up ahead, I noticed an isolated thunderstorm near our power line. I could see the heavy rain falling below the anvil shaped leading clouds. It appeared to be well beyond the end of our day’s work so we pressed on.

As we drew closer to the thunderstorm, we were suddenly tossed up on our left side like a dog toy in mid-flight! It seemed like we were 90 degrees to our normal cruise attitude and, to make it worse, we had the doors off on that hot summer day. I was able to recover and we did an immediate about face and high tailed it home. Forget the rest of that line, tomorrow is another day.

The destructive force of thunderstorms cannot be overstated. In addition to extremely heavy rain, they can contain strong wind shear, large hail, and severe turbulence, each of which can damage or destroy an aircraft. Take care when one of these bad boys is near your flight path. Give it plenty of respect and a lots of room, for safety’s sake.

Upgrading Avionics

ByHank Gibson October 6, 2014

There are many different ways to upgrade an instrument panel.  Putting in a 696 here, a JPI engine monitoring system there, even an Electronic HSI.  But, if you want to swing for the fences and get a serious upgrade, you have to go for a complete glass instrument panel.  For good measure, you might as well throw in a touch screen GPS while you are at it.

Which panel to go with?  There are two mainstream options (Garmin and Aspen) and a handful of other companies that make glass panel replacements (Avidyne being one, King for a short period of time at the end of the last decade being another with the KFD 840).  Around 2010, there were a lot of companies trying to get into the glass panel retrofit game, but many of the products didn’t gain a whole lot of popularity, leaving Garmin and Aspen at the top of the heap.

What about the touch screen GPS market?  Garmin has this pretty much cornered as well, with Avidyne and King just getting into the game.  The gap between Garmin’s GTN series and Avidyne and King is pretty wide.

The answer is pretty easy when it comes to the GPS (go with Garmin!), but not so easy when it comes to the panel.  The G500 and the Aspen Evolution series are both excellent interfaces with strong reliability, so which one do you go with?  Feature-wise, both have a lot of the same features: traffic, weather, terrain, synthetic vision, to name a few.  The presentation for each feature is a little different between the two interfaces.  It just depends on what you like better.

The nice thing about the Aspen system is you can go glass, but you have options on how much glass you want:  1 screen, 2 screens, or 3 screens?  With the single screen PFD, you have all your instrumentation, traffic, weather, and optional synthetic vision.  You don’t need the synthetic vision for the traffic and weather, as it shows up behind your HSI.  It is an honest to goodness glass panel retrofit.

When you decide to upgrade to 2 screens, this is where Aspen has a leg up.  The second screen is a completely redundant PFD and, if you get the 2 hour emergency backup battery installed, acts as the backup instrumentation to the main PFD.  This means you can take out the old steam gauge standby instruments.  This helps clean the panel up.

I personally don’t see the need for 3 screens, but maybe there is someone out there who needs it.

One selling point that Aspen has over Garmin is the wide variety of autopilots and GPS units that Aspen units are compatible with.  The G500 is only compatible with King autopilots, it’s own GFC 700 autopilot (which would be a retrofit), some Collins autopilots, and the Century 21, 31, 41, and 2000.  This does cover a wide array of autopilots, but it keeps some on the outside.  Aspen, on the other hand, is compatible with most autopilots on the market.

Finally, let’s talk price.  Going with an Aspen EFD 1000 PFD (this is the single screen Aspen) will run you somewhere in the area of $12,000.  The price will vary based on the shop and the airplane.  When you want to add a screen, it’s an additional $6,000.  This is for the base, so if you want to add weather or synthetic vision, it’ll run you a little more.

The Garmin G500 comes in around $20,000, again depending on the shop and the airplane.  The screens are bigger on the G500, which is kind of nice, and you are buying a Garmin product, which has a fabulous track record in the aviation industry.

Decisions, decisions.  There really is no wrong answer here.  Both are excellent products with very good track records.  Both have really nice features and don’t hardly fail.  Really, the choice comes down to what you want.

Bruce’s Custom Covers

ByHank Gibson February 15, 2018February 26, 2018

I have used a few different sun shields in airplanes in my flying career.  I have found one that I really like. Bruce’s Custom Covers knocks it out of the park for usability and ease of storage.

Let’s start off with functionality.  Like other window sun shields, Bruce’s Custom Covers fit very nicely into the airplane glare shield and side windows. Depending on the type of airplane you have, some of the window covers use the suction cups and others don’t.  I recently had 2 customers order from Bruce’s, one that owns a P210 that uses the suction cups for all windows, including the glare shield, and the other owns a Cirrus which doesn’t use the suction cups on anything.

They work great.  They do the job of blocking the sun and keeping the cabin much cooler while the airplane is sitting on the ramp.

The thing I like best about Bruce’s Custom Covers is their storage.  Other sun shields require you to roll them up and lash a tie around them. Bruce’s, on the other hand, come folded very neatly in a black canvas bag.  The folded covers don’t take up nearly as much room as the rolled up covers, plus they are really easy to just fold up and store.

Bruce’s Custom Covers also sells plugs for cowling, pitot tubes, etc., as well as aircraft exterior covers.

Bruce’s Custom Covers gets my recommendation for anyone wanting to get some new sun shields.  For those of you in Texas, you know you need them!

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.
