Looking for some good $100 Hamburger options in the state of Texas? Here are some other good fly-in eateries around Texas. These are ranked in no particular order because they are all just really good! Most of these are located on the airport property, but a few are in town and worth the drive!
In my book, these are the other great places to stop on a flight in Texas. Always make sure to come hungry! I probably missed a few along the way, so please feel free to add others to the list!
Note: Some of the above restaurants are either closed for COVID, or are only doing takeout. Make sure you call before hand. Google doesn’t always have updated information.
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.
Hank Gibson from Texas Top Aviation will be presenting a seminar on flying Garmin instrument approaches with the different Garmin GPS units. Whether you have a Garmin 530/430 unit, a Garmin GTN 750/650 unit, or a Garmin G1000, all will be discussed. You’ll walk away with some tips and tricks, plus a better understanding of your Garmin unit.
WINGs credit will be given for attending. The seminar is hosted by Redbird Skyport at the San Marcos Airport (KHYI) in Redbird’s large conference room. The seminar will begin at 10am on Saturday, June 30th, 2018.
It’s always quicker to fly than drive and Redbird has plenty of ramp space to accommodate seminar attendees.
Registration is required. Please visit the registration page on FAASafety.gov. Space is limited to 20 individuals, so please make sure you register if you want to attend.
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:
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.
Note: For this article I am comparing a 2008 Cirrus SR20 G3 and a 2008 Diamond DA40 XLS.
Aircraft shopping can be a tedious process. First, a buyer needs to know what the mission is. How far will flights typically be, how many people will be on board, and how fast does the airplane need to be. Then, the buyer has to figure out what the budget is. Finally, a prospective owner needs to figure out how much airplane he or she can handle.
Two very good airplanes for newer pilots transitioning from a flight school 172 who need a faster airplane to build experience in, but also want to experience a glass panel, are the Cirrus SR20 G3 and the Diamond DA40 XLS.
The 2008 Cirrus SR20 G3 is a good airplane. The G3 is equipped with the 6 cylinder, Continental IO-360-ES, 200 HP engine. Performance-wise, an owner can expect 135-140 knots true at 9 GPH (Lean of Peak) or 145-150 knots true at 11.5-12 GPH (Rich of Peak). The 3 blade propeller equipped models have better takeoff and climb performance than the 2 blade propeller equipped planes, especially in high density altitude conditions.
The airplane is equipped with the Avidyne Entegra EX 5000 glass panel system. Most models out there will have Avidyne’s CMAX (Chart View) and all will have the Avidyne EMAX (Engine Monitoring). All came from the factory with the STEC 55x autopilot (though a handful will have the STEC 55 SR, which doesn’t have glideslope functionality). They also came from the factory with dual Garmin 430s. Most units have been upgraded to WAAS.
Some owners have upgraded the autopilot to the Avidyne DFC 90, which is a nice upgrade. The STEC 55x is a rate based autopilot which takes it’s commands from a hidden turn coordinator that is behind the instrument panel in front of the co-pilot’s seat. The STEC has some crosswind limitations on approaches where the pilot can actually fly better than the autopilot.
The DFC 90, however, is an attitude based autopilot that takes it’s commands from the attitude indicator on the Primary Flight Display (PFD). It also adds a Straight and Level button as well as an Indicated Airspeed hold button, adding safety and functionality. It does much better in crosswinds on an instrument approach then the STEC.
A select few SR20s have been upgraded to a single (or dual) Garmin GTN 650 touch screen GPS unit. The GTN 650 is a very nice upgrade. The Garmin 430 is a great unit, but the learning curve with the GTN 650 is much less. The touch screen setup makes a little more sense to the new user.
Values on the 2008 SR20 G3 with 1,000 hours or less run somewhere between $220,000-$260,000, depending on total time and equipment.
A handful of 2007 XLS DA40s were made, but not many. Most XLS models you will see are 2008 and later. These are equipped with the Lycoming IO-360, 4 cylinder, 180 HP engine with the Powerflow Exhaust STC. Due to the Powerflow Exhaust, the performance is equal to the SR20. At 6,000-8,000 feet, you will routinely see 140 knots true at 10-10.5 GPH. Higher altitudes will give slightly better performance and lower fuel burn. Like the SR20, the Diamond DA40 XLS comes with either a 2 blade or 3 blade prop. Go with the 3 blade as the takeoff and climb performance is much better.
Where the DA40 XLS has a leg up on the 2008 SR20 G3 Avidyne is in the avionics. Diamond got on the Garmin G1000 train a little sooner than Cirrus did and the XLS is equipped with the G1000 and GFC 700 autopilot. The Garmin GFC 700 autopilot is the best GA autopilot I have flown with. It is an amazing piece of equipment.
Most, if not all, DA40 XLS models will have both WAAS and Synthetic Vision. Cirrus didn’t get Synthetic Vision till they put the Cirrus Perspective by Garmin in their aircraft in the middle of 2008.
The DA40 has great visibility due to the massive amount of glass surrounding the pilot. The big glider wings give it excellent pop off the runway, but quite a different climb pitch attitude than most other piston single engine airplanes. The airplane does like to float on landing if the pilot doesn’t get the speed right.
Values on the 2008 Diamond DA40 XLS equipped with the Garmin G1000 are around the low-mid $200,000 range.
Performance wise, the airplanes are about equal. Rich of peak, the Cirrus out performs the Diamond, but uses more fuel. Both have about 5 hour ranges (though the Cirrus has bigger fuel tanks, 56 gallons usable compared to the Diamond long range tanks of 50 gallons usable). Useful load is slightly better in the Diamond due to the fact that the Lycoming engine has 2 fewer cylinders than the Cirrus. The Cirrus does have a roomier back seat, a larger baggage area, and a side stick instead of a center stick, but the DA40 has a back door. The Cirrus also has the CAPS system, though an owner has to do a $15,000 repack every ten years. Airplane values are about the same.
I give a slight edge to the Diamond, though, and here’s why. For about the same price, a purchaser can get the Garmin G1000 system complete with the GFC 700 autopilot in the DA40 XLS. The Avidyne and STEC system is great, but the Garmin system is definitely above and beyond. To get the Garmin G1000 in an SR20, you’d have to look at the Cirrus Perspective by Garmin, which came out in late 2008, and you’d be paying $300,000 or more for a single engine piston with 200 HP (though you do get Air Conditioning!).
So for my money, I would go for the Diamond DA40 XLS. I believe you get a little bit more bang for your buck and you don’t lose anything with the DA40 XLS. Don’t get me wrong, I love the Cirrus, but comparing the two, I think the Diamond DA40 XLS rates a little higher.
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.
