Flying Eyes Sunglasses

I am on a mission in flying for my head to be as comfortable as possible.  I’m currently going through the process of experimenting with different ANR headsets to see which ones squeeze my head the least (which I’ll be writing a future article about).  In the meantime, I decided to focus on sunglasses.

I wear glasses (can’t do contacts anymore since they irritate my eyes), so anytime I have a headset on, I have frames running underneath my ear cups.  I had a pair of prescription sunglasses for years that were okay, but still caused soreness above my ears after more than 3 hours of flying.  I routinely fly 4-5 hours a day in training folks, so I had to find a better solution.

I saw an ad in Flying Magazine one month for Flying Eyes sunglasses.  It was a relatively new company with a cool concept.  A pilot started the company with the goal to create as thin a pair of sunglasses frames as possible to increase the comfort and decrease the ANR loss when wearing sunglasses.  What the company came up with is pretty cool.

The ultra-thin frames on the all the different Flying Eyes models are made out of Resilamide.  The material is so strong that the frames can be bent back and forth while not breaking.  The company even brags that the frames are virtually unbreakable.  I had to try these out.

I ordered a pair of the Golden Eagle Sport sunglasses.  The process of getting prescription lenses in them was no big deal and took about a week.  The eyeglasses shop initially thought the shape of the lens could be an issue, but it proved no problem at all.  The lens manufacturer even managed to chip the frames, but Flying Eyes sent a new set of frames for free, even though it was not at all their fault.

In about a month and a half of flying with them, they are very comfortable.  Some squeeze on the side of my head after extended periods of wear underneath a headset, but I’m exploring headset options currently (see above).  Much improved over my last set of sunglasses.

Flying Eyes offers several different frame models, some of which are prescription compatible and some which aren’t.  The Golden Eagle Sport frames run about $180.  Orders can be placed on the Flying Eyes website.

  • Simplified Instrument Approach Briefing

    In instrument flying, I am all about keeping things simple.  There is a ton of detail that an instrument pilot can get bogged down in.  When an instrument pilot gets bogged down, he gets distracted from flying the airplane.  When he gets distracted from flying the airplane, dangerous circumstances can happen.

    I like to keep things simple.  When I first started instructing, I developed a very simple instrument approach briefing that captures everything that is necessary on an approach plate, but prevents getting bogged down in the details.

    I call it the BBC instrument approach briefing.  Here it is:

    Brief

    rnav-32-kssfFirst things first.  The first step of an instrument approach briefing is to brief the approach plate.  There are a bunch of acronyms out there that instructors tell their students to memorize that only cause confusion instead of helping get the plate briefed.  To keep it simple, just work your way across the plate and you’ll get all the information you need.

    Start in the top left hand corner of the plate, with the approach course, then work your way right and down, as follows:

    • Approach Course (or Nav frequency if flying a VOR/ILS/LOC)
    • Runway information
    • Notes (these are good to brief the night before as a lot are irrelevant to GA pilots
    • Missed approach
    • Frequencies
    • Planview and MSA
    • Profile View and Minimums

    Simple enough, right?

    Build

    Now that you know what you are planning on doing, you can now take the second step in the instrument approach briefing and build the approach in your GPS.  You know your approach type, you know your transition, and you know what your minimums are.  Taking all that information, you can now build it in to your system.

    Checklists

    Once everything else is done, don’t forget the checklists.  The descent and before landing checklists still need to be done as part of an approach.  The best time to do these is before joining the approach so that you don’t have to worry about flying the approach and looking at a checklist at the same time.  Even better, memorize the checklist and you don’t have to look at anything!

    Most importantly, you want to be configured properly for the approach by the final approach fix.  Gear, flaps set, power set, so all you have to worry about at that point is following the needles and trusting your instruments.

  • Angle of Attack (AOA)

    You are hand-flying an in-the-weather descent, power back, heading for the FAF. You start a 30 degree banked turn at your lead point to cross the FAF, when your passenger behind you gasps. Looking over your shoulder, you see he has spilled his drink into his lap…too bad for him! However, when you turn your head back to your panel, your inner ear tumbles and you see 45 degrees of bank, 15 degrees nose low, airspeed increasing.

    Congratulations! You have managed to get distracted and sucked into an unusual attitude recovery. By the book, you should roll wings level, pull to the horizon, and adjust power as necessary to keep the airspeed within limits. In this scenario, if you had not experienced vertigo, you might have been able to roll to less than 30 degrees of bank, recover your turn, pull the nose up to less than the original descent attitude, pulled a bit of power to slow back to your desired penetration speed and then resumed your desired ground track. However, this would only be appropriate if you had full situational awareness as to the deviations caused by the look over your shoulder, plus full confidence that the moderate corrective actions would put you back on your desired flight path.

    As a military aviator, I learned unusual attitude recoveries based upon hard maneuvering at extreme pitch and bank angles. In the hard-maneuvering environment, an unusual attitude could be 90 degrees straight up, airspeed decreasing below 120 kts…or 80 degrees nose low, 135 degrees of bank, airspeed increasing through 500 kts… etc. In these cases, understanding angle of attack, or AOA, is critical to maintaining controlled flight and returning to a normal attitude.

    In an extreme nose-high attitude, a military aviator is trained to roll the aircraft to 90 degrees of bank, ease off the back-stick pressure to reduce AOA, add power as required, and allow the nose to slice back towards level, rolling to wings level as the nose approaches the horizon. If nose low, the recovery procedure is to roll rapidly, within asymmetric g limits, until wings level, then to pull at optimum g loading to recover to level flight. For the nose-low recovery, power was normally reduced until airspeed could be assessed and brought under control. However, when doing the nose-low pullout at 7-9 gs, pulling the power for too long would leave you much to slow to resume combat.

    The AOA gauge on a fighter’s glare shield is a primary reference during hard maneuvering and for landing. The AOA for optimum maneuvering is 13 degrees, displayed as the green circle or “green donut” on the gauge. The red chevron on top represents a slow condition of 15 degrees or more and the yellow lower chevron represents 11 degrees or less.

    For normal landing in the F-16C, the pilot slows to 220 kts and configures abeam the touchdown point while mentally computing the final approach airspeed of 136 kts plus 4 additional knots for each 1000 lbs of fuel. When rolling off the perch and flying the final turn, the pilot would usually only glance once at the airspeed once to ensure final turn airspeed of 180 kts while using the AOA sight gauge as the primary indicator of a best performance turn. As long as the AOA was green donut (13 degrees) or less, you would not stall. If on speed and 13 degrees wasn’t going to get you around the turn to line up with the runway, you knew you were going to overshoot. You never wanted to see the red chevron of 15 degrees or more as that meant you were too slow, pulling too hard, and in danger of building an un-recoverable sink rate!

    Few GA aircraft are currently equipped with AOA indicators, though there are several after market devices available for retrofit. However, knowing the impact of AOA and how to manage it is vital to safe aviating, even without an AOA gauge. The bottom line is, as long as you don’t ask the wing to produce more angle of attack than it can handle, you won’t stall.

    Practicing final turn stalls, to know what the wing feels like as you get too slow or pull too much on the controls, increasing AOA past the critical point, will keep you safe when you encounter that unexpected overshooting wind or you find yourself inadvertently on too tight of a downwind leg. Better to overshoot or take it around to try again, than to pull too hard and exceed critical AOA.

  • Flying the RDD LX7

    I get to fly a lot of different airplanes in my chosen career. There aren’t many airplanes that I take off in, then say “Wow,” and have a big smile on my face. The RDD LX7 was definitely one of those.

    I wrote about the RDD LX7 in the past, bragging about everything I read about it. The blogs all advertised 250 KTAS and 17 GPH and FL250, all of which are eye popping numbers.

    Lo and behold, those numbers are true.

    I got to go up to RDD’s Redmond, Oregon facility in April 2021 to get my initial training in the RDD LX7 and I couldn’t wipe the smile off my face. The 3 screen G3X Touch layout is very impressive and not crowded like I thought it would be. Being familiar with the G500TXi, there are some G3X specifics that take a little getting used to, but overall, it’s a good system. The main GPS and number 1 radio is a GTN 750Xi.

    We took off from RDM and proceeded to climb at 140 KIAS, which equated to 2,000 FPM. We only had half tanks (which is still 90 gallons of fuel!), but it climbed with no problem. It’s extremely responsive as I learned while doing the basic flight maneuvers. The stall speed of the airplane (the biggest problem with the Lancair 4P, the airframe that the RDD LX7 is derived from, was the terrible wing design and extremely high stall speed), was in the low 60s or high 50s, with the stall being extremely docile.

    The airplane handled very similarly to a Columbia 400, but seemed even more responsive. The glide ratio isn’t as good as some, but it’s still better than a Cirrus (plus it still has a BRS system to boot).

    The big test was the flight to San Antonio from Redmond to bring the plane home. The new owner and I departed RDM with the tanks full of Avgas (180 gallons), then got up to a cruise altitude of FL210. After setting power and leaning, the numbers came out true to spec: 252 KTAS, 17.5 GPH.

    The greatest part? We stopped in Santa Fe to stretch our legs and we didn’t need fuel. We still had 100 gallons left! That left us plenty to get to San Antonio with 40-50 gallons left over. Another RDD LX7 owner flew his piston direct from Redmond, OR to Jacksonville, FL, non-stop. It was over 9 hours. That’s impressive.

    You can’t beat the purchase price, either. A new Cirrus SR22T runs a little north of $1.2m. A piston engine LX7, that is pressurized, 70 KTAS faster with a much longer range, and still has a BRS, is between $850,000-$900,000. An LX7 starts to make a whole lot of sense when you weigh all that. There is also a PT6 option with several different sizes and horsepowers to choose from, which costs more, but you see 300 KTAS.

  • Coflyt Ownership App

    A new app came out last year that fits a need for many owners. Coflyt, available on the Apple App Store for $14/month for up to two airplanes, helps immensely with staying organized. Those questions of, “When is my oil change due?” or “Has the plane had it’s IFR inspections?” are easily answered by checking the app instead of having to dig through maintenance logs.

    Not only does Coflyt help keep track of maintenance, but it also houses squawk lists that owner’s can send to maintenance shops as well as keeping track of Airworthiness Directives. If the pilot remembers at the end of flights to put the amount in, it even shows how much fuel is remaining in the airplane.

    For flying clubs and partnerships, it provides easy scheduling without having to share calendars. Payments can also be taken and flights tracked. No more paper flight sheets after flights to track down.

    As a pilot, it helps immensely to be organized. For $14 a month ($36/month for partnerships or flying clubs), that’s a small price to pay.

  • Garmin Perspective Missed Approaches

    Are you a Cirrus pilot with a Garmin Perspective?  Still can’t figure out the use of the go around button?  Read on!

    When it comes to flying an instrument approach, we as pilots are assuming we are going to land.  Most of the time, we won’t even take off if the ceilings or visibilities are below the minimums for an approach.  95% of the time, we do land.

    There is the other 5% of the time when something unexpected happens, whether we get a full scale deflection, or we don’t see the runway at the published minimums, and we have to perform a missed approach.

    When instructing, missed approach procedures are actually what I see the most deficiency in when instructing an instrument rated pilot.  It’s not necessarily configuring the airplane for a missed approach procedure, it’s the button pushing involved in setting up the GPS properly.  When a pilot isn’t proficient in the button pushing, that button pushing distracts the pilot from actually flying the airplane, which can lead to a dangerous situation.

    I am going to spend a few articles on flying a missed approach with different GPS and different autopilot configurations.  Today, I will be addressing the Garmin Perspective with a GFC 700 Autopilot, which is what all Cirrus Aircraft after 2009 are equipped with.

    The Garmin Perspective Missed Approach Procedure

    Once the decision to execute a missed approach has been made, here is the step by step procedure:

    • Full Mixture and Full Throttle
    • Simultaneously push the Go Around button on the underside of the throttle.  This does the following:
      • Sets the Garmin Perspective Flight Director to Go Around Mode (7.5 degrees pitch up and wings level)
      • Takes the Garmin Perspective GPS out of Suspend Mode
      • Switches the CDI back to GPS mode if it is in a different mode
      • Garmin Perspective with GFC 700 Autopilot stays on
    • Flaps up
    • Confirm airplane is climbing
    • Set altitude bug for missed approach altitude (assuming it isn’t there already)
    • Set NAV mode and IAS mode on the Garmin Perspective GFC 700 Autopilot

    Garmin perspective

    That’s it.  When Garmin and Cirrus got together to create the Garmin Perspective with the GFC 700 Autopilot, they tried to make as simple but robust system as possible.  Once you have the procedure down for the right buttons to press, then the procedure is relatively straight forward.
