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

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 Bonanza Ownership

    If you walk up to any Beechcraft Bonanza sitting on the ramp at an airport and ask the owner, “How do you like your Bonanza?” be prepared to stand there and listen for 15-20 minutes while he brags about his airplane.

    V35 Bonanza

    The thing about Beechcraft Bonanza owners is that they are almost a part of a cult. They will tell you up and down why the Bonanza is the best airplane out there. They’ll tell you why all the others don’t even come close. They’ll tell you about the payload, the six seats, the variety of configurations you can select from, the ability to land pretty much anywhere. By the time you walk away, you will probably be convinced to buy one yourself.

    Bonanza’s are great airplanes. For those of you new to the single engine piston market, a good comparison for a Beechcraft Bonanza would be a Suburban. Not the flashiest ride out there, but extremely capable, comfortable, and family conscious. If you’re hauling a load, you’ll take a Bonanza over a Cirrus or Mooney any day. Have six people? No problem!

    One of the best things about a Beechcraft Bonanza is the variety of designs. Four seats, six seats, long range tanks, tip tanks, turbo charged, normally aspirated, steam gauge, G1000, Aspen or G500 retrofitted, dual yoke, single yoke, leather, cloth, and a variety of different colors out there on the market make finding a Bonanza that fits your need pretty easy.

    When it comes to picking out an airplane, the first question is always the mission. If you’re thinking about a Beechcraft Bonanza, you’ve already determined you need something with a good useful load. Do you need four seats or six? Depends on how often you’ll be carrying someone or how new of an airplane you want. Older Bonanzas have four seats, but a lot have had significant updating. Newer A36 and B36 Bonanzas have six seats, but are going to cost you more.

    Do you need a turbo charged Bonanza? If you’re in a high elevation area or expect to visit the mountains a lot, then absolutely. If you want a better cruise speed and don’t mind a little less useful load, then go for it. If you’re more concerned about being able to load it up and you aren’t going to cross the Rockies often, then normally aspirated is what you want. You’re probably looking at about 160-170 KTAS with the normally aspirated whereas you get between 180-190 KTAS at altitude with the turbo.

    Do you need tip tanks? Tip tanks have two advantages. One is the most obvious: you get to carry more fuel, therefore you get to go farther without having to stop (or when you stop for the bathroom, you don’t have to fill up with gas). The other advantage is you get a bump up in useful load. I talked to a Beechcraft Bonanza owner a few weeks ago who had tip tanks on his. He told me max gross on his Bonanza was 3,800 pounds and was eligible for an upgrade of up to 4,000 pounds and all it took was paper work for the STC. That’s quite a bit of load!

    G36 Bonanza

    Are Bonanzas hard to fly? When moving up from a typical 172 or Cherokee that most people learn to fly in, it does take some adjustment. But, with good Bonanza training from a qualified Bonanza training instructor, then the transition is no problem. There are tons of resources out there to aid all future and present Bonanza owners in their foray into the Bonanza nation. With the American Bonanza Society and Bonanza Pilot Training, there is no lack of training, thoughts and opinions.

    In need of an airplane that can pretty much do whatever you need? Then a Bonanza may be right for you.

     

  • Wind the Clock

    There is truth in the old adage that 99% of flying is routine while the remaining 1% holds the potential for events that cause those who fly to hold themselves above mere ground-bound mortals. My 37 years of military flying might have distorted that ratio a fair bit given the complexity of high-energy fighter aircraft and the uncertainties of combat, but rest assured we all earn our right to be proud of our wings every time we fly.

    The requirement that a single-seat fighter pilot be able to handle rapidly evolving emergency situations and complex systems diagnosis sets a high bar for any who join that group. However, the lessons we learned and techniques we developed for making fighter aviation significantly safer than in yesteryear have direct applicability to general aviation.

    Prioritization and compartmentalization are two important skills that every pilot should have. These skills amount to the ability to look at a complex problem, quickly determine the most critical elements, and mentally set aside those things that can wait so as to deal with highest priorities first. While this does not sound like rocket science, the art is in the doing!

    The technique for dealing with the immediate onslaught of information, such as when that caution tone or caution light presents and different gauges or displays go haywire, provided the title for this piece.

    All flight training will, at some point, involve what is called situational emergency procedures training, know to military aviators as SEPT. We do this type of training in a simulated cockpit that has all the dials and switches for our particular aircraft. None of the switches and dials do anything, some are just decals on a wooden dashboard, but the presentation allows the SEPT victim to reach for the appropriate switch or lever, while telling the instructor what and why they are doing so.

    One of the most common mistakes new trainees make is that of trying to act too fast, before they have fully and correctly analyzed the situation at hand. Herein lies the titled technique. After blurting out a quick and incorrect answer, the instructor would admonish with: “rather than try to react instantly, maintain aircraft control, analyze the situation, then take appropriate action. The best thing you can do is to reach up and wind the clock. This will give your nervous energy some place to channel itself, while your brain takes in the full situation.”

    Waltham clock

    Winding the clock might seem like an archaic notion, but, amazingly enough, even our most modern aircraft have the same clock we flew with as far back as the 1960s. The Waltham A-13A aircraft clock and timer is a wind-up device that only uses power to light up at night. Unless your emergency involved some type of catastrophic impact to the instrument panel, you could count on at least your clock to be functioning normally. Thus, reaching out and winding it was unlikely to cause any worsening of your evolving emergency and would distract your brain from the need to take some poorly-thought-out action, too quickly.

    Now, in most aircraft there are a few emergencies that will require immediate, reactive actions. In fighters, we call these Boldface Emergencies. For each type of fighter, we memorize, to the letter, the few key actions that have to be instinctive, to prevent disaster. For all other emergencies, there is time to reach out and wind the clock while assessing all instruments and lights to fully understand your situation.

    For your aircraft, know those Boldface or Critical Action Procedures, but for all other emergencies, take the time to maintain aircraft control, “wind the clock” while you analyze the situation, then take appropriate action.

  • A Complex Clearance?

    I was flying in the Rio Grande Valley in south Texas a few weeks ago and heard an IFR clearance given to a King Air that pricked my ears up.  It was a clearance from CRP to LRD, but the routing was one you don’t hear too often anymore.  Because of active military airspace, the routing was via a radial and DME off the CRP VOR (so a point defined by the radial and DME) to another radial and DME point off the LRD VOR.

    It took me a second to think about how to do this the easiest (without setting up the VOR and watching the DME).  After a moment’s thought, it’s actually a snap with the G1000.  You create 2 user waypoints, one for each Radial/DME spot, then put those 2 user waypoints in your Flight Plan.

    Here’s how.

    Step 1

    Using the big knob, go to the Waypoint chapter.  Once there, scroll down to the User Waypoint page using the small knob.

    Step 2

    Press the New soft key.  If you want to name the waypoint something specific, you can do that at the top of the page.  If not, it will default to something like VOR 1 or VOR 2.

    Step 3

    Under Waypoint Type, use the small knob to select RAD/DIS (stands for Radial/Distance).

    Step 4

    Under Reference Waypoints, again using the small knob (or your keypad), type or dial in the VOR identifier, the radial from that VOR, and the DME distance.  Press enter and you are done.

    Once you have both User Waypoints created, then just put them in your flight plan (if you forget what you named them, you can just go back to the User Waypoint page), and off you go.

  • Cirrus Embark

    Free training?

    Yes, you heard correctly.  Last fall, Cirrus released a program called Cirrus Embark.  The Cirrus Embark program offers 3 Free Days of Training to new purchasers of used Cirrus aircraft.  The 3 Days is equivalent to the Cirrus VFR Transition Training Course.

    Previously, Cirrus offered free factory training to anyone who purchased a new Cirrus from the Cirrus factory. Now, anyone buying a used Cirrus gets the same offer through Cirrus Embark at their home airport with a local CSIP training provider.

    IFR pilot?  No problem.  The Cirrus IFR Advanced Transition Training Course is 5 days in length, but the Cirrus Embark program covers the first 3, reducing the out of pocket pay to only 2 days.

    Want more information?  Check out the Cirrus Embark website.

  • MMOPA Operating Practices for the Piper PA46

    I have the privilege of serving on the Malibu & M-Class Owners and Pilot’s Association Safety Committee.  Along with 6 other Piper PA46 instructors, we were tasked with two things last year leading up to the MMOPA Convention in Colorado Springs last October.  The first was to develop a Master Aviator Program (more on that in a later article).  The second was to develop Operating Practices for the Piper PA46 fleet that we as instructors could all get on board with to teach the same thing, allowing everyone in the fleet to fly approaches and patterns the same way.

    When I started instructing in the piston Piper PA46 line (the Malibu, Mirage, and Matrix), I was surprised to find that there were no recommendations anywhere that I could find for approach and pattern power settings and airspeeds.  This led to some experimentation on my part trying to find out what works well for the airplane.  I had originally been given good training in a Malibu, but hadn’t flown one for several years, so my numbers were a bit rusty.

    I have been in the Cirrus world for a very long time.  One thing I greatly appreciated from an instructing point of view about Cirrus was the abundance of guidance the factory gives instructors and pilots on how the airplane is supposed to be flown.  All CSIPs and all Cirrus pilots should (theoretically) be teaching and flying the exact same way.

    I was quite surprised that Piper didn’t put out similar information.  I wasn’t as familiar with MMOPA at the time, but was surprised they didn’t have any information either.

    I apparently wasn’t the only one with a desire to have a little bit more standardization.

    So, without further ado, here are the MMOPA Operating Practices that the Safety Committee put together.  If you are a new Piper PA46 pilot, these numbers are what you will expect to use when you do your Initial training.  If you are a seasoned Piper PA46 pilot, you probably fly these numbers, or pretty close to them already.

    These are tried and true power settings and speeds for the approach phase and landing phase.  They work. That was the goal of the Safety Committee:  put down in writing something repeatable to enhance safety.  I believe we have accomplished that.

  • Scud Running

    I was speaking with a pilot a few months back who was not instrument rated.  He was telling me of his flying experience while continually speaking fondly of scud running.  He told me several stories, most of the time with a smile on his face, about scud running to his destination while staying clear of clouds.  While he was talking, my mind was cycling through the numerous accident reports I’ve seen where a scud running VFR pilot has crashed into terrain or an obstacle.  Needless to say, scud running is not a very good idea.

    This pilot’s stories got me to thinking, how common is the practice of scud running amongst VFR only pilots?  As an instructor, I always teach my private students about personal minimums and making that no-go decision when clouds are below those personal minimums.  The act of scud running falls under several of those dangerous pilot mindsets, get-there-itis, invincibility, and macho-ism, to name a few.

    To bring everyone on the same page, let’s define scud running.  Wikipedia has a very good definition:

    Scud running is a practice in which pilots lower their altitude to avoid clouds or instrument meteorological conditions (IMC). The goal of scud running is to stay clear of weather to continue flying with visual, rather than instrument, references. This practice is widely accepted to be dangerous, and has led to death in many cases from pilots flying into radio towers and high tension wires; however, even instrument-rated pilots sometimes elect to take the risk to avoid icing or embedded thunderstorms in cloud, or in situations where the minimum instrument altitudes are too high for their aircraft.

    To put some numbers with that definition, a scud running VFR pilot would takeoff with a 1200-1500 foot ceiling and stay 700-1000 feet above the ground, right in the area where towers, hills, and rapidly rising terrain reside.

    Scud Running

    How do we change this mindset?  Well, if someone has been scud running for years without incident, the practice becomes normal, like the pilot I mentioned above.  The mindset of invincibility sets in and the practice continues.  This particular pilot can also lead other pilots to adopt the same practice, encouraging them that nothing will happen to them, since we all know that our pilot peers know better than our flight instructors (insert heavy sarcasm here).

    In order to change this mindset, instructors need to emphasize personal minimums from day one.  This includes ceilings, visibility, and winds.  For a seasoned pilot, a review of accident statistics might help the process.

    Scud running is not a safe practice.  If you’re a scud runner, you need to rethink your attitude.  Is getting there really worth it?

    Still not convinced?  Read this pilot’s experience from AOPA.
