Keeping Your Margin

ByPete Greenwald November 23, 2016December 6, 2016

Just south of the equator in the mountains of Papua, Indonesia on the island of New Guinea, pilots spend their days carrying food, building supplies, doctors, pigs, and passengers into some of the most remote and extreme airstrips on the planet. That’s where I fly.

Each morning I load my Cessna Grand Caravan with 2,600 lbs of (insert strange cargo here) and depart my home base of Wamena just after the sun sends its first rays of light across the waking skies above. I spend my day winding through narrow valleys and crossing high altitude mountain passes with building clouds and poor communication, only to land on short, narrow airstrips with steep slopes and little room for error. Most of these one-way in, one-way out runways require me to commit to landing well before touchdown due to terrain that is too close to allow for a safe go-around. Everything better be right when I cross that decision point or I could be in for some excitement.

The need to keep wide margins of safety might seem obvious in environments like mine, but that doesn’t make them any less important where you fly. You may be a new pilot or an old timer, but keeping your margin should always be on the top of your priority list.

Let’s unpack this further. Margin is not just maintaining the regulatory requirements for cloud clearances or minimum altitudes. It’s more than planning for an alternate airport or carrying the required fuel reserve. Margin is breathing room. It is that extra maneuvering room, the Plan C, the well thought out options that provide you multiple “outs” in any given situation. Margin is what gets you home when things take a turn for the worse.

Margin comes in all shapes and sizes. For myself it includes maintaining double my required turn radius in narrow valleys or choosing not to land when my groundspeed is just 1 knot too high at a short and slippery airstrip. For you, it could be determining a ceiling or visibility minimum requirement that is more conservative than the legal ones or setting a wind limitation that you know is reasonable. When it comes down to it, keeping your margin means you don’t push to the ragged edge of your skill or the aircraft’s capability.

Margin can also refer to your mental or emotional capacity. Are you mentally prepared to divert and miss that important event because the weather is getting bad? Are you ready to handle the disappointment of passengers when you arrive over your airstrip and choose not to land due to approaching rain or a factor that is difficult for a non-pilot to understand? Are you willing to cancel a flight on an important client because you are coming down with a cold or didn’t get adequate sleep? As the PIC of your flying machine, you alone are responsible for the safety of the aircraft and the people on board and those are the tough calls that only you can make.

Fatigue, overconfidence, and complacency are the biggest obstacles to keeping your margin. They are all very subtle dangers and you may be experiencing them without even recognizing it. Fatigue can slow down your thought process leaving you behind the plane and backed into a corner before you know it. Overconfidence might cause you to push weather or commit to a course of action that has no favorable alternatives. Complacency will lead you to believe that, because you have 2000 hours in a particular make and model, you don’t need to do a thorough preflight or complete the pre-landing checklist.

Regardless of experience level, operating environment, fancy avionics, and level of proficiency, margin is something that we all need plenty of. So as you go about your upcoming flights, be asking yourself what you can do to build in more margin. It just might be what gets you home.

Matching the Airplane with Your Mission

ByHank Gibson February 5, 2019February 18, 2019

Has it come time to buy your first airplane?  Have the skies been calling your name?  Or are you just tired of standing in the airport security line then getting shoved in a long metal tube with no leg room?  Or, maybe you are a businessman who does business in remote areas that have local airports but are hard to get to commercially.

Wherever your need is, you have decided it’s time to make a purchase.  If you are familiar with aviation, you may have an airplane in mind that you would like to have, but is that the right airplane for your mission?  If you are new to aviation, you may have no idea what airplane to go for.  Here are some helpful hints in narrowing down the different airplane options out there to fit your specific mission.

Flying For Enjoyment, but Not Going Far Fast

If you’re just a weekend flyer who is tired of dealing with flight school rentals, but you don’t need to carry a lot of people or go very far, your options are pretty numerous.  Anything from a Cessna 152 to a Piper Cherokee, maybe a Beech Sundowner, or a Bellanca Viking, or anything in between.  If you are content with taking a weekend hop for a hamburger at 100-110 knots, you have limitless options for airplanes.  Tailwheels (Cubs, Citabrias, Huskies) are excellent birds for you well.

Getting Places Fast With Only You and Maybe One Passenger

Need to go 200-300 miles fast and not worried about weight?  A Cirrus SR22T, a Columbia 400, or Cessna Corvalis might be just what you need.  Cruise speeds on those are all around 180-190 knots at 10,000 feet. All are oxygen equipped if you want more speed higher up, as the service ceilings are 25,000 feet.  Payloads run in the range of 400-500 pounds with full fuel.  All these have air conditioning options, too.

Hauling More Weight, but Still Need the Speed?

A little slower (150-170 knots) but a little bit more payload options are A36 & B36 Bonanzas, Piper Saratogas, Cessna 206s, or Cessna 210s might suit your fancy.  All come in turbo models if you are a high elevation dweller.  The Cessna 206 has been used for many years as cargo and people haulers in remote regions like Alaska, South America, and Africa.  I’ve even seen pictures of snowmobiles being carried in a 206.

Tired of Oxygen Cannulas?

The next step up from a Cirrus, Corvalis, or Saratoga is the Piper Malibu.  A bigger brother to the Saratoga, the different PA-46 models offer one of the best options for a single engine piston out there.  All except the Matrix (PA-46-350T) are pressurized, all the pistons cruise about 200 knots, and all are configured with club seating with plenty of leg room.  Useful loads range around 1200-1400 pounds (they hold 120 gallons of fuel, so payloads range from 480-680 pounds).  The original Malibu (PA-46-310P) only burns 16.5 GPH so that allows partial fuel to be carried to allow more people and bags.  All have 6 seats.

Need to Carry Even More Weight?

It’s time to get into the piston twin market, then.  A Cessna 414, a Cessna 421, a Cessna 340, a Beech Duke or a Beech Baron are all pretty good options here.  The 421 and the 414 have the largest cabins, while the Duke has the highest useful load.  Cruise speeds range from 200-220 knots, but the cabin is roomier and you get a few more pounds useful load than a piston single.  If you do get into a 421, get good training as they are equipped with Continental geared engines, which can be tricky to operate if you don’t know what you are doing.

Need to Carry a Lot of People and Go Fast?

Turboprops are the way to go for you.  King Airs have the most utility while  the Pilatus PC-12 is the cream of the single engine turboprop crop as you can put almost anything you want in it.  If you have 4-5 passengers, stay away from a Piper Meridian as you can’t carry a lot of weight.  Those are better for 2-3 passengers at the most (plus a pilot).  The TBM 900 is pricey, but fast (300-325 knots).  The original TBM 700 can be had for under a million bucks, you get 280 knots, and a very usable useful load.  You still can’t fill all 6 seats with full fuel, but you can do more with it then a Meridian.

Have a Boatload of Money Sitting Around?

A jet might be for you then.  Fuel, insurance, maintenance, and hangar costs are high, but jets will get you places real fast with room for all your friends and family.

Garmin VNV

ByHank Gibson April 19, 2017

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

IFR Garmin VNV Use

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

Cirrus Vision Jet Receives FAA Certification

ByHank Gibson November 8, 2016

The long anticipated certification of the Cirrus Vision Jet finally happened.  On October 30th, the FAA awarded certification to Cirrus’ single engine jet.  Marketed as the world’s first single engine personal jet, the Cirrus Vision Jet will seat five adults, two children, and cruise around 300 knots.

The Williams FJ33-5A Turbo Fan engine is operated by a FADEC, single handle throttle, similar to the throttle in the piston powered Cirrus family.  In fact, the SR series was taken into consideration when designing the Cirrus Vision Jet in order to simplify the upgrade for pilots.  Many of the buttons and knobs are in the same places in the Cirrus Vision Jet.

The Cirrus Vision Jet is equipped with the Cirrus Perspective Touch by Garmin that is very similar to the Cirrus Perspective by Garmin in the piston powered line.  Equipped also with the Flight Into Known Icing system and the Cirrus Airframe Parachute System (CAPS), both of which are standard.

Unlike the piston powered Cirrus lines, the CAPS system on the Cirrus Vision Jet is actually mounted in the nose.  Also, unlike the piston lines, the jet CAPS is integrated with the aircraft avionics to slow the airplane to between 67 and 160 knots when the system is activated.  In the jet, the CAPS system was designed to withstand higher weights, higher speeds and higher altitudes.

Cirrus hopes to start deliveries of the Vision Jet by the end of the year, with many more rolling off the line in 2017.  All Cirrus Vision Jet pilots will need to be type rated in order to fly the aircraft.  Cirrus is doing all the type rating training in house at their new Vision Center in Knoxville, Tennessee.
