Synthetic Vision Technology

ByHank Gibson December 5, 2014December 5, 2014

Let’s say you’re flying in the mountains of Colorado on a cloudy day.  There’s a solid layer from the surface all the way up to 14,000 feet.  You’re inbound to Eagle (KEGE) on the RNAV (GPS) D approach.  There are mountains next to you and below you, but you aren’t concerned since you can see them all.  The base of the last reported overcast layer was 3,000 feet, so you know you’ll break out before the MDA and land no problem.

At 11,100 over AWACC, you clearly see the top of the mountain below you.  You are comfortably above it. You already have the runway in sight as well.  You pop out of the clouds on the approach at 9,700 feet, spot the airport and follow the tower’s instructions to circle north of the runway for a left base for runway 7.

How could you see the mountains inside the clouds?  You have Synthetic Vision installed on your glass panel, that’s how.

Synthetic Vision, which has actually been around since the ’70s when NASA and the US Military first developed it, was first FAA certified for the Gulfstream PlaneView flight deck in 2009.  Garmin, Avidyne, and Aspen are the main general aviation manufacturers of synthetic vision these days.  All Garmin PFDs are now equipped with Synthetic Vision while Aspen gives you the option to upgrade to Synthetic Vision when you get one of their PFDs installed.  Avidyne gives you Synthetic Vision in their R9 upgrade for the Cirrus.

What is Synthetic Vision?  Basically, it’s a 3-D picture on the primary flight display showing terrain, obstacles, traffic, and runways.  It greatly enhances situation awareness in areas of terrain or high obstacles during IFR conditions or at night.

The goal behind the development of Synthetic Vision was to decrease the amount of controlled flight into terrain (CFIT) accidents.  A CFIT accident consists of a perfectly airworthy airplane flown by a pilot (or autopilot) unintentionally into terrain. These accidents can happen in low visibility conditions or at night, but the reason is mainly due to the pilot losing track of his position in relation to obstacles or terrain (or water as was the case with JFK Jr.).

With Synthetic Vision, the goal is to enhance pilot knowledge of what is around the airplane at all times. When you’re at altitude, the terrain below you looks flat.  When you start descending down amongst the rocks, the hills or mountains start to rise up on your screen.  For those used to the coloration with the 2-D terrain feature on a GPS unit, it translates very easily to the terrain coloration on a Synthetic Vision equipped PFD. Terrain that is between 100 and 500 feet below the aircraft is shown as yellow, while terrain closer than 100 feet is depicted as red.

One neat feature on Garmin units is the Highway in the Sky.  When a pilot puts a course or a flight plan in the GPS, the PFD displays magenta boxes at the altitude selected displaying the route.  It’s handy when hand flying to just “fly through the boxes.”  They also display descent angles on approaches.

Synthetic Vision is still optional on Garmin and Aspen units, but I highly recommend springing for it.  It will give you a higher level of safety and keep you out of the rocks.

Hurricane Harvey

ByHank Gibson August 29, 2017August 29, 2017

Texas Top Aviation wants to express our heartfelt concerns and prayers for those affected by Hurricane Harvey along the Texas Gulf Coast and in Houston.  We have several customers in Houston and hope and pray that they are all safe.

If you would like to donate to the relief effort, there are several organizations that are accepting support.  A few are below.

A Takeoff Briefing

ByHank Gibson January 22, 2015January 27, 2015

Takeoff briefings are one of those things that most pilots are taught when they first learn how to fly, but once they get into flying themselves around, quickly fall by the wayside.  There is a reason student pilots are instructed to perform a takeoff briefing before departure.  It gets them thinking about what the plan is after they get off the ground and what to do if something goes wrong.

Takeoff briefings are a good habit to get into.  Airline crews do a takeoff briefing before every departure, even though they have performed a takeoff in that particular airplane thousands of times.  It enhances safety and provides repetition, keeping that knowledge at the forefront of the crew’s minds.

In general aviation, a takeoff briefing should cover what the takeoff procedure is, what the abort plan is, and what the plan after takeoff is.

Takeoff Procedure

Most pilots fly the same airplane all the time, so the familiarity with what goes into a takeoff is there.  But, habits should be formed to brief the takeoff procedure as part of the takeoff briefing.  It doesn’t need to be extensive, just covering the basics of how the airplane is getting off the ground.  Something like this:

• Throttle setting (if turbo charged, will full throttle cause an overboost?)
• Rotate speed
• Expected takeoff roll

That’s it.  Nothing fancy for the takeoff procedure.

Abort Plan

What is the plan if something goes wrong?  It doesn’t have to be an engine failure, maybe the engine coughs when full power is added or maybe the engine doesn’t produce peak RPM.  Maybe the takeoff roll is longer than anticipated and something doesn’t seem right.  Maybe on climb out a door pops open.  Maybe the engine fails at 1,000 feet.  It’s good to keep the plan in the foreground for what to do if an abnormal or emergency situation takes place.

• Brief the aborted takeoff procedure
  • Pick an abort point on the runway based on the expected ground roll
  • What is the procedure if the airplane isn’t off the ground by then?
  • What is the procedure if the engine quits on the runway?
• Brief the engine failure procedure at low altitude
  • If the engine fails over the runway, will you try to land on the runway?
  • What altitude would you elect to turn back as opposed to landing straight ahead?
  • If the plane is too low to turn back, would you land straight ahead or aim left or right?
  • What airspeed will you aim to hold if the engine fails?
• In a Cirrus, what is your minimum parachute deployment altitude?

After Takeoff Plan

After the airplane is off the ground, what’s the plan then?  Are you staying in the pattern or departing the area?  Do you need to adjust your power at a certain altitude?  What altitude are you climbing to?  What heading are you going to fly?  Is your flight plan in your GPS?  This is an excellent time to set up altitude and heading bugs if your airplane is so equipped.

Get in the habit of doing a takeoff briefing before you call the tower or announce your departure.  It get’s your mind focused on the task at hand and then what is going to be happening next.
