Dimming Displays, Pulling Circuit Breakers, and Using Cover-Ups May Help Your Students Learn to Fly Using the Standby Instruments … But there’s a Better Way to Teach Them How to Recognize, Interpret, and Respond to G1000 Failures.
Today’s glass cockpits provide General Aviation pilots with an amazing amount of situational awareness and data. The average private pilot flying a G1000-equipped Cessna 172 arguably has more sophisticated technology at his or her fingertips than many airline pilots flying jets. The downside of glass is that it’s easy to become dependent on it. Thus, pilots using glass cockpit technology must be trained to deal with failures of that technology. This is not always an easy task.
Garmin’s Integrated Flight Deck Guide for Designated Pilot Examiners and Certified Flight Instructors explains how examiners and CFIIs can prepare pilots for the instrument rating by simulating realistic G1000 failures in the airplane. Two methods of simulating failures are presented:
- Dimming the displays to simulate the loss of the primary flight instruments on the PFD (due to an AHRS or ADC failure), complete loss of the PFD, or loss of the MFD.
- Pulling circuit breakers to simulate the loss of the primary flight instruments on the PFD (due to an AHRS or ADC failure); loss of attitude and heading (AHRS failure); loss of airspeed, altitude, and vertical speed (ADC failure); loss of PFD.
Neither method is ideal. Dimming the displays doesn’t allow for simulating individual component failures, and pulling circuit breakers has the potential to both weaken the breakers and affect the safe operation of other equipment. Additionally, neither of these methods (or using paper or plastic cover-ups), give you the ability to simulate failures without the student’s knowledge.
The Flight1 Aviation Technologies G100 Failures Plug-in for VISPRO (along with VISPRO and the G1000 Student Simulator).
Spontaneous, Unexpected Failures
The G1000 Failures plug-in for VISPRO lets you covertly trigger realistic G1000 failures for a student flying Microsoft® Flight Simulator X or Lockheed Martin® Prepar3D™ with the Flight1 Tech G1000 Student Simulator software. Unlike in an airplane, the student will never see you reach across the panel to dim the displays, pull circuit breakers, or put cover-ups into place. The result is a far more realistic training scenario.
Virtual Instructor Station Pro (VISPRO) is standalone software that integrates with FSX or Prepar3D. VISPRO lets you control the simulation’s environment, change the weather, reposition the student’s aircraft, and trigger malfunctions ... all in real time as the simulation is running. It gives you professional-quality tools for monitoring, instruction, and analysis.
Using the G1000 Failures plug-in, the following Line Replaceable Units (LRUs) and individual components can be failed:
- GIA 63 Integrated Avionics Unit
- GTX1 and GTX2 Transponders
- GRS 77 AHRS
- GMU 44 Magnetometer
- GDC 74A Air Data Computer
- GFC 700 Automatic Flight Control System
Additional failures include:
- VHF Comm Radio
- VHF Nav Radio
- RAIM Availability
- Vertical Speed
- Engine Indicators
A unique feature of the Flight1 Tech G1000 Failures plug-in for VISPRO is the ability to realistically simulate the automatic switch to Reversionary Mode after a display failure.
In the airplane, you can only simulate Reversionary Mode by manually dimming one display, and manually switching both displays to Reversionary Mode by pressing the red Display Backup button on the audio panel. What the student sees (the primary flight instruments and engine data on both displays) is realistic, but manually setting up Reversionary Mode like this provides a far less realistic training experience than generating a spontaneous display failure from VISPRO.
The G1000 Failures Plug-in allows students to experience what it’s actually like to experience an in-flight display failure. Failures don’t always occur in cruise, when it’s easy to deal with them. With the G1000 Failures Plug-in, you can present students with challenging scenarios that test their ability to deal with failures when they’re least likely to be able to handle them.
To enable students to practice safely flying the simulation without reference to the glass displays at all, standby instruments (Airspeed Indicator, Attitude Indictor, and Altimeter) are provided.
