Here’s Why You Need Insight's TAS 1000 MFDS

The essential component for your GPS system

Today’s modern avionics integrate many functions with your GPS, but standard installations leave many important features untapped. The TAS 1000 Multi-Function Data Source was specifically designed to supply all the information needed to fill in the missing pieces of your GPS or MFD display in real-time.

Stand–alone multi-function instrument

In addition to it’s role as an important partner in your GPS system, the TAS 1000 MFDS is a versatile multi-function instrument. Configured by the pilot to meet exact needs, TAS 1000 is simple and user-friendly.

I just love that Windicator!

Everyone underestimates the importance of having an instantaneous display of wind speed and direction until they see it in action. Once pilots have experienced flying with the WindicatorTM, they won’t fly without it!


Full function fuel computer

The simple dedicated fuel computer is now obsolete. The TAS 1000 MFDS offers extensive fuel management information, and is user configured using a rotary switch for fuel setting. TAS makes it easier and faster to initialize, than other fuel computers.

An altitude alerter

The TAS has the best, built-in Altitude Alerter on the market. Unlike other add-on alerters that depend on the coarse resolution of an altitude encoder, the TAS uses baro-corrected altitude derived directly from static pressure.
Improve safety and precision of your IFR procedures with TAS 1000’s altitude alerter.


The magic baro connection

Modern GPS systems require a baro setting input. The TAS 1000 MFDS can read baro setting from many types of altimeters, incorporate it into its calculations, and transmit to most GPS’s. The pilot just sets the altimeter and everything else is automatically updated.

Gradient may save your life

Among the many features that are unique, the TAS 1000 MFDS displays Gradient. The rate of climb or decent is expressed in feet per nautical mile. Safe IFR arrival and departure procedures depend on minimum gradients for safe obstacle clearance. Most pilots have little practical experience gauging gradient. It changes with airplane configuration, engine performance, altitude, temperature, and wind. Gradient becomes critically important when an engine fails. The TAS allows you to maximize glide gradient in a single. In a twin, on one engine, blue line speed rarely offers best performance. However, the TAS display in feet per nautical mile is a direct measure of climb performance under all conditions. Knowing your gradient performance in an emergency can make a critical difference.

SAT temperature will clarify your icing decisions

When an aircraft is in motion the OAT probe reports a temperature higher than the surrounding air. The faster the indicated airspeed, the greater the error. That is why pilots are taught icing can occur in above freezing temperatures. Of course it can’t. The TAS 1000 MFDS computes Static Air Temperature, that represents the actual temperature of water droplets in the cloud. When you use SAT, your icing decisions will be a lot clearer.

ISA temperature, the key to your performance charts

Does your airplane meet the book? Pilot Operating Handbook tables require temperature expressed as a deviation from a standard that changes with altitude. The TAS computes the required ISA temperature from altitude, airspeed, and outside air temperature. Erroneous temperature data will destroy the accuracy of any performance calculation. The TAS provides the correct value.

End your altitude encoder woes

Inexpensive blind encoders are the most common causes of altitude reporting problems. The TAS 1000 MFDS’s accurate altitude information can be sent to your transponder and GPS. It is aviation’s most precise encoder.

Important backup for your essential IFR instruments

Safe flight in IFR conditions demands precise altitude, air speed and vertical speed information. With near perfect accuracy, the TAS 1000 will serve as a standby altimeter, air speed and IVSI, independently of the primary instruments.

Land off airport with wind information

Helicopter, seaplane, EMS, and bush pilots who land off airport can now have the advantage of real-time, right-now wind information.

Simplify floatplane operations

Floatplanes offer a challenge like no other airplane. Every landing is different. The pilot alone must assess the wind conditions and decide where to land. The Windicator’sTM accurate real- time wind information ensures landing directly into the wind on every approach. Even as the winds change below the tree line or near rugged terrain, the WindicatorTM keeps you informed. For floatplane operations, it’s magic.

Predict wind shear on approach

Wind shear is invisible and takes its victims by surprise. Sudden and significant loss of airspeed can bring even the biggest airplane down. Knowledge of real-time wind information on short final can prevent wind shear accidents. When the winds reported by the tower and the WindicatorTM differ, you know there will be a wind shift during the approach.

Optimize the winds

Work the winds to your best advantage on every flight. You’ll save time and money when you do. Pick the best tail wind or the least head wind and easily decide on best speed or range. The dynamic display of actual fuel efficiency responds immediately to changes in conditions so you can assess the effect of winds even in climb.

Aerial application

Drop your payload with Windicator accuracy.

Jet parameter functions

Jet aircraft flight parameters based on current conditions are immediately available on the TAS display. You need not refer to charts, tables or graphs or calculate anything by hand. Just turn the knob to display V1, Vr, V2, Vref, etc for current conditions. This information is custom tailored for your specific aircraft.

TAS 1000 Multi-Function Data Source is several instruments in one. Prior to Insight’s innovation, several instruments were required to provide the functionality now available in one small box. Fuel totalizers have long been a part of the GA cockpit, but air data has traditionally been available only for heavy aircraft - until the TAS 1000.


Air Data computers evolved in jets as a component of sophisticated autopilots, as a data source for FMS (flight management systems), and inertial navigation systems.
The TAS Multi-Function Data Source can provide the same functionality for at a fraction of the cost.


Those who fly jet aircraft are also served by the Insight TAS 1000, as it is TSO certified to 55,000 ft and
500 kts, and can be purchased with additional high performance options.

Certified Accuracy

While the TAS 1000 meets the stringent requirements of no less that 5 FAA TSO’s, it comes with actual calibration documents to prove it. Don’t be surprised to see accuracy ten times better than the requirements.

TAS 1000 Altitude Alerts

An altitude alerter is designed to warn the pilot of deviations from a target altitude. While useful and convenient in cruise, it is most valuable during instrument approaches. Flying step down altitudes of GPS approaches are easier and safer with an alerter.

Alerters are mandatory in turboprops and jets, but troublesome and rare in piston aircraft. Add-on alerters have been prone to false alarms, require constant baro updating and were frustrating to use. The TAS alerter solves these problems.

Instead of reading encoder altitude, it has it’s own internal source of very accurate baro-corrected altitude derived directly from static pressure, so it performs precisely without false alarms.

TAS 1000 has the magic baro connection that will electronically read the baro setting right from your altimeter. Updating the baro on your primary altimeter updates your TAS altimeter, TAS alerter and GPS baro too. Automatically keeping the baro settings in perfect agreement prevents errors and false alarms. Like all other TAS functions the alerter is pilot configurable. You may tailor the warning band to meet your needs. 

The TAS alerter is an integral function of all TAS systems, requires no extra equipment or installation time, no extra panel space and is included at no extra charge.

Install weight is 1 lb.

Alerter Facts:

1000 Feet Warning

When the aircraft is 1000 feet away from the selected altitude the altitude alert you will hear one beep.

Target Warning

At 100 feet prior to target the TAS 1000 will activate the altitude alert and you will hear two beeps. 

Outside The Altitude Warning Band



Once the airplane is inside the altitude warning band the TAS 1000 will enter the warning mode and remain silent. TAS 1000 will activate the altitude alert output and you will hear three beeps whenever the aircraft altitude goes above or below the altitude warning band. 

New Target Altitude if the pilot selects a different altitude alert value before the aircraft exceeds the altitude warning band, the TAS 1000 will not activate altitude alert output (equivalent with three beeps). Instead TAS will monitor the altitude and activate when the aircraft is 1000 feet away from the new target altitude selected value.

Configuring Altitude Warning Band


The alert warning function menu can be configured from the list of active menus in “Configuration Mode”.


TAS 1000 Optional Encoder Module

Altitude Encoder / Overspeed IndicatorEncoder

Insight’s TAS 1000 is an excellent altimeter with accuracy exceeding certified sensitive altimeters. A match box size module converts the TAS altitude data into encoder format. A unique feature of this module is the single cable connection to the TAS. This small cable conveys power and signal. This simplifies wiring and reduces complexity. Several modules may share this data buss to provide encoder information where needed, without running long multiconductor cables from the nose or tail. 
This can save thousands of dollars in installation costs.


The TAS 1000 is TSO’d as a Mach overspeed and IAS overspeed system, features important in high performance turboprops and jets.

Every expansion module is programmed at Insight with overspeed alerts for your specific aircraft model type.

Encoder Facts:

Insight Instruments expansion module system provides altitude information and overspeed warning information to the pilot. It does so by receiving altitude and overspeed warning information from the TAS 1000 Multi-Function Data Source.

TAS 1000 measures static and pitot pressure, computes altitude and air speed every second, and sends them to the expansion module.

The expansion module acknowledges every successful reception of data, by sending back a special message to the TAS 1000 MFDS.

The expansion module receives the data, checks for transmission errors, converts the altitude to Gray code for use by the transponder or GPS. From the same data, the altitude encoder will determine whether or not it should activate the overspeed warning. 

When the pilot wants to run an overspeed test he has to switch to this menu and push the button. During this test, the pilot should hear the overspeed warning.

TAS 1000 - technology you will use every flight.
