TIPS AND TECHNIQUES

Maximize Your Map Configurations

Because you can individually configure each IFD

Map overlay, a common technique is to set up one

IFD map overlay to display Datalink weather and the

other to display sensor (e.g. Lightning) weather.

Similarly, you can display METAR flags on one IFD

and winds aloft on the 2

IFD. Likewise, you can

display FLTA and TA on one IFD and turn them off

on the other IFD.

Avidyne would love to hear from you about your dual IFD

techniques at www.avidynelive.com; post them in the

IFD540/440 Touch Screen GPS/NAV/COM section.

WAAS VS NON-WAAS OPERATIONS

The IFD supports both WAAS and non-WAAS operations. In

each case, the IFD is still considered a “/G” system for flight plan

filing purposes.

When configured to be connected to an approved WAAS antenna

at installation, the IFD serves as a fully-certified WAAS GPS

navigator. Published WAAS procedures will be available and

presented in the various drop-down list choices in the FMS and

WAAS glideslopes will be displayed, when appropriate.

When configured to be connected to a non-WAAS antenna or a

non-approved WAAS antenna at installation, the IFD will not

provide any WAAS functionality. For example, WAAS

approaches such as LPVs will not be presented as an available

choice within the FMS.

For dual IFD installations in which one IFD is WAAS capable and

the other IFD is non-WAAS capable (a perfectly acceptable

combination under the STC), there are some limitations on the

nature of data sharing between the IFDs. In this case, FMS-

related data is not shared between the IFDs (e.g. flight plans,

stored routes and user waypoints).
