Automatic Minimum Safe Altitude Digital Display

Orientation for the displays in these examples, is the aircraft heading
oriented to true north and ground track is displayed using the
two (2) minute arrow allowing to "See Ahead" during flight.

Flight Profile Displays

Indication on the "MSA" Display.

In the following displays, the aircraft is assumed to be at 7000 MSL.

< On this display the aircraft is on the ground and AMSADD is initialized.

AMSADD is in the "taxi mode". Notice that the MSA for the current position of the aircraft on the ground is displayed for reference, but no alert is given because the aircraft is not airborne and the green "MSA" button (icon) has not been selected yet.

< The green "APP" and the yellow "GOA" Icons are in development and are not used for these displays.
They will be operational in the fall of this year.

Enroute

©	Aircraft at or above the MSA MSA was selected after takeoff. In these examples the aircraft is at or above 6,400 feet. The aircraft heading is straight ahead without any wind drift in this example. The aircraft symbol is oriented in the direction of flight.

©	Aircraft enters an area of lower MSA AMSADD keeps you informed when crossing from one MSA to another.

Aircraft approaches higher MSA

Pilot has a "two minute" warning, based on ground speed and track, before entering higher MSA.

This "two minute" is based on the ground speed of the aircraft.

The higher the ground speed, the longer the arrow.

Either do a course reversal, climb, turn left to the lower MSA or all three options.

Aircraft flies into higher MSA

The pilot has over one minute before the GPWS or other alleged terrain warning systems indicates a warning.

Since the MSA is 2000 feet above the terrain, the eminent danger is less than the other systems allow. In this instance, either do a course reversal, climb, or turn left to the lower MSA, or all of the options.

There are some cases where ATC will descend you below the published MSA for traffic conflicts.

ATC is not required to notify the pilot. While AMSADD will give a "CLIMB" warning, which can be cancelled, the pilot will now have a greater vigilance and awareness of the closer terrain.

Enhanced Approach Mode

This mode will be operational in the fall of this year.

Over one half of all CFIT accidents occur on final approach.
No other terrain warning monitors the approach and landing.

AMSADD is the only terrain awareness system that monitors your altitude and course to the runway threshold every 1/4 mile while in the airport area during a precision or non precision approach.

AMSADD has two approach modes, one for IFR approaches and one for VFR approaches where no published approaches exist.

Orientation for the displays in these examples, is the aircraft heading oriented to true north and ground track is displayed using the two (2) minute arrow allowing to "See Ahead" during flight.
