is activated and all significant weather (i.e.

weather that affects the aircraft flight path) is

visible from 0-320 NM.

Customer Quotes

You should let your sales people go with this. Youre competition has nothing like this. I can navigate

all around the weather at any altitude and I dont have to play with the tilt. Im not going to fly through a

cell and hurt anybody.

MultiScanTM works exactly the way an experienced pilot would operate the radar, except it is all done

automatically MultiScanTM is the biggest leap in radar technology since the introduction of C-Band radar.

A major leap in radar technology occurs about every 15 years. This (MultiScanTM) is the next major

leap and represents the future of radar.

I have been using radar for 30 years and now I can push a button and have it do every thing I can doautomatically.

Essentially you have taken the way an experienced pilot operates an x-band radar and automated the

process.

MultiScan is like having a crew member with years of flight experience in the cockpit whose only job is

to operate the radar.

"Now this is how a radar should work....now I can concentrate on what I'm here for....flying the plane!"

Performance

(and Auto Tilt Comparison)

Collins is pleased to provide this MultiScan performance review and Auto Tilt comparison.

We have made every effort to be as accurate as possible. Please do realize, however, that

we may not have incorporated the latest information on our competitors product. Industry

changes are constantly being made and we are obviously not privy to all the engineering

efforts being conducted by our competition.

Auto Tilt Radar(How It Works)


54/57


MultiScan Global vs Auto Tilt

The 80 NM range scale (and below) uses

a relatively low tilt angle that results in

ground clutter just beyond the 80 NM

range scale.

Auto tilt uses EGPWS inputs to detect terrain

height in five quadrants and then varies the tiltto scan over the top of the highest terrain

45

o

45o30o

30o30o

Tilt 1

Tilt 2 Tilt 3

Tilt 4

Tilt 5

The 160 and 320 NM range scales

use a higher tilt to eliminate groundclutter at the radar horizon.

Note: If one pilot selects the 160 NM or above

range scale and the other selects the 80 NM or

below range scale the radar alternates sweeps

using different tilt angles (see right). Display

updates occur every eight seconds

Use of terrain referenced - automatic tilt angle


55/57


Antenna tilt angle using terrain reference

may reduce ground clutter

but will reduce weather detection at the same time Inconsistent weather detection

if terrain is not of the same height

Basic Issue with Auto Tilt Radar(Optimum Tilt Angle Consistent Scans)

MultiScan first scan

MultiScan second scan

If the tilt is varied during the course of a

radar scan (up to 5 times in the case of

an auto tilt radar) the radar will look up

and down in the line of thunderstorms and

produce inconsistent weather returns on

the display when scanning from quadrant

to quadrant.

MultiScan uses consistent tilt angles from

scan to scan. The individual scans are

stored in dynamic memory, ground clutter

is removed and the optimum weather

picture is presented to the flight crew.

Using terrain referenced antenna tilt

will cause unequal antenna tilt anglesas a function of azimuth
