EMS Technologies Canada Ltd. HSD-440 User Manual

23-15-30

NOTE: When the aircraft is stationary, the field may appear as a series of 

asterisks (*).

2. Reports 5 and 17

Report 5 displays information for channel card 1, and report 17 displays 
information for channel card 2.

These reports are commonly used for testing and troubleshooting the system 
and are only available to Level 2, maintenance access users.

You are prompted to select the channel(s) for which to generate a report as 
shown in Figure 4-15:

1

IRS lat/long as interpreted by the HSD-440 terminal

2

Aircraft pitch angle, where UP is positive

3

Aircraft roll angle, where clockwise is positive

4

Aircraft true heading; where the nose of the aircraft is pointing, based on 
yaw offset

5

Aircraft true track; direction the aircraft is flying—not necessarily the 
direction it is pointing (see note below)

6

Aircraft velocity

7

Time based on the system real time clock

8

Doppler frequency offset; increases with velocity (see note below)

9

Antenna azimuth pointing to the satellite, with respect to the nose of the 
aircraft

10

Antenna elevation angle to the satellite, with respect to the horizontal 
position of the aircraft

11

OR to which the system is logged on

12

Reported antenna gain for the selected antenna: Starboard (sbd) or port 
(p/t)

13

Indicates the channel card for which results 14 to 17 relate

14

RF input Carrier-to-Noise (C/No) level; typically 50.0 to 55.0

15

RF input signal level; not to exceed 0 when in-call

16

HSD-440 terminal channel card temperature

17

System call status indicates it is logged on or off for channel 3

18

Satellite beam on which the card is registered
