Table 1-6. GIA 63(X) VOR Specifications
At -103.5 dBm (S+N)/N shall not be less than 6 dB
At –103.5 dBm deviation output shall not be less than 60% of standard
deflection (90 mV) when a VOR deviation test signal is applied (10 degrees
course difference)
The VLOC Course Deviation Flag must be flagged:
a) in the absence of an RF signal
b) in the absence of the 9960 Hz modulation
c) in the absence of either one of the two 30 Hz modulations
d) When the level of a standard VOR deviation test signal produces less
than a 50% of standard deflection
From -99 dBm to -13 dBm input of a Standard VOR Audio Test Signal, audio
output levels shall not vary more than 3 dB
Greater than 60 dB
The bearing information as presented to the pilot shall not have an error in
excess of 2.7° as specified by RTCA DO-196 and EuroCAE ED-22B
A minimum 100 mW into a 500 Ω load
Less than 6 dB of variation between 350 and 2500 Hz. In voice mode, an
ident tone of 1020 Hz shall be attenuated at least 20 dB
The distortion in the receiver audio output shall not exceed 10% at all levels
up to 100 mW
6 dB BW is greater than 16.5 kHz
