Q<\/strong><\/p>\n
In FCOM DSC-34-SURV-20-10 B DESCENT BELOW GLIDE SLOPE (MODE 5), it states:<\/p>\n
If the aircraft descends below the glide slope by more than 1.3 dots during precision approaches, the following alerts are triggered:<\/p><\/blockquote>\n
Does this mean that MODE 5 is only applicable to ILS and GLS (precision approaches) and not to FLS?<\/p>\n
A<\/strong><\/p>\n
We confirm that Mode 5 alerts cover only ILS\/ SLS and GLS<\/mark> approaches.
\nTherefore GPWS MODE 5 warning will not occur in the case of a glide slope deviation during a FLS approach.<\/p>\nThis behaviour is as per design. Here below is a detailed description of the GPWS Mode 5 alerting logic:
\nThe Mode 5 provides alert when the aircraft flight path descends below the glideslope beam on front-course ILS (or GLS or SLS) approaches.
\nThis mode is active during approach, if valid Radio Altitude is less than 1000 feet AGL and the landing gear is down.<\/p>\nThe Mode 5 uses xLS data which can be ILS or GLS or SLS which depends on mode of MMR. ILS, GLS and SLS are precision approaches.<\/p>\n
The Mode 5 is inhibited<\/mark> when valid MMR Mode data is received, and this data indicates that FLS or mix-FLS mode is selected<\/mark> (FLS is non precision approach).<\/p>\n","protected":false},"excerpt":{"rendered":"
