PDA is suppressed during normal VFR operations in the airport
area and will only generate alerts in the following range and
altitude categories:
Range from nearest
runway or ARP AGL Altitude Range in Which a
PDA Caution Alert is Generated
2 – 5 NM 200’ to 400’
5 – 10 NM 400’ to 500’
10 – 15 NM 500’ – 750’
If a PDA alert has been triggered, a CAS message and aural alert
“Too Low Terrain” will be issued and repeat every 6 seconds until
it is acknowledged or the condition is no longer true. For the
condition to no longer be true, the aircraft must clear the alerting
altitude by 100’. So, for example, if the aircraft is 10 NM away
from the airport and descended to 500’ AGL, a climb to 600’ AGL
must be completed to clear the condition.
