Chapter 9: Space-based NAVAIDs Flashcards
1
Q
Where can you find satellite status info?
A
DAIP NOTAMs
2
Q
What is RAIM and how many satellites are required?
A
Receiver Autonomous Integrity Monitoring-detects faulty signals and alerts aircrew
5 satellites
3
Q
What is FDE and how many satellites does it require?
A
Fault Detection and Exclusion-allows detection of a potential satellite position error and for the faulty satellite to be excluded so navigation can continue
6 satellites
4
Q
What does a barometric altimeter aiding do for satellite geometry issues?
A
Reduces number of satellites needed by 1 for both RAIM and FDE (more likely to get GPS navigation for worse satellite constellation issues)
5
Q
Where can you find predictive RAIM (P-RAIM) info?
A
sapt.faa.gov or by contacting a Flight Service Station (FSS)
