GPS (FW) Flashcards
Who developed the GPS system?
Department of Defense.
The GPS satellite system is designed to ensure at least how many satellites are always visible to a user worldwide?
5
Where can you find information on GPS satellite outages?
All the answers are correct.
RAIM allows the GPS receiver to:
Perform integrity monitoring.
How many satellites are necessary for Fault Detection and Exclusion with baro-aiding?
5
After RAIM has determined a satellite is providing corrupt information, why should the GPS derived altitude NOT be used in lieu of baro-aiding?
GPS vertical errors will make integrity monitoring functions invalid.
How can the pilot receive satellite NOTAMs?
By requesting GPS aeronautical information during a briefing.
What does RNP mean?
Required Navigation Performance.
The 0.3 sensitivity on the GPS is for which mode of flight?
Approach.
How do you know if a GPS is approved for IFR operations?
The correct TSO will be listed in the STC for the device.
Can a pilot use a STAR procedure with the GPS?
Yes, if it is loaded in the database.
What is the purpose of the Terminal Arrival Area (TAA)?
Provide a seamless transition for aircraft equipped with Area Navigation (RNAV) systems.
For a TAA approach, when may a pilot descend inside the TAA sector from their enroute altitude?
Once cleared for the approach.
Using the figure, what altitudes must a pilot maintain within the left or right base area of the TAA?
6,000 ft MSL until within 17 NM of the IAF and then descend to lower charted altitudes.
What types of GPS waypoints appear on an approach chart?
Fly-over and fly-by.
What are the different types of minima that may be provided on a GPS approach chart?
LPV, LP, LNAV/VNAV, LNAV and circling.
When an approach has been loaded into a flight plan, at what distance from the airport reference point will the GPS “ARM”?
30 NM.
When conducting a GPS approach, the CDI sensitivity will:
Scale based upon on where on the approach the aircraft is located.
What is the best way for a pilot to fly the lateral portion of a missed approach procedure?
If it is safe to do so, the pilot should wait to initiate the missed approach at the MAWP.
