IFR Checkride Flashcards
Pass Checkride
GPS constellation
31 satellites
Orbiting Earth at 12,000 miles
2 orbits every 24 hours
Transmit signal to GPS receiver
How many satellites does it take for GPS antenna position
A minimum of four satellites
Approved IFR GPS
Panel mounted
Approved insulation by the FAA
Found in the flight manual supplement
Handheld GPS
Aid in situational awareness
Not approved by the FAA for IFR
How can a pilot determine if global position system installed in an aircraft is approved for IFR enroute and IFR approaches
Flight manual supplement
How can handheld GPS systems be used?
To aid in situational awareness
What are the primary benefits of satellite-based area navigation (RNAV)
Provides optimal routing and altitudes
Before using any procedure or waypoint retrieved from an airborne navigation database
The pilot should verify the validity of the database during pre-fight and inflate
One way to verify the currency of your airborne navigation database is to
Check your way points to make sure they seem correct and are in the right order
Are handheld GPS systems authorized for IFR navigation?
No
What does WAAS stand for?
Wide area augmentation system
Higher accuracy and reliability
Augmented by ground stations
Certified under
TSO(TECHNICAL CERTIFIED ORDER) C145 or C146
Considered stand-alone unit
Do not need legacy navigation equipment in your aircraft to receive ground-based nav-aid that would normally be used for navigation.
No VOR, DME, and no ADF.
How does a WAAS system work
GPS satellite send signal to reference station on ground,
that signal is then compared to the actual reference station location,
it is corrected and sent to the master station,
to the uplink station
to the Geo satellite
to the airplanes WAAS receiver
What does LPV stand for
Localizer performance with vertical guidance
Accuracy of RNAV - 1
1 nautical mile accuracy 95% of the time
Accuracy of RNAV - 2
2 nautical miles accuracy 95% of time
Non - WAAS GPS are certified under what TSO
C129 or c196
It’s also considered not a standalone unit
Must have avionics for ground-based navigation facilities, must also be functional.
during IFR enroute and terminal operations using an approved non WAAS GPS system for navigation ground-based navigational facilities.
Must be operational along the entire route
During IFR operation using an approved non WAAS GPS system for navigation
The aircraft must have an approved and operational alternate navigation system appropriate for the route
As part of your GPS PreFlight planning our RAIM prediction should be verified, this means that
RAIM is predicted to be available for your entire route of flight including the GPS approaches at your destination
During IFR enroute operations using an approved TSO - c129 or TSO - c196 GPS system for navigation.
The aircraft must have an approved and operational alternate navigation system appropriate for the route
What is the definition of a technically advanced aircraft
An airplane is having a GPS navigation system with a moving map display and an autopilot
The lighter workloads associate with glass digital flight instrumentation
May lead to complacency by the flight crew
Automation in aircraft has proven
To present new hazards and its limitations
When a pilot believes advanced avionics enable operations closer to personal or environmental limits
Risk is increased
