Q

ABAS uses redundant BLANK measurements to support Fault Detection (FD) or Fault Detection and Exclusion (FDE).

29
Q

In an Aircraft-Based Augmentation System (ABAS), the method of integrity monitoring that only uses information from the GNSS is called..

30
Q

Maximum coverage of a Ground-Based Augmentation System (GBAS) station is…

31
Q

In the Global Navigation Satellite System (GNSS), what is the User Equivalent Range Error (UERE)? It is a computed value for:

A

Residual errors

32
Q

An aircraft flying out of sight of land, using GNSS and ABAS (without SBAS), briefly loses power to the IRS. The navigation information of the IRS is lost due to the temporary power loss. What effect could this failure have on how GNSS is used during the flight?

A

ABAS to RAIM

33
Q

User Equivalent Range Error (UERE) or User Range Accuracy (URA) is a signal-in-space error consisting of several individual errors. The most significant of these errors is:

A

Ionospheric propagation delay

34
Q

Ground Based Augmentation System (GBAS) provides data which defines the Final Approach Segment (FAS). The data is transmitted on…

35
Q

Receiver Autonomous Integrity Monitoring (RAIM) is a method used to ensure the integrity of navigational data. With GNSS, this is achieved by checking the BLANK of the range measurements from a group of at least BLANK satellites.

A

Consistency - 5 satellites

36
Q

Using SBAS, up to BLANK geostationary satellites are used to improve accuracy to within 1 m to 2 m horizontally and to advise of any GNSS malfunction.

37
Q

A flight is planned to Longyear Airport in Svalbard (lat. 78°15’N), Due to the high latitude the aircraft GPS will NOT be able to achieve RAIM during the arrival phase of flight, as not enough satellites will be in view. If the aircraft is suitably equipped, AAIM could be used for integrity monitoring by incorporating what two things?

A

IRS and barometric altimeter

38
Q

A performance-monitoring and alerting function is required for BLANK 1 only.

2) RNAV 5
3) RNAV APCH
4) RNP 1 / RNP 2
5) RNP APCH

40
Q

RNAV 2 can be used when?

A

Continental / arrival / departure

41
Q

How is the vertical information for an LNAV/VNAV approach provided?

A

SBAS or baro-VNAV

42
Q

In Performance Based Navigation (PBN), with respect to navigation error components, the Total System Error (TSE) is a measure of BLANK

A

Navigation accuracy

43
Q

Which term refers to the difference between the aircraft’s estimated position and actual position in the context of PBN?

A

Navigation system error

44
Q

Considering PBN procedures, which of the following RNP/RNAV specifications allows the pilot to manually define waypoints not already in the FMS database?

45
Q

What type of turn is excluded in RNP tracks?

46
Q

The Performance Based Navigation (PBN) concept uses terms to describe the requirements of each navigation specification. Which of the following terms defines the capability of the system to perform its function without unscheduled interruptions during the intended operation?

A

Continuity

47
Q

Some approaches are labelled RNP APCH. These approaches are based on GNSS and can be recognised on the charts by what?

A

LNAV minima published
