05 Area Navigation System Flashcards
ATTP RADIO
Which one of the following lists information given by a basic VOR/DME-based Area Navigation System when tracking inbound to a phantom waypoint?
Crosstrack distance; Distance to Go
………………………………
The basic RNAV will indicate cross track distance from the selected course inbound to or outbound from the phantom waypoint. The distance shown will always be the direct distance to the phantom waypoint.
In the Flight Management Computer (FMC) of the Flight Management System (FMS) data relating to aircraft fuel flow parameters is stored in the:
performance database.
……………………………………
Data relating to aircraft fuel flow parameters is stored in the performance database.
In the Flight Management Computer (FMC) of the Flight Management System (FMS), data relating to aircraft flight envelope computations is stored in the:
performance database
A pilot is flying between two waypoints defined by suitably located VOR/DMEs. Equipped with a simple 2D RNAV system, this pilot:
reads cross track error and the distance to go on CDI or HSI.
At reference. What is the manually selected heading?
260°(M)
What drift is being experienced?
8° Left
Which of the figures depicts an Electronic Flight Instrument System (EFIS) display in FULL VOR/ILS mode with an VOR frequency selected?
Figure 1
Whilst preparing for a descent ATC ask you to arrive at a specific point and at a specific time. What RNAV capability do you need to comply with such an instruction?
4D RNAV.
An aircraft equipped to operate to RNP 1 and better, should be able to:
compute and estimate its position error.
Which of the figures depicts an Electronic Flight Instrument System (EFIS) display in Expanded (EXP) VOR/ILS mode with an ILS frequency selected?
Figure 5
A 2-dimensional RNAV system has a capability in the:
horizontal plane.
In the Flight Management Computer (FMC) of the Flight Management System (FMS), data relating to STARs and SIDs is stored in the:
navigation database
The Flight Management System (FMS) is organised in such a way that:
the navigation database is read only to the pilot.
Which one of the following inputs to an Area Navigation System (R-NAV) comes from an external, not on-board, system?
VOR/DME radial/distance
Basic RNAV requires a track-keeping accuracy of:
+/- 5NM or better for 95% of the flight time
Using the attached image:
An aircraft is tracking the 255° radial inbound to VOR X. With 15° Port Drift, which of the following indications will be correct when crossing the 121° radial from VOR Y?
(d)
Which of the following are output data from 4D-RNAV systems?
- Flight level and altitude.
- Radials from VOR/DME stations.
- GS and TAS.
- True wind and track errors.
3 & 4.
From which of the following combination of navigational sources provide enough information to the RNAV equipment to calculate the wind vector:
IRS and air data computer.
Under which of the following circumstances does a VOR/DME Area Navigation system switch to Dead Reckoning mode?
The system is receiving information from only one VOR
Which of the figures depicts an Electronic Flight Instrument System (EFIS) display in Expanded (EXP) VOR/ILS mode with a VOR frequency selected?
Figure 4
The navigational database of a Flight Management System (FMS):
contains additional space so that crew members can add their own waypoints.
Which of the following are input data from 4D-RNAV systems?
- DME distances from DME stations.
- Wind vectors.
- Radials from VOR stations.
- TAS and fuel flow.
1 & 3.
One of the benefits of RNAV is:
RNAV allows aircraft to take a more direct flight path without requiring to fly over ground based facilities.
What is the deviation per dot on the HSI when using an EFIS 2-dot RNAV system in the EN ROUTE (ENR) mode?
2 NM
