Results

Q1. Which component of the B737-400 Electronic Flight Instrument System generates the visual displays on the EADI and EHSI?

Flight Control Computer

Symbol Generator

Navigation database

Flight Management Computer

Symbol Generator

Q2. How does the Electronic Flight Instrument System display of a B737-400 respond to the failure of a VHF navigation (VOR) receiver?

It removes the associated magenta deviation bar and/or pointer from the display

The pointer rotates around the display and a VOR 1 or 2 failure warning bar appears

The pointer flashes and a VOR 1 or 2 failure warning bar appears

The deviation bar and/or pointer change colour to red and flash intermittently

It removes the associated magenta deviation bar and/or pointer from the display

VOR/VOR

DME/DME

Q7. What is the deviation per dot on the HSI when using a 2-dot basic RNAV system in the en-route mode?

1 NM

5 NM

2 NM

10 NM

5 NM

Q8. Which of the following lists information required to input a waypoint or ‘Phantom Station’ into a basic VOR/DME-based Area Navigation System?

Magnetic track and distance from the aircraft to the waypoint or 'Phantom Station'

Magnetic track and distance to a VOR/DME from the waypoint or 'Phantom Station'

Radial and distance from a VOR/DME to the waypoint or 'Phantom Station'

Radials from a minimum of two VORs to the waypoint or 'Phantom Station'

Radial and distance from a VOR/DME to the waypoint or ‘Phantom Station’

Q9. In it’s simplest form, RNAV may consist of

A VOR/DME receiver with an associated navigation computer

At least 3 DME sets and an associated navigation computer

ADF and VOR receivers with an associated navigation computer

At least one VOR and 2 DME sets

A VOR/DME receiver with an associated navigation computer

Q10. In order to enter a waypoint that is designated by a VOR into an RNAV, the VOR:

has to be positively identified by one of the pilots

does not have to be in range when entered but must be when used

does not have to be in range when entered or used

must be in range

does not have to be in range when entered but must be when used

Q11. Which of the following is one of the functions of the Course-Line-Computer in a basic Area Navigation (RNAV) system?

It checks the ground station accuracy using a built-in test programme

It calculates cross track information for NDB approaches

It transfers the information given by a VOR/DME station into tracking and distance indications to any chosen Phantom Station/waypoint

It automatically selects the two strongest transmitters for the Area-Nav-Mode and continues working by memory in case one of the two necessary station goes off the air

It transfers the information given by a VOR/DME station into tracking and distance indications to any chosen Phantom Station/waypoint

Q12. Erratic indications may be experienced when flying towards a basic VOR/DME-based Area Navigation System ‘Phantom Station’:

because, under adverse conditions (relative bearing to the Phantom Station other than 180°/360°) it takes the computer more time to calculate the necessary information

when in the cone of silence overhead the Phantom Station

when operating at low altitudes close to the limit of reception range from the reference station

when the Phantom Station is out of range
