Witnesses to the recent Black Cat cruise boat accident after it grounded just outside the Akaroa Heads are urged to submit a statement to TAIC immediately.
E-Protect is a system on locomotives that uses Global Positioning System (GPS) technology to monitor the speed of trains approaching compulsory-stop boards (CSB) and applies a penalty brake if a train does not stop at the CSB location. The system is designed only to enforce a stopping sequence. Once the train has stopped, the E-Protect system becomes inactive, allowing the train to be moved through the PWA. The placement of the compulsory-stop protection boards is a necessary reminder for locomotive engineers to prepare their trains for stopping at designated places to avoid emergency brake applications.
E-ruc system
A management tool that records the times and locations of vehicle events, such as when a vehicle’s ignition is turned on and off, the vehicle enters and/or exits a geo-fenced site, the vehicle turns or the vehicle is stopped, and the vehicle’s speed and global positioning system (GPS) location, at predetermined time intervals. The system determines that the vehicle has stopped when its speed falls to less than four kilometres per hour

Electronic block protection
A protection activated on the signalling system operated by train control when required to ensure that signals and points are not cleared into a protected work area, or to prevent conflicting rail movements.
Electronic blocking
Electronic blocking is a method of protection whereby the train controller uses the train control system to prevent signals held at red (stop) being placed at green or yellow (proceed). Having to stop for red signals prevents rail traffic from entering a section of track that has been blocked.
Electronic navigational chart (ENC)
A digital chart viewable in ECDISs
Electronic Train Protection (ETP)
A train stop protection system designed to reduce the consequences of Signal Passed at Danger occurrences. ETP is an on-board system that is able to read a ‘signal red’ message from an ETCS balise (an electronic beacon or transponder placed between the rails of a railway as part of train control or a protection system). Trackside ETCS was installed throughout the Auckland Metro network as part of the electrification triggered re-signalling.
Elevation
The primary unit of measurement of altitude and elevation or height is the metre. However, the most widely used unit of measurement in aviation is the foot. Metric altitudes and flight levels are used in some countries, such as China and Russia. AIPNZ GEN 2.1 states that the unit for measurement for altitudes, elevations and heights is feet.
Embarkation
Boarding or going on a ship
Emergency door release
A device located on the outside of a train’s passenger car, primarily for the use of emergency services to enable the doors to be operated manually in the event that they cannot be opened by normal means. Also referred to as an emergency egress device.
Emergency Locator Transmitter
An emergency locator transmitter transmits a distress signal to the Cospas-Sarsat search and rescue satellite system.

Designated emergency areas for all crew during emergencies. The master and crew confirm the whereabouts of all personnel and initiate a plan to address the emergency using specialist equipment.
Empennage
The tail assembly, including the vertical fin, horizontal stabiliser and tail rotor.
Empennage assembly
A horizontal and vertical stabiliser that is located near the aft end of the tailcone. It is designed to provide stability during flight.
Enclosed waters
Enclosed waters are inland waters or waters within sheltered waters
End of daylight
Civil Aviation Rules (CARs) 1: Definitions defines night beginning at the end of evening civil twilight, which is calculated from tables in AIPNZ GEN 2.7, s1.4 Daylight tables.
Energy attenuating seats
Energy attenuating seats on Airbus Helicopters rotorcraft are designed to stroke and/or plastically deform upon severe impact, absorbing all or a portion of the energy transmitted to the seat during an impact.
Engine room tank-top
The floor of the engine room, under which various tanks and voids are located.

A system that detects whether a locomotive has failed to stop before reaching a compulsory stop board. If this occurs it automatically activates the emergency brakes on the locomotive, bringing the train to a forced stop, thereby providing an independent backup to the driver

ERM
Engine room resource management
EROAD
A proprietary, GPS-based tracking and monitoring system commonly used to track and monitor land-based vehicles.
Error recognition
There are a number of equipment design principles to protect against human error, one of these being that the response of the system to an operator’s input should be clearly and immediately visible to the operator. In this case, while control inputs are made using the remote-control pack, the pack itself gives no feedback of the system response ie, what movements the locomotive is making as a result of the control inputs.
