In the event of a total loss of MGB oil the EC225 is equipped with an emergency glycol spraying system providing up to 30 min run dry capability.

Engine air pressurises a glycol container and delivers atomised glycol directly onto the gears to provide cooling and lubrication.

Annual line checks (confirming proper application of Standard Operating Procedures and techniques on revenue flight)

Periodic training (varying up to 3 years):

TECHNOLOGY – ACAS / TCAS

ACAS/TCAS uses aircraft transponders to track nearby aircraft

This system is mandated on fixed wing transport aircraft over 5700 kg

When another aircraft approaches the crew is warned

If the other aircraft poses a threat the crew are shown how to avoid the threat on TCAS.

Equipment fits vary between types – development of solutions for other types underway

14

TECHNOLOGY - Glass Cockpit / Autopilot

• EC 225 ‘glass’ cockpit

15

TECHNOLOGY - Glass Cockpit / Autopilot

Older types with analogue cockpits have a large number of dials and displays, all with a different purpose. Harder to maintain

Using CRT or LCD displays information presented in a more integrated manner

Smart displays which change colours can be used to alert pilots when parameters approach or exceed certain limits.

Whilst the use of analogue cockpits on the ‘older’ type of aircraft is perfectly safe and what those crews are trained for, the introduction of ‘new technology’ reduces overall cockpit workload.

16

TECHNOLOGY – Helideck Lighting

Helideck lighting has been improved by changing it from the old yellow sodium lights to green deck lighting. This makes the deck more discernable to the crew.

Further developments are in hand, such as electro-luminescent panels to enhance the deck markings at night.

Below is a photograph of a trial installation in Morecambe Bay

17

TECHNOLOGY – TAWS / EGPWS

Offshore helicopters are equipped with the Automatic Voice Alerting Device (AVAD) which gives a voice warning at 100 feet and at a pilot selectable height (check height)

New aircraft haveTerrain Avoidance / Enhanced Ground Proximity Warning Systems. Rather than working on fixed height thresholds (100 ft warning still given) warnings are generated on a combination of height, speed, rate of descent and a terrain database

These thresholds are the subject of a CAA research project which aims to optimise the height/speed/rate of descent combinations for offshore use.

Advanced Avionics to reduce risks

19

TECHNOLOGY - Satellite Tracking

Operators have fitted satellite tracking (SkyConnect, BlueSky, etc)

Aim will be to provide a flight following service as a further enhancement to standard ATC services where appropriate

Voice and text messages can also be passed, which will allow weather updates etc to be passed to the crew no matter where they are

Flight Ops integral to SMS (the execution of our flights and mitigating the risks is core of our Safety Case).

Unusual tasks subject to specific Risk Assessment (e.g. corporate charter, photo tasks).

Company safety database records incidents and also actions and investigations in response.
