EC225 Emergency Lubrication System
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.

PILOT TRAINING - Recurrent
 6-monthly proficiency checks (pilot’s licence revalidated annually)
 Annual line checks (confirming proper application of Standard
Operating Procedures and techniques on revenue flight)
 Periodic training (varying up to 3 years):
 Safety and Survival Equipment
 Underwater Escape Training including cabin evacuation
 Fire Training & Smoke
 Crew Resource Management
12
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
13
TECHNOLOGY - Glass Cockpit / Autopilot
• EC 225 ‘glass’ cockpit
14
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.
15
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
16
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.

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

SAFETY MANAGEMENT SYSTEM
 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.
 Mandatory Occurrence Scheme
