To gain a high safety standard
we need to have strategiesbut first of all
we have to accept that risks exist

Risk versus Threat
• The new thinking in ICAO is:
• Threats in flight operations are everywhere
• Threats create risks
• To minimise the risks > know the threats
• ICAO has a new pilot training programm
„TEM = Threat and Error Management“

Risks are createdby
the environment = external threats and
human errors = internal threats

• Human beings make errors
• Errors lead to incidents

Risk assessment?The flight was late and the captain tried to gain some time by high speed taxiing through accelerating the engines initially like for take off.
Design errorIf the throttle system is moved like for take off, the autothrottle system engages and the brakes are automatically disconnected - thus braking is not possible!!
Pilots overconfidence + bad communicationOn the way to the gate, the cockpit voice recorder captures one Pilot saying; “If we go a little faster, then we could get the nose wheel off the ground”.
Pilots complacencyThey were apparently unaware that the autothrottles were set in Take-Off mode, which disconnects the brakes and makes braking impossible.
The „Probable Cause“

As they approached the gate, they found they had no brakes,the result of being in the Takeoff Power mode

Human Error in the Cockpit
• Lack of flying skills
• Lack of communication
• Not adhering to SOP`S
• Overconfidence / complacency
• Bad decision making
