TEM Notes Flashcards

1
Q

What is T.E.M

A

TEM is an attempt to develop a mind-set which enhances the identification of threats,
minimizes the opportunities for error, and resolves those errors when they do occur.

Q

What are threats?

A

Threats originate in the environment outside the cockpit or in the cockpit and are not
directly attributable to something the crew did or did not do.

Q

What are errors?

A

Errors originate from pilot actions or inactions that have the potential to adversely affect the
safety of the flight.

Q

What are Undesired Aircraft States?

A

Include such things as inappropriate flap selection on take-off or landing, flight above or below the desired altitude, airspeed too high or too low during climb or descent or unintentional stalls or spins. Note that an undesired aircraft state can result from either a threat such as turbulence or wind shear, or an error such as inappropriate use of controls.

Q

Examples of latent external threats include?

A

Latent external threats are not directly obvious to the pilot but are lurking in the background waiting for a particular set of circumstances. They include such things as a ‘user unfriendly’ work environment such as poor cockpit design or instrument layout, aircraft design characteristics and company policies that do not adequately address proper maintenance issues or pilot fatigue and optical illusions such as sloping runways or ‘black hole’ approaches

Q

What does Internal threats mean?

A

Internal threats are brought to the cockpit in the persons of the pilot and crew. They cannot in themselves be called errors but they increase the likelihood of errors.

Q

What are some Examples of Internal threats?

A
They include such things as:
• Pilot fatigue
• Team familiarity in multi-crew aircraft

Q

What are some examples of environmental threats?

A

They include:
• Weather such as thunderstorms, icing, cross wind/tail wind/downwind wind shear and turbulence
• Airspace communication problems such as may occur in CTA or in a CTAF area
• Ground environments at airports including signage, the presence of birds or obstructions
• Terrain about and below the aircraft
• Operational pressures such as late arrivals or unserviceability’s

Q

What are some tools and techniques to manage threats?

A
  • Detailed study of weather en-route and at the destination
  • Ensuring compliance with operational requirements pertaining to the flight
  • Checking ERSA for arrival at unfamiliar aerodromes for special procedures
  • Thorough and careful pre-flight inspection
  • Self-assessment of fitness, recency and experience required
  • Familiarity with aircraft type and emergency procedures
  • Application of standard operating procedures [SOP].
