AIRBUS S.A.S. Standard Events 3

1Standard Events

Standard Events A Standard event is one that is detected when its related parameter deviates beyond aspecified limit or a minimum period of time.

Specific Events When a parameter deviates beyond the limit for a period considered to be excessive for theaircraft safety, instead of detecting numerous identical events, a synthetic event called “steady behavior”is detected.

Logical Combination of Events Combination of several events, when Standard or Specific Events aredetected simultaneously a higher hazard level is detected.

4 Speed High in Approach (below 2500ft AFE) SP1000541 - 3.0.0

4 Standard Events AIRBUS S.A.S.

1005 - Speed High in Approach (below 2500ft AFE)

Operational Goal

This event detects if the AC airspeed at 2500ft above the runway (AFE) during approach is above thespecified Deviation Limit speeds.

The Deviation Limits are fixed speeds which can be adjusted for airline policy, and if necessary for specificairfields.

All approaches should be stable by 1000ft AFE (Radio Altitude) which may not be achieved if the ACspeed is high at 2500ft.

1006 - Speed Above VMO

Operational Goal

This event detects if the AC Calibrated Airspeed( _CAS ) exceeds the Maximum Operating Speed limit( _VMO ).

At lower altitudes the aircraft speed is restricted by Airspeed limit _VMO whereas at high altitude, theAC speed can not exceed the Mach limit.

Exceeding _VMO by a large margin can cause structural damage. The event is triggered only in theMedium and High severity levels

6 Speed Above MMO SP1000541 - 3.0.0


1007 - Speed Above MMO

Operational Goal

This event is raised when the AC Mach Number exceeds the Maximum Operating Mach Number ( _MMO).

At high altitude, the AC maximum speed is restricted by the Mach Number limit _MMO whereas at loweraltitudes, the AC speed can not exceed the Maximum Operation Speed _VMO .

The AC can fly close to _MMO in normal operation but auto-thrust normally keeps the speed below thelimit by the flight envelope protection.

Exceeding _MMO by a large amount can cause airframe buffeting and possible AC handling changes.

The _MMO limit can be exceeded slightly in turbulence or in climb/descent at high altitude with largewind component changes, otherwise an _MMO exceedance would indicate an abnormal situation.

The event is only triggered in Medium and High severity levels

10 Speed High in Approach (at 1000ft) SP1000541 - 3.0.0


1010 - Speed High in Approach (at 1000ft)

Operational Goal

Approach speed events monitor the AC airspeed reduction to final approach speed,by checking the airspeedat 3 key altitudes (1000 feet, 500 feet and 50 feet ) with Deviation Limits decreasing from 1000 feet to50 feet.

This event is raised when the AC airspeed is more than 15 kts faster than the approach speed at 1000ft AFE .

One of the parameters for a safe landing requires that the AC decelerates from the higher descent speed toapproach speed well before the runway threshold, and it is Airbus policy that the AC should normally bestabilized at approach speed by 1000ft above the runway or at the latest by 500ft in good weather conditions.

Operational Goal

Approach speed events monitor the AC airspeed reduction to final approach speed, by checking theairspeed at 3 key altitudes (1000 feet, 500 feet and 50 feet ) with Deviation Limits decreasing from 1000feet to 50 feet.

This event detects when the AC airspeed is more than 5 kts below the approach speed at 1000ft AFE .

It is Airbus policy that the AC should normally be stabilized at approach speed by 1000ft above the runwayor at the latest by 500ft in good weather conditions.

An AC with low airspeed at 1000ft may be in a low energy state requiring large thrust corrections possiblyleading to an unstable approach.

Operational Goal

This event detects a rejected take-off above 50 kts( _CAS ).

A crew report of the event is required by most airlines.

The AC can accept repetitive braking at relatively low take-off weights and speeds. Whereas the AC mustalways be capable of stopping from V1, a rejected take-off from high speed and high take-off weights canresult in considerable wear to the wheel brakes and tires.

All rejected take-off should be examined by the operations / safety departments.

SP1000541 - 3.0.0 Braking Delayed at Landing 31


1029 - Braking Delayed at Landing

Operational Goal

This event is raised when the AC deceleration from high speed is slow by comparing the time to decelerate50 kts against the Deviation time limits.

Immediately after main landing gear touch down, reverse thrust is normally selected which decelerates theaircraft the most effectively from high speed, and may be augmented by auto-brake, with manual brakingbeing used at low speed.

Slow deceleration at high speed indicates a delay in reverse thrust selection when it is the most effectiveand thus a possible abnormality. However some operators use minimum reverse to keep brake temperaturesat optimum, and certain airfields prohibit use of max reverse thrust for noise abatement.

The crew may also elect to use minimum reverse and braking if they have to continue to the end of a longrunway after landing.

70 Level Off in Approach below 1400ft (G/S off) SP1000541 - 3.0.0


1311 - Level Off in Approach below 1400ft (G/S off)

Operational Goal

This event detects a level off at an altitude during approach between 1400 feet and 100 feet if the rate ofdescent reduces to less that 300 ft per minute for longer than 10 seconds.

Leveling off during an approach may form part of a type of Non Precision Approach (NPA) procedure thatmay lead to an unstable final descent to the runway, and statistically, unstable final approaches have beeninvolved in a large number of landing accidents.

Generally, "Level Off" NPA procedures are in the process of being replaced with Constant Angleapproaches which allows an ILS like profile. This event detects a levelling off in the approach procedureand allows the operator to investigate the approach.

There may be other factors which caused the crew to level off during the last part of the approach whichmay need investigation.

This event is not active during an ILS approach.

Note that this event has no severity level as it is for information only, and must not be included in riskstatistics .

106 Reversers High Thrust at Low Speed SP1000541 - 3.0.0


1619 - Reversers High Thrust at Low Speed

Operational Goal

This event detects if the thrust reversers are not cancelled at the normal speed during the landing roll.

Thrust reversers are most effective at high speed, and at low speed the hot airflow from the reverser exhaustcan be ingested by engines causing surges, or loud explosions and possible engine damage from the shockand ingestion of foreign objects.

Reverse thrust should therefore be reduced at 70kts towards idle reverse which should be cancelled bytaxi speed of about 25 knots. However in an emergency, full reverse thrust can be kept until the aircrafthas stopped.

Triggering of this event would usually indicate mishandling of reverse thrust, but could indicate anemergency stop.

1624 - Ground Spoilers lever not armed

Operational Goal

This event is triggered when ground spoilers lever is not in armed position prior to take off or landing.Ground spoilers are significant part of deceleration means for rejected take off or landing:

• Ground spoilers participate to lift dumping, by increasing load on wheels, and thus increase wheel-brakes efficiency.

• Increasing aerodynamic drag (+30%), it helps aircraft deceleration.

Note: For Airbus type fitted with steep approach modification, the event is inhibited at landing, if steepapproach push button is on.

110 Thrust Low in Approach (below 500ft RA) SP1000541 - 3.0.0


1701 - Thrust Low in Approach (below 500ft RA)

Operational Goal

This event is raised when the thrust in the final approach below 500ft AFE was too low as shown by the_THR_DEFICIT computed parameter.

The response time of engines at very low thrust may be too long to correct the flight path if a rapid increasein thrust is needed late in the approach.

For this reason approaches should be stabilized below 1000ft at the correct airspeed and engine thrust.

Low thrust on approach is normally associated with fast and possibly unstable approaches

Operational Goal

This event detects if the thrust is reduced late ( below 10ft ) during landing, both with and without activeAutothrust.

A hard or bounced landing can result if the thrust is not reduced at the correct rate and height above therunway. It may affect the landing distance performance.

If the thrust levers are not retarded to Idle the Autothrust will still be operative and as the aircraft is flaredand the speed tends to decrease this will cause an increase in thrust. An increase in thrust during the flarewill cause an increase in flare distance with its associated hazards.

SP1000541 - 3.0.0 Dual Stick Inputs 153


1917 - Dual Stick Inputs

Operational Goal

This event detects occurrences of sidestick deflection occurring from both side sticks at the same time(beyond thresholds in roll or pitch axis) that could affect aircraft trajectory or altitude beyond the path asintended by the PFs inputs. Dual inputs can also cause the PF to be out of the aircraft control loop. Theaircraft is designed to be flown manually by one pilot and double stick inputs should not occur.

The thresholds used in the aircraft dual stick input logic have resulted from design and testing to representthe amount of significant sidestick inputs needed to start potentially unsafe trajectory changes. HenceAirFASE needs to monitor this same risk to safe flight.

It is not the intent of this event to monitor SOPs. Therefore for cases where the take-over button is used bythe PNF, then event reset conditions are applied (ie. no event is triggered or the event triggering conditionis reset if it was previously triggered)
