Description
An autopilot is a device used to guide an aircraft without direct assistance from the pilot. Early autopilots were only able to maintain a constant heading and altitude, but modern autopilots are capable of controlling every part of the flight envelope from just after take-off to landing. Modern autopilots are normally integrated with the flight management system (FMS) and, when fitted, the autothrottle system.
Autopilot software, which is integrated with the navigation systems, is capable of providing control of the aircraft throughout each phase of flight. If an autothrottle/autothrust system is installed, the appropriate thrust may be automatically set during take-off, and is then adjusted automatically as the climb progresses, while the aircraft climbs at the appropriate speed for its mass and ambient conditions. The aircraft then levels at the required altitude or flight level while the power is adjusted to achieve and maintain the programmed speed. At the same time, the aircraft follows the flight plan route. If an autothrottle is not installed, the pilot must make all power adjustments appropriate to the autopilot mode and phase of flight.
On commencing the descent, the power is adjusted and the aircraft descends at the appropriate speed and on the required routing, leveling as required in accordance with the flight clearance until the approach is commenced. If this is to be a Category III Instrument Landing System (ILS) approach with Autoland, the autopilot controls the aircraft flight path so that it follows the ILS glide path and localiser, adjusting the power to maintain the appropriate speed and commencing the flare as required to achieve a safe landing without the runway being visible until the final stage of the approach. On some aircraft, the autopilot can then guide the aircraft so that it maintains the runway centre-line until it stops.
At any stage of the flight, the pilot can intervene by making appropriate inputs to the autopilot or the FMS. In an emergency, the pilot can disengage the autopilot and take over manual control, usually by pressing a switch mounted conveniently on the control column (although alternative means of disengaging the autopilot are available). Modern aircraft have another switch or throttle position which allows the pilot to change instantly from approach to go-around mode if necessary. If the aircraft is not fitted with an automatic go-around function, pilots must disconnect the autopilot and fly the missed approach manually.
The safe and efficient operation of automatic systems relies on clear understanding of the capabilities and the design philosophy of the equipment. Failure to achieve this level of understanding has resulted in several fatal accidents.

Accidents and Incidents
The following events involved airworthiness issues associated with the autoflight system:
On 19 February 2024, a relatively experienced UAV pilot lost control of a ST Engineering Aerospace DrN-355LS whilst operating it on a Beyond Visual Line of Sight (BVLOS) flight about one mile over water from their Sentosa Island location. A brief interruption of the Global Navigation Satellite System (GNSS) signal required the pilot to take control manually. But when the attempt to do so did not follow the correct procedure within the allowed five seconds, control was lost and the UAV ditched and sank and was not recovered. Improvements to pilot access to manual control reversion and related training were recommended.
On 4 March 2024, a Boeing 737-800 departing Bristol took longer than expected to become airborne and passed over the end of the runway at approximately 10 feet. It was then initially unable to climb at a speed much above V2 until it was recognised that the thrust set was significantly below that intended. Despite the flight being used for new captain line training, a check at 80 knots that correct thrust was set did not occur. The fact that the autothrottle had not been successfully re-engaged after it dropped out when takeoff thrust was being set went unrecognised.
On 18 October 2019, a Boeing 787-9 descending to 4,500 feet to join the ILS for runway 25R at Hong Kong at 15 nm from touchdown failed to establish on the localiser. The autopilot was disconnected and the aircraft manually positioned onto the localiser from the north, establishing at 12 nm with terrain proximity not sufficient to activate the EGPWS. It was found that the deviation was attributable to an anomaly in the aircraft type Autopilot Flight Director System, and a corresponding Alert Service Bulletin was issued by Boeing to replace the faulty system component.
On 5 April 2019, a Boeing 737-500 crew declared an emergency shortly after departing Madrid Barajas after problems maintaining normal lateral, vertical or airspeed control of their aircraft in IMC. After two failed attempts at ILS approaches in unexceptional weather conditions, the flight was successfully landed at a nearby military airbase. The Investigation found that a malfunction which probably prevented use of the Captain’s autopilot found before departure was not documented until after the flight but could not find a technical explanation for inability to control the aircraft manually given that dispatch without either autopilot working is permitted.
On 9 January 2021, a Boeing 737-500 was climbing though 10,700 feet less than five minutes after departing Jakarta in daylight when it began to descend at an increasing rate from which no recovery occurred and 23 seconds later was destroyed by sea surface impact killing all 62 occupants. The Investigation concluded that the departure from controlled flight was unintentional and the result of the pilots’ inattention to their primary flight instruments when, during a turn with the autopilot engaged, an autothrottle malfunction created apparently unrecognised thrust asymmetry which culminated in a wing drop and a consequent loss of control.
On 20 July 2011, the flight crew of a Swiss European Avro RJ-100 on a positioning flight from Nuremburg to Zurich responded inappropriately to an unexpected ‘bank angle’ alert in IMC. Near loss of control followed during which a PAN was eventually declared. The situation was resolved by a belated actioning of the QRH checklist applicable to the failure symptoms experienced. The subsequent investigation attributed the event to inappropriate crew response to a failure of a single IRU and poor manual flying skill whilst the situation was resolved.
On 3 July 2017, an Airbus A319 sustained significant landing gear damage during the First Officer’s manual landing at Munich which recorded a vertical acceleration exceeding the threshold for a mandatory airworthiness inspection. That inspection found damage to nose and one main landing gear legs and, following Airbus advice, all three were replaced before release to service. The Investigation was unable to explain why neither pilot detected the incorrect pitch attitude and excessive rate of descent in time to take corrective action and noted that a reversion to manual flight during intermediate approach had been due to a technical malfunction.
On 25 May 2016, an Embraer ERJ 190 experienced a major electrical system failure soon after reaching its cruise altitude of FL 360. ATC were advised of problems and a descent to enable the APU to be started was made. This action restored most of the lost systems and the crew, not having declared an emergency, elected to complete their planned 400nm flight. The Investigation found that liquid contamination of an underfloor avionics bay had caused the electrical failure which had also involved fire and smoke without crew awareness because the smoke detection and air recirculation systems had been unpowered.
On 15 October 2015 a Boeing 747-300 experienced significant vibration from one of the engines almost immediately after take-off from Tehran Mehrabad. After the climb out was continued without reducing the affected engine thrust an uncontained failure followed 3 minutes later. The ejected debris caused the almost simultaneous failure of the No 4 engine, loss of multiple hydraulic systems and all the fuel from one wing tank. The Investigation attributed the vibration to the Operator's continued use of the engine without relevant Airworthiness Directive action and the subsequent failure to continued operation of the engine after its onset.
On 29 February 2016, control of a 50 kg, 3.8 metre wingspan UAV was lost during a flight test being conducted in a Temporary Segregated Area in northern Belgium. The UAV then climbed to 4,000 feet and took up a south south-westerly track across Belgium and into northern France where it crash-landed after the engine stopped. The Investigation found that control communications had been interrupted because of an incorrectly manufactured co-axial cable assembly and a separate autopilot software design flaw not previously identified. This then prevented the default recovery process from working. A loss of prescribed traffic separation was recorded.
On September 13 2008, at night and in good visual conditions*, a Boeing 737-500 operated by Aeroflot-Nord executed an unstabilised approach to Runway 21 at Bolshoye Savino Airport (Perm) which subsequently resulted in loss of control and terrain impact.
On 26 April 1994, the crew of an Airbus A300-600 lost control of their aircraft on final approach to Nagoya and the aircraft crashed within the airport perimeter. The Investigation found that an inadvertent mode selection error had triggered control difficulties which had been ultimately founded on an apparent lack understanding by both pilots of the full nature of the interaction between the systems controlling thrust and pitch on the aircraft type which were not typical of most other contemporary types. It was also concluded that the Captain's delay in taking control from the First Officer had exacerbated the situation.
On 22 October 2005, a British Airways Airbus A319 climbing en route to destination over south east England at night in VMC experienced a major but temporary electrical failure. Most services were re-instated within a short time and the flight was continued. However, during the subsequent Investigation, which took over two years, a series of significant deficiencies were identified in the design of the A320 series electrical system and the manufacturer-recommended responses to failures in it and in response, Airbus developed solutions to most of them.
Events in the SKYbrary database which include AP/FD and/or ATHR status awareness as a contributory factor:
On 4 December 2023, a Boeing 737-8200 crew misjudged positioning onto the ILS approach for arrival at London Stansted. Having decided to go around, they then continued to climb above the 3,000-foot missed approach altitude, which they had failed to set until alerted by the controller. The descent following a 1,000 feet level bust then continued back through the missed approach altitude at almost 9,000 fpm with an EGPWS ‘PULL UP’ warning just as recovery from 1,740 feet agl was initiated. After levelling at 3,000 feet, radar vectoring onto the ILS was provided with the approach then completed normally.
On 6 November 2018, an Airbus A340-600 in cruise northbound over the Swiss Alps received an overspeed warning after encountering an unexpected wind velocity change. However, the crew failed to follow the prescribed response procedure. This led initially to a climb above their cleared level, and further inappropriate actions were then followed by PAN and MAYDAY declarations as control of the aircraft was briefly lost in a high-speed descent below their cleared level. The operator subsequently enhanced pilot training realism by providing it in a simulator configured for the aircraft variant operated by the company. The operator also introduced upset recovery training.
On 28 January 2019, an Airbus A320 became unstabilised below 1000 feet when continuation of an ILS approach at Muscat with insufficient thrust resulted in increasing pitch which eventually triggered an automatic thrust intervention which facilitated completion of a normal landing. The Investigation found that having temporarily taken control from the First Officer due to failure to follow radar vectors to the ILS, the Captain had then handed control back with the First Officer unaware that the autothrust had been disconnected. The context for this was identified as a comprehensive failure to follow multiple operational procedures and practice meaningful CRM.
On 4 February 2020, an Airbus A350-900 initiated a go around from its destination approach at 1,400 feet aal following a predictive windshear alert unsupported by the prevailing environmental conditions but the First Officer mishandled it and the stop altitude was first exceeded and then flown though again in a descent before control as instructed was finally regained four minutes later. Conflict with another aircraft occurred during this period. The Investigation concluded the underlying cause of the upset was a lack of awareness of autopilot status by the First Officer followed by a significant delay before the Captain took over control.
On 1 June 2019, a Boeing 737-800 was instructed to go around after it was observed to be significantly below the vertical profile for its RNAV approach as it reached the procedure minimum descent altitude. Having then climbed less than 300 feet, the aircraft began to descend, reaching 457 feet agl before resuming its climb. The Investigation found that the terrain proximity on approach followed a failure to discontinue a comprehensively unstable approach and the terrain proximity episode during the go around was due to continued following of the Flight Director which was providing guidance based on incorrect mode selections.
On 23 February 2019, a Boeing 767-300 transitioned suddenly from a normal descent towards Houston into a steep dive and high speed terrain impact followed. The Investigation found that after neither pilot had noticed the First Officer’s inadvertent selection of go around mode during automated flight, the First Officer had then very quickly responded with an increasingly severe manual pitch-down, possibly influenced by a somatogravic illusion. He was found to have had a series of short air carrier employments terminating after failure to complete training, had deliberately and repeatedly sought to conceal this history and lacked sufficient aptitude and competency.
On 20 August 2011, a First Air Boeing 737-200 making an ILS approach to Resolute Bay struck a hill east of the designated landing runway in IMC and was destroyed. An off-track approach was attributed to the aircraft commander s failure to recognise the effects of his inadvertent interference with the AP ILS capture mode and the subsequent loss of shared situational awareness on the flight deck. The approach was also continued when unstabilised and the Investigation concluded that the poor CRM and SOP compliance demonstrated on the accident flight were representative of a wider problem at the operator.
On 6 July 2013, an Asiana Boeing 777-200 descended below the visual glidepath on short finals at San Francisco after the pilots failed to notice that their actions had reduced thrust to idle. Upon late recognition that the aircraft was too low and slow, they were unable to recover before the aircraft hit the sea wall and the tail detached. Control was lost and the fuselage eventually hit the ground. A few occupants were ejected at impact but most managed to evacuate subsequently and before fire took hold. The Probable Cause of the accident was determined to be the mismanagement of the aircraft by the pilots.
On 22 May 2020, an Airbus A320 made a high-speed unstabilised ILS approach to runway 25L at Karachi, Pakistan, and did not extend the landing gear for touchdown. It continued along the runway, skidding on both engines before getting airborne again with the crew announcing their intention to make another approach. Subsequently, both engines failed due to the damage sustained. The aircraft crashed in a residential area near the airport and was destroyed by impact forces and a post-crash fire. Ninety-seven of the 99 occupants died, and four persons on the ground were injured with one subsequently dying.
On 11 January 2018, a Bombardier DHC8-400 departed Belfast City with incorrectly-set Flight Director (FD) modes and the Autopilot was then engaged without either pilot noticing that the aircraft was not being flown in accordance with the FD command bar or that the aircraft had then begun to descend. The rate of descent increased unnoticed and reached 4,300 fpm before recovery from a 928 feet minimum height after EGPWS 'DON'T SINK' and 'PULL UP' annunciations. The Investigation found that no target altitude had been entered and noted failure to follow normal operating procedures including on the use of checklists.
On 28 October 2007, a Boeing 737-800 under the command of a Training Captain occupying the supernumerary crew seat touched down off an ILS Cat 1 approach 870 metres short of the runway at Katowice in fog at night with the AP still engaged. The somewhat protracted investigation did not lead to a Final Report until over 10 years later. This attributed the accident to crew failure to discontinue an obviously unstable approach and it being flown with RVR below the applicable minima. The fact that the commander was not seated at the controls was noted with concern.
On 9 December 2016, a Bombardier DHC8-400 departing Sydney lost prescribed separation against an inbound Boeing 777-200 after its crew failed to ensure that the aircraft levelled as cleared at 5,000 feet and this was exceeded by 600 feet. The Investigation found that the First Officer, as Pilot Flying, had disconnected the autopilot prior to routinely changing the selected airspeed because it tended to disconnect when this was done with altitude capture mode active but had then failed to re-engage it. The Captain's lack of effective monitoring was attributed to distraction as he sought to visually acquire the conflicting traffic.
On 20 October 2013, a Boeing 757-200 Co-Pilot believed his aircraft was at risk of stalling when he saw a sudden low airspeed indication on his display during a night descent and reacted by increasing thrust and making abrupt pitch-down inputs. Other airspeed indications remained unaffected. The Captain took control and recovery to normal flight followed. The excursion involved a significant Vmo exceedance, damage to and consequent failure of one of the hydraulic systems and passengers and cabin crew injuries. The false airspeed reading was attributed by the Investigation to transient Ice Crystal Icing affecting one of the pitot probes.
On 4 June 2002, the crew of an MD82 in the cruise at FL330 with AP and A/T engaged failed to notice progressive loss of airspeed and concurrent increase in pitch attitude as both engines rolled back to thrust levels which could not sustain level flight. The aircraft stalled and a recovery was accomplished with significant altitude necessary before engine thrust was restored and a diversion made. The Investigation attributed the engine rollback to ice crystal icing obstructing the engine inlet pressure sensors following crew failure to use the engine anti-icing as prescribed. Two Safety Recommendations were made.
On 3 August 2016 a Boeing 777-300 rejected a landing at Dubai from the runway following a late touchdown after floating in the flare. It then became airborne without either pilot noticing that the A/T had not responded to TO/GA switch selection and without thrust, control was soon lost and the aircraft hit the runway and slid to a stop. The Investigation found that the crew were unfamiliar with the initiation of a go around after touchdown and had failed to follow several required procedures which could have supported early recovery of control and completion of the intended go around.
