Pilot Equipment Interface
From SKYbrary Wiki
Level busts are often the result of break-down of the pilot-equipment interface; that is to say, the correct handling or interpretation of aircraft equipment by the pilot. There are usually two elements to this:
- The pilot makes an incorrect setting or performs an inappropriate action on the equipment; and,
- The error is not noticed or not corrected by other flight-crew members.
- Altimeter Setting Procedures. The pilots set an incorrect or inappropriate pressure setting on the altimeter barometric sub-scale;
- Use of the Altitude Alerter. The pilots inadvertently select the wrong altitude or flight level on the altitude alerter;
- Use of the Autopilot.
- The pilot enters an incorrect target altitude on the Flight Guidance System and fails to confirm the entered target on the Primary Flight Display and/or the Navigation Display;
- The pilot inadvertently arms a selected mode or selects an incorrect mode;
- The pilots become pre-occupied with the automatic systems resulting in loss of situational awareness;
- The existence and application of effective Standard Operating Procedures covering cross-checking and monitoring procedures.
- Improved Crew Resource Management in order to ensure that any error made in setting or operating aircraft equipment is corrected before being implemented.
