Abstract

Datalink connectivity allows information transfer between ground staff and aircraft. Several uplinks are sent by Airline's Operational Control (AOC) to the aircraft's pilot. Under normal operation, uplink messages are processed by a Flight Management System (FMS) computer and displayed. The uplink messages which cannot be immediately processed get stored in a buffer until they meet the criteria for processing, which may include pilot action. Since buffered uplinks are not presented to the pilot when criteria remains unmet, the pilot is unaware of the uplink messages that are waiting for pilot action. At times, the pilot may unwittingly request the same uplink message repeatedly without realizing that a buffered uplink message requires pilot action. Unless the pilot action is completed for the buffered uplink message, related uplink messages stored in the buffer cannot be displayed. More uplink messages arrive and are buffered until the storage capacity is full, causing pilot confusion when none of the uplink messages are visible. The proposed solution provides the pilot with diagnostic page which include cue/indicators of the uplink message in the buffer. The diagnostic page indicates what pilot actions are necessary to release the buffered messages for processing. By performing the actions on the diagnostic page, the uplink messages are processed in intended manner, leading to smoother operation and reduced workload for both the pilots and the ground staff.

ABSTRACT

Datalink connectivity allows information transfer between ground staff and aircraft.

Several uplinks are sent by Airline’s Operational Control (AOC) to the aircraft’s pilot.

Under normal operation, uplink messages are processed by a Flight Management

System (FMS) computer and displayed. The uplink messages which cannot be

immediately processed get stored in a buffer until they meet the criteria for

processing, which may include pilot action. Since buffered uplinks are not

presented to the pilot when criteria remains unmet, the pilot is unaware of the uplink

messages that are waiting for pilot action. At times, the pilot may unwittingly request

the same uplink message repeatedly without realizing that a buffered uplink

message requires pilot action. Unless the pilot action is completed for the buffered

uplink message, related uplink messages stored in the buffer cannot be displayed.

More uplink messages arrive and are buffered until the storage capacity is full,

causing pilot confusion when none of the uplink messages are visible. The

proposed solution provides the pilot with diagnostic page which include

cue/indicators of the uplink message in the buffer. The diagnostic page indicates

what pilot actions are necessary to release the buffered messages for processing.

By performing the actions on the diagnostic page, the uplink messages are

processed in intended manner, leading to smoother operation and reduced

workload for both the pilots and the ground staff.

1. INTRODUCTION

The Flight Management System (FMS) provides primary navigation, flight planning,

optimized route determination and en route guidance for the aircraft. The FMS is

connected to navigation sensors, engine and fuel system, flight control system, and

surveillance systems. The FMS receives flight path instructions from the Airline’s

Operational Control (AOC) via datalink. The datalink between the FMS and the AOC

allows communication between the pilot and the ground staff. Some of the important

messages transmitted from the ground staff can include, but are not limited to, flight

uplink/downlink messages, takeoff loading uplink/downlink messages, performance

uplink/downlink messages and wind data uplink/downlink messages. Currently, the FMS

receives uplink messages and they are stored in a queue for processing in a buffer. The

uplink messages which cannot be immediately processed get stored in a buffer until

they meet a criteria for processing, which may include pilot action. Since buffered

uplinks are not presented to the pilot when criteria remains unmet, the pilot is unaware

of the uplink messages that are waiting for pilot action. The pilot needs to take action on

the buffered uplink message to meet criteria for viewing and processing related uplink
