What is remote monitoring?

Watching the state of the airfield lighting from a control room or off-site — so faults, alarms and trends are seen without a visit to every location.

The Fact Future technology

Remote monitoring is watching the state of the airfield lighting from a place away from the equipment, such as a control room or an off-site centre. Status from CCRs, circuits, signs and PAPI is collected, sent over a secure link and shown in the ALCMS as live status, alarms and trends.

It lets problems be seen sooner and visits be planned, rather than waiting for a night inspection. But it is viewing, not controlling: sending commands is a separate function with its own approval and safeguards. The link needs cyber-security, a lost link or a false alarm can mislead, and an engineer confirms an alert on site before acting. It supports the maintenance programme and does not replace it.

  1. Collect. Equipment reports its state: CCR output, circuit status, and sign or PAPI health where fitted.
  2. Transmit. Status travels over the site network through a secure, access-controlled gateway.
  3. View. The ALCMS shows live status, an event log and trends to the people who need them.
  4. Alert. An alarm reaches the right person, ranked so important faults are not buried.
  5. Act. The engineer plans a focused visit and confirms the fault on site.
  6. Confirm. After the fix, the status shows the equipment is healthy again.
Purpose See the state of the lighting from a distance, sooner and without a visit to each location
Core job Collect, send and show status, alarms and trends; it does not itself switch or repair anything
Needs Equipment that reports its state, a site network, a secure gateway and a control-system display
Key idea Equipment reports; the system shows; people confirm and decide
Limits Link loss, delayed or wrong data, alarm overload, remote-access security

Remote monitoring

Shows the state of the lighting from a distance, so faults and trends are seen sooner. It views; it does not command.

Local inspection only

Status is known only when someone is at the equipment. Faults wait for the next inspection or a report from pilots.

Schematic — simplified for clarity. Features, data points and communication methods vary by supplier and site. Monitoring, inspection, testing and maintenance requirements are set by ICAO Annex 14, FAA AC 150/5340-26 where applied, the national regulator and the aerodrome’s approved procedures.

Frequently Asked Questions

Q1What is remote monitoring in airfield ground lighting?

Watching the state of the airfield lighting from somewhere other than the equipment itself, such as a control room or an off-site centre. Status, alarms and trends are collected from CCRs, circuits and fixtures and shown through the ALCMS, without a visit to each location.

Q2Is remote monitoring the same as remote control?

No. Monitoring is seeing the state; control is sending commands such as switching or changing intensity. They are separate functions, and control from outside the aerodrome needs its own approval, access limits and safeguards.

Q3What can be monitored remotely?

Typically CCR on or off state, brightness step, output current and alarms, circuit and lamp-out status, and on smart equipment the state of individual signs, PAPI units or lights. What is available depends on the equipment and the system.

Q4How does the information get to the viewer?

Equipment status reaches the ALCMS over the site’s communication network. Remote viewers connect through a secure gateway. The links, protocols and access rules vary by site and must meet the aerodrome’s cyber-security requirements.

Q5What are the limits of remote monitoring?

A link can fail, data can be wrong or delayed, and too many alarms can hide the important ones. Remote access is a security risk if not controlled. A reading is a prompt to check, not proof of what is on the airfield.

Q6Does it replace inspection and maintenance?

No. Inspection, cleaning, electrical tests and the other required checks still follow ICAO Annex 14, the national regulator and the aerodrome’s approved procedures. Monitoring helps find faults sooner and plan visits, and an engineer confirms an alert before acting.
