What SMEGCS stands for?
Surface Movement Guidance and Control System
What is the purpose of the SMEGCs control system?
To ensure the safe movement of aircraft and vehicles on taxiways using visual aids and control procedures during low visibility conditions.
What are the three levels of SMEGs in the U.S. based on RVR?
- < 1,200 ft to 500 ft RVR,
- < 500 ft to 300 ft RVR,
- < than 300 ft.
What guidance exists for taxiing below RVR 300?
There is no guidance; it is at the discretion of the airport operator.
What are some key visual aids used in SMEGCS?
- Taxiway centerline lighting, - Markings,
- Signage,
- Runway guard lights, and
- Stop Bar lighting.
Internationally what is the equivalent US SMEGCS?
US SMEGs is associated with (LVO),
- While internationally, it is (LVP) or A-SMEGs.
What happens when weather is forecasted to drop below 1200 RVR?
ATC contacts the airport authority,
Which inspects required lighting systems and signage.
What happens when weather is forecasted to drop below 1200 RVR?
ATC contacts the airport authority,
Which inspects required lighting systems and signage.
Is the implementation of an LVO SMEGs plan mandatory for all airports?
No, it is encouraged by the FAA but is at the discretion of the airport operator.
Why is it important to review the SMEGs chart at each airport?
Because SMEGCS plans can vary from airport to airport.
What characteristics distinguish taxiway centerline markings on SMEGCS routes?
- They are painted with highly reflective yellow paint,
- are 12 inches wide, and
- include black borders.
What are the two types of runway guard lights in SMEGCS?
Both flashing yellow lights:
- Elevated and
- in-pavement,

Which of the following is true regarding SMGCS in the US?
You can’t assume that the SMGCS plan will be the same from airport to airport. Special attention must be placed on reviewing the SMGCS chart for each airport to determine what their plan entails.
Access to runways under SMGCS operations below RVE 500 is controlled by what?
In addition to clearance from ATC…
Access to runways under SMGCS operations below RVR 500 is controlled by:
- a stop bar,
- a row of red unidirectional in-pavement lights installed at the runway holding position.
