  Ground Signals
  at Aerodromes


     

Landing Prohibited
 
Special Precautions
   
A red square panel with yellow diagonals denotes the aerodrome is unsafe and landing there is prohibited.  
A red square panel with one yellow diagonal denotes that the manoeuvring area is poor and special care is needed when landing.
   

   
Use only hard surfaces for take-off and landing   Use hard surface at all times   Right-hand circuit
   
A white dumb-bell with black stripes at right angles t othe shaft denoyes taking off and landing shall be on hard surfaces but ground movement is not so restricted.   A white dumb-bell denotes that the movement of aeroplanes and gliders on the ground is confined to hard surfaces only.   A red and yellow striped arrow along two sides of the signal area and pointing clockwise denotes a right-hand circuit is in force. (A rectangular green flag on the mast has the same meaning as this signal.)

   
Gliding    
     
A double white cross denotes gliding is in progress. A similar but much larger signal is used to mark the area on the aerodrome to be used only by gliders. Two red balls on the mast has the same meaning.  

A yellow cross denotes the tow-rope dropping area.


Direction of Take-off and Landing
   
A white "T" denotes the direction of take-off and landing towards the cross-piece of the "T" unless otherwise authorised by ATC.  

A white disc ahead of the "T" cross-piece indicates that take-off and landing directions may not necessarily coincide. A single black ball on the mast has the same meaning.


Landing Area for Light Aircraft    
 

   
A white letter "L" denotes a part of the manoeuvring area which shall be used only for the take-off and landing of light aircraft.  

A red letter "L" across a white dumb-bell denotes that light aircraft can use runways or areas marked by the white "L".

   

Helicopter Operations    
 

   
A two-metre high white letter "H" in the signals area denotes that helicopters can only take-off and land in a designated area.  

A six-metre high white letter "H" denotes that area.

   

Runway Indication  

Aerodrome Control in Operation

 

Reporting Point

 

 

Two-figure black numerals on a yellow background denote the runway in use.  

A chequered red / yellow  flag on the mast denotes that aircraft can only move on the apron and within the manoevring area with the permission of ATC.

 

A black "C" on a yellow  background denotes the reporting point.


Unserviceable portion of Runway/taxiway    
   
Two or more white crosses at 45 degrees to the centre line and not more than 300 metres apart denote the section so marked as unfit for aircraft movement.    

Boundaries    
   

Markers/Flags with orange / white stripes are used to mark boundaries of unfit areas. They can also indicate aerodrome boundaries.


Military  / Disused Aerodromes
 

A red letter "L" denotes that light aircraft may land on a special area shown by white corner markings.  

A white cross displayed at the end of the runway denotes that landing is dangerous

         
 

 

A white cross and a single white bar at the end of a runway on a disused aerodrome denotes fitness to land in an emergency only.  

Yellow and black triangular solid sections denote areas unserviceable due to bad ground, the presence of working parties, stationary vehicles or other obstructions.

 

Two vertical yellow bars on a red square indicate landing areas are serviceable but normal facilities are not available. Land in an emergency only.

         
 

A red flag on the mast denotes a left-hand circuit.

A green flag on the mast denotes a right-hand circuit.
