Chocking <strong>of</strong> <strong>Aircraft</strong><br />

• Chocks should be <strong>of</strong> a high visibility colour <strong>and</strong> be identified by high visibility<br />

markings.<br />

• Chocks should be triangular in shape; with an approximate 45º angle at the<br />

corners.<br />

• Chocks should be made <strong>of</strong> a material that has a suitable coefficient <strong>of</strong> friction <strong>and</strong><br />

that has adequate rigidity.<br />

• The length <strong>of</strong> the chock should be such that is covers the full with <strong>of</strong> the wheel(s)<br />

required to be chocked.<br />

• The height <strong>of</strong> the chock should be in relation to the size <strong>of</strong> the wheel <strong>and</strong> the type<br />

<strong>of</strong> tyre.<br />

• Chocks should be stored in a dedicated area so that they are not the cause <strong>of</strong><br />

FOD.<br />

• Personnel should be made aware <strong>of</strong> dangerous areas in the vicinity <strong>of</strong> the aircraft<br />

wheels, such as hot brakes <strong>and</strong> protrusions, gear doors <strong>and</strong> antennae which could<br />

cause injury.<br />

• Chocks should be positioned on an aircraft according to airframe manufacturer<br />

recommendations.<br />

• Chocking <strong>of</strong> the aircraft main gear should be achieved by positioning the chocks<br />

in the front <strong>and</strong> rear <strong>of</strong> the outboard tires.<br />

• Placing <strong>of</strong> chocks on an arriving aircraft must only be performed after engine<br />

spool down, anti-collision lights switched <strong>of</strong>f <strong>and</strong> clearance to approach the<br />

aircraft is given by the responsible person.<br />

• Chocks, when positioned, should be parallel to the wheel axle <strong>and</strong> only lightly<br />

touching the tyres.<br />

• In the event <strong>of</strong> high wind conditions, additional chocking <strong>and</strong> other measures<br />

may have to be taken to secure the aircraft.<br />

• Chocks should not be removed from an aircraft until clearance is given by the<br />

responsible person.<br />
