33 a)
Clearance:
Refers to the space between two objects ✓
There must be sufficient space between the driver and the steering wheel (accept indicators, levers, switches, controls) ✓
To ensure the driver can effectively operate/get in and out of the seat/bus ✓
Reach:
Refers to the range that a person can stretch/move to touch/grasp an object from a specified position ✓
The driver must be able to reach the steering wheel/surrounding instruments from the cockpit ✓
Without it affecting their ability to safely operate/maintain control of the bus ✓
Adjustability:
Refers to the ability of a product to change in size/increase the range of percentiles that a product is appropriate for ✓
The driver’s seat needs to be adjusted to the correct height and distance from the steering wheel for different sized drivers ✓
To enable them to comfortably operate the steering wheel/instruments/bus ✓
Award [1] for each of three distinct points in an explanation of how the design of the driver’s cockpit of a Routemaster bus considers clearance, reach and adjustability.
