Pghbridges.com reports that since the air draft flows toward the river, bicyclists are able to travel through the tunnel in that direction "with little or no effort."

The door is used to control the physical atmosphere within a space by enclosing the air drafts, so that interiors may be more effectively heated or cooled.

Adaptation of existing locks and bridges would be necessary to increase the dimensions to Grand Union Canal gauge, both in width and air draft.

The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.

The air draft is 7 feet when the deck is in the down position, consistent with the passage of barges, and 55 m above the Seine in the upper position.

A rocket stove achieves efficient combustion of the fuel at a high temperature by ensuring a good air draft into the fire, controlled use of fuel, complete combustion of volatiles, and efficient use of the resultant heat.

The baby is secured with a stretchy wrap that goes around the naked torso of the adult, providing the baby with proper support and positioning (maintain flexion), constant containment without pressure points or creases, and protecting from air drafts (thermoregulation).

Cement may be created using a countercurrent kiln where the heat is passed in the cement and the exhaust combined, while the incoming air draft is passed along the two, absorbing the heat and retaining it inside the furnace, finally reaching high temperatures.

This track is judged with respect to at least nine separate criteria given in the Guidelines including under-keel clearance, safe speed, air draft, the use of routing and reporting services (TSS and VTS), and the availability of contingencies in case of emergency.

This wind-down of activity is still continuing, and on January 1 2012, the Haihe will be downgraded from a category I waterway into a category IV, limited to vessels under 1,000 DWT and 10 m of air draft (which will permit the extensive bridge construction planned for the lower Haihe).
