3.12 DISTANCE CRITERIA.
Use Table 3-2 to determine safe distances between parking
areas and fueling operations.
Table 3-2.

Area
Hot Refueling 200 ** 50 *** 200 ** 200
Rapid Defueling 50 50 200 **** 200
NOTE
• For large aircraft (all bombers, all airliners, all transport aircraft carrying more than 20 passengers), the distance
criteria is measured as the closest point between the aircraft FSSZ and building or facility involved. For
small aircraft (fighters, helicopters, utility aircraft, and small transports carrying 20 or less passengers), the
distance criteria is measured as the closest point between the aircraft and building or facility involved. In any
case, a building or facility cannot be inside the FSSZ.
• Hardened Aircraft Shelters/Protective Aircraft Shelters are not considered to be either Inhabited or Uninhabited
Buildings for the purpose or application of this table.
*
For existing parking areas, the distance may be modified on the basis of local conditions, however, the separation distance
shall not be reduced below 50 feet.
**
For E-4B aircraft, the distance from the wingtip can be reduced to 100 feet.
***
Part of an aircraft may pass within 50 feet of a hot refueling operation as long as the operating engine(s) of the taxiing
aircraft do not penetrate the 50-foot criteria.
****
When rapid defueling with an external hydraulic power cart (and no aircraft engine operating) this distance can be reduced
to 100 feet.
