The Richmond International Airport parking shuttle fleet used a combination of primary fueling through the time fill system and backup fueling through cascade fast fill to fill its fleet of cutaway van buses.

Time fill provides several advantages for fleets that are parked overnight in the yard:

1. Time fill often reduces the size of compression equipment required
2. This results in lower capital, power and maintenance costs
3. Time fill systems are very simple and thus are very reliable
4. Time fill provides a very complete vehicle fills without high technology fill algorithms
