In the prior post a Design Aircraft is defined to be an element of the Airport Reference Code. As noted, it is a typical aircraft expected to operate at an airport. By no means is it the largest aircraft a facility can accommodate, but, a typical aircraft. Nearly every jet on this chart could conceivably use an expanded Solberg Airport.
The runway requirements chart, prepared by a professional aviation planning company, shows overlay indicating the existing 3,000 ft. paved runway length and the proposed 5,000 ft. runway length approved in the Solberg Airport Master Plan. Additionally, the Design Aircraft, equivalent to the Citation 550*, is noted as fourth up from the bottom.
This chart documents at least eight aircraft that can operate on the proposed 5,000 ft. runway and three more that are very close. More than half are larger than the Design Aircraft! There can be no doubt a 5,000 ft. runway is intended to allow larger faster aircraft to safely use the developed Solberg Airport. The longer runway is not primarily intended to afford improved safety to existing users of the airport as has been stated.
It is noteworthy that according to this data neither the Citation Mustang nor the Citation 550 should be accommodated by the existing 3,000 ft. paved runway at Solberg, but, they are known to operate from the facility. By this standard all except one of the large jets, all of the long range jets, all of the midsize jets and all of the light and very light jets can use Solberg Airport after development.
* The Citation Encore is a recent model based on the older Citation 550 Design Aircraft specified in the Solberg Airport Master Plan.
