 | Permits to Fly are authorisations granted to aircraft such as homebuilts, vintage aeroplanes, warbirds and some simple classic light aircraft which are not required to meet the standards demanded for a full C of A, and are accordingly restricted in the kinds of operation for which they may be used. |
| Aircraft control systems in which pilots' control inputs are transmitted to control surfaces electronically or via fibre optics rather than by mechanical linkage. |
| Aircraft structural load limits are expressed in positive and negative values, the positive limit usually greater than negative, except in specialist aerobatic types. |

| For some systems (such as the B-52 bomber and KC-135 refueling aircraft) that continue to be used many years beyond their expected service life, operating and support costs can amount to a higher percentage of life-cycle costs. |
| Systems under development are expected to have projected life-cycle costs 20 to 50 percent lower than the actual costs of the systems they are replacing.3 The actual operating and support costs for fielded systems are expected to be reduced 20 percent by fiscal year 2005. |
| We reviewed efforts by new aircraft programs to lower operating and support costs, including those of the Air Force variant of the Joint Strike Fighter, which is to replace the F-16 and the A-10; the F-22, to replace the F-15; and the variant of the Joint Primary Aircraft Training System, to replace the T-37B. |
