A major benefit that should accrue from ATM developments is the implementation of “free flight” services. The ultimate goal is to offer aircraft a straight track from departure point to destination. This will be compromised still by terminal-area procedures at airports, which must respect the runway direction(s) in use. In some countries there is already considerable progress with continuous-decent-approach (CDA) operations allowing considerable descent and landing-fuel savings. Also reduced vertical separation minima (RVSM) are being introduced in areas of the upper airspace, and by reducing the once-obligatory 2,000-foot separation minimum between opposing directions traffic above FL290 (flight level equivalent to 29,000 feet) to 1,000 feet, there is consistent vertical separation throughout controlled airspace and an approximate 100 percent of additional cruise-level capacity. This benefit has arisen largely from the improvement in onboard sensing of vertical position on modern aircraft and is not directly attributable to ground systems improvements.

Emerging from research into implementation in recent years has been an ATM-originated concept called collaborative decision making (CDM). Airports can be affected by operational circumstances that affect capacity, for example:
