DRVSM Program Objectives
Implement DRVSM from FL290-FL410 in the airspace
of the United States, Alaska, the Gulf of Mexico where
the FAA provides air traffic services and possibly the
San Juan FIR.
The United States, Canada, and Mexico are planning
a joint implementation of RVSM.
DRVSM is proposed to be implemented on
January 20, 2005 0901UTC.
NA ATFM April 23, 2003 5
Creates six additional altitudes from FL 290
through FL 410 by the reduction of vertical
separation from 2000 ft. to 1000 ft.
Airspace will be exclusionary for DRVSM
approved aircraft with the exception of
accommodating DoD and Lifeguard aircraft.
Non-DRVSM approved aircraft may transition
through DRVSM airspace.

Automation modifications in progress to support the
visual cue for the controller display to enable a ready
distinction between RVSM approved and non-RVSM
approved aircraft. Note: The visual cue will be applied to non-
RVSM aircraft because it is anticipated that they will comprise less than
5-10% of the flights operating at RVSM altitudes.

States for a simultaneous implementation of RVSM.
Procedural development for bordering ATC facilities.

Tactical Application of RVSM
Tactical RVSM has been applied in other countries.
The second HITL Simulation provided an initial
examination of tactical application of RVSM.
The results were inconclusive but it appeared that
under peak traffic conditions it becomes difficult to
use RVSM tactically.
The third HITL Simulation will further examine the use
of RVSM tactically.
