VNAV Procedure – The VNAV procedure within TERPS® has been modified for FAA Order 8260.54A. The trapezoid is now smaller. Be advised the FAA is still using the old cancelled criteria. This means, like the LNAV, the FAA may respond that your site is located within the LNAV/VNAV area. If this occurs please request a restudy under the new criteria.
Google Earth: Airspace® and TERPS® have been upgraded to seamlessly add Google Earth to their capability. From the Data Input Module in Airspace® or the SetPoint Window within TERPS®, you can launch Google Earth and plot your point with an information balloon.
Airway Route: Using the information produced by Airspace concerning low altitude airways, you can now accurately display the segment of the airway your site is located. Use the ‘Route Tool’ new from the ‘Draw Menu’.
Initial Approach Fix (IAF): Use the ‘Route Tool’ to construct the route between the Initial Approach Fix (IAF) and the FAF. Apply a ROC of 1000′ between the Initial Fix andthe Intermediate Fix (IF) and 500′ between the IF and the FAF.
Critical Area: The Critical Area of a Glide Slope (GS) and Localizer (LOC) as identified in FAA Order 700.2F can now be analyzed. The ability to expand the area with magnification is also available. The LOC Critical Area is based upon the ILS Category. The additional capability of displaying the Fresnel Zone reflection area is available.
Runway Protection Area: The RPZ is becoming more critical each day. This area can be analyzed for impact. Also, the Runway Obstacle Free Area and Extension identified in AC 150/5300-13 CHG12 is now available. If the RPZ extends onto private property, it is an advisory. It cannot be made mandatory. Many airport managers do not understand this and will fight your proposed structure.
Visual Guidance Slope Indicator (VSGI) Obstacle Clearance Surface (OCS): The VSGI OCS is an electro-optic device to keep a pilot on the correct approach path. This surface extends 4 Nautical Miles (NM) and has a clearance angle of 1.5° to 1.83°. The VSGI OCS analysis capability for a VASI, PAPI and PLASI has been increased. The ability to calculate the exact OCS value is based upon the location of the equipment, not just an estimated distance from the runway end.

Note: On 12/07/2007 the FAA issued Order 8260.54A United States Standard For Area Navigation (RNAV). This order is TERPS® Change 20. Guidance by the FAA for implementation of this order is

  1. For new approach procedures
  2. Procedure amendments
  3. Other procedures as time permits and
  4. All US Army procedures within 2 years.

The procedures you created using TERPS® are automatically converted to the new trapezoids. The old criteria was more restrictive and this change opens more airspace to the public. The LNAV, ILS and LOC procedure is included in this release of TERPS®. Other procedures will follow. TERPS® includes a new filter for displaying obstacles. You determine the AGL Height and obstacles with this height or greater will be displayed. Use”0″ to show all.

INSTALLING Airspace®:
