Question

(11-2E-8V3)

When operating in RNP 10 or BRNAV airspace, ____ must be used as the primary navigation solution. The ____ solution cannot be used longer than ____ from the time ____. Refer to RNP 10/BRNAV update and contingency procedures in this volume.

Answer 1

In RNP 10 or BRNAV airspace, the primary navigation solution is RNAV. The INS solution cannot be used longer than 10 minutes.

Step-by-step explanation:

In RNP 10 or BRNAV airspace, the primary navigation solution that must be used is the area navigation (RNAV) solution. The inertial navigation system (INS) solution cannot be used longer than 10 minutes from the time of the GPS failure.

RNP (Required Navigation Performance) and BRNAV (Basic Area Navigation) are navigation specifications that ensure aircraft can navigate accurately along specific routes. RNAV is a type of navigation system that allows an aircraft to fly a desired flight path without relying on ground-based navigation aids.

An RNP of 10 means that a navigation system must be able to calculate its position to within a circle with a radius of 10 Nautical Miles (NM). Similarly, an RNP of 0.3 means the aircraft naviga- tion system must be able to calculate its position to within a circle with a radius of 3 tenths of a NM.
