Steps to see where you are in relation to VOR
1. Whats is your aircraft heading 2. The arrow always point to the VOR 3. TO or FROM indication
When checking a dual VOR system by use of a VOT, which illustration indicates the VOR's are satisfactory?
A VOT transmits a 360° radial in all directions. Thus, THE TAIL of each indicator should point to 360°, ±4°.
When using VOR for navigation, which of the following should be considered as STATION PASSAGE? A.The first positive, complete reversal of the TO-FROM indicator. indicator. B.The first movement of the CDI as the airplane enters the zone of confusion. C.The moment the TO-FROM indicator becomes blank.
Answer (A) is correct. When approaching a VOR, the TO-FROM indicator and the CDI flicker as the airplane flies into the zone of confusion (no signal area). Station passage is shown by complete reversal of the TO-FROM
When may VFR waypoints be used in IFR flight plans? A.When the waypoints consist of 5 letter identifiers. B.VFR waypoints may not be used on IFR flight plans. C.When GPS is used as the primary source of navigation.
Answer (B) is correct. VFR waypoints are designed to ease radio congestion in populated areas for VFR traffic only. VFR waypoints are charted on terminal area and sectional aeronautical charts.
What are the primary benefits of satellite based area navigation (RNAV)? A.Standard Terminal Arrival Routes and Departure Procedures are not required. B.Provides optimal routing and altitudes. C.Radio tuning and controller communication is minimized.
Answer (B) is correct. The primary benefits of satellite based area navigation (RNAV) are that it permits aircraft to fly optimum routes and altitudes, thereby increasing the efficiency of the entire National Airspace System.
When checking the sensitivity of a VOR receiver, the number of degrees in course change as the OBS is rotated to move the CDI from center to the last dot on either side should be between A.5° and 6°. B.8° and 10°. C.10° and 12°.
Answer (C) is correct. In addition to VOR receiver checks, course sensitivity may be checked by noting the number of degrees of change in the course selected as you rotate the OBS to move the CDI from center to the last dot on either side. This range should be between 10° and 12°.
To ensure situational awareness while using an autopilot system A.it is important to ensure that all navigational databases are current. B.pilots must verify that the aircraft is tracking the intended flight profile. C.current navigational charts are required.
B.pilots must verify that the aircraft is tracking the intended flight profile.
