VOR Flashcards
Where should the bearing pointer be located relative to the wing tip reference to maintain the 16 DME range in a right hand arc with a right crosswind component?
Ahead of the right wing top
What angular deviation from a VOR course centerline is represented by a 1/2 scale deflection of the CDI?
5 degrees
Full needle deflection of the CDI from the center position to either side of the dial indicates the aircraft is 10 degrees or more off course. A 1/2 scale deflection of the CDI represents 5 deg.
A 2 dot deflection on a 5 dot indicator is 4 degrees
1 dot is 2 degree deflection
A sign that a VOR is undergoing maintenance is
the ID morse code feature is turned off
When a RMI illustration indicates the aircraft is on a specific radial of a station and heading away from the sitation
The tail is pointing to the radial
For IFR operations off of established airways below 18,000 feet, VOR navigational aids used to describe the ‘route of flight’ should be no more than
80NM apart
For IFR operations off of established airways below 18,000 feet, use VORs not more than 80NM apart.
H-VORs are usable up to 200NM apart from 14,500’ to 17,999’
After passing a VORTAC, the CDI shows 1/2 scale deflection to the right. What is indicated if the deflection remains constant for a period of time?
The airplane is flying away from the radial.
CDI deflection is anglar. A constant angle after passing the VOR would indicate that the aircraft is moving furthur form the selected radial.
An aircraft which is located 30 miles form a VOR station and shows a 1/2 scale deflection on the CDI would be how far from the selected course centerline?
2 1/2 miles
There are 5 dots on each side of the center of the CDI. Each dot represents about 200’ per mile 30x200 = 6,000’ or about one mile. A 2.5 dot deflection of the CDI indicates the aircraft is off course about 2.5 miles.
For IFR operations off of established airways below 18,000’, VOR nav aids used to describe ‘route of flight’ should be no more than
80NM apart
H-VORs are usable up to 200 NM apart from 14,500 to 17,999’
Full scale deflection of a CDI occures when the course deviation bar or needle deflects from?
the center of the scale to either far side of the scale
Full scale deflection of the CDI from the center position to either side of the dial indicates the aircraft is 10* or more off course and the exact location is no longer known.
A VOR receiver with normal five-dot course sensitivity shows a three-dot deflection at 30NM from the station. The aircraft would be displaced approximately how far from the course centerline?
3NM
Each dot represents about 200’ per mile. 30 x 200 = 6,000’ or about one mile. A 3 dot deflection of the CDI indicates the aircraft is off course about 3 miles.
Where should the bearing pointer be located relative to the wing-tip reference to maintain the 16 DME range in a right hand arc with a right crosswind component
Ahead of the right wing-tip reference for VOR 2
With a right crosswind on a right hand arc, the aircraft must be crabbed into the wind, toward the station on the right, to maintain the arc. When turned toward the station, the bearing pointer will be in front of the right wing.
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 betwen
10* and 12*
The VOR sensitivity may be checked by noting the number of degrees of change as you rotate the OBS to mvoe the CDI from center to the last dot on either side. The selected course should not exceed 10* or 12* either side.
For operations off established airways at 17,000 feet MSL, in the contiguous U.S. (H) Class VORTAC facilities used to define a driect route of flight should be no farther apart than
200 NM
The standard high altitude service volume between 14,500’ and 18,000’ feet is 100NM
Between two “H” VORTACs the useful range is 200 NM
100NM is a distracter in the service volume of a single “H” VORTAC at 17,000 feet.
