Navigation Flashcards
A VOR receiver with normal five-dot course sensitivity shows a three-dot deflection at 30 NM from the station. The aircraft would be displaced approximately how far from the course centerline?
3 NM
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
10 and 12 degree
What indication should a pilot receive when a VOR station is undergoing maintenance and may be considered unreliable?
no coded identification, but possible navigation indications
Where does the DME indicator have the greatest error between ground distance to the VORTAC and displayed distance?
high altitudes close to the VORTAC
Which distance is displayed by the DME indicator?
slant range distance in NM
When using VOR for navigation, which of the following should be considered as station passage?
the first positive, complete reversal of the TO FROM indicator
Full scale deflection of a CDI occurs when the course deviation bar or needle
deflects from the center of the scale to either far side of the scale
What is the meaning of a single coded identification received only once approximately every 30 seconds from a VORTAC?
The DME component is operative and the VOR component is inoperative
Which DME indication should you receive when you are directly over a VORTAC site at approximately 6000 feet AGL?
1
An aircraft which is located 30 miles from 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
When a VOR/DME is collected under frequency pairings and the VOR portion is inoperative, the DME identifier will repeat at an interval of
30 second intervals at 1350 Hz
What angular deviation from a VOR course centerline is represented by a full scale deflection of the CDI?
10 degree
When is one time you may use a suitable RNAV system to substitute for a ground-based NAVAID?
when the ground based NAVAID is out or service
Which of the following should be considered as station passage when using VOR?
the first complete reversal of the TO-FROM indicator
A particular VOR station is undergoing routine maintenance. This is evidenced by
removal of the identification feature
