vors

Question 1

what does VOR stand for

Answer 1

Very high frequency Omnidirectional Range

Question 2

what frequencies does the vor use

Answer 2

108 - 117.95 MHz

*except 108.1 - 111.95 for localizers

Question 3

what does full scale deflection on a vor

Answer 3

10° (each dot represents 2° of deflection)

Question 4

what about standard service volumes

Answer 4

standard service volumes do not apply to published routes

Question 5

what is the VOR MON

Answer 5

VOR Minimum Operational Network

ensures as old VORs are decommissioned, a MON airport (i.e. equipped with a VOR approach) is available within 100NM regardless of airacrft position in the CONUS

Question 6

draw the vor service volumes

Question 7

how often should a vor receiver check occur

Answer 7

30 days

Question 8

what are the types of vor checks

Answer 8

±4: VOT (VOR ground test facility), repair station, ground checkpoint, & dual vor cross check

±6: airborne check & above a prominent ground landmark within 20 NM of the VOR at a reasonably low altitude

Question 9

what is a vot check sign off

Answer 9

Date
Error (bearing error)
Place
Signature

Question 10

what are VOR limitations

Answer 10

cone of confusion: as you get closer the needle starts to deflect and the flag flips when up you pass over the VOR

reverse sensing: if used incorrectly. the radial will say it’s on you left when it’s actually on your right

requires line of sight: VOR doesn’t work through mnts

Question 11

does MGA get reverse sensing

Answer 11

ONLY if AHRS IS PULLED
