VOR operates on the principle of
Phase differential
Common error to both ADF/NDB and VOR Nav systems is
Terrain effect
VOR radials are calibrated for the mag variation that exists
At the station installation
Error/limitation associated with VOR system is
Site error
Aircraft bonding refers to
Ensuring an even electrical potential between different parts on the airframe
Error/limitation commonly associated with the vor system is
Site error
Aircraft bonding refers to
Ensuring an even electrical potential between diff parts on the airframe
At ranges greater than LOS, the type of radio wave propagation on which ADF/NDB system relies to provide accurate info is
The ground wave
Bending and scalloping used to describe errors in the VOR
When you select a DME freq you are
Selecting a pulsed paired frequency
The adf sense antenna
Resolves the 180 degree ambiguity
Advantage of secondary radar system over primary is that return signal
May contain coded information
Advantage of secondary radar system over primary is that the return signal
Eliminates unwanted returns (clutter)
At ranges up to LOS the type of radio wave propagation on which a/n system relies to provide accurate info is
The direct wave
Error commonly associated with NDB system is
Terrain effect
Aircraft navigated solely by reference to radio navigation aids, max permissible time interval between pos radio fixes is
2 hrs
Ac operating under ifr exempt from req to obtain fixes at specified intervals when
Carrying full time licensed flight navigator or approved self contained Nav system
The adf loop antenna
Identifies the null position
Hf radio waves primarily propagate by
Single and multi-hop sky waves
The centreline of the loc of an ils is determined by
A locus of points of equal signal modulation radiated from each side of the centreline
ILS full deflection of GP needle occurs when
Ac is 0.7 deg above or below GP
Wavelength of a radio signal is defined as
Length of a radio wave from any point to the same point on the next cycle
Microwave landing system MLS has the advantage of
Curved approaches
