Radio Nav Flashcards
What is the meaning of VOR
Very high frequency omni directional range
What is the frequency allotted for VOR
108 - 117.95 MHZ
VOR stations transmit radio beams on what?
Radials
What are the 3 kinds of VOR stations
Terminal, low and high altitude
You should always identify the VOR before using by checking
Accuracy
What is an advantage of the VHF frequency used for VOR navigation
VHF radio waves are less susceptible to interference
What navigation capability does a VOR/DME provide
Position and distance
Why is it important to set your VOR indicator to agree with your intended course
To avoid reverse sensing
Maximum error for VOR on the ground
4 Degrees
Maximum error for VOR in flight or IFR navigation
6 Degrees
A procedure to find your position in the air using 2 VORs
Cross Checking
What is the ADF frequency range
190-535 KHZ
What is the meaning of ADF
Automatic Direction Finder
NDB meaning
Non-directional beacon
ADF requires two antennas
Directional and sense antenna
What is an ADF called if the nose is fixed at 0 degrees
Fixed card
What heading will bring the aircraft to the NDB station
Magnetic Bearing
The angular difference between the nose and the NDB station
Relative Bearing
A heading based on magnetic compass
Magnetic Heading
Magnetic heading plus relative bearing equals
Magnetic Bearing
A technique in flying using the NDB by keeping the needle of the ADF centered on the aircraft nose is called
Homing
ADF equipment is capable of receiving signals from what type of facility
NDB and AM commercial broadcast station
A horizontal direction from one point to another measured clockwise from the reference point
Bearing
What is true about homing when using ADF during crosswind conditions
Homing to a radio station will result in a curved path
Which is true regarding tracking on a desired bearing when using ADF during crosswind conditions
When on the desired track outbound with proper drift correction, the ADF will deflect to the windward side of the tail position
How should a pilot make VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface
Set OBS on the designated radial. CDI must be centered within plus or minus 4 degrees of the radial with a FROM indication
What navigation capability does VORTAC provide
Course guidance and distance
How many GPS satellites are required to yield a 3D position and time solution
4
Deviation in a magnetic compass is caused by
magnetic fields within the aircraft distorting the lines of magnetic force
the angular difference between true north and magnetic north is
magnetic variation
