NAOPM (VOR & WEATHER RADAR - Finals) Flashcards
What is the frequency band of VOR
108 - 117.95 Mhz
VOR is subjected to what restriction
Line-of-sight
Where is VOR pointed to
Magnetic North
The VOR produces ___ degree radials at ___ degree spacing which are aligned at the ___ ___ at the VOR location
- 360
- 1
- Magnetic North
These two equipments share the same frequency range from 108 to 117.95
- VOR equipment
- Instrument landing equipment
Frequencies with ODD first digits after the decimal point are allocated to
instrument landing equipment
Two signals being transmitted by VOR
- Variable signal
- Reference signal
This type of VOR signal corresponds to the rotating beam and is a directional signal
Variable signal
This type of VOR signal corresponds to the green light ad is a omni signal
Reference signal
VOR calculates the difference between
- Position of the aircraft
- VOR station
Must be checked before it is used for navigation
IDENT (3 letter morse identifier)
The morse identifier (IDENT) is transmitted how many times
7 times
Types of VOR
