Air Navigation and Air Services Flashcards
State the frequency ban in which NDB operates
the frequency range 200-400 kHz
Define Pilotage
it is the science of determining the position of a ship, aircraft or guided missile and charting a course for the craft safely and expeditiously from one point to another
State how station passage is indicated in the cockpit when using an ADF
When aircraft pass over station the needle points from 12 o’clock to 6 o’clock
state how station passage is indicated in the cockpit when using a VOR receiver
CDI (course direction indicator)
Points to position of VOR
state how many usable radials exist for any given VOR
there are 360 spokes or courses
State three uses for a VOR
- en-route navigation
- Holding fix
- approach aid
State two advantages of a VOR over a NDB
- Easier to use
2. Very accurate method of navigation
List the electronic components of an ILS
- Localizer
- Glide path
- NDB/DME
- Marker beacons
State the most common type of area navigation in use today
GNSS (global navigation satellite system)
State the standard weather limits for a category 1 ILS
200 feet ceiling and 1/2 mile visibility or 2600 RVR
State 3 uses for an NDB
- En-route navigation
- Acting as a holding facility
- Determine an intersection by providing a cross bearing
Used in VFR flying at low altitudes
VNC (VFR navigation chart)
Covers large areas used for initial flight planning and getting big picture (VFR flight)
WAC (world aeronautical chart)
Large scale chart used by VFR pilots in busy terminal airspace
VTA (VFR terminal airspace)
Used for IFR flight below FL 180
