IFR Navigation Flashcards
Types
SPACE based or GROUND based types:
IFR nav Space-based nav GPS-based nav Ground-based nav VOR Nav Navigation procedures
RMI points to the Nav Aid, and tells you your heading!
NOTAMS for ground aids: pilots should disregard nav indications if NAVAID was identified by a NOTAM. Reference a chart
GPS
GPS composed of three major segments:
- Space segment
- Control segment
- User segment
Minimum of 4 satellites for use
DOD responsible for operating GPS satellites
GPS NOTAMS are separate than regular NOTAMS. CHECK DATABASE CURRENCY. (internet, flight service also shows GPS notams
(B06)/U - no GPS
(B06)/G - GPS
VOR (ground based)
VHR (Very high frequency)
Accuracy is generally -1/+1 degree
Chart symbol is a hexagon with 3 black rectangular outjuts
- Line of Sight
- Most are equipped for voice transmission
- Identified by its Morse Code ID
- Radials (emitting 360 “radials” outward… 360,90,180,270 radial and etc.) - **tail of the pinter on the RMI points to the “Radial”
Standard Service Volume (reception range - look up)
- (T) terminal VOR (25NM)
- (L) low alt. VOR
- (HA) high alt. VOR
- (U) unknown
Army aircraft required to test avionics before each flight
(VOR test facility)
(Certified checkpoints at airport [+/- 4 degrees max])
(Certified airborne checkpoints [+/- 6 degrees]) page 3-207
Two independent systems (both arrows)
- Garmin (NAV1)
- KX-165 (NAV2)
More ground based
Bearings:
- emits same signal in all directions
- atmospheric conditions may interfere with signal
- not line of sight
NDB is the ADF
OROCA
Light brown number on chart, is the altitude to climb to if all hell breaks loose, you lose comm, cant find your way, etc. provides clearance of obstacles and traffic
(R)
On map, means that the airport has radio capability or you are in a radio enviornment
(E)
Means that the radios are MONITORED
Change over from home VOR to destination VOR when?
At the half-way point along the route!
