Chapter 6 cross country flight planning Flashcards
3 common ways to navigate
A. Pilotage ( reference of landmarks)
B. Dead Reckoning ( computing direction and distance from a known position)
C. Radio Navigation ( by use of radio aids)
Charts available for VFR nagivation
A. Sectional Charts
B. VFR terminal Area Charts
C. VFR flyway planning Charts
Isogonic line
Broken magenta lines, connect equal magnetic variation. Show amount and direction of magnetic variation
Magnetic variation
Variation is the angle between true north and magnetic north. Expressed as east variation or west variation depending upon whether magnetic North (MN) is to the east or west of the true north
Convert true direction to a magnetic direction
East is least (subtract)
West is Best (add)
Latitude
Run parallel to the equator (east and west)
Longitude
Un perpendicular to the equator (north and south)
Magnetic deviation
The electrical components fucking up the magnetic compass
Types of navigational aids
A. VOR
B. VORTAC
C. DME
D. RNAV
VOR or VORTAC
VHF radio stations that project radials in all directions (360) from the station. Each radials denoted by its outbound magnetic direction. Almost all VOR will be VORTACs- provides standard bearing infor of a VOR plus distance infor to pilots of airplanes which have distance measuring equipments
What frequency range do VORs operate
VHF band between 108 and 117.95 MHz. immediately below aviation communication frequencies
What is VOR radial
Line of magnetic bearing extending from an omnidirectional range (VOR). Projects 380 radials from the station. Also identified ‘from’ the station. 360 will always be located north of the station
VOR NAVAIDS classified
Terminal, low, high
Limitations to VOR reception distances
VORS are subject to line-of-sight restrictions and the range varies proportionally to the alt of the receiving equipment
Different methods for checking the accuracy of VOR receiver equipment j
A. VOT check - plus or minus 4 degree B. Ground checkpoint - C. Airborne checkpoint D. Dual VOR check E. Selected radial over a know ground point
DME
Distance measuring equipment (airborne and ground) used to measure, in NM, slant range distance of an aircraft from the DME navigational aid. Aircraft equiped with it are provided with distance and ground speed info when receiving VORTAC
GPS
Global Positioning System is a satellite radio based navigation system that broadcast a signal used by receivers to determine a precise position anywhere in the world. Receiver tracks multiple satellites and determines a pseudo-range measurements that is then used to determine the users location
3 functional elements of GPS
Space element - consists of 30 satellites
Control element - consists of a network of ground based GPS monitoring and control stations that ensure the accuracy of satellite positions and their clocks
User element - consists of antennas and receiver - processors onboard aircraft that provide positioning, velocity, and precise timing to the user
Different types of GPS receiver available for use
GPS receivers used fro VFR naviagtion vary from fully integrated IFR/VFR installations used to support VFR operations to handheld devices
Purpose of RAIM
Receiver autonomous integrity monitoring (RAIM) is self monitoring function performed by a GPS receiver to ensure that adequate GPS signals are being received from the satellites at all times. GPS will alert pilot if there is no integrity of the GPS
Where can pilot obtain RAIM availability info
Using manufacturer supplied RAIM prediction tool or SAPT on FAA website
If RAIM capability is lost in flight, can you continue using GPS for nav
Without RAIM have no reassurance of accuracy
Preflight checks for GPS equipment
A. Verify that GPS equipment is properly installed and certified fro the planned operation
B. Verify that the databases (nav, terrain, obstacles) have not expired
C. Review GPS NOTAM/RAIM info related to the planned route of flight
D. Review operational status of ground - based NAVIADS and related equipment , appropriate to route of flight
E. Determine that GPS receiver operation manual or plane flight manual supplement is onboard and available for use
Determine what type of operation a GPS receiver is approved for
Reference POH/AFM and supplements to determine limitations and operating procedures for the particular GPS equipment installed
FSS briefer provide GPS notams
No must request GPS/WAAS NOTAMS
WAAS
Wide area augmentation System is a ground and satellite intregrated navigational error correction system that provides accuracy enhancements to signals received from the Global Positioning System. Provides extremely accurate lateral and vertical naviagtion signals to aircraft equiped
Limitations of GPS
A. RAIM capability - many VFR receivers and all hand - held units have no RAIM alerting capability
B. Database currency - must always update for IFR requirements
C. Antenna Location - location matter of convenience that’s performance.
VFR waypoint
Provide pilots with supplementary tool to assist with position awareness while navigation visually in aircraft equipped with area navigation receivers. Provide navigational aids for pilots unfamiliar with an area. 5 letter identifier beginning with VP and retrievable from navigation databases, only used when operating under VFR
After takeoff, attempt to activate VFR flight plan but are unable to contact FSS. What will happen to flight plan
Be held by FSS until 1 hour after the proposed departure time and then is cancelled
If disoriented or lost on cross country flight
- straighten up and fly right. Fly a specific heading in a direction you believe to correct read book page 6-15
Low on fuel; weather deteriorating; inadequate experience; darkness imminent; and/or equipment malfunctioning
GET ON THE GROUND
If cannot locate position
4 c’s
- Climb - higher alt allows better communication capability as well as better visual range for identification of landmarks
- Communicate - use the system. Use 121.5 MHz
- Confess- once communications are established, let them know the problem
- Comply - follow instructions
Most common type of communication radio equipment, and how Many channels are available
Most common type is VHF, operates on frequencies between 118.0 and 136.97 MHz and is classified as 720 or 760 depending on number of channels it can accommodate. 720 and 760 uses .025 spacing with 720 having frequency range up to 135.975 and the 760 going up to 136.975
Universal VHF ‘emergency’
121.5 MHz. This frequency guarded by military towers, most civil towers, FSS and radar facilities
Frequencies used for ground control
121.6 to 121.9 MHz
CTAF
Common Traffic Advisory Frequency, designated for purpose of carrying out airport advisory practices while operating to or from an airport without an operating control tower. May be UNICOM, MULTICOM, FSS or TOWER frequency
UNICOM
Nongovernmental communication facility which provide airport info at certain airports. Use 122.7, 122.725,, 122,8, 122,975, 123.0, 123.05 and 123.075. And with control tower FSS 122.950
ATIS
Automatic terminal info service, continous broadcast of recorded no control info in selected high activity terminal areas. Improve controller effectiveness and relieve frequency congestion by automating the competitive transmission of essential but routine info
Airport without control tower of FSS or UNICOM
Where there is no tower, use multicom frequency 122.9 for self announce procedures. MULTICOM is mobile service not open to public use
RCO
Remote communication outlet, in unmanned communications facility remotely controlled by ATC personnel, provides ground to ground communications between ATC and pilots at satellite airports. IFR cancellation or departure/landing times, departure authorization. Used for advisory whenever plane is below coverage of primary air/ground frequency
How to determine what frequency is appropriate for activating his/her VFR flight plan once airborne
A. Ask FSS briefer during preflight weather briefing
B. Consult communication section under flight service for airport of departure in chart supplement
Heavy - lined box surrounding NAVAID frequency
Indicates FSS frequencies 121.5, 122.2, 243, 255.4 are available and if frequency is on top of the box meaning they are addition to FSS
Thin lined blue box surrounding NAVAID frequency
Without frequencies on top indicates that there are no standard FSS frequencies available. ‘No voice’ symbol
Why would frequency be on top of thin lined blue box
Best frequencies to use in the immediate vicinity of NAVAID site, and ensure reception by the controlling FSS at low alts without terrain interference. Followed by R indicating FSS only receives on that frequency. Pilot will listen for response over NAVAID
