Approach Ban (CAR 602.129)
THIS DOES NOT APPLY TO PART 7 AIRCRAFT
- Runway Visual Range: The range over which the pilot of an aircraft on the centre line of the runway can see the surface marking or the lights delineating the runway.
- RVR Symbol: An A or B in a pizza slice
- Approach Ban - If the RVR is less than the minimum RVR (RVR A and/or B), if where A and B are measured:
- The RVR A for the runway of intended approach is less than 1,200 ft to
- RVR B is less than 600ft
- If A is less than 1,200, or B is less than 600, then you cannot approach the runway unless:
- Already past the FAF inbound (if no FAF, the the point of final approach course)
- On a training flight, and you inform ATC that you will do a missed approach
- RVR is varying between distances less and greater than the minimum RVR
- RVR is less than the minimum, AND the ground vis at the aerodrome is reported to be at least 1/4 SM
- CAT III minima
- If RVR is given for a runway, it does not apply for the reciprocal approach
- Non-Precision, APV, CAT 1 and CAT II precision approaches are not permitted when low visibility procedures are in effect
- No RVR, No Ban!

3:35 PM
Non-Directional Beacons (NDB):
General:
·Frequency: 190-415kHz, and 510-535kHz (Low and Medium frequencies)
·Signals follow the curve of the Earth - not line of sight
·Accurate to +/- 5 degrees for approaches, and +/- 10 degrees for enroute
·NDB's Morse code identifier indicates its health - if unheard then it is unacceptable for IFR navigation
·MH + RB = MB (mag heading + relative bearing = magnetic bearing/bearing to station)
·Time to NDB (min) = Seconds ÷ degrees of relative bearing change
Intercepting (ADF):
·Draw a diagram using your bearing to the station and the magnetic heading of the aircraft
Intercepting (RMI):
·Inbound: Desired - Head - Beyond
·Outbound: Tail - Desired - Beyond
Errors:
1.Night Effect: NDB signal bounce off the ionosphere and mess with the ADF; greatest just before sunrise and just after sunset
a.Can be remedied by selecting lower frequencies, flying higher, or selecting a closer NDB
2.Mountain Effect: Signals bounce off of irregular surfaces and mess with the ADF
3.Quadrantal/Banking Error: The aircraft's electromagnetic field messes with the signals coming in to the ADF; significant on approaches
4.Coastal Effect: Waves refract off the coast; greatest within 30 degrees of the coast line
5.Electrical Storms
6.Precipitation Static: Caused by precipitation, can be reduced my slowing down
VHF Omni-Directional Range (VOR):
General:
·Frequency: 112.1 to 117.96 MHz (VHF)
·Limited to line of sight operations
·CDI indicates a deviation of 2 degrees per dot
·Not heading dependent
·Accurate to +/- 3 degrees on published radials
o+/- 4 degrees when checking equipment against another VOR/VOT
o+/- 6 degrees when comparing to a landmark
VHF Direction Finding (VDF):
Requires no special onboard equipment; aerodrome will be able to determine the direction of your transmission and will be able to direct you to track direct the station.
Intercepting:
·FROM top, TO bottom
·FROM must be used when flying away from the station to give correct CDI deflection
·TO must be used when flying inbound to the station to give accurate CDI deflection
Distance Measuring Equipment (DME):
·Frequency: 960 to 1215 MHz (UHF)
·Line of sight - same range calculations as a VOR
·Uses the principles of secondary radar - the airborne equipment interrogates the ground station, and times the response to get a distance
·Measures SLANT RANGE in nm (use Pythagoras to determine horizontal distance)
·Accurate to +/- 0.5nm or +/- 3 percent (whichever greater) from a VOR checkpoint
Instrument Landing System (ILS):
Composed of a Localizer and a Glide Slope Indicator:
·Always preceded by an I identifier
Localizer (Azimuth Guidance):
·Frequency: 108.1 to 111.9 MHz (VHF)
·Signal is 5 degrees wide (2.5 degrees of either side, 0.5 degrees per dot)
oCan range from 3 degrees to 6 degrees wide and is usually 700ft wide at threshold)
·A back course may be available - usually same coverage as front signal
·Aligned with runway by 3 degrees or less (published if otherwise)
·Localizer signal is protected and can be considered reliable unless stated on the chart
·Signal coverage area of the localizer:
Glide Slope Indicator (Vertical Guidance):
·Frequency: 329.3 to 335 MHz (UHF)
·Paired with the Localizer frequency so that it is automatically selected when the localizer is set
·Signal is 1.4 degrees thick (0.7 degrees on either side of centre)
oProvides a 55ft +/- 5ft threshold crossing height
·DOES NOT HAVE A USEABLE BACK COURSE
Global Navigation Satellite System (GNSS):
General:
·The only GNSS approved for use in Canada is GPS
·There are 24 GPS satellites orbiting the earth at 20,200km
·Occupy 6 orbital planes spread apart by 55 degrees
·Accurate within 6m horizontally and 8m vertically
·Requires minimum 4 satellites to solve for latitude, longitude, altitude, and time (GPS fix)
·GPS must be mounted to the aircraft, and backup instrumentation must be available should the GPS get a RAIM alert
Course Deviation Indication:
The CDI needle will show distances from the selected track, but is sensitive relative to the proximity to departure and destination aerodromes
·Enroute Mode: Full deflection is 5nm, 1nm per dot
·Terminal Mode: Full deflection is 1nm, 0.2nm per dot
·Approach Mode: Full deflection is 0.3nm, 0.06nm per dot
Augmentation Systems:
Integrity Monitoring:
The ability for IFR GPS to monitor and alert the pilot of any accuracy degradation of the GPS system
RAIM: Receiver Autonomous Integrity Monitoring
·Requires at least 5 satellites
·RAIM alert will occur if:
oEnroute navigation is off by 2nm
oTerminal navigation is off by 1nm
oNon-precision approaches are off by 0.3nm
oIf a satellite malfunctions
SHOULD ALWAYS CHECK RAIM BEFORE DOING A GNSS APPROACH
FDE: Fault Detection Exclusion
An extension of RAIM; can detect which satellite is malfunctioning and can exclude it form the position calculations, therefore making GPS navigation possible again
·Require 6 satellites
·All WAAS enabled receivers have FDE
Barro-Aiding:
When a GPS receives information from an altimeter; reduces the requires number of satellites by 1
Accuracy Improvement:
Wide Area Augmentation System (WAAS): Satellite based; ground reference stations track and correct for satellite inaccuracies. These are then processed, and disseminated to aircraft via 2 geostationary satellites.
·WAAS GPS is accurate to 2m (compared to 20m)
·WAAS allows for LPV approaches with vertical guidance, and has potential to support CAT 1 approach standards
LAAS (Local Area Augmentation System): Ground based; ground stations at the airport relay information to the aircraft directly
GPS use for IFR Navigation:
·GPS can be used for all stages of IFR flight
·GPS can be used to identify ground stations, even if they are not in operation as long as the GPS database remains current (you can fly unserviceable approaches)
·GPS enabled aircraft can follow airways below the MEA down to the MOCA
·GPS overlay approaches are identified by a small (GNSS) symbol; you can in many cases bypass the procedure turn and fly direct to the FAF
·Classified as an Approach Procedure with Vertical Guidance (APV)
