This document provides an introduction to navigation methods for aircraft, including visual flight rules (VFR), instrument flight rules (IFR), and various types of radio navigation equipment. It focuses on radio navigation methods like non-directional beacons (NDB), VHF omnidirectional range (VOR), distance measuring equipment (DME), and instrument landing system (ILS). Key aspects like tracking VOR courses, ILS localizers and glideslopes, and ILS categories are explained. The goal is to prepare pilots flying Boeing 737-800 aircraft to use radio and area navigation methods.

Introduction to Navigation

7. Area NavigationHowever, as we are going to fly Boeing 737-800, today we shall focus on Radio Navigation and Area Navigation.http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong

9. The main principles:1. Direction - By bearing or radio phrases.2. Distance – By measuring of travel times.
10. The main types of Radio Equipment :1. NDB – Non-directional Beacon 2. VOR – Omni-directional Radio Range 3. DME – Distance measuring equipment 4. ILS – Instrument Landing System http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
14. Needle in ADF (Automatic Direction Finder) will always point to the NDB when tuned to the channel
15. There is only one NDB in Hong Kong Lam Chau (LC 390 kHz)
16. Most NDB has been decommissioned, such asHKG (Cape D’Aguilar) and SL (Sha Lo Wan) http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
17. VOR VHF Omni-Directional Range - VOR stands for VHF Omni-directional Range - On VHF – (118.0 MHz - 117.95 MHz ) - Designed to provide 360 courses for navigation - In modern days, there are usually two different VORs : 1. VORDME (VOR + Distance Measuring Equipment) 2. VORTAC (VOR + Tactical Aircraft Control - Military) - Both will provide direction and distance for navigation http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
18. VOR Indicator - We may read and navigate the VOR by using the VOR Indicator - A: The VOR bearing to be intercepted - B: The knob is to rotate the card (A) – turning the course - C: To and from shows whether we are tracking the radio courseFROM or TO the VOR - D: The needle at the middle can swing left or right- Represent the course selected is on the left/right of the aircraft http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong

20. 2. Turn the knob to rotate the course card. (to the course you want to intercept)3. Check the TO/FROM indicator.4. The Course Deviation Indicator will move slowly to the centre5. Turn your aircraft to the course heading6. Keep tracking the course with the Course Deviation Indicator.
22. ILS Instrument Landing System - ILS stands for Instrument Landing System. - It is divided into two system mainly – Localizerand Glideslope - For Horizontal guidance and Vertical guidance respectively. http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
23.
24. Middle Marker or even Inner Maker for some airport - In some airport, there are no Glideslopeand the Localizer can be offset – such as LOC/DME Rwy 16 Approach at Macau Intl http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
25. ILS Glideslope - Glideslope (G/S) – An array for Vertical Guidance - Usually 3 degrees Glide path . - Some are steeper due to restrictions– Kai TakIGS – 3.1degree , London City ILS Rwy10 - 5.5 degrees) http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
26. ILS for landing Tune the navigation frequency to the corresponding ILS frequency(Rwy 07L ILS - 111.1 MHz) Tune the course to runway heading (Rwy 07L CRS 073) Fly on an intercept heading and fly towards the ILS (Usually 30 degrees from course) Engage the Approach Mode on Autopilot The course deviation needle (as in VOR) will move to the centre (that is localizer) The points on the right will come to centre(point above centre is flying lower than the GS, below is that the aircraft is flying higher than GS) Intercept Low, never Intercept High! http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong

28. CAT I, CAT II and CAT III They have different requirements on decision height (Decision on LAND or GO AROUND) and on Visibility or Runway Visual RangeCategory IIIc is capable for full autoland (Good but much expensive due to equipment!) At Hong Kong International Airport, 07R, 07L and 25L are capable forCat II landing, while 25R is capable for Cat II and Cat III landing. http://hk.vatsea.net/(+852) 35947770 VATSIM Hong Kong
