|
Definition:
Navigation soley by the reference to visual landmarks. |
|
Method: - Flying to pre-selected checkpoints |
|
- High enough to be clear of obstacles
but low enough to see landmarks |
|
- Take large checkpoints like roads,
bridges and airports. |
|
Advantages:
- Easy to perform |
|
- Doesn’t require special instrument |
|
Disadvantage: - Difficult with few landmarks |
|
- In case of bad visibility it
might be hard to see
landmarks |
|
|
|
|
Definition:
Navigation by predicting the movement of the helicopter
along a planned
route. It is based on the computation of time, speed, distance and direction. |
|
Method:
- Use your E6B to calculate * True Heading |
|
* Magnetic Heading |
|
* Compass Heading |
|
* Flight time and Fuel |
|
- Fly the plotted course on the chart |
|
- Determine your course, altitude, wind direction-speed and true airspeed |
|
Remarks:
It is a combination between Pilotage and Radio Navigation |
|
|
|
|
Definition: Navigation by the use of
instruments in the aircraft and radio facilities on the ground. |
|
|
|
VOR: VHF Omni directional Range |
|
DME: Distance Measuring Equipment |
|
NDB/ADF: Non Directional Beacon/Automatic
Direction Finder |
|
GPS: Global Positioning System |
|
|
|
Navigation Instruments show direction distance
to and from a destination. |
