(6) Navigation Flashcards
Successful Air Navigation involves:
- Piloting the aircraft without being lost
- Not breaking any laws
- Not endangering safety of those on board
Difference between air navigation and navigating craft surface:
- A/C travel at higher airspeeds and at high altitudes
- A/C cannot stop mid air
- A/C is safety limited by the amount of fuel it carries
- No in-flight rescue personnel
- Collisions with obstructions are fatal
Factors to consider in selecting the best route:
- Airspace limitation/restriction
- Highest Elevation
- Aircraft endurance
- Rules of Air
- Weather
- Wind Direction
Using the aeronautical charts, pilots are able to determine:
- Position
- Safe altitude
- Best route
- Radio aids to navigation
- Airspace limitation/restriction
7 categories of legend:
1 Airport
2 Airport data
3 Radio aids to navigation
4 Airport traffic services
5 Airspace information
6 Obstruction and Topographic Information
7 Misc Data
Stages of flight planning
1 Preflight planning process (preparation of flight computer, flashlight, nav plotter, nav log, charts, aip, sunglasses)
2 Initial planning (checking NOTAMS and weather data)
3 Layout of the course (Course consideration, Airspace Limitation/Restrictions, Drawing the Course, Checkpoints)
4 Altitude (VFR Cruising Alt., Terrain, Cloudbase, Airspace Limitation/Restriction)
5 Distances
6 Airspeeds that need to be attained
Preparing flight plan indicating phases and route of flight
Route of flight
- Planning the course
- Indicating checkpoints
- Computing time, distance, fuel burned
- Deviating to alternate
- Reporting points
Direction
- Wind correction angle
- Wind triangle
- True Heading
- True Course
- Magnetic Heading
- Compass
- Variation
- Deviation
Facts about latitudes
- known as parallels
- parallel from one another and never meet
- run in east/west direction
- measure distance north/south from equator
- shorter on the poles, longer on the equator
- intersect with prime meridian in right angles
- lie in planes that cross earth’s axis in right angles
Facts about longitudes
- known as meridians
- run in north/south direction
- measure distance east/west from prime meridian
- farthest apart at the equator and meet on poles
- cross the equator in right angles
- equal in length
- halves of great circles
