What are the Primary and Secondary instruments for DR?
|
Primary:
-BDHI -Clock -Airspeed Indicator Secondary: -Altimeter -Outside Air Temp. Gauge |
|
|
Define True Airspeed and Air Vector
|
True Airspeed: speed of the aircraft through the air mass and is not affected by wind speed or direction. Calibrated Airspeed corrected for density.
Air Vector: the aircraft's direction and speed represented by True Heading and True Airspeed |
|
|
Name the four steps involved in flight planning
|
1) Measure True Courses and distances
2) Use preflight winds to determine appropriate headings and Ground Speeds 3) Using Ground Speed, compute an enroute time for each leg (ETE) 4) Using ETE and a given fuel flow, compute fuel consumption for each leg (leg fuel). |
|
|
Define Drift Angle. It is measured left or right of what?
|
Drift Angle: the difference between true heading and track measured either left or right of true heading.
|
|
