Lesson 11/15 Flashcards
What is a flight computer?
A device that aids pilots in solving a variety of calculations important for flight planning and navigation.
What are the two sides of the E6B flight computer?
- Calculator side
- Wind side
What types of problems does the Calculator Side solve?
- Time-speed-distance problems
- Fuel consumption
- Various conversions
What does the Wind Side of the E6B flight computer calculate?
- Wind correction angles
- Ground speed
What are the three scales on the Calculator Side of the E6B?
- Outer (stationary) scale
- Middle scale
- Inner (rotating) scale
What is the significance of the number 60 on the middle scale?
It is marked differently than other numbers and is the unit index for the time scale.
How does the E6B assist with time calculations?
It allows reading minutes on the B scale or hours plus minutes on the C scale.
What does the box around the 10 on each scale indicate?
It is the 10 index or unit index used for conventional multiplication and division problems.
What does the inner scale of the E6B represent?
It can be used to represent time, with ticks indicating either 5 minutes or 10 minutes.
What is drift in aviation?
The error caused by wind pushing the aircraft off course.
What is the wind correction angle (WCA)?
The difference between the aircraft’s heading and its course due to wind.
What components are included in the wind triangle?
- True Course/Ground Speed
- Wind Speed/Wind Direction
- True Heading/True Airspeed
What does Ground Speed refer to?
How fast the helicopter is moving on the ground.
What is Calibrated Air Speed (CAS)?
Indicated Airspeed corrected for instrument and position error.
What is True Air Speed (TAS)?
KCAS corrected for non-standard temperature and pressure.
What is True Heading?
True Course corrected for Wind Correction Angle.
What is Magnetic Heading?
True Heading corrected for magnetic variation.
What is Course Heading?
Magnetic Heading corrected for compass deviation.
What is the purpose of the E6B flight computer tutorial?
To explain the operation and markings of the E6B flight computer.
Fill in the blank: The E6B flight computer is used for _______ computations.
[navigational]
True or False: The wind triangle helps determine the effect of wind on flight.
True
What materials are used in the lesson on flight computers?
E6B
What is the completion standard for the lesson?
The student must display an understanding of the material presented through oral examination.
