6.4.6(q) Define relative bearing using the clock method.

6.4.6(q)  Relative bearing using the clock method.

A relative bearing is a bearing relative to the nose of the aircraft.

We use the clock-code method to identify aircraft and other features quickly and point them out

Nose = 360° = 12o’clock , 

Right wing = 090° = 3 o’clock 

Tail = 180° = 6 o’clock etc..

6.14.2(s) Define Estimated Time of Arrival (ETA);

6.14.2(s)  Estimated Time of Arrival (ETA);

Estimated Time of Arrival (ETA) is the time at which the aircraft is due to arrive at its destination or particular point. 

6.4.6(p) Define relative bearing;

6.4.6(p)  Relative bearing;

A relative bearing is a bearing relative to the nose of the aircraft.

Nose =360° , left wing =90°  Tail =180° etc..

6.14.2(r) Define Estimated Elapsed Time (EET);

6.14.2(r)  Estimated Elapsed Time (EET);

Estimated Elapsed Time (EET) is the time from take-off to arrive over or land at the designated point.

6.4.6(o) Define compass bearing;

6.4.6(o)  Compass bearing;

Compass bearing is the direction to an object from a point; expressed as a horizontal angle measured clockwise from magnetic North, with deviation taken into account. 

6.14.2(q) Define Actual Time of Departure (ATD);

6.14.2(q)  Actual Time of Departure (ATD);

ATD stands for Actual Time of Departure; which is time the aircraft departs its origin. 

6.4.6(n) Define magnetic bearing;

6.4.6(n)  Magnetic bearing;

Magnetic bearing is the direction to an object from a point; expressed as a horizontal angle measured clockwise from magnetic North

6.14.2(p) Define Estimated Time of Departure (ETD);

6.14.2(p)  Estimated Time of Departure (ETD);

ETD stands for the estimated time of departure; which is the planned time of departure for the flight.

6.4.6(m)  True bearing;

True bearing is the direction to an object from a point; expressed as a horizontal angle measured clockwise from true North. Same applies to Magnetic and Compass just from their Norths.

Example 1.

there is a Magnetic Variation of 20’E and Compass deviation of 3’E

True Bearing to the little house is 090’T (True)

Magnetic Bearing to the little house is 070’M (Magnetic) 

eg: 090’T (True) less variation of 20’E = 070’M

Compass Bearing to the little house is 067’C (Compass)

eg: 070’M (Magnetic) less deviation of 3’E = 067’C
