How do you calculate the true bearing from a station (QTE)? Assuming that :


You are flying on a compass heading of 141°,
The compass deviation is given as +3°,
The variation read on the chart is 3° East,
The wind correction angle is +10° and
The relative bearing to the airport is 307°


what would the radial from the station be to the true north?

I thought QTE was a standard term. I did not know that American pilots did not know it.

*QTE: True Eminent from station — What is my true bearing from you? QTE = Reciprocal of true bearing to station.

To derive the true bearing I did the following.

I assume that since compass heading is 141° and deviation is +3°


Magnetic heading should be 141-3 = 139°
True heading (would be without the variation given as 3°E) = 139 +3 = 141°
True bearing to station = True heading + relative bearing = 141+307 =  448°
True bearing = 448-360 = 88°
True eminent from station = 268°


However the answer given is 274°. 

I want someone with more aviation knowledge to tell me if I am wrong and if so, where is the "break" in my logic?



Reason for question: Navigation problem with an answer given, however I believe the answer to be wrong - Needed an expert opinion.
You are quite close to the answer, you just made a mistake with the sign of east compass deviation, hence underestimated the true heading by 6°. The actual angles are like this:

  

The compass deviation is given as +3° while it should be given as 3° east, like the variation. It could be misleading.

Exactly as you then developed, the unknown yellow angle is equal to:


True heading + (relative bearing - 180)
147 + (307 - 180) = 147 + 127 = 274°
