When lined up for takeoff on RWY 27, the compass and heading indicator should display a heading of about?

When an aircraft is lined up for takeoff on a runway, the indicated heading on both the compass and heading indicator should closely align with the magnetic heading of that runway. Runway 27 indicates it is oriented towards 270° magnetic. However, due to various factors such as magnetic variation and potential misalignment of the heading indicator, there can be slight discrepancies in what is displayed.

The correct answer indicates a heading of about 275°, which is likely accounting for possible deviations or errors in the instruments. It suggests an understanding that while the runway is aligned with 270°, instruments may require calibration or adjustment and might read slightly higher, reflecting local magnetic influences and any deviation from true heading.

In real-world flying, pilots must always be prepared to interpret their instruments, especially when getting lined up for takeoff. Displaying 275° means the instruments are functioning within acceptable limits, showcasing the necessary adjustments pilots must consider as they align with the runway during takeoff procedures.
