When installing a DME antenna, it should be aligned with the

  1. tail of the airplane

  2. wings of the airplane

  3. centerline on the airplane

  4. nose of the airplane

The correct answer is: centerline on the airplane

Proper installation of a DME antenna requires alignment with the centerline of the airplane. This is because the DME (Distance Measuring Equipment) measures the distance between the aircraft and a ground station, which is located on the centerline of the runway. Placing the antenna in any other position, such as on the tail or wings, could result in inaccurate distance readings. Additionally, the nose of the aircraft can also affect the accuracy of the DME readings due to potential blockage or interference from other equipment located on the nose. Therefore, it is essential to align the antenna with the centerline for proper functioning of the DME.
