Final answer:
The only north-seeking instrument in a training airplane is the magnetic compass.
Step-by-step explanation:
The only north-seeking instrument in a training airplane is the magnetic compass.
The magnetic compass is a navigational instrument that uses Earth's magnetic field to determine direction. It consists of a magnetized needle that aligns itself with Earth's magnetic field, with one end pointing towards the magnetic North Pole.
This instrument is essential for pilot training because it allows pilots to maintain a consistent heading and navigate accurately, especially in situations where other navigation systems may be unavailable or unreliable.
