Instrument Rating Checkride Practice Test

Question: 1 / 400

What is the significance of a "decision altitude" (DA)?

It is the altitude for initiating a go-around if conditions are not met

It is the minimum altitude for cruising flight

It is the altitude at which navigation decisions must be made

It is the altitude at which a pilot must decide whether to continue the approach or go around

The concept of "decision altitude" (DA) is critical during instrument approaches. It refers to a specific altitude on an approach that is predetermined as the height at which the pilot must make a crucial decision about whether to continue the landing or execute a go-around. This decision is based on whether the required visual references for landing are clearly in sight. If the aircraft reaches the DA and the pilot does not see these references, the correct procedure is to initiate a go-around to ensure safety.

Understanding this helps pilots maintain situational awareness and make timely decisions during the landing phase of flight. The importance of DA is underscored in instrument flying, where pilots rely heavily on instruments, particularly under poor visibility conditions. The precision of timing at the DA spot is essential for ensuring safety and adherence to standard operating procedures during an approach.
