Instrument Rating Aeroplane (INRAT) Practice Exam 2025 – Complete Prep Guide

The notion of dipping slightly below Decision Altitude (DA) is grounded in the understanding of instrument approaches and the associated regulations. When a pilot descends below DA, they must be able to visually confirm the required visual references for landing. If visual conditions are established prior to reaching DA, it becomes permissible to descend below this altitude safely.

This practice aligns with the principle that the pilot must have the ability to continue the approach and landing based on visual references that indicate they are coming into a clear landing scenario. If visual references are confirmed, the pilot is effectively transitioning from instrument-based flight to visual flight rules (VFR) conditions.

Maintaining the necessary visual references is essential to ensure safety and to meet regulatory requirements. If a pilot does not have visual contact with the landing environment when reaching DA, they must execute a missed approach to ensure safety.

In this context, the other responses highlight important safety considerations but do not accurately reflect the specific scenario under discussion. The understanding of this regulation ensures that pilots operate safely while still adhering to legal requirements during an approach to land.
