What must be displayed on an approach plate regarding instruments?

The requirement for standard instruments to be displayed on an approach plate is critical because it ensures that pilots have the necessary tools and equipment to safely conduct an instrument approach. An approach plate outlines specific procedures for aircraft to follow when landing at an airport under instrument flight rules (IFR). Included within this information is the list of standard instruments that a pilot must have in the aircraft to complete the approach safely.

These standard instruments typically include devices like an altimeter, attitude indicator, and navigational systems (such as GPS and VOR receivers) to navigate and adhere to the published approach procedures. This is crucial for maintaining situational awareness, especially when visibility is low or other adverse weather conditions exist. The emphasis on standard instrumentation helps to ensure consistency and safety in the operations of all aircraft performing approaches at an airport, regardless of the pilot's experience level.

By adhering to the requirements set forth in the approach plates, the integrity of the instrument approach is upheld, maximizing safety for both the pilot and passengers. Other considerations, while important, do not specifically pertain to the operational standards required for safely conducting an instrument approach.
