What is NOT considered a part of the standard equipment on aircraft?

Standard equipment on aircraft typically includes instruments and systems that are essential for navigation, communication, and safety during flight. VHF RTF (Very High Frequency Radio Telephone), ILS (Instrument Landing System), and VOR (VHF Omnidirectional Range) are all critical for navigation and communication, ensuring that pilots can maintain contact with air traffic control and navigate accurately.

In contrast, parachutes are not considered standard equipment for typical commercial or general aviation aircraft. While some specialized aircraft, such as those used for skydiving or certain military aircraft, may carry parachutes, they are not part of the essential equipment required for the safe operation of most aircraft. Therefore, parachutes stand out as the option that does not belong in the category of standard flight equipment, which is why this choice is correct.
