What is represented by the mnemonic TURN PALE in aircraft certification categories?

The mnemonic TURN PALE is specifically designed to help remember the various categories of aircraft certification established by the Federal Aviation Administration (FAA). Each word in the mnemonic stands for a different type of aircraft category:

• Transport refers to large aircraft designed to carry more passengers or cargo.
• Utility denotes aircraft that can perform a wider range of operations than normal category aircraft, including aerobatics, but with limitations.

• Restricted applies to aircraft that are only allowed for specific operations and may have limitations due to their intended usage.
• Normal includes most small civil airplanes that are used for general aviation purposes.
• Provisional is associated with aircraft that have been issued special temporary operating authority.
• Acrobatic refers to aircraft specifically certified for aerobatics.
• Limited is designated for aircraft that have specific operating limitations due to factors like their design or configuration.
• Experimental includes aircraft that are not yet fully certified or have not completed the certification process for unrestricted use.

The inclusion of all these categories in the mnemonic accurately reflects the comprehensive classification system used by the FAA, making option D the correct choice.
