C-FXII C172K Performance Data

Airspeed indicator has mph on the outside, KIAS on the inside.

All speeds in Sections I and II are mph indicated, others are calibrated mph, unless otherwise stated.

Use the conversion table to convert calibrated to indicated.

Using mph is recommended, as it's easier to read off the dial. KIAS are included here for comparison with other aircraft you may fly.

Understand how to find all this data in the aircraft documents. You can be asked to find them on the flight test, and you will probably someday have to find them for another aircraft in an unfamiliar POH.

Bold speeds you must have memorized for the exam.
