Performance Data
This section outlines the performance specifications of the Cessna 172K, including takeoff and landing distances, climb rates, and cruise speeds. For example, the takeoff distance over a 50-foot obstacle is approximately 1,600 feet under standard conditions.
Operating Limitations
The operating limitations section details the maximum weight, center of gravity limits, and airspeed restrictions for the Cessna 172K. The maximum takeoff weight is 2,400 lbs, and the stall speed in landing configuration is 47 knots.
Emergency Procedures
Emergency procedures provide critical steps for pilots to follow in various emergency situations, such as engine failure or electrical malfunctions. For instance, in the event of an engine failure during takeoff, pilots should maintain a safe airspeed and prepare for a controlled landing.
Preflight Inspection
The preflight inspection checklist ensures that pilots conduct a thorough examination of the aircraft before flight. This includes checking fuel levels, oil levels, and the condition of control surfaces.
Weight and Balance
This section explains how to calculate the weight and balance of the aircraft, which is crucial for safe flight operations. It includes charts and formulas to determine the center of gravity based on passenger and cargo distribution.
Safety notes
- Always perform a thorough preflight inspection before each flight.
- Ensure weight and balance calculations are within limits before takeoff.
- In case of engine failure, maintain a safe airspeed and prepare for landing.

Preparation: a. Inflate tires to recommended operating pressures. b. Remove all wing tank drain plugs to remove all fuel. c. Remove oll sump drain plug to drain all oil. d. Move all sliding seats to the most forward position. All seat backs should be in the most nearly vertical position. e. Put flaps in the fully retracted position. f. Place all control surfaces in neutral position. 2. Leveling: a. Place scales under each wheel (500# nose, 1000# each main, minimum capacity for scales). b. Deflate nose tire to center bubble on level (See Diagram). 3. Weighing: a. With the airplane level and brakes released, record the weight shown on each scale. Deduct the tare, if any, from each reading. 4. Measuring: a. Obtain measurement "A" by measuring horizontally (along the airplane center line) from a line stretched between the main wheel centers to a plumb bob dropped from the firewall. b. Obtain measurement "B" by measuring horizontally and parallel to the airplane center line, from center of nose- wheel axle, left side, to a plumb bob dropped from the line between the main wheel centers. Repeat on right side and average the measurements. 5. Completing the Form: a. Using weights from (3) and measurements from (4) the airplane weight and C. G. can be determined. b. Obtain licensed empty weight by adding weight and mo- ment of unusable fuel to airplane empty weight and moment. There are 4 gallons of unusable fuel (Weight = 24 Lbs, Moment = 1104 Lb. In.) in airplane with either the 42 gallon or 52 gallon capacity wing located fuel systems. Level at upper door sill or leveling screws on left side of tailcone.
