Departure Roll

A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

Flight narrative

The flight began with a departure roll from runway 27 at KGNB Granby Grand County Airport, a Cessna Skyhawk taking to the skies. The aircraft required a takeoff distance of 829 meters, which was 55% of the runway length. The liftoff speed was 58 knots, and the local weather conditions were favorable, with a temperature of 16 degrees Celsius and a gentle wind of 1 knot at 270 degrees.

As the aircraft gained altitude, it entered a level cruise, starting 3 miles west of Granby and lasting for 7 minutes. During this time, the aircraft covered a distance of 13 nautical miles. The enroute level cruise was a smooth and efficient segment of the flight, allowing the pilot to maintain a steady altitude and speed.

As the aircraft approached its destination, it began its descent, starting 4 miles east of 20V Mc Elroy Airfield in Kremmling. The descent was a controlled and gradual process, with the aircraft losing 1,215 feet in altitude over a distance of 5 nautical miles in 4 minutes. The pilot expertly guided the aircraft through this critical phase of flight, ensuring a safe and smooth transition to the final approach.

The final approach to runway 09 at 20V Mc Elroy Airfield was a precise and controlled maneuver, with the aircraft approaching from the west at a heading of 103.0 degrees. The aircraft was at an altitude of 147 feet above ground level (agl) and 0 nautical miles from the runway threshold.

The landing itself was a textbook example of a well-executed maneuver. The aircraft touched down on the runway at a speed of 47 knots, with a touchdown distance of 324 meters. The touchdown rate was smooth, at -123 feet per minute, and the runway touchdown alignment was perfect. The local weather conditions were similar to those at departure, with a temperature of 15 degrees Celsius and a gentle wind of 1 knot at 270 degrees.

Following the landing, the aircraft taxied to the parking area, taking just 1 minute to cover a distance of less than 1 nautical mile. The total flight distance was 23 nautical miles, and the flight used a total of -15 kilograms of fuel. The Cessna Skyhawk performed admirably throughout the flight, demonstrating its reliability and efficiency in a variety of flight conditions.

Landing report
Landing on runway 09 at 20V Mc Elroy Airfield in the Cessna Skyhawk
Landing Score 99.64 %
Landing Summary

The Cessna Skyhawk successfully landed at Mc Elroy Airfield, achieving a score of 99.6%. The aircraft approached the runway from the west, heading 103.0° at an altitude of 147 feet above ground level (agl) and 0 nautical miles (nm) from the runway. The final approach was executed with precision, and the aircraft touched down on runway 09 with a smooth touchdown rate of -123 feet per minute (fpm).

The threshold height was good, indicating that the aircraft was at the correct altitude as it approached the runway. However, the threshold speed was slightly below the target speed of 56 knots (kn), which may have been due to the aircraft's descent rate or the pilot's decision to flare earlier than expected. Despite this, the touchdown distance of 324 meters was good, and the touchdown speed of 47 kn was within acceptable limits.

The local weather conditions were favorable for the landing, with a temperature of 15°C and a wind speed of 1 kn from 270°. This resulted in a negligible crosswind component and a slight tailwind of 1 kn, which may have contributed to the aircraft's slightly below-target threshold speed. The total landing distance of 565 meters was 34% of the runway length, indicating that the aircraft had sufficient runway remaining for a safe stop.

The runway touchdown alignment was perfect, and the rollout alignment was also spot on, demonstrating the pilot's skill and control during the landing. Overall, the Cessna Skyhawk's landing at Mc Elroy Airfield was a success, with the aircraft executing a smooth and controlled touchdown and rollout.
