Energy Management on Short Final
A DA40's slippery airframe, excess approach energy, and the decision to go around — runway excursion risk at Brooksville
The scenario
Departing Brooksville–Tampa Bay Regional Airport (KBKV), Brooksville, FL — Runway 09, inbound for landing after a 1.5-hour cross-country flight. Elevation 76 ft MSL. The runway is 7,001 ft long, plenty of concrete for a normal landing.
It is a clear, calm afternoon: OAT 24°C, winds 080° at 4 kt (nearly calm, slight left crosswind for Runway 09). Visibility 10 SM. KBKV tower is active (part-time, 0700–2200 local). You are in Class D airspace; Class B (Tampa) is above 6,000 MSL. You are at 2,500 ft MSL, 8 nm out, cleared for a straight-in approach to Runway 09.
Aircraft: Diamond DA40, solo, 2,400 lb (within limits). Fuel-injected Lycoming IO-360, constant-speed prop, fixed gear, G1000 glass panel. The DA40 is a slippery, efficient airframe — it floats in ground effect and holds energy well. Energy management on approach is critical.
Pilot: you — a Commercial pilot, 800 hours total, 120 hours in type (DA40). You have 15 landings at KBKV in the past 18 months. You are current and proficient. This is a routine approach.
The approach is stable at 1,500 ft MSL: 70 KIAS (Vref), 500 fpm descent, on glide slope. Flaps are in landing configuration (full down). The constant-speed prop is set for approach (2,000 RPM). You are on speed, on glide path, and the runway is made.

The decision
Before we get into the decision tree — what do you already know about the DA40's approach and landing characteristics? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB GAA19CA582 (2019): A Diamond DA40 on an instructional flight experienced a loss of control during an aborted go-around when the pilot cut power and applied brakes with insufficient runway remaining. The pilot initiated a go-around from short final, then decided to abort it and land. The decision to abort the go-around without adequate runway distance to safely stop the airplane resulted in a loss of control, runway excursion, and impact with a concrete barrier. The probable cause was the pilot's failure to accurately communicate his intentions to ATC and his decision to abort the go-around without sufficient runway remaining.
NTSB ERA21LA039 (2020): A Diamond DA40 on a Part 91 supervised solo instructional flight lost directional control during landing when the aircraft bounced and drifted left. The student pilot's attempt to abort the landing was unsuccessful, and the aircraft struck a taxiway sign and cartwheeled before impacting a security fence. The probable cause was the pilot's loss of directional control while landing, which resulted in a runway excursion.
NTSB GAA19CA038 (2018): A Diamond DA40 flown by a solo student pilot experienced a runway excursion and struck a taxiway sign after landing with excessive speed. The accident was attributed to the student pilot's excessive taxi speed during a turn from the runway to a taxiway. The underlying cause was the student's failure to manage energy on approach and landing, resulting in a high-speed touchdown and loss of directional control during the rollout.
The common thread across all three accidents: the DA40's slippery airframe and efficient design mean it holds energy well. Excess approach energy — whether from high speed, extended flare, or a late go-around decision — consumes runway distance quickly. The pilots in these accidents either (a) aborted a go-around with insufficient runway to stop, (b) lost directional control during a bounced landing, or (c) landed with excessive speed and lost control during rollout. All three are runway-excursion events in a type that does not forgive energy mismanagement.
At KBKV, Runway 09 is 7,001 ft long — plenty of runway for a normal landing. The off-field environment off Runway 09's departure end (heading 090°) is open developed land (parks, large lots) and pasture — good forced-landing terrain. The risk is not the runway length; it is the pilot's decision-making during the approach and landing. A stable approach at Vref (70 KIAS), a normal flare, and smooth braking will always result in a safe landing. A high-energy approach, an extended flare, or a late go-around decision will consume runway distance and threaten an excursion.
The real accidents cited above occurred at other airports and in other contexts — NOT at KBKV. This scenario is localized to KBKV to make the runway length and off-field environment real and consequential for you as a student here. The lesson is universal: energy management on approach and landing is the pilot's responsibility, and the DA40's efficient airframe demands discipline.
Key lesson — The DA40's composite airframe is slippery and efficient — it floats in ground effect and holds energy well. Vref (70 KIAS) on short final is not a suggestion; it is the speed that ensures the shortest touchdown distance and the most runway remaining for rollout and braking. An extended flare, excess speed, or a late go-around decision will consume runway distance quickly. At KBKV, Runway 09 is 7,001 ft long — plenty of runway for a normal landing, but not for a high-energy approach. Stable approach, Vref on short final, normal flare, smooth braking — that is the standard.
Debrief — teaching points
Vref (70 KIAS) is the target speed on short final for the DA40.
Vref for the DA40 is 70 KIAS. This is the speed that ensures the shortest touchdown distance and the most runway remaining for rollout and braking. Landing above Vref increases float and touchdown distance. Landing below Vref risks a stall or hard landing. On short final, maintain 70 KIAS. Do not chase the glide slope with speed changes; use pitch and power to manage the descent rate and altitude, and trim to hold 70 KIAS.
The DA40 floats in ground effect — energy management is critical.
The DA40's composite airframe is slippery and efficient. In ground effect (below 50 ft AGL), the airplane floats and holds energy well. A long flare at Vref will result in a long float down the runway. This is not a defect; it is a characteristic of the type. Plan for the float. If the float is excessive and the runway is being consumed, slip to increase descent rate or go around. Do not let the float surprise you into a late go-around decision or a hard landing.
A go-around from short final consumes runway distance — plan ahead.
If you decide to go around from short final (300 ft AGL or below), you are committing to a maneuver that will consume runway distance during the descent and the climb-out. At 300 ft AGL, a go-around will use 1,500–2,000 ft of runway before the airplane is climbing away. At 15 ft AGL, a go-around is marginal and the runway is directly below. Plan your approach so that by 300 ft AGL, you are committed to landing. If you are unstable at 300 ft, go around early. Do not abort a go-around to land with insufficient runway remaining — that is how runway excursions happen.
Aborting a go-around to land is a trap — avoid it.
The NTSB GAA19CA582 accident involved a pilot who initiated a go-around from short final, then decided to abort it and land. The decision to abort without adequate runway distance to safely stop the airplane resulted in a loss of control and runway excursion. Once you commit to a go-around, complete it. Do not abort a go-around to land unless you are certain you have adequate runway distance and the approach is stable. If you are in doubt, complete the go-around and return for another approach.
Directional control during rollout is the pilot's responsibility.
The DA40's fixed gear and efficient airframe mean that directional control during rollout is entirely the pilot's responsibility. Crosswind landings require active rudder input to maintain alignment with the runway. A bounce or drift during landing can quickly become a loss of directional control if the pilot does not correct immediately with rudder and aileron. Maintain directional control throughout the rollout — do not relax until the airplane is stopped.
