Energy Management on Short Final
A Diamond DA40's slippery airframe, excess approach energy, and the decision to go around — runway excursion risk at Sarasota Bradenton
The scenario
Departing Sarasota Bradenton International Airport (KSRQ), Sarasota, FL — Runway 14, a 9,500 ft asphalt runway. Elevation 30 ft MSL. You are a commercial pilot with roughly 350 hours total, 120 hours in the DA40, conducting a supervised solo instructional flight in a school DA40. Your CFI is on the ground observing.
It is a clear, VFR afternoon: OAT 26°C, altimeter 29.98, visibility 10+ SM. Light crosswind from the left (roughly 8 knots from 100°). The tower is active (Class C, part-time 0600–0000). You have completed a 1.5-hour local flight and are returning to KSRQ for landing.
You are on a 5 nm final approach to Runway 14 (heading 134°), cleared to land. Descent is stable at 500 ft AGL, airspeed 85 KIAS, power 1,500 RPM, prop set to 2,000 RPM. The runway is in sight, long and straight. You are slightly high on the glide slope — not dangerously, but noticeably. The DA40's slippery composite airframe floats easily when energy is not managed precisely.
Aircraft: Diamond DA40, fixed gear, constant-speed prop, fuel-injected Lycoming IO-360-M1A. Vref (approach speed) is 70 KIAS; Vs0 (landing stall) is 49 KIAS. The airplane is within limits. Fuel selector is set to RIGHT tank (you switched from LEFT at 2,000 ft on descent). Flaps are at 25° (landing configuration).
Pilot: you — a commercial pilot, current, roughly 350 hours total, 120 hours in type. You are familiar with KSRQ from previous flights. You know the DA40 floats on approach if energy is not managed. You have not yet executed a go-around in the DA40 under crosswind conditions. Your CFI is observing from the ground.

The decision
Before we get into the decision tree — what do you already know about energy management and go-around execution in the DA40? (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. The pilot initiated a go-around from short final, but the runway remaining was insufficient to safely stop the airplane. The pilot cut power and applied brakes, resulting in a loss of directional control, runway excursion, and impact with a concrete barrier. The probable cause was the pilot's decision to abort the go-around without adequate runway distance and his failure to accurately communicate his intentions to air traffic control.
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. 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. However, the root cause was the landing itself — the airplane was fast and the pilot did not have adequate control during the turn.
The common thread across all three accidents: the DA40's slippery composite airframe makes energy management on approach critical. A high approach that floats, a go-around initiated too late or from too low an altitude, or a landing at excessive speed all create runway excursion risk. At KSRQ, Runway 14 is 9,500 ft long — plenty of distance for a safe landing if energy is managed correctly. But the off-field environment off Runway 14's climb-out (heading 134°) is dense development — not a safe forced-landing option. A go-around must be initiated early, from good altitude and airspeed, with a clear plan to return to the runway or divert to an alternate.
The real accidents cited above occurred at other airports and in other aircraft types — NOT at KSRQ. However, the scenario is localized to KSRQ to make the runway length, the off-field environment, and the energy-management challenge real and consequential for you as a student here.
The consistent lesson across all these events: in the DA40, energy management on approach is not optional. A high approach that floats, a go-around initiated late, or a landing at excessive speed are all precursors to runway excursion. Correct deviations early. If you are not stable by 500 ft AGL, go around. Do not try to salvage an unstable approach.
Key lesson — The DA40's slippery composite airframe floats easily on approach if energy is not managed precisely. Vref is 70 KIAS; maintain that speed on short final. If you are high on the glide slope, lower the nose early — do not wait until short final. If you are not stable by 500 ft AGL, go around. A go-around initiated early from good altitude and airspeed is safe; one initiated late from low altitude and low airspeed is marginal. At KSRQ, Runway 14 is long enough for any correctly executed approach or go-around — but the off-field environment off the climb-out is dense development. Manage energy, execute decisions early, and do not try to salvage an unstable approach.
Debrief — teaching points
The DA40's composite airframe is slippery — energy management on approach is critical.
The DA40's sleek composite design gives it excellent cruise performance, but it floats easily on approach if power is not reduced and the nose is not lowered to maintain Vref (70 KIAS). A high approach that floats is the most common precursor to a runway excursion in this airplane. Correct high approaches early — by 3 nm final — not late. If you are high at 1 nm final, you are already in trouble.
Maintain Vref (70 KIAS) on short final — do not let the airplane float.
Vref for the DA40 is 70 KIAS. This is the approach speed that gives the best combination of descent rate and control authority. Maintain this speed on short final by lowering the nose and reducing power as needed. If the airplane is floating at 75+ KIAS, you are too fast and the descent rate is too shallow. Lower the nose to increase descent rate and re-establish the glide slope.
Go-around decisions must be made early — by 500 ft AGL — from good altitude and airspeed.
If you are not stable by 500 ft AGL, go around. A go-around initiated from 500 ft AGL at 85+ KIAS is safe and straightforward: full throttle, prop to 2,500 RPM, flaps to 15°, establish a climb. A go-around initiated from 250 ft AGL at 70 KIAS is marginal — you have minimal altitude and airspeed to maneuver. A go-around initiated from 150 ft AGL at 60 KIAS is dangerous. Make the decision early.
The DA40 fuel selector is LEFT / RIGHT only — no BOTH position.
Unlike some aircraft, the DA40 has no BOTH position on the fuel selector. You must manage LEFT and RIGHT tanks actively. A mis-set selector or an empty selected tank will cause fuel starvation. On extended maneuvers like a go-around, confirm the fuel selector is set correctly. If you are unsure which tank has fuel, switch to the other tank immediately.
Off Runway 14's climb-out, the off-field environment is dense development — not a safe forced-landing option.
Runway 14 at KSRQ has a heading of 134°. The off-field environment off that climb-out is dense development and low-density development — not a safe forced-landing option. If an engine failure or other emergency occurs on the Runway 14 departure, you must return to the airport or divert to an alternate. Do not attempt a forced landing in the development. This is why early go-around decisions and energy management on approach are so critical — they give you options.
Crosswind coordination during a go-around is essential — the airplane will want to drift.
During a go-around, especially with a crosswind from the left, the airplane will want to drift left as you apply power and climb. Apply right rudder and aileron to maintain runway alignment. Do not let the drift grow — correct it immediately. At low altitude and low airspeed, a drift that grows into a bank can lead to a loss of control.
