Float and Drift at Brooksville
Excess approach energy, a slippery airframe, and the DA20's ground-effect float — managing the landing when the airplane won't settle
The scenario
Departing Brooksville–Tampa Bay Regional Airport (KBKV), Brooksville, FL — Runway 09, landing after a local training flight. Elevation 76 ft MSL; the runway is essentially at sea level.
It is a breezy Florida afternoon: OAT 26°C, wind 150° at 12 gusting to 18 knots. Runway 09 is aligned 090° magnetic — a crosswind of roughly 8–10 knots, gusting to 14. Visibility 10 SM, scattered clouds at 3,500 ft. VFR, but the gusts are noticeable and the crosswind is at the edge of the DA20's demonstrated crosswind capability (roughly 10 knots in calm air, less in gusts).
You are on a 3-mile final for Runway 09, descending through 800 ft AGL at 75 KIAS (Vy, best rate of climb speed — slightly fast for final, but you are still configuring). The runway is ahead, aligned 090°. You are planning to land and return to the ramp.
Aircraft: Diamond DA20-C1, solo, within limits. Fixed gear, fixed-pitch prop, fuel-injected Continental IO-240, steam panel. The DA20 is a light, slippery composite airframe — it floats in ground effect and is sensitive to pitch and roll control inputs. The nosewheel is castering and requires differential braking for directional control on rollout.
Pilot: you — a Private or early Commercial pilot, current, roughly 150–250 hours total. You have flown the DA20 for 20–30 hours. You are familiar with the airplane's tendency to float, but today's crosswind and gusts are adding complexity to the approach.

The decision
Before we get into the decision tree — what do you already know about the DA20's landing characteristics and crosswind handling? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB WPR20CA305 (2020): A Diamond DA20 on an instructional flight bounced during landing and veered left during a go-around attempt. The student pilot did not abort the landing after the bounce — instead, the student tried to land again. The airplane veered left, exited the runway, and impacted uneven terrain. The probable cause was the student pilot's improper landing flare and delayed remedial action to abort the landing, which resulted in a loss of aircraft control and runway excursion.
NTSB GAA19CA490 (2019): A Diamond DA20 flown by a student pilot on a first solo flight experienced right yaw during the third approach that could not be corrected with rudder input. The student attempted to abort the landing (go-around), but the aircraft continued to descend with right yaw, exited the runway, and struck rough terrain. The probable cause was the student pilot's failure to maintain the runway heading during the attempted aborted landing, which resulted in a runway excursion.
NTSB GAA19CA330 (2019): A Diamond DA20 student pilot flared too early during a crosswind landing, ballooned (pitched up and climbed), and drifted left. When the instructor called for a go-around, the student maintained a strong grip on the controls, preventing the instructor from making control inputs. The airplane veered left, exited the runway, and struck runway lights. The probable cause was the student pilot's failure to maintain runway heading and refusal to relinquish the flight controls to the flight instructor in gusting, crosswind conditions.
NTSB WPR11CA099 (2011): A Diamond DA20C1 drifted left during landing rollout and struck a snow bank after the left main tire caught the bank edge. The probable cause was the pilot's failure to maintain directional control during landing.
The consistent thread across all these accidents: the DA20 is a light, slippery composite airframe that floats in ground effect. A flare that is too high or too aggressive causes the airplane to balloon and float farther down the runway. In crosswind conditions with gusts, the airplane drifts. The pilot must either (1) slip the airplane to increase descent rate and correct the drift, (2) go around if the approach is unstable, or (3) use differential braking during rollout to correct drift — the DA20's castering nosewheel requires differential braking, not aileron input. The accidents all involved a failure to recognize instability, a failure to go around, or a failure to use proper directional control technique during rollout.
All of these real accidents occurred at other airports and in other training environments — NOT at KBKV. However, KBKV's own accident history shows HARD_LANDING (26.9%), FORCED_LANDING (11.5%), and RUNWAY_EXCURSION (11.5%) as the dominant patterns. The off-field environment at KBKV is good — mostly open developed (parks/large lots), pasture/hay, and medium development off all runway ends. A runway excursion at KBKV is survivable if the airplane exits onto the open areas. But the lesson is the same: recognize instability, go around if needed, and use proper directional control technique.
The real events cited above occurred at other airports — NOT at KBKV. The scenario is localized to KBKV to make the crosswind and the off-field environment real and consequential for you as a student here.
Key lesson — The DA20 is a light, slippery composite airframe that floats in ground effect and is sensitive to pitch and roll control inputs. In crosswind conditions with gusts, a flare that is too high or too aggressive will cause the airplane to balloon and float. The correct responses are: (1) slip the airplane (lower the wing into the wind, apply opposite rudder) to increase descent rate and correct drift, (2) go around if the approach is unstable or the float is excessive, or (3) use differential braking during rollout to correct drift — the DA20's castering nosewheel requires differential braking, not aileron input. Do not try to force the airplane onto the runway. Recognize instability early and go around.
Debrief — teaching points
The DA20 floats in ground effect — it is a light, slippery composite airframe.
The DA20's composite construction and light weight mean it floats significantly in ground effect. A flare that is too high or too aggressive will cause the airplane to pitch up and climb — a balloon. The airplane will not settle onto the runway; instead, it will float down the runway, consuming distance and altitude. In a 7,001-ft runway like Runway 09 at KBKV, a float of 1,000–2,000 ft is manageable. But in a crosswind with gusts, the float is compounded by drift. Recognize the float early and either slip the airplane to increase descent rate or go around.
A forward slip (lower the wing into the wind, apply opposite rudder) is the correct technique for managing float and drift in the DA20.
The forward slip increases the descent rate by increasing drag and reducing lift. In a crosswind landing, lowering the wing into the wind and applying opposite rudder both increases descent rate and corrects the drift. This is a valid and effective technique for the DA20 in crosswind conditions. Practice it in calm air first, then use it in crosswind approaches. The slip is not a last-resort maneuver — it is a standard technique for the DA20.
The DA20's nosewheel is castering — it requires differential braking for directional control during rollout.
During landing rollout, the nosewheel is castering (free-swiveling). Aileron input does not correct a ground-roll drift — only differential braking does. To correct a left drift, apply right brake (which slows the right main gear and yaws the airplane right). To correct a right drift, apply left brake. This is a critical technique for the DA20. Many pilots try to use aileron to correct a ground-roll drift, which does not work and can make the situation worse. Know this technique before you land the DA20.
A bounce after touchdown means the landing is unstable — go around.
If the airplane bounces on touchdown, the landing is unstable. Do not try to land again from 5–10 ft AGL. Go around immediately. A bounce is a sign that the flare was too aggressive, the descent rate was too high, or the approach was unstable. Trying to land again from a low altitude in an unstable condition is a setup for a runway excursion or loss of control. The NTSB accident WPR20CA305 involved a bounce followed by an attempt to land again — the result was a runway excursion and impact with terrain. Go around.
Recognize instability early and go around — do not try to force the landing.
An unstable approach is one that is fast, high, floating, drifting, or any combination of these. If you recognize instability at any point on final approach, go around. A go-around is not a failure — it is airmanship. The cost of a go-around is a few minutes and a bit of fuel. The cost of a forced landing is an accident. The NTSB accidents GAA19CA490 and GAA19CA330 both involved pilots who did not go around when they should have. Recognize instability early and go around.
In a crosswind with gusts, the DA20's demonstrated crosswind capability is reduced — plan accordingly.
The DA20's demonstrated crosswind capability is roughly 10 knots in calm air. Gusts reduce that margin significantly. A 12-knot wind gusting to 18 knots (as in this scenario) is at or beyond the airplane's capability. Plan for a longer runway, a lower approach speed, and a slip technique if needed. If the crosswind is beyond your personal minimums, go around or divert to a runway with a better alignment. The NTSB accident GAA19CA330 involved a crosswind landing in gusting conditions — the student pilot did not go around when the approach became unstable.
