Gusts on Short Final
Crosswind landing in gusty conditions — when to commit to the go-around and when directional control is already lost
The scenario
Departing St. Petersburg Clearwater International Airport (KPIE), Pinellas Park, FL — Runway 18, a 9,730 ft concrete runway aligned 171° magnetic. Elevation 11 ft MSL. You are a commercial pilot with 650 hours, current and proficient. This is a local instructional flight in a Diamond DA40 with a student pilot in the right seat.
Weather: VFR, scattered clouds 3,500 ft, visibility 10 SM. Wind from 200° at 18 gusting to 28 knots. Runway 18 is aligned 171° magnetic; the wind is a 29° crosswind from the right, gusting 10 knots above the mean. The DA40's demonstrated crosswind capability is 13 knots. You are at 15–18 knots sustained, with gusts to 28 knots — well above demonstrated limits. The tower is open (0600–2300 local); you are in Class D airspace.
You have been circling the field for 15 minutes, watching the wind. The gusts are erratic — some cycles are manageable, others are not. The student is current and has logged 12 landings in the DA40, all in light wind. You have 45 minutes of fuel remaining. The decision point is now: attempt the landing in these conditions, or divert to a nearby airport with better wind alignment.
Aircraft: Diamond DA40, full fuel, within CG and weight limits. Constant-speed prop, fuel-injected Lycoming IO-360, fixed gear, G1000 glass panel. Best glide 73 KIAS. Approach speed (short final) 70 KIAS. Landing distance required (no wind, sea level) approximately 1,500 ft. Runway 18 is 9,730 ft — plenty of distance if you land on the numbers and stop cleanly.
The student is watching you. The tower is waiting for your decision. The wind is gusty but not impossible. Many pilots would attempt this landing. The question is whether you should.

The decision
Before the decision tree — what is your baseline understanding of crosswind limits and loss-of-control risk in gusty conditions? (Pick all that apply.)
What the record shows
What the NTSB files show
NTSB ERA21LA039 (2020): A Diamond DA40 on a 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. The wind was 18 knots gusting to 28 knots — a crosswind component that exceeded the aircraft's demonstrated capability.
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 accident resulted from the pilot's decision to abort the go-around without adequate runway distance and his failure to accurately communicate his intentions to ATC. The lesson: a go-around decision must be made early, with adequate altitude and airspeed to execute safely.
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 lesson: directional control must be maintained throughout the landing roll and taxi.
Regional precedents (GAA17CA105, ERA17CA149, GAA16CA149, CHI02TA149) show a consistent pattern: loss of directional control during landing in crosswind conditions, often triggered by a gust, bounce, or wind shift. The common factor is that the pilot continued the approach or landing despite marginal or deteriorating directional control, rather than aborting early.
The real accidents cited above occurred at various airports — NOT at KPIE. KPIE has its own accident history dominated by loss-of-control events (21.2% of the field's accidents are loss-of-control inflight; 15.2% are loss-of-control ground). The scenario is localized to KPIE to make the crosswind decision real and consequential for you as a student here.
The consistent thread across all these events: crosswind limits are not guidelines. The DA40's demonstrated crosswind capability is 13 knots. Exceeding it in gusts is a known risk factor. The decision to divert or abort the approach early — before the situation becomes unstable — is a mark of professional airmanship. A bounce or gust on short final or during rollout can trigger loss of directional control. Once directional control is marginal at low airspeed, aggressive control inputs can worsen the situation. Accepting a runway excursion and braking to a stop is safer than attempting recovery that risks collision or cartwheeling.
Key lesson — Demonstrated crosswind limits are limits, not guidelines. At KPIE, Runway 18 is aligned 171° magnetic. A wind from 200° is a 29° crosswind. Sustained 15–18 knots with gusts to 28 knots exceeds the DA40's demonstrated 13-knot limit. The decision to divert or abort the approach early — before the approach becomes unstable — is a mark of professional airmanship. A bounce or gust on short final or during rollout can trigger loss of directional control. Once directional control is marginal at low airspeed, aggressive control inputs can worsen the situation. Accepting a runway excursion and braking to a stop is safer than attempting recovery that risks collision or cartwheeling.
Debrief — teaching points
Demonstrated crosswind limits are limits, not guidelines.
The DA40's demonstrated crosswind capability is 13 knots. This is the maximum crosswind component the airplane has been tested and certified to handle safely. Exceeding it — especially in gusts — is a known risk factor in runway excursions and loss-of-control accidents. At KPIE, Runway 18 is aligned 171° magnetic. A wind from 200° at 18 gusting to 28 knots is a 29° crosswind of 15–18 knots sustained with gusts to 28 knots — well above the demonstrated limit. The decision to divert or abort the approach early is a mark of professional airmanship, not a sign of weakness.
Gusts add to the crosswind component — plan accordingly.
A gust of 10 knots above the mean wind adds 10 knots of effective crosswind. If the mean wind is already at or near the demonstrated limit, gusts exceed the limit by definition. In the scenario, the mean wind is 18 knots with gusts to 28 knots — a 10-knot gust range. The sustained crosswind is 15–18 knots; the gust crosswind is 23–28 knots. Plan to divert or abort if the sustained crosswind is more than 10 knots, leaving a 3-knot margin for gusts.
The bounce is a critical moment — directional control is marginal.
A landing bounce in crosswind conditions is a high-risk moment. The airplane is slow (50–60 KIAS), directional control is marginal, and the wind is still present. A second bounce or a gust during the rebound can trigger loss of directional control. The decision to go around after a bounce — rather than attempting a second touchdown — is the safer choice. At 50 ft AGL with marginal directional control, a go-around is executable; attempting a second touchdown in gusts is not.
The go-around decision must be made early — before the approach becomes unstable.
The ideal go-around decision is made on base or early on short final — before the approach becomes unstable and the go-around itself becomes marginal. A go-around at 100 ft AGL is survivable but marginal on altitude and airspeed. A go-around at 50 ft AGL after a bounce is even more marginal. A go-around at 200 ft AGL, before the approach becomes unstable, is the safest option. If you are uncomfortable with the wind on short final, go around early.
At low airspeed with marginal directional control, accept the excursion and brake to a stop.
Once the airplane is in a runway excursion at low airspeed (50 KIAS), aggressive control inputs can worsen the situation — the nose may swing but the fuselage continues to drift, causing a skid. Aggressive rudder input at low airspeed can lead to cartwheeling or collision. The safer response is to accept the excursion, reduce throttle to idle, and apply wheel brakes smoothly. The airplane will slow and stop off the runway, but it will remain upright and intact. This is the lesson from NTSB ERA21LA039: the pilot's attempt to recover from the drift with aggressive rudder led to a cartwheel and collision with a taxiway sign.
Runway 18's off-field environment is medium development and parks — collision risk, not ditching.
Off Runway 18's climb-out (heading 171°), the off-field environment is medium development, open developed (parks/large lots), and dense development. A runway excursion to the left (north) of Runway 18 is a collision risk — taxiway signs, buildings, parked aircraft. This is not a ditching scenario; it is a collision scenario. The importance of maintaining directional control throughout the landing and rollout is critical.
