Rough Climb Over Tampa Bay

Departing Tampa International Airport (KTPA), Tampa, FL — Runway 10, climbing out on a 092° heading. Elevation 26 ft MSL; the runway is essentially at sea level. You are a commercial pilot with a high-performance endorsement, current in the Cessna 182 Skylane. Solo, full fuel (82 gallons usable), within CG and weight limits.

It is a hazy Florida afternoon in late spring: OAT 27°C, dew point 21°C, altimeter 29.92. Scattered clouds at 2,500 ft, light rain shower two miles to the northeast. Visibility 8 SM. Classic Gulf Coast conditions — warm, moist, and exactly the environment the FAA icing probability chart marks as 'serious icing at glide power, moderate icing at cruise power.' The Continental O-470 is carbureted; there is no fuel injection.

You are 500 ft AGL, climbing through 85 KIAS (Vy, best rate of climb), heading 092°, when the engine begins to run rough. Power is noticeably down — the tachometer is dropping and the manifold pressure is unwinding. The dense development of Tampa sprawls ahead and to the sides. KTPA tower is active (24-hour ATCT); you are in Class B airspace (ceiling 10,000 MSL). The field is behind you.

Aircraft: Cessna 182 Skylane, Continental O-470 (230 hp), constant-speed prop, cowl flaps, carbureted, fixed gear, fuel selector BOTH. Nothing was written up; the airplane was airworthy at departure. You did not apply carburetor heat during the run-up because the engine ran smoothly. You did not apply it after takeoff because you were heads-down on the climb and the workload of managing the constant-speed prop and cowl flaps occupied your attention.

Pilot: you — a Commercial pilot, current, roughly 800 hours total with 150 hours in the C182. You are familiar with the airplane's systems and performance. You know the off-field environment off Runway 10 is marginal — dense development, parks, and wooded wetland. There is no open field, no road, no water. An engine failure on the Runway 10 departure at 500 ft AGL is a forced landing into developed terrain.

NTSB CEN19FA008 (2018): A Cessna 182 on a cross-country flight from California to New Mexico encountered partial engine power loss due to induction system icing. The pilot attempted to reach Albuquerque but could not maintain altitude. The probable cause was partial loss of engine power due to induction system icing, with a contributing factor: a fractured carburetor heat control cable that rendered the carburetor heat inoperative. The pilot had no recovery option.

NTSB NYC07FA145 (2007): A Cessna 182C on an instructional flight experienced carburetor icing, resulting in loss of engine power. The pilot and instructor failed to maintain airspeed during the forced landing, resulting in a stall. The probable cause was carburetor icing and the pilots' failure to maintain adequate airspeed (best glide speed) during the forced landing. Both occupants were killed.

NTSB ATL04FA069 (2004): A Cessna 182A on a personal flight lost engine power due to carburetor ice during cruise and made a forced landing in a field near Traphill, North Carolina. The probable cause was loss of engine power due to carburetor ice, with contributing factors including atmospheric conditions conducive to carburetor icing.

NTSB WPR25LA175 (2025): A Cessna 182P descended at low power without carburetor heat in conditions conducive to icing. The engine lost power on base leg, and the pilot made a forced landing on a gravel bar, damaging the nose gear and forward fuselage. The probable cause was the pilot's failure to use carburetor heat, which resulted in a loss of engine power due to carburetor icing.

The real accidents cited above occurred at other airports and in other aircraft — NOT at Tampa International Airport. KTPA has its own accident history (see field dominant patterns: forced landing 22.2%, loss of control 11.1%), but these specific carburetor ice events happened in California, New Mexico, North Carolina, and elsewhere. The scenario is localized to KTPA to make the off-field environment real and consequential for you as a student here.

The consistent thread across all these events: carburetor ice in the C182 is insidious. It builds gradually, the first symptom is roughness and a dropping tachometer / manifold pressure (not a dramatic power cut), and by the time it is obvious, it may be too late for a comfortable recovery. The fix — full carburetor heat, immediately, at the first sign of roughness in conducive conditions — is simple. The failure is always a delay. And in NYC07FA145, the failure was compounded by a loss of airspeed during the forced landing — the stall was the killing blow.

Off Runway 10 at KTPA, the off-field environment is dense development, parks, and wooded wetland — marginal at best. An engine failure on the Runway 10 departure at 500 ft AGL is a forced landing into built-up terrain, not open field or water. The C182's higher wing loading and heavier nose mean a fast or flat approach floats and the nose drops into a porpoise — maintaining 70 KIAS best glide speed and a stable descent rate is non-negotiable.
