During the peak summer months of July and August, our operations at LEJE Granada are temporarily suspended owing to the elevated temperatures prevalent in Spain. This precautionary measure is implemented to ensure both the safety of our pilots and the optimal mechanical maintenance of our aircraft. The decision is particularly influenced by the altitude of Juan Espadafor Aerodromo, standing at 2500 feet, wherein rising temperatures correspondingly elevate the Density Altitude of the airfield. Notably, temperatures consistently exceed 38 degrees Celsius during this period, as illustrated in the accompanying chart.
As indicated in the chart, the altitude of the airfield can surpass the experience level of many UK pilots. Consequently, aircraft performance is notably diminished, potentially leading to disconcerting experiences, particularly for those unfamiliar with the sensation of ´sink´ upon the release of a flap, which could pose safety risks in certain scenarios.
In the summer of 2023, one of our Socata Rallyes, piloted by a highly experienced Iberia Captain who regularly rents aircraft from our fleet, demonstrated an aircraft that usually takes off in under 300 meters, requiring over 900 meters to takeoff.
In hot weather conditions, the aircraft are also susceptible to overheating, a factor particularly crucial for low-hour pilots to understand and effectively manage. This concern was underscored during a climb in the summer of 2023, as experienced firsthand by the Safety Pilot and myself (Clifford Marker), when ascending from 1000 feet above ground level (AGL) below the Malaga Terminal Control Area (TMA) to 6500 feet to navigate terrain clearance.
As the aircraft's temperature rose, its engine power diminished, leading to a noticeable loss of power. Promptly notifying Air Traffic Control (ATC), we mitigated the situation by reducing power, ensuring a rich mixture, and allowing the engine to cool. The issue stemmed from warm air ingestion into the engine due to low altitude, compounded by the engine's lack of air cooling during ascent. With increased altitude attained, the aircraft's performance swiftly returned to its standard levels.
ATC services in Spain excel in providing assistance during General Aviation (GA) operations, distinguishing themselves, along with their French counterparts, regarding GA flying. Do not be afraid to speak to ATC and explain your situation, but more importantly "Aviate, Navigate, Communicate' Fly the plane, speak about it when you have the situation under control. This is why we always recommend a Safety Pilot when you are a low hour pilot.
