Spanish investigators found that an Iberia Express Airbus A320 crew declared a fuel emergency after diverting and realizing their assigned runway required a much longer route than anticipated. Following a missed approach at Tenerife North, the crew diverted to Tenerife South expecting a direct arrival, but the active runway added nearly forty nautical miles to their flight path. This incident underscores why pilots must thoroughly verify active runways and routing requirements when calculating alternate fuel reserves.
Read the full take
The Spanish accident investigation agency recently highlighted critical flight planning vulnerabilities following a diversion that left an Airbus A320 dipping into its final reserve fuel. The flight originally departed Madrid with slightly more fuel than dispatched but encountered prolonged holding and a missed approach at its primary destination of Tenerife North. When the flight crew opted to divert to Tenerife South, they assumed they would be landing on a runway that offered a direct approach. However, air traffic control assigned the opposite runway, extending the diversion route by nearly forty nautical miles. While the crew attempted to negotiate shortcuts to preserve their final reserve fuel, traffic conflicts prevented controllers from accommodating the requests immediately. Ultimately, the pilots had to declare an emergency to secure priority routing, landing with fuel slightly below the required reserve minimums. For the aviation community, this event exposes the hidden risks of using overly optimistic assumptions during high workload scenarios. Fuel planning for alternate airports often relies on historical averages or the shortest possible routing, which can quickly fall apart in dynamic weather environments. Iberia Express has since amended its operational procedures, extending the standard planned flight time for this specific diversion route to account for varied arrival procedures. Furthermore, the internal review noted that dispatchers should have recognized the deteriorating weather trends and planned for a second alternate. Whether you are flying a training light aircraft or a modern airliner, this scenario emphasizes the necessity of maintaining situational awareness regarding alternate airport operations well before a diversion becomes necessary. Always anticipate the worst-case arrival routing rather than hoping for a direct approach.
