Later that night, in a Reykjavik hotel, Lena opened her laptop. A message from the training department: “Reminder: Your ATPL theoretical knowledge revalidation exam is in two weeks. Topics: Mass & Balance, Flight Planning, Meteorology, Performance, Human Factors.”
Captain Lena Ndiaye loved the silence of Flight 712. At 37,000 feet over the North Atlantic, with the autopilot humming and the stars sharp above the clouds, flying felt less like a job and more like a conversation with physics. But tonight, the conversation was turning into an argument. atpl questions review
This was the trick question from every ATPL exam: Never rely on the first alternate if it’s marginal. Always carry final reserve fuel (30 minutes at holding speed) which is another 1,600 kg. Their 3,600 kg remaining after hold was not 3,600 kg of divert fuel—it was 2,000 kg of divert fuel plus 1,600 kg of final reserve. Later that night, in a Reykjavik hotel, Lena
Elias’s eyes widened. “We did our CAT II check six weeks ago. Yes.” At 37,000 feet over the North Atlantic, with
Elias nodded, sweating. “Hold fuel at FL370: 2,400 kg/hr. At 5,000 feet: 3,200 kg/hr. For thirty minutes, that’s 1,600 kg. We have 5,200 kg total remaining. That leaves 3,600 kg for the divert to Vagar. Distance: 280 nautical miles. At our planned speed, that’s 1,800 kg. We have exactly double the required. Safe.”
“We hold at BIKF for thirty minutes, then divert,” she told Elias. “But we need to calculate the fuel to hold at 5,000 feet, not at FL370. Different consumption. ATPL rule: fuel flow increases by 20% per 10,000 feet descent due to higher drag at low altitude.”
