Ryanair flight diverted to Berlin The July incidents prompted criticism of the airline by pilots" unions. IALPA, the Irish pilots" union, alleged that the airline put pressure on flight crews to carry the minimum amount of fuel required, in an attempt to cut costs, while the European Cockpit Association said that pilots were being encouraged to make decisions based on "factors other than safety." Ryanair rejected the claims, and last week the Irish Aviation Authority (IAA) - following discussions with Spanish authorities - ruled that all three aircraft took off with fuel "in excess of legal requirements." However, the IAA did suggested that Ryanair issue new guidance to staff with regards to fuel when flying into busy airports, particularly in poor weather, where diversions were likely. Meanwhile, several passengers are considering legal action against the airline after they were hurt on a Ryanair flight to East Midlands Airport in April which suffered from cabin pressure problems. The flight, from Bergamo, was forced to make an emergency descent of around 20,000ft. Law firm Irwin Mitchell, which is representing the passengers, said further problems with cabin pressure had occurred on two other Ryanair flights, from Milan to Brussels Charleroi in February, and, most recently, from Madrid to the Canary Islands on September 7. Jim Morris, a former Boeing pilot and a partner at Irwin Mitchell, said: "To see such a significant number of potentially serious pressurisation problems occur in such a short space of time is clearly a major concern and something that obviously needs to be fully examined." A Ryanair spokesman described the claims as "completely baseless." He added: "While Ryanair has suffered 3 depressurisation incidents in 2012, this is out of over 450,000 flights this year to date which is an extremely low occurrence rate. For example, Iberia suffered a similar depressurisation incident in Madrid last week, as have other airlines in recent weeks. In all cases, the oxygen masks are lowered as a safety precaution, but there is no threat to safety. Any legal action will be fully and vigorously defended.
