On 13 March 2011, a Turkish Airlines’ Boeing 737-800 stopped climb shortly after take off after misreading the SID chart. After levelling at 450 feet agl, it continued following the lateral part of the SID only until ATC re-iterated the requirement to climb after resolving a temporary loss of contact due to an un-instructed premature frequency change. It was found that the crew had received but apparently not responded to an EGPWS PULL UP’ Warning. It was concluded that there was an opportunity to improve the clarity of UK SID charts to aid pilots with limited English language skills.
