Sir, Your correspondent, C H Standfield, must be sure of his facts before impugning the professionalism of the crew of the KLM flight he travelled on (letter, 9 November).
Aircraft arriving at Heathrow from the north-west and north-east normally route initially towards radio beacons at Bovingdon or Lambourne respectively.
From there air traffic control gives them radar vectors (headings to fly) towards the airport's instrument landing system beams.
The turn on to the ILS localiser beam is usually over the City of London. In other words, a right-wing bank over the City is the norm for traffic approaching from these directions.
