Okay. So I'am just having a doubt on this flight (BA359) flying from Lyon, France en-route to London Heathrow. It is flying at a way low speed of 433 km/h (234 knots) in which i think is a bit weird. It is quite far from London Heathrow before landing. But come on, the head wind is not way too much. I mean if it is way too much, the airplane will fly at TAS 700 km/h ( GS 950 km/h) corrected for a 250 km/h head wind/jet stream.
Or maybe there is an altitude restriction or instruction to fly at holding speed to finally hold at Biggin or Ockham holding stacks due to heavy inboud traffic? I'am just curious.
