    RAF Airbus A400M coming into land at Northolt. It had flown from Chicago and seems to have delivered something before taking off again for Brize Norton Oxfordshire. The takeoff at around 3:00 is quite spectacular.

    Impressive looked a short take off.

    I hope somebody can explain why the props were going in different directions? Maybe Prefect since he was a flyboy

    This counter-rotation characteristic is known as Down-Between-Engines (DBE) and the A400M will be the first aircraft ever to use such a configuration. The advantages of DBE have far-reaching effects both aerodynamically and structurally. Firstly, airflow over the wings is symmetrical, improving lift characteristics and the lateral stability of the aircraft. Secondly, DBE allows for an optimum wing design by eliminating most of the effects of torque and prop-wash on each wing, concentrating the airflow over the most efficient portion of the wing located between the engines. DBE also reduces the “critical engine” effect of severe yaw in the event of an outboard engine failure. The result allows a 17% reduction in the area of the vertical tail surface.

    Further aerodynamic advantages inherent in DBE have been found to give a 4% increase in lift from the wing at slow speed, which enables, for the same total lift, a simpler, lighter flap system to be employed. As a consequence of the lessening of the aerodynamic forces applied to the flaps, the surface area of the horizontal tail-plane can also be reduced by 8%.

    thanks Zippity, the props are quite mesmerising. Sometime after midnight a large aircraft rumbled through the night sky, not directly overhead but loud all the same. Flightradar24 showed it as NASA747 which was heading to ChCh airport, it landed about 00:45am after a 6 hour observation flight.

    I think they were picking something up?

    Probably the Pilot wanted some KFC and KFC management wouldn’t let him use the “Drive Through” so Ground Crew had to deliver it.

    A question for the enthusiasts:

    I go down to the airport every now and then to watch the aircraft come and go while SWMBO reads her book. I have a scanner receiver that I tune to the aircraft frequencies and every so often I hear the tower tell a plane to go to a frequency for when they go overseas and I was hoping that someone could tell me what that frequency is so I can enter it into my receiver. I think that it may be Auckland Radio but all I get when I do a search on Google is a list of Auckland radio stations which is not what I want.

    I was hoping that someone would be able to tell me what that frequency is.

    Thank you.

    Thanks very much R2x1. That is just what I was looking for, Auckland Oceanic.

    As Prefect says, I think that there may be an HF frequency.
