Aircraft speed? It’s all about airspeed baby 🙂

Why do you sit on the left and not the right? Or sit on the right but not the left?

*depending on if the wings move

What has propeller thrust have to do with generating lift?

If I were to walk along one of those conveyor belts you find in an airport and maintain an overall net zero velocity (no back or forward displacement from a fixed relative position) will I feel any air passing my body? No? How then will any air velocity pass the wings to generate lift ?

Lift (by the way) = half rho x V squared x Coeff of Lift x planform surface area.

Yes you will get some air passing over the wings from the prop but the premise of remaining stationary on the belt is on par with me applying full power on the PA28 with the parking brake set. As much as I would like to take off there and then, I still needs acres of runway to take off. 😀

Does an aircraft generate any lift when the net velocity of air (in this case) passing the wings is zero?

ZRX – you’re a very naught person! 😀

Remember velocity is a vector not a scalar variable.

Hi Roy, who are you thinking of flying with? The Flight Centre at Halfpenny Green?

It can’t hurt to start genning up on the books, but it largely depends on how much information gets absorbed and how able you are to tackle the (devilishly phrased) CAA exams. Ground helps with that to a degree. Once you’ve done a subject a book called the “PPL Confuser” will help you tackle the questions. If you pop over to the airside part of the Flight Centre, I know they sell copies.

A decent school will support you through your PPL. If not, start worrying! 😀

Yes, the “Podington big picture” is in Hangar 3.

There’s some great wartime colour footage of life at Podington on a video entitled “Doc Furniss War” that I obtained from Twinwood Museum. It’s well worth hunting down a copy.

Thanks Rob.

Me neither Pagen. Is it still displayed? Where is it hiding?
