Q&A: The Flying Bulls Answer Your Questions
In recent weeks, we have received many questions from aircraft enthusiasts, interested parties, and friends of the Flying Bulls. We are happy to answer them for you here:
- How are the aircrafts chromium-plated so beautifully and why?
The aircrafts of the Flying Bulls are actually not chromium-plated. Only two models - the P38 and the B52 - were completely polished, while the DC-6 was partially polished. This process makes the aircrafts appear as if they have been chromium-plated. All the other Flying Bulls are painted.
The Bell Cobra has a small “pendulum” mounted on its roof. What is it used for?
This pendulum was once an important element of the flight data computer. Today, it has no function.
- How does one determine when an engine (for example, that of the P38) needs to be replaced?
An engine needing to be exchanged depends on a number of factors, such as the number of flight hours and analysis of the engine’s oil. In addition, every engine is regularly examined during static tests. Furthermore, pilots often “feel” when an engine has reached the end of its life, for example when a drop in performance is noticeable.
- What is a tandem hydraulic system?
A tandem hydraulic system exclusively serves security purposes. When the main hydraulic system fails, the “standby” system takes over all functions. This is why the entire system is referred to as a tandem hydraulic system.
- How come one of the four Douglas DC-6’s propellers is - at times - not synchronised with the others? Does this affect flight behaviour?
This can happen for a brief period of time, but the propellers are swiftly re-synchronised by the so-called “propeller synchroniser”.
- How can one obtain spare parts for historic aircrafts?
Every plane or helicopter needs spare parts sooner or later, even with the best possible maintenance and servicing. It is not easy to obtain these spare parts, but there are several ways for going about this business:
- One can repair defective parts for reuse.
- From time to time research and contacts can lead to the discovery of old stocks.
- If it proves impossible to repair old parts or find old stocks, one needs to try and replicate the necessary parts.
- How does one define the limits of planes and helicopters?
The limits of each plane or helicopter are determined by the respective manufacturer and need to be respected at all times.
The Flying Bulls are grateful for the many questions!
