A pilot is person who holds the responsibility to make your flight safety. This safe journey is possible with few of the devices makes it possible. Without these devices a flight can be in danger and if not at the best quality then having these devices makes them worthless. The wish list of pilot, thus have the following devices on the top: buy Lightspeed Zulu headsets designed for providing focused diminution noise in most critical ranges, the cheap airplane safety wire though cheap but helpful for tightening the loose ends of fastening device, cheap Vertex radios- for maintaining the contact and clear touch with the land.
There has always been confusion about the word cheap. It is always not necessary that when it comes to say cheap it means low quality. A cheap airplane safety wire is worth because they are used only once and the safety wires are meant to be cheap. Also having high cost vertex radio will not be seemingly important that will function properly, the cheap Vertex radios functions in the same way as the highly cost one, or you can say much better than that. So the cost never decides the functionality always, sometimes having a cheap or inexpensive part may prove more useful than the costly and expensive one.
