Holidays!

 

Good afternoon my aeronautics enthusisats,

It’s been a very long time since my last blog and I must say that this is one of my latest blogs. In just one month we will have finished all my exams and the summer holidays will start also. I’m very excited to finish the course and start my practises as soon as possible.

During the last weeks we have been doing some practises related with module 5, digital techniques and module 11. My favourite one’s have been related with the ones of module 11 which were about the electrical system of the Cessna 441. I’m really sorry because I couldn’t be able to make a lot of photos but I will try to show you some images to explain everything.

The main problem that we have on the Cessna it is that we don’t have electrical power to energize the aircraft. The first thing we did was restoring the batteries and try to energize the aircraft. At the beginning when we connected them, most of the systems of the aircraft worked but the problem came after as the batteries cannot supply electricity during a long time as they get discharged.

Our mission was to supply energy with the external power connection. We have a battery charger of car batteries that can supply 24 volt but only 50 amp and the aircraft required 28 volt with 500 amp or more. As you can see our external power wasn’t enough to energize the whole aircraft but even though, we managed to connect the battery charger and supply some electricity to the aircraft. You were able to energize an small amount of systems but not the entire aircraft, but at least it was better than nothing! We are still waiting to the school to buy an small generator to be able to energize the aircraft properly, I hope they bought it soon for further practises for new courses.

Another practise that we did related with the electricity was repairing the circuit breakers of the electrical system. Most of them were a little bit sticky as it been a long time since there were pulled out or in, so we lubricated them to make them reusable. The circuit breaker is a protection of the wiring to avoid overcurrent or short cirucuit, that’s why it is important that they work properly. Some of them were broken so we managed to replace them and make them serviceable again. We opened one to see why it wasn't working, it was fried inside due to a short ciruit.We changed them with circuito breakers from the old Coronado which is an aircraft from the 70’s, you can see that some things don’t change with the years…

Finally, let’s talk a little bit about my eastern holidays. The first days, I had to work at the airport and I must say that some days were extremely horrible as there was a lot of traffic because of the holidays. We were running in all directions during all the shifts. I also had the opportunity to go inside the hangar of Globalia with my father. Notwithstanding, the remaining days I spent them at home because I got covid just 3 days before they were removing the mask in the interiors. The first two and three days I’ve been quite bad but mostly due to mucus in the nose and lungs but it was most like a typical cold. 

At least before picking up the covid I had time to do panades and robiols with my family and they were very tasty and delicious!

I hope you learnt new things and aviation and enjoyed reading my blogs as always. Now it is the last pull for finishing the course and I hope everything goes well as always.

See you on my last blog and happy eastern holidays!!
