Hi, i am new here, hello to all!

I try to understand what happes when i get into an Airspace.

For example i fly with a Cessan 172 to EDDH (Hamburg, Germany) , This Airport is Class C Airspace.

From what i understand, when i fly in Class C i must have a distance to the Clouds, for example 1000 feet above the Clouds..But how do i know what distance i have to the Clouds?

Then...I have an iPad with Skydemon APP when i flly (with MS2020) and  i come to EDDH Class C Airspace Skydemon shows a blue circle with the Information "Vertical 2500 Feet - FL100 ". What does this mean? Does it mean, when i fly over the Airport (and i dont land) i must remain 10.000 Feet? And whats the vertical 2500 Feet?

 

Thanks in Advance, Garack

You would get the cloud coverage from ATIS and other weather sites. It will tell you the cloud height and you can figure from that how high you can be.

As for your second question....if I remember correctly that would be you need to maintain a distance of 2500-10000 feet above the airport. I could be wrong so I hope someone else takes a stab at it.

First up, the moment you get off the ground, regardless of where you are, you are 'in airspace', it's the class of airspace you are in which matters. The gist of this is:

Classes A, B, C, D and E are controlled for any IFR flights in there.

Classes B, C and D are controlled for any VFR flights in there.

Class A is for IFR flights only, if you are VFR, you aren't supposed to be there.

Class G is uncontrolled (but this does not mean ATC is not talking to IFR flight in this airspace).

Unless you have superpowers, there is no way to be absolutely certain of exactly how far away from clouds you actually are, so nobody expects you to be able to do this, nor do they expect you to start taking laser rangefinding readings on every cloud you fly past either. You use your best judgement and if you start getting in a position where you obviously cannot maintain that distance from clouds, that's when you do something about it. Flying through the odd wisp of cloud is fine, as is occasionally getting a bit nearer than 1,000 feet.

The general idea is that you do your level best to adhere to the rules, which is why you check a weather briefing and plan your route accordingly. Soif you fly near one cloud which is 857 feet away from you when you are supposed to be 1,000 feet away from clouds, ATC are not going to scramble jet fighters to go after you. Don't fret about exact distances to clouds, nobody is that good at judging exact distances.

Keep in mind that ATC is not the scary enemy trying to catch you out, they are there to help pilots and they will for the most part give you guidance on where you are supposed to be. But you can help them too by looking at your proposed route and being aware ahead of time what will be expected of you at certain points along your route if it traverses different classes of airspace. So learn the rules for those and note any airspace boundaries on your chart along your proposed route so that you can feel confident that you are not causing a panic on some radar screen somewhere.

However, remember that although ATC is called 'air traffic control', they don't really control aircraft, you do; that's what that big steering wheel in front of you does. So to help demystify different airspace classes, take a look at this and maybe print it out and stick it on the wall next to your computer, or write it down.

 

Thanks! i figured out that 2500 Feet means the airpsace begins there and FL100 means it ends there.
