Welcome to Aviation Stack Exchange

Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about aviation.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Do ATC displays show the target altitude that the pilot has set in the autopilot?

up vote 14 down vote favorite

When cleared to climb/descend to a level, the pilot enters that level in an altitude preset window, allowing the autopilot to climb/descend and level off at that level. Is this level, preset by the pilot, visible on an ATC radar screen?

Yes, our radar is indeed capable to display data of the Mode S Enhanced Surveillance Transponder like Selected altitude, IAS, Mach Number, Heading and more. After issuing a climb/descend clearance and entering it into the sytem it would also warn us if the selected altitude is different from the cleared level.

No. That information is contained within the automatic flight control system. All altitude reporting to ATC comes from a radar transponder with an altitude reporting capability.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Specific issues with aviation
  • Real problems or questions that you’ve encountered

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to aviation
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

Nice. Info from Eurocontrol, for further reading: eurocontrol.int/articles/mode-s-operational-overview - I hadn't heard of this, and I'm not sure the US is set up to use EHS. Is this just limited to some parts of EU? - egid Apr 13 at 21:26
