What is the minimum distance between two civil airplanes parked in a hangar?

When parking two airplanes in the hangar, what is minimum safe distance between them?

• Welcome to aviation.SE! Are you asking about airliners, or any civil aircraft? If you look in a shared hangar at a GA airport, you'll often see aircraft packed in with only a few centimeters between them (and between them and the walls). Commented Aug 30, 2015 at 23:37
• Minimum safe distance == "not touching" Commented Aug 31, 2015 at 1:33
• Yaa , for airlines. Is there any besic rules to them on hanger.

• @casey you should have linked this video with your "not touching" :D Commented Aug 31, 2015 at 8:09
• As a student pilot, when I completed my 3-stop, long solo flight, I returned to the FBO after hours. The hardest part of the entire flight was parking my plane back in its spot, by myself, with less than 2 inches of room on each wing. If it fits, it fits. Commented Aug 14, 2017 at 17:01

If you look at some civil-aircraft hangars, you will see that the planes are almost touching each other, as you can see here:

The planes are so close to each other to fit a maximum amount of planes into a hangar.

There are different types of hangars. Some are built just to store aircraft when they aren't used, some are built for aircraft-maintenance-operations and can even contain robots. Hangars can be simple buildings with a big and open space or they can be very complex facilities.

You can find the minimum separation distances between aircraft and minimum distances between the aircraft and other obstructions here

Take a look at this table from this document (page 30):

As you can see, the minimum distance between the wings from two parked aircraft is not always the same.

Dimensions vary for different models and configurations of aircraft.

If you want to find out the min. distance of an A380, you need to take a look at the documents provided by Airbus.

No, there is no basic rule. The safe distance is determined by the aircraft-type, configuration and the hangar (owner).

If the airliners are stored in the hangar, they can be pretty close to each other. However, maintenance of a big airliners takes up a lot of space:

• @JeffreyBosboom I'm sorry, I misspelled "robot". " roboter" is german for "robots". Commented Aug 31, 2015 at 17:20
• When stacking planes vertically, make at least sure an deflated tire will not lead to a contact. It is prudent to leave a little more space than "not touching". Commented Feb 4, 2016 at 14:19
• @jklingler e.g. by placing a high-wing aircraft close to a low-wing aircraft so that the wings of the former overhang the latter, or a small aircraft under the wing of a much larger one. Commented Feb 4, 2016 at 15:28
• @DanHulme and here I was thinking hanging them from the ceiling ;) Commented Aug 14, 2017 at 8:52

"Don't hit the other planes. Don't hit the walls. Don't hit anything else in the hangar." - that's the minimum safe distance.

There may be other requirements (e.g. by fire code: the number of aircraft stored in a hangar may be restricted by the amount of fuel each aircraft holds, and by the hangar's fire suppression capabilities).

Similarly in a hangar where active maintenance is happening the space between each aircraft may be larger to allow maintenance personnel access to each aircraft.

• Sometimes the wings will overlap, with a high wing plane's wing over those of a low wing plane. Commented Sep 1, 2015 at 0:49
• and with gliders, you'll see them all with one wing on the ground and one wing in the air, all tilted the same way, with sandbags on the low wing.
