Stoppflug

[Richard T. Eger]

Dear All,

Not one of my dictionaries nor online translators gives me what I think would be the real meaning of "Stoppflug". I was thinking it might mean static test, but a line in the report suggests otherwise:

"Geschwindigkeit in 0 m = 428 km/h."

Can anyone help?

Regards,
Richard

I got 'Stop Flying' and 'Stop Flight'.

HTH
Good luck...

Another meaning of "stoppen" is to time with a stopwatch.

My military dictionary gives "Stoppzeit" as time interval/time difference/time lag. Elsewhere it is given as deceleration or stopping time.

In my opinion "Stoppflug" method refers to the flight time measured between two gates (measure points) on specific distance. From dividing time/distance data the ground speed is given (horizontal speed of an aircraft relative to the ground). This is more simple and accurate method on low altitude (for example sea level flight), than reading speed directly from airspeed indicator on the plane's cockpit and making corrections due to various conditions (wind speed and direction, atmospheric pressure etc.).

I, also, got "stop flight", but it just didn't make any sense to me. I think the idea that the airspeed was timed from the ground makes sense, but I'm wondering if anyone out there more intimately knowledgeable in this area can add to our understanding.

Regards,
Richard

Not in the Manual of German Air Force Terminology, so apparently it was not a widely used term.

Take off and go? To practise landing and take off

Definitely not. This term was used on different test charts, and it could be not commonly known for average pilot. So the measure was possible in well equipped on test centers. For example from Bf 109G-5 test chart:

"Geschwindigkeit in 0 m.
Die Geschwindigkeit am Boden wurde durch einem Stoppflug über der Stoppstrecke mit Kampfleistung...."

"Speed at 0 m level.
The speed at sea level was accomplished by timed flight (Stoppflug) over the test course (Stoppstrecke) at combat power..."

That's mean the test run was made on prepared route/track.

Spot on, Sailor. Well explained.
The term "stoppen" is derived from "Stoppuhr" (stop watch) and thus is a loan word from the english language

Thanks net sailor, that seems to the answer.
