In realty...
that's almost every flight you'll fly ! but in practice you would not log all of them. Are you shure it isn't more like 30. It can't be considered cross country if you don't cross any ??
This is what I found regarding the FAA requirements for X-C flight:
Cross-Country Time
The basic definitions of cross-country time are found in 14 CFR Part 61.1 (b)(3). A cross-country flight is any flight that involves a landing at another airport and involves navigation. This may be relevant to you when you are looking to qualify under Part 135 pilot requirements, since there this basic definition of cross-country is used. However, there is a difference in this basic definition and the requirements for cross-country flight to count as the appropriate aeronautical experience for a certificate or rating.
In essence:
To meet the requirements for a Private or Commercial certificate or for an Instrument rating or to "exercise the privileges of a Recreational" certificate the flight must include a LANDING at a point MORE than 50NM from the point of original departure.
For an ATP certificate the requirement is for a FLIGHT (not a landing) more than 50NM straight line distance from the point of departure.
Otherwise any landing at any other airport counts as cross-country time. This is generally important for people looking to meet the 14 CFR Part 135 PIC requirements.
