There is no FAA requirement that I know of, If there were, how would
students manage cross-country practice? A club, commercial operation, or
insurance company may have more stringent requirements and an instructor may
put any limitation in a student's logbook (61.89 (a) (8). Below is the
operative section of part 61 concerning solo student flight:

61.87
L) Limitations on student pilots operating an aircraft in solo flight. A
student pilot may not operate an aircraft in solo flight unless that student
pilot has received:
(1) An endorsement from an authorized instructor on his or her student pilot
certificate for the specific make and model aircraft to be flown; and

(2) An endorsement in the student's logbook for the specific make and model
aircraft to be flown by an authorized instructor, who gave the training
within the 90 days preceding the date of the flight.

(m) Limitations on student pilots operating an aircraft in solo flight at
night. A student pilot may not operate an aircraft in solo flight at night
unless that student pilot has received:

(1) Flight training at night on night flying procedures that includes
takeoffs, approaches, landings, and go-arounds at night at the airport where
the solo flight will be conducted;

(2) Navigation training at night in the vicinity of the airport where the
solo flight will be conducted; and

(3) An endorsement in the student's logbook for the specific make and model
aircraft to be flown for night solo flight by an authorized instructor who
gave the training within the 90-day period preceding the date of the flight.

(n) Limitations on flight instructors authorizing solo flight. (1) No
instructor may authorize a student pilot to perform a solo flight unless
that instructor has --

(i) Given that student pilot training in the make and model of aircraft or a
similar make and model of aircraft in which the solo flight is to be flown;

(ii) Determined the student pilot is proficient in the maneuvers and
procedures prescribed in this section;

(iii) Determined the student pilot is proficient in the make and model of
aircraft to be flown;

(iv) Ensured that the student pilot's certificate has been endorsed by an
instructor authorized to provide flight training for the specific make and
model aircraft to be flown; and

(v) Endorsed the student pilot's logbook for the specific make and model
aircraft to be flown, and that endorsement remains current for solo flight
privileges, provided an authorized instructor updates the student's logbook
every 90 days thereafter.

(2) The flight training required by this section must be given by an
instructor authorized to provide flight training who is appropriately rated
and current.
