Das stimmt nicht ganz, dass ein "Flugplan" (im Sinne von Flugplan aufgeben) nötig ist. SERA meint nämlich mit Flugplan verschiedenes. AustroControl hat das bloss falsch interpretiert und kennt scheinbar Abbreviated Flight Plans gemäss SERA nicht. Bei Auslandflügen muss hingegen schon ein Flugplan aufgegeben werden (am Boden oder mühsam AFIL), sofern das AIP keine Ausnahme erwähnt für bestimmte Länder.
SERA.4001 Submission of a flight plan
Regulation (EU) 2016/1185
(a) Information relative to an intended flight or portion of a flight, to be provided to air traffic services units, shall be in the form of a flight plan. The term ‘flight plan’ is used to mean variously, full information on all items comprised in the flight plan description, covering the whole route of a flight, or limited information required, inter alia, when the purpose is to obtain a clearance for a minor portion of a flight such as to cross an airway, to take off from, or to land at a controlled aerodrome.
(b) A flight plan shall be submitted prior to operating:
(1) any flight or portion thereof to be provided with air traffic control service;
(2) any IFR flight within advisory airspace;
(3) any flight within or into areas, or along routes designated by the competent authority, to facilitate the provision of flight information, alerting and search and rescue services;
(4) any flight within or into areas or along routes designated by the competent authority, to facilitate coordination with appropriate military units or with air traffic services units in adjacent States in order to avoid the possible need for interception for the purpose of identification;
(5) any flight across international borders, unless otherwise prescribed by the States concerned;
(6) any flight planned to operate at night, if leaving the vicinity of an aerodrome.
(c) A flight plan shall be submitted, before departure, to an air traffic services reporting office or, during flight, transmitted to the appropriate air traffic services unit or air-ground control radio station, unless arrangements have been made for submission of repetitive flight plans.
(d) Unless a shorter period of time has been prescribed by the competent authority for domestic VFR flights, a flight plan for any flight planned to operate across international borders or to be provided with air traffic control service or air traffic advisory service shall be submitted at least 60 minutes before departure, or, if submitted during flight, at a time which will ensure its receipt by the appropriate ATS unit at least 10 minutes before the aircraft is estimated to reach:
(1) the intended point of entry into a control area or advisory area; or
(2) the point of crossing an airway or advisory route.

GENERAL
(a) A flight plan may cover only part of a flight, as necessary, to describe that portion of the flight or those manoeuvres which are subject to air traffic control.
(b) The term ‘submit a flight plan’ refers to the action by the pilot or the operator to provide ATS with flight plan information. The term ‘filed flight plan’ refers to the flight plan as received and accepted by ATS whereas ‘transmit a flight plan’ refers to the action by a pilot to submit the flight plan, or submit abbreviated flight plan by radiotelephony to the ATS unit concerned.

ABBREVIATED FLIGHT PLAN
An abbreviated flight plan transmitted in the air by radiotelephony for the crossing of controlled airspace, or any other areas or routes designated by the competent authority, normally contains, as a minimum: call sign, type of aircraft, point of entry, point of exit and level. Additional elements may be required by the competent authority.
