ETOPS-kravet är ungefär samma för alla flygplan oberoende av användningen så länge som det är under 121 eller 135, enligt FAA InFO 07004, Nya ETOPS-förordningar :
The new ETOPS rules are now applicable to:
Part 121
• All two-engine airplanes more than 60 minutes flying time from an adequate airport (at a one-engine-inoperative cruise speed under standard conditions in still air).
• All passenger-carrying airplanes with more than two engines and more than 180 minutes flying time from an adequate airport (at a one-engine-inoperative cruise speed under standard conditions in still air).
Part 135
• All multi-engine turbine-engine powered airplanes (other than all-cargo operations with airplanes having more than two engines) more than 180 minutes flying time (limited to 240 minutes flying time) from an airport meeting the requirements of part 135, §§ 135.385 or 135.393 and 135.219 at an approved one-engine-inoperative cruise speed under standard conditions in still air.
Vad gäller skillnader är ETOPS avstår endast i ett fall :
The FAA ... however agree that for airplanes with more than two engines, passenger carrying operations may be excluded from the ETOPS maintenance program requirements and that all-cargo operations may be excluded from all ETOPS requirements.
Definitionen av ETOPS i samma dokument täcker alla flygplan, med undantag för fyra begagnade lastbilar:
Extended Operations (ETOPS) means an airplane flight operation other than an all-cargo operation in an airplane with more than two engines during which a portion of the flight is conducted beyond a time threshold identified in part 121 or part 135 of this chapter that is determined using an approved one-engine-inoperative cruise speed under standard atmospheric conditions in still air.
När det gäller icke-inkomster flygningar betraktas de vanligtvis under del 91, så ETOPS-reglerna gäller inte. Det är dock bättre att planera en ETOPS-väg för säkerhetshänsyn (och för att hålla försäkringsbolagen lyckliga).
