Sustainable Aviation Fuel MCQ

Question 1

With reference to the U.S. SAF Initiative, consider the following statements:
1. It is an interagency effort of the Department of Energy, Department of Transportation and Department of Agriculture.
2. It seeks to expand sustainable aviation fuel production and use through a government-wide memorandum of understanding.
3. It is led jointly by the Environmental Protection Agency, Federal Aviation Administration and Department of Commerce.
Which of the statements given above are correct?

Accepted Answer

Statement 1 is correct because the cited fact identifies DOE, DOT and USDA as the interagency partners. Statement 2 is correct because the initiative expands SAF production and use through a government-wide memorandum of understanding. Statement 3 is wrong because the listed EPA, FAA and Commerce grouping is not the interagency set named in the fact.

Question 2

Assertion (A): India decided not to participate in the voluntary pilot and first phases of CORSIA.
Reason (R): Offsetting requirements for Indian carriers under CORSIA start from 2024.
Choose the correct answer.

Accepted Answer

The Assertion is true because India decided not to join CORSIA's voluntary pilot and first phases. The Reason is false because the offsetting requirements for Indian carriers start from 2027, not from 2024. Therefore the explanation based on a 2024 start date is not valid.

Question 3

With reference to Sustainable Aviation Fuel (SAF) in India, consider the following statements: 1. SAF is a renewable aviation-grade hydrocarbon fuel chemically similar to ATF and fully compatible with existing aircraft engines. 2. The Bureau of Indian Standards specification IS 17081 specifically covers SAF blended with traditional Aviation Turbine Fuel. 3. The mandatory phase of CORSIA, the global market-based measure for international aviation, begins in 2027. Which of the statements given above are correct?

Accepted Answer

All three statements are correct as per the PIB release of April 23, 2026 and BIS standards. SAF is a drop-in renewable hydrocarbon fuel chemically similar to ATF, IS 17081 specifically covers SAF blended with conventional ATF (IS 1571 covers petroleum-based ATF and co-processed SAF), and the mandatory phase of CORSIA implemented by ICAO begins in 2027 requiring offsetting of emissions above the baseline.

Question 4

Match the ReFuelEU Aviation SAF requirement milestones with their mandated shares at EU airports.

List I
1. From 2025
2. From 2050

List II
X. 2% of aviation fuel at EU airports
Y. 70% at all EU airports
Z. 10% of aviation fuel at EU airports
W. 35% at all EU airports

Select the correct matching.

Accepted Answer

The correct matching is from 2025 with 2% of aviation fuel at EU airports, and from 2050 with 70% at all EU airports. The 10% share is a near-miss from another mandate trajectory, not this ReFuelEU Aviation SAF milestone. The 35% figure relates to synthetic aviation fuel from 2050, not the overall SAF share tested here.

Question 5

As per India's indicative Sustainable Aviation Fuel blending targets in Aviation Turbine Fuel for international flights, which sequence is correct?

Accepted Answer

The cited PIB release gives the indicative blending targets for international flights as 1% in 2027, 2% in 2028 and 5% in 2030. The sequences beginning in 2026, jumping to 10% by 2030, or starting at 5% in 2027 do not match the stated target path.
