Detroit Metropolitan Wayne County Airport (DTW) resumed use of the controversial Instrument Landing System Yankee Offset Localizer (ILS-Y) on July 28, 2025, during major runway construction. This move comes despite repeated safety warnings and a formal request from Congresswoman Debbie Dingell to suspend the system’s use.
The ILS-Y is a landing guidance system that helps pilots land planes, but it works differently from standard systems. Instead of guiding planes straight to the runway, the ILS-Y requires pilots to approach at an angle because the localizer antenna is not lined up with the runway. This design has led to frequent signal interruptions, especially when other planes taxi in front of the antenna. These interruptions can cause unstable approaches, forcing pilots to abort landings, which are called “go-arounds.”

On July 29, 2025, Rep. Debbie Dingell sent a letter to FAA Administrator Bryan Bedford, urging the immediate suspension of the ILS-Y at Detroit Metropolitan Wayne County Airport. She cited safety concerns from pilots and air traffic controllers, demanding answers about why the system remains in use. The FAA responded by saying it is reviewing data and safety assessments but has not suspended the system. The agency promised to take further action if needed, stating, “We remain committed to the safety of the flying public.”
Whistleblowers, retired air traffic controllers, and the U.S. Special Counsel have all warned that the ILS-Y may put landing aircraft and passengers at risk. In December 2024 and again in July 2025, Special Counsel Hampton Dellinger sent reports to the President and Congress, stating the system “may create a danger for landing aircraft and the flying public.”
Key stakeholders are divided:
- Rep. Debbie Dingell leads calls for suspension, demanding transparency and safety.
- FAA continues to review the system but has not stopped its use.
- Air traffic controllers and pilots report operational hazards and want the system discontinued.
- Airport management says the system meets federal safety standards with proper safety steps.
The ILS-Y is being used in all weather conditions during the runway construction, except when visibility is too low. This is a temporary measure while the main runway is repaired, expected to last until late August 2025. However, the system’s reactivation has reignited debate over airport landing safety standards. Pilots and airlines may face more go-arounds and unstable approaches, which could cause delays and disrupt flights.
Aviation safety experts argue that the offset localizer design is riskier than standard approaches, especially at busy airports like DTW. Critics say the FAA’s safety steps are not enough to fix the signal problems.
The FAA’s ongoing review could lead to more restrictions, changes, or even a permanent suspension of the ILS-Y. As reported by VisaVerge.com, public and congressional scrutiny is likely to grow if more incidents or whistleblower reports appear.
