What equipment is needed for ILS?

Compass locator; or. Precision Approach Radar (PAR); or. Airport Surveillance Radar (ASR); or. DME, Very-High Frequency Omni-directional Range (VOR) radial intersections or Nondirectional Beacon (NDB) fixes authorized in the Standard Instrument Approach Procedure; or.

How expensive is ILS?

The annual preventative maintenance cost for a single ILS can run as high as $25,000 and averages about $19,000 to $20,000. GPS landing systems promise lower maintenance cost, which is one reason why FAA hopes to replace ILS.

Is ILS obsolete?

The FAA said in early 2019 that ILS approaches could even be discontinued this year. But the longer it takes the FAA to make its decision, publish it, evaluate comments and respond, the later cutting can begin.

Is MLS better than ILS?

MLS has a number of operational advantages over ILS, including a wider selection of channels to avoid interference with nearby installations, excellent performance in all weather, a small “footprint” at the airports, and wide vertical and horizontal “capture” angles that allowed approaches from wider areas around the …

Will VOR become obsolete?

The VORs will be closed in two phases: one running through 2020, and the second from 2021 to 2025. “The FAA remains committed to the plan to retain an optimized network of VOR NAVAIDs,” the agency said.

Can I use GPS instead of DME?

GPS can be used in lieu of DME and ADF on all localizer-type approaches as well as VOR/DME approaches, including when charted NDB or DME transmitters are temporarily out of service. It also clarifies that IFR GPS satisfies the requirement for DME at and above Flight Level 240 specified in FAR 91.205(e).

Can you fly an ILS with GPS?

You can still fly IFR in the U.S. without an IFR-approved GNSS (i.e., GPS), but being “slant G” (/G in the soon-to-be obsolete FAA domestic flight plan format) increasingly offers advantages, even if you fly only conventional procedures based on ground navaids.
