There are some MMs still in use, but no MMs are being installed at new ILS sites by the FAA; and An IM, where installed, indicates the point at which an aircraft is at decision height on the glide path during a Category II ILS approach.
What indications will a pilot receive where an IM is installed on a front course ILS approach? Six dots per second and a flashing white light. increased if the groundspeed is increased. groundspeed. Approximately what height is the glide slope centerline at the MM of a typical ILS?
What indication should a pilot receiver when a VOR station is undergoing maintenance and may be considered unreliable? No coded identification, but possible navigation indications. A particular VOR station is undergoing routine maintenance. This is evidence by removal of the identification feature.
How does a pilot determine if DME is available on an ILS/LOC? IAP indicate DME/TACAN channel in LOC frequency box. Which of the following statements is true regarding Parallel ILS approaches? Parallel ILS approaches provide aircraft a minimum of 1 1/2 miles radar separation between successive aircraft on the adjacent localizer course.
Immediately after passing the final approach fix inbound during an ILS approach in IFR conditions, the glide slope warning flag appears. The pilot is permitted to continue the approach and descend to the localizer MDA. Which substitution is appropriate during an ILS approach?
Category II ILS approach systems may include a third marker beacon called the inner marker (IM), although these are becoming less common. The inner marker, where installed, is located on the front course between the MM and the landing threshold.
The ILS provides the lateral and vertical guidance necessary to fly a precision approach. When all components of the ILS system are available, including the approved approach procedure, the pilot may execute a precision approach.
Outer Marker: Identifies glideslope intercept or the Final Approach Fix (light flashes blue) Middle Marker: Identifies decision height (light flashes amber) Inner Marker: Identifies decision height for a CAT II ILS (light flashes white - we'll talk about what CAT II means below)
ILS stands for Instrument Landing System which is a radio navigation aid that directs the aircraft towards the runway for landing. It shows the pilots if they are at the correct height for the approach and how far left or right the aeroplane is from the runway center line.
Pilots don't (usually) do autoland, i.e. having autopilot follow the ILS all the way down to the ground, in good weather.
Definition. Instrument Landing System (ILS) is defined as a precision runway approach aid based on two radio beams which together provide pilots with both vertical and horizontal guidance during an approach to land.

What are the two main components of an ILS on the ground? Explanation: ILS system basically comprises a localiser transmitter and a glide slope transmitter located by the airport runway together with two or three radio marker beacons located at set distances along the approach to the runway.

ILS information received from the ILS signal will be displayed in magenta to the left of the heading reference line and scale. It shows the ILS identification, ILS frequency and the DME distance, if the ILS has a DME.
This is displayed in magenta on the heading reference line and scale when the crew has selected an ILS frequency and course, and the LS button on the EFIS in on.
This appears to the right of the localiser deviation scale, and flashes amber when the approach mode is armed and the LS display is not selected.
