A layout of an instrument runway.
A runway equipped with visual and electronic navigational aids for which a precision or a non-precision approach with straight-in landing minimums has been approved. There may be more than one instrument runway on an airfield. The various types of instrument runways are the:
i. Non-Precision approach runway. An instrument runway served by visual aids and a nonvisual aid providing at least directional guidance adequate for a straight-in approach.
ii. Precision approach runway category I. An instrument runway served by an ILS (instrument landing system) and/or an MLS (microwave landing system) and visual aids intended for operations with a decision height not lower than 200 ft (60 m) and a runway visual range of the order of 800 m (2600 ft). (When RVR is not available, 0.5 statute miles ground visibility is substituted.) Rotorcraft visibility limits may be half those published for airplanes.
iii. Precision approach runway category II. An instrument runway served by an ILS and/or an MLS and visual aids intended for operation with a decision height lower than 200 ft (60 m) but not lower than 100 ft (30 m) and a runway visual range not less than 400 m (1200 ft). Rotorcraft visibility limits may be lower than those published for airplanes.
iv. Precision approach runway category III. An instrument runway served by an ILS to and along the surface of the runway and intended for operations down to an RVR (runway visual range) of the order of 200 m (600 ft) (no decision height is applicable), using visual aids during the final phase of landing; or intended for operations down to an RVR of the order of 50 m (150 ft) (no decision height is applicable), using visual aids for taxiing; or intended for operations without reliance on visual reference for landing or taxiing. The visual aids need not necessarily be matched to the scale of the nonvisual aids provided. The criterion for the selection of visual aids is the condition under which operations are intended to be conducted.

Tenders are invited for the irish aviation authority (iaa) requires replacement of it~s existing instrument runway visual range (irvr) systems at dublin, shannon and cork airports.
The runway has basic, visual markings; straight-in minimums require at least non-precision instrument runway markings.
There was no further damage to the aircraft or to Balad's only instrument runway. Capt Winters' and A1C Gillespie's demonstration of remarkable skill and top-notch crew resource management saved three of the Air Force's and CENTCOM's most requested theater assets in the course of a single month--making them more than deserving of this award for which they are nominated.
the iaa intends replacing the existing instrument runway visual range (irvr) systems at dublin, cork and shannon airports and installing an irvr on the new parallel runway.
It means that you'll need to line up perfectly on centerline when you may only be able to see a few stripes (on an FAA-standard instrument runway, they're 120 feet long and 80 feet apart).
A VFR aircraft assigned a shorter runway parallel to a longer instrument runway with the instructions to "fly runway heading" could drift into the departure path of the longer instrument runway.
When the primary instrument runway (06R/24L) has to be closed for snow removal, careful co-ordination is maintained between Airport Operations, Airfield Maintenance and ATC.
implement RNP Approaches (LNAV/VNAV) and Localiser Performance with Vertical guidance on all instrument runway ends of the civil aerodromes located within the Belgian part of the Brussels Flight Information Region outside the Brussels TMA (Charleroi, Lige, Ostend).
Fog detectors called Instrument Runway Visual Range (IRVR) measure fog on runways and indicate the visual range.
In addition to the reduced ongoing costs to obtain weather observations, many AWOS/ASOS sensors (e.g., visibility) can be located near the touchdown zone of a primary instrument runway. By contrast, a human observer most likely would be some distance from the touchdown zone.
If I had not seen the one white position light, among all the other lights associated with this instrument runway, we would have collided at about the time we touched down.
