PRECISION CAT I ILS APPROACH AND DEPARTURE PROCEDURES WITH REDUCED OPERATING MINIMA BY ADDITIONAL USE OF THE HEAD-UP DISPLAY (HUD)

This Aeronautical Information Circular (AIC) gives the requirements for the establishment of Category I ILS Authorization Required approach procedure charts (CAT I ILS AR) and Low Visibility Takeoff (LVTO) operations. The CAT I ILS AR procedures described in this AIC, destined to Operators specifically approved by the competent unit, will use a minimum of 450 m Runway Visual Range (RVR) and 150 ft Decision Height (DH), determined by the Radar Altimeter Setting Height (RA), being required by the Pilot in Control the use of the Head-up Display (HUD) up to the DA/DH. Low Visibility Takeoff (LVTO) operations addressed in this AIC, also aimed at Operators specifically approved by the competent unit, can be performed with minimum RVR values which could reach 75 m, at least, according to specific criteria, and it is not required that the landing and takeoff runways dispose of touchdown zone lights or runway centerline lights since the Pilot in control of the aircraft uses the HUD. The requirements for publication of relevant information in the mentioned CAT I ILS AR and LVTO charts are also presented in this AIC.
