What does RVR 5 mean?
RVR 5 is now the lowest authorized take-off minimum based upon outside visual references. • High intensity runway lighting (HIRL) is required for take-off operations less than RVR 10. The following requirements and restrictions apply to the use of RVR values below RVR 16: a.
Can you call ATIS?
Phone numbers are often available for the ATIS, too. Call the AWOS or ATIS number before you finish the preflight inspection—or even before you leave the comfort of the FBO. An ATIS is typically updated at 50 to 55 minutes after the hour, except when conditions are changing rapidly.

ATIS contains current, routine information to arriving and departing aircraft as well as weather reports derived from human data collection that is updated hourly or upon pertinent data changes. AWOS and ASOS are automated and provide continuous real-time weather observations.
What is UNICOM and CTAF?
UNICOM is a licensed non-government base station that provides air-to-ground and ground-to-air communication, and may also serve as a CTAF when in operation. MULTICOM is a frequency allocation without a physical base station that is reserved as a CTAF for airports without other facilities.
What is decision height?
Definition. The Decision Altitude (DA) or Decision Height (DH) is a specified altitude or height in the Precision Approach or approach with vertical guidance at which a Missed Approach must be initiated if the required visual reference to continue the approach has not been established. (
What is controlling RVR?
— Controlling RVR means the reported values of one or more RVR reporting locations (touchdown, mid-point and stop-end) used to determine whether operating minima are or are not met. Where RVR is used, the controlling RVR is the touchdown RVR, unless otherwise specified by State criteria.
What frequency is ATIS?
The second radio is assigned clearance, ground, weather (ATIS, ASOS), and flight service duties–remember to monitor the emergency frequency (121.5 MHz) when you’re not using the second radio.
