What radio frequency do airports use?

What radio frequency do airports use?

CTAF Frequencies The Common Traffic Advisory Frequency (CTAF) or Unicom frequencies are typically used at nontowered airports. The most common are 122.7, 122.8, 122.9, 123.0. 123.050 MHz with 122.950 being the usual CTAF frequency of choice for airports with a tower.

Why do runways cross each other?

Description. A Runway Crossing Incursion is considered here to occur when an aircraft or vehicle which requires to cross one or more active runways, in order to complete an intended aerodrome ground movement, comes into actual or potential conflict with an aircraft using the same runway for landing or take off.

Why do airports have runways in different directions?

Airports change runways direction because taking off and landing into the wind can be done at lower speeds and in less time. Simply put, when taking off, a headwind will create more lift. When landing, winds at your nose will also act as a speed break by creating drag against the airframe to slow the aircraft down.

On which frequency will pilots communicate to each other at a non towered airport?

126.7 MHz
The most common CTAF frequency is 126.7 MHz at non-towered aerodromes, except for when two CTAF airports are near each other. Aerodromes using CTAF outside tower hours typically nominate a frequency that is used during tower hours.

How do I find flight frequencies?

The Flight Service frequencies are listed in a box above certain VOR stations. The most common frequencies are 122.2, 122.4, or 122.6. Also, most GPS (or iPad apps like ForeFlight) have a listing of the nearest Flight Service frequencies.

What direction do runways face?

Runway directions are largely chosen both for geographic land features of the site of the airport as well as the average local wind directions. As most winds blow from West to east in the continental United States, most runways will be oriented approximately in that direction.

How do you land on a non towered airport?

Non towered airports traffic patterns are always entered at pattern altitude. How you enter the pattern depends upon the direction of arrival. The preferred method for entering from the downwind leg side of the pattern is to approach the pattern on a course 45° to the downwind leg and join the pattern at midfield.

When do you need to do multiple runway crossings?

At those airports where the taxi distance between runway centerlines is 1,300 feet or less, multiple runway crossings may be issued with a single clearance. The air traffic manager must submit a request to the appropriate Service Area Director of Air Traffic Operations and receive approval before authorizing multiple runway crossings.

What do the lights at the end of the runway mean?

The lights marking the ends of the runway emit red light toward the runway to indicate the end of runway to a departing aircraft and emit green outward from the runway end to indicate the threshold to landing aircraft. Runway Centerline Lighting System (RCLS).

When to issue unconditional instructions on a runway?

Do not issue unconditional instructions when authorizing movement on a runway/taxiway for the purpose of airfield checks or other airport operations. Instructions must ensure positive control with specific instructions to proceed on a runway or movement area, and as necessary, hold short instructions.

What do pilots need to know about runway procedures?

The authority exercising operational control of such aircraft ensures that all pilots are thoroughly familiar with these procedures, including the usable runway length from the applicable intersection. Some airports publish “declared distances” for a particular runway.
