What is CTAF? Explain CTAF procedures at your training airports. CTAF is common traffic advisory frequency. It is used when there is no controlled towered at the airport and it is the radio frequency to allow pilots to communicate and to locate themselves and what they are intended to do.

Simply so, what does Ctaf stand for?

Common traffic advisory frequency

Secondly, how do you leave a traffic pattern? If departing the traffic pattern, continue straight out, or exit with a 45-degree turn (to the left when in a left-hand traffic pattern; to the right when in a right-hand traffic pattern) beyond the departure end of the runway, after reaching pattern altitude.

Similarly, you may ask, what is Safetycom?

The CAA has unveiled the details long awaited SAFETYCOM which is intended to be similar to the widely used UNICOM in the USA. Assigned the frequency 135.475 MHz SAFETYCOM can be used throughout the UK by aircraft operating in the vicinity of an aerodrome or landing site that does not have an air to ground frequency.

What is a Class D airspace?

Class D airspace is for IFR and VFR flying. An ATC clearance is needed and compliance with ATC instructions is mandatory. Control areas around aerodromes are typically class D and a speed limit of 250 knots applies if the aircraft is below FL 100 (10,000 feet).

What information does ATIS provide?

ATIS (Automatic Terminal Information Service) is a recording that some airports broadcast in order to reduce frequency congestion. Current weather information, active runway information, NOTAMs, and other useful pieces of information are included in the ATIS.

What is the difference between AWOS and ASOS?

Some specific differences are a difference in wind observations. AWOS broadcasts true wind direction, while ASOS converts surface winds to magnetic direction. In addition precipitation type identification and thunderstorm reporting are different between the two.

What is the difference between ATIS AWOS and ASOS?

ATIS is usually only found at towered airports, and is a recording giving the winds and pertinent NOTAMs and other information pilots may need about the airport. ASOS is a automated machine owned by the National Weather Service that provides current weather information.

What does AWOS 3 mean?

AWOS III: all AWOS II parameters, plus sky condition (in oktas), cloud ceiling height (in feet), and liquid precipitation. accumulation (in inches). AWOS III P: all AWOS III parameters, plus precipitation type (rain, snow and sometimes drizzle) identification.

What is Depcom?


DEPCOM - Helicopters at airfields with no ground radio facilities. 135.475. SAFETYCOM - Aircraft at airfields with no ground radio facilities.

What is Depcom frequency?

The frequency assigned is 122.950 MHz and shall be known as 'DEPCOM'.

What frequencies do aircraft use?

Common Civilian Frequencies
In the US the civil aircraft communications band (118-137 MHz) generally uses 25 kHz spaced channels. As of 2010 aeronautical enroute and flight test stations may use 8.33 kHz spaced channels in the 121.4-123.6, 128.825-132.0 and 136.5-136.875 MHz ranges.

What is 8.33 kHz spacing?

By reducing the channel spacing between consecutive transmit frequencies in the aeronautical VHF bands, the 8.33 kHz channel spacing adds two additional channels for every 25 kHz channel. For an 8.33 kHz channel the transmit frequencies will have at least four digits after the decimal.

Why do aircraft use AM radio?

Aviation voice radios use VHF AM. AM is used so that multiple stations on the same channel can be received. (Use of FM would result in stronger stations blocking out reception of weaker stations due to FM's capture effect).

What frequency is ATC?


All ATC communications are between 118.0 and 137.0 MHz. If you think you're given a frequency above or below those numbers, there is a mistake. FSS frequencies are all in the 122 and 123 MHz series; for example, 122.25, 122.3, 122.35, 122.45, 122.55, 122.6, 122.65, and 123.65 MHz.

What is the difference between a contact approach and a visual approach?

Well, they're both instrument approaches, but the main differences are that visual approaches are published (as in, they're found on IAP “plates”), whereas contact approaches aren't. A contact approach gives you the leeway to “find your own path” to the airport. You have to ask for them… ATC can't issue them.

What are the requirements for a contact approach?

What are the requirements for a contact approach to an airport that has an approved IAP, if the pilot is on an instrument flight plan and clear of clouds? A) The pilot must request the approach, have at least 1 mile visibility, and be reasonably sure of remaining clear of clouds.

How do you pronounce altitude ATC?

SAY ALTITUDE—Used by ATC to ascertain an aircraft's specific altitude/flight level. When the aircraft is climbing or descending, the pilot should state the indicated altitude rounded to the nearest 100 feet. SAY HEADING—Used by ATC to request an aircraft heading.

How do you make a radio call?

Follow these easy steps to make a call.
  1. First, listen to ensure the channel is clear for you.
  2. Press the PTT (Push-To-Talk) button.
  3. After 2 seconds: Say "recipient's call sign" twice. followed by "THIS IS" and "your call sign".
  4. Once the person replies, convey your message.

Can ATC offer you a contact approach?


If all those things are true then you can request a contact approach (ATC can't offer it). But ATC has requirements to meet too: Controllers may authorize a contact approach provided: The contact approach is specifically requested by the pilot.

Is a visual approach an instrument approach?

A visual approach is an ATC authorization for an aircraft on an IFR flight plan to proceed visually and clear of clouds to the airport of intended landing. A visual approach is not a standard instrument approach procedure and has no missed approach segment.

What are the legs of a traffic pattern?

Patterns are typically rectangular in basic shape, and include the runway along one long side of the rectangle. Each leg of the pattern has a particular name: Upwind leg. A flight path parallel to and in the direction of the landing runway.
