When can a pilot deviate from ATC instruction?

When can a pilot deviate from ATC instruction?

(a) When an ATC clearance has been obtained, no pilot in command may deviate from that clearance unless an amended clearance is obtained, an emergency exists, or the deviation is in response to a traffic alert and collision avoidance system resolution advisory.

How does a pilot communicate with ATC?

The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.

When should you contact ATC approach?

A contact approach will only be issued if the aircraft is operating clear of clouds with at least 1-mile of flight visibility, with a reasonable expectation of continuing to the destination airport under those conditions.

When should the approach controller give the pilot a frequency change to the tower?

During busy periods the traffic controllers pack the approaching aircraft so that there are only about 5 km between them. When an aircraft is about 15 km from the runway, the traffic controller requests the pilot to change radio frequency and contact tower control.

What Preflight action must a pilot perform prior to any flight?

Initial Preflight Actions: Pilots in command shall, before beginning a flight, become familiar with all available information concerning that flight.

What does a pilot say before taking off?

There is an announcement like: “Flight attendants, prepare for take-off please.” “Cabin crew, please take your seats for take-off.” Within a minute after take-off, an announcement might be made reminding passengers to keep their seat belts fastened.

What ATC facility should the pilot contact to receive a special VFR departure?

What ATC facility should the pilot contact to receive a special VFR departure clearance in Class D airspace? Air Traffic Control Tower.

When should I switch to tower frequency?

this only applies when you’ve taxied to the hold-short with Ground. If Ground tells you to switch earlier, do it. If you want to switch earlier, request it. This seems to suggest that it is OK to switch to tower once you have completed the runup and are ready to takeoff at least in the US.

Why do planes circle after takeoff?

Answer: The maneuver you describe is usually either a 360 degree turn issued by the air traffic controller to increase spacing between your flight and another airplane, or it was one turn in a holding pattern. The one turn in a holding can occur when the expected hold time is reduced, requiring only a single turn.

How does a pilot communicate with an ATC?

The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.

What’s the active VHF-L frequency on an ATC?

Firstly, the active VHF-L frequency changes to 133.65 as requested. However, instead of the previous frequency (123.45 in the photo) disappearing from view, it flips across to the SBY column. This is particularly useful in the event that we are unable to make contact with the new ATC unit — a fairly common event.

How do I Change my ATC to 133.65 MHz?

For example, if ATC (on VHF-L) asks us to change to another ATC frequency on 133.65 MHz, we’d type “13365” on the number keys and press the first key-select button on the left-hand side. When we do this, two things happen. Firstly, the active VHF-L frequency changes to 133.65 as requested.

Is it important to acknowledge radio contact with ATC?

It is essential, therefore, that pilots acknowledge each radio communication with ATC by using the appropriate aircraft call sign. Brevity is important, and contacts should be kept as brief as possible, but controllers must know what you want to do before they can properly carry out their control duties.
