Requests and clearances...

Thanks to keyboard inputs you can talk to the ATC.

Affectations...
Clic Settings/Requests

1. Select the line in the list you want to change then press the key you want to use for the given request. The key you pressed must appear in the Key column.
2. WARNING!: you must use keys that are not used for any other command in X-Plane!  If not, Assume that "A" key is requesting for take-off clearance in EasyATC and is toggling gears, when you will press this key after take-off to move up gears, the pilot's voice will request for a take-off clearance!
3. Clic Save button when all affectations are done

How to request...

1. Press the key of the request
2. The ATC menu item of EasyATC is turning blue
• This means the ATC and the AIs let you talk
• I added this option for people like me who want to request by speaking and not only by pressing a key and using the pilot's synthesized voice.
3. Then, once you have spoken your request, press the Return key to actually send the request to EasyATC and get an answer... I hope...

Requests...
Awake ATC
The pilot simply announce its situation in short way. This is inspired by what it seems to be usually said in IFR when contacting the first time an approach controller. See this video.

Altitude up or down
This request consists in asking for a given number of feets to climb or descend. The pilot asks for the next waypoint expected altitude more or less the ALTITUDE_CHANGE_REQUEST_FEET value in the constants you can edit as you wish (1000 ft by default).
So, assuming you fly at 10,000 ft, and the next waypoint Altitude is 12,000 ft if you want to fly at 14,000 ft, you have to request twice: a first time to obtain 13,000 ft and a second one to be cleared o 14,000 ft.
This is not very user friendly and will be improved one day, but asking for altitude change is not something you ask every 5 minutes, so...
In some circumstances, the ATC can deny and the will ask you to maintain the expected altitude. The probability of deny can be changed with the ALTITUDE_CHANGE_REQUEST_DENIED_PROBABILITY constant. Note that you cannot change altitude within an approach

Flight
Before asking for a take-off clearance, you must request for a flight clearance. If you don't use a Taxi chart in your flight plan, the TOWER of you start airport will give you this clearance. If you have a Taxi chart, you must contact the controller of the APRON waypoint of the Taxi chart.

Guidance
The ATC gives you vectors to follow precisely the expected track. You must request again each time the controller changes. If you request Guidance whereas you are already in this mode, the ATC stops giving you vectors.
Note that the flight mode does not change. If you are lost and wants your flight to be handled til the next landing you can request for an IFR flight.

Heading left or right
Request for a new heading of a given angle offset toward the left or the right. I never use this request so it's probably buggy. Actually, the ATC inserts a new waypoint at 20 miles from the plane in the requested direction (the plane heading +/- the given angle).
The angle can be edited with the HEADING_CHANGE_REQUEST_DEGREES constant (30 degrees by default)

Landing
The pilot asks for landing instructions. Pay attention on the frequency you use! If you talk to Paris Tower while approaching Bordeaux, Paris will give you a clearance for HIS airport and not for Bordeaux... The ATC should warning in the following updates with some confirmation or whatever...

Landing pattern
This is not really a request. The pilot just says (or should say...) the appropriate Traffic pattern speech.

IFR
If you are flying in VFR, the pilot will request for IFR flight. This option can be used like in real life if you had a wrong timing in your flight and night falls before you reach your airfield, or if you feel lost and want to be vectored by the ATC.
If you fly IFR, the IFR flight will be cancelled and you will be in VFR mode.

Readback
The pilot readback the last ATC message he received. If you want to handle the readback by yourself, make sure the Pilot auto-readback option is disabled (Settings/Pilot's readback).

Repeat
The pilot asks the ATC to repeat its last message.

Report
The pilot says the current state and position of the plane. Use this request (not a request actually, but well...) to report after the ATC has previously asked for a "report over...". After report, the ATC is supposed to validate the next flight segment even if you don't trigger the waypoint.

Runway vacated
For coming 2.3 version...
After landing, you can make the pilot announcing the runway vacation. The ATC will then answer to contact ground if a Taxi chart is available or to taxi to general aviation apron if no Taxi chart is available.

Say again
The ATC repeats exactly the last speech

Speed up or down
Same comments than Altitude up or down. The constant is SPEED_CHANGE_REQUEST_KNOTS.

Take-off
The pilot asks for a take-off clearance. You must contact the ATC of  the airport waypoint in the flight plan to be cleared for take-off

Taxi
The pilot asks for a taxi clearance from the apron to the expected holding short point. If there is a taxi chart in the flight plan, you must contact the ATC of  the GROUND waypoint(s) to be cleared for the flight. If no taxi chart, any of the airport ATCs (Tower, Departure, Center...) will deliver the flight clearance.

Top-of-descent
The pilot announces he is starting the descent. You don't need to use this request since I added this just to make communication with ATC more realistic: in IFR, the pilots do this, usually. It's a sort of IFR report position in a way.

Transit in
The pilots reports the plane situation and asks for a transit. This is the best and more realistic way to awake the ATC when approaching a controlled area (but any of the other requests can awake the controllers!). Note that if you fly VFR, and you want to land, you should use the Landing request. With the Transit in request, the ATC will just allow you to fly over the airport.

Transit out
The pilots says that he leaves the controlled area. The ATC gives the next frequency and says goodbye. If you are too far from the next waypoint where the frequency changes, the ATC should not approve the transit out and ask you to call later. If you were flying in VFR special you should now be VFR.

Weather
The pilot asks for a weather information update. At this stage the ATC gives the wind direction and speed, the QNH and in some cases the transition altitude and/or the the transition level .
