On this page you will find the procedures outlined for crossing the Atlantic with Concorde.
Concorde may have been withdrawn from Real World service but it is still in use with many of the world's Virtual Airlines.
There are three NATs which are used exclusively by Concorde crossing the Atlantic. Track SM is normally used for Westbound flights, SN for Eastbound and SO as necessary. Unlike the tracks for the subsonic aircrafts which change from day to day these tracks are fixed as there is little wind at supersonic cruising levels.
In normal operations SM and SN are the only two tracks used. However traffic levels may vary and Concorde becomes more popular on Flightsim again. As there is little possibility to otherwise separate Concorde aircraft, be prepared to re-route via SO if needed.
N.B. SP is an odd one, it has a standard routing through Shanwick and Santa Maria FIR, but flights to TBPB for instance will follow a random routing after 40°W, therefore all flights routing SP will be treated as random routings.
Coordinates for the NAT Tracks are as follows:

Due to the restrictions that Concorde aircraft face fuelwise on speed and climb restrictions, Concorde aircraft must request their clearance while on Ground, quoting their estimated departure time instead of an estimate for the Oceanic Entry. This should be done approximately 30 minutes before your estimated lift-off time.
This will enable the oceanic controller to facilitate and expedite the flow of traffic for Concorde, enabling it in turn to climb and accelerate in the most optimum manner.
The clearance phraseology is therefore slightly different, as this example will point out using a British Airways Concorde departure from EGLL to KJFK:
Pilot: "Good Evening, Heathrow Delivery, Speedbird Concorde 1, Stand 421, infomation Mike, request clearance to KJFK"
ATC: "Speedbird Concorde 1, cleared to LESLU via Compton3G departure, squawk 5732"
Pilot: "Speedbird Concorde 1, cleared to LESLU via Compton3G departure, squawk 5732"
ATC: "Speedbird Concorde 1, readback correct, contact now Shanwick on 127.900 (12790.0 kHz) for oceanic clearance and report back when ready."
Pilot: "Contact Shanwick Radio on 127.900 (12790.0 kHz) for oceanic clearance, wilco, Speedbird Concorde 1."
Pilot: "Shanwick Radio, Speedbird Concorde 1."
ATC: "Speedbird Concorde 1, Shanwick Radio, pass your message"
Pilot: "Speedbird Concorde 1, request clearance to KJFK via Track SM, estimating Heathrow departure at 1240Z"
ATC: "Speedbird Concorde 1, cleared to KJFK, Track SM, Block FL450 to FL600."
Pilot: "Speedbird Concorde 1, cleared to KJFK, Track SM, Block FL450 to FL600."
ATC: "Speedbird Concorde 1, readback correct, return to previous frequency, good day."
Pilot: "Speedbird Concorde 1, roger, see you later"
Note: the Mach number is omitted as all aircraft fly at the same speeds and thus no separation occurs that way.
At this point you will return to delivery and report when you are fully ready for push and start.
After departure climb and initial acceleration will be granted by the domestic Controller.
Upon reaching LESLU you will be transferred to Shanwick Radio and you will report positions as subsonic aircraft do, you will not need to say the Mach number and you only need to report your current passing level.
The waypoints on SM and SN may be reported as SMxxW(substitute the x for the digits):
Pilot: "Shanwick, Speeedbird Concorde 1, Position report"
ATC: "Speedbird Concorde 1, Shanwick, pass your message"
Pilot: "Speedbird Concorde 1, passed LESLU 1310Z, FL450, Estimating SM15W 1330Z, next is SM20W."
ATC: "Speedbird Concorde 1, passed LESLU 1310Z, FL450, Estimating SM15W 1330Z, next is SM20W."
Pilot: "Speedbird Concorde 1, readback correct."
Please note that position report intervals are considerably shorter than what they are while flying subsonic.
You have a block clearance in which you can climb/descend without further clearance. If, due to ISA deviations, you are unable to achieve the bottom level of the clearance by LESLU that should be not too much a problem, just advise the oceanic controller concerned.
Deceleration and descent requests should not be made on Oceanic frequencies, there should be plenty of distance to landfall in order to do so with domestic ATC.
