It is wild to think that the SR was a VFR airplane.Advanced Flight Modeling Simulation is excited to announce the release of the G5 PFD/HSI avionics add-on. I don't want to know how much the astro-tracker cost. The KC-135B tanker fleet put a DME on every tanker so that the SR flightcrew could head toward the 3 ship tanker config when out of visual range. When they switched over to radio silent missions in the 70s, the only reason for the Nav radio with a DME readout was for air to air refueling. If there was a solid cloud layer above the field with low visibility, then the astro-tracker could not work until the SR got above the cloud layer. So the RSO in the back seat knew precisely where they were at all times, even at FL800+ at M3.4+, without nav radios. On a clear day when the SR would taxi out of the hangar the astro-tracker would automatically lock on to 3 primary stars in just seconds. It had a julian calendar programmed to the millisecond so it would know where the stars should and would be whenever it was operating. The SR-71's astro-tracker (nicknamed R2D2) was an amazing piece of technology for its time. They still hadn't decided what form of pilot interface would be involved if I remember correctly, but I presume the HSI would have had to have been replaced by an LCD or CRT.Ī "little" off topic but this just popped into my head. The Bendix weather radar was already upgraded and had windshear prediction built in but turned off.

Her GPWS would have to be upgraded to include the newer terrain mapping to avoid CFIT accidents which means some form of map database in an FMS. She was already RVSM certified so this wasn't an issue. I believe from what I've been told, that she was going to have to have some form of GPS for Atlantic flying due to safety and security. It is hard to say exactly what she would have had equipment wise today, as we are now 14 years on and the team that were looking into it stopped doing so as soon as the end had been announced.īasically it was thought she could have kept flying until 2016 UNLESS financial matters (like upgrading equipment) proved too costly. When hand flying the maximum is M0.93 to give safety margins and because the shockwaves begin to have a slight effect on control.

The Concorde did have to upgrade a piece of avionics from Collins when the FAA implemented TCAS II 7.1 mandatory on aircraft flying Part 121 above FL180, but I may be a bit off on this point.įirstly, please don't do subsonic cruise at M0.98 as the shockwaves have already started bouncing around and you will burn a lot more fuel, M0.95 was the maximum subsonic cruise with autopilot and autothrottle in command. Would the Concorde be forced to have its avionics upgraded to fly across the Atlantic for example? Would the HSI in Concorde be converted from analogue to digital like several B747-200s have been for example that interface with a FMC where the FMC has replaced the 747-200's original INS system? Would it be utilizing GPS guidance navigation and communication with CPDLC FANS 1/A+? I know FSX does not simulate CPDLC but I am doing my best to type my thinking out here. Well by that time they tell me where I am and then having to tune freq's to get back on course.īut I will "bounce off" a couple of topics that have been mentioned thus far here. in Concorde as an example (M 0.98), and sometimes I get hung up flying from 1 VOR to another, or getting vectored around for a reason or another and then being told to proceed on course as filed. And ATC, especially on VATSIM, can change runway configurations which affects us pilots really fast to a point when they say for example fly to the VOR/GPS 13L approach instead of the xyz approach we gave you 3 minutes ago. So when ATC gives a flightplan amendment, often times they want you to ammend and acknowledge really fast, and a guy like me it is hard to change things quickly unless I am using a FMC or the GTN750 for example. The reason I asked is because when I input a flightplan into other airliners I have to input a SID, a plan with upper level jetways with transitions from 1 jetway to the next jetway, a STAR with specific waypoints where I have to hit them at specific altitudes and speeds, and a corresponding approach into a specific runway that demands various abilities depending upon what type of approach ATC gives you. The GTN750 is not capable of communicating with Concorde's AFCS, so I am glad I asked before doing anything.

Thank you all for your replies, a bit overwhelming for me at first but this is great! I see that I need to brush up on the INS in Concorde, no buts about it.
