RJ 700 Cockpit Automated Voice "cell Call"

Sat Dec 15, 2012 6:28 pm

Hello,

I've been meaning to post this. I've heard a cockpit automated voice come from the RJ 700 saying something to the effect of "cell call". Not sure I have that right but believe it's something ending in "call". It's only when we're parked at the gate.

What is this?

Thanks!

You are hearing "SELCAL"

The Wikipedia article can explain what it is: http://en.wikipedia.org/wiki/SELCAL

Except since the CRJ has no chime for an ACARS message, the SELCAL aural alert is used instead. It is incredibly obnoxious hearing that every message you receive.

Most CRJs (all that I've flown personally) have never been equipped with a real SELCAL system. The CRJ does however use an audible 'SELCAL' to alert the crew to a new ACARS message.

Why no real selective calling on the type....

Is there even a need? Best use for SELCAL is when you get only one message in a longer amount of time, typically NATOPS and PACOPS and so, meanwhile CRJ usually fly in rather busy airspaces. Is there even an option for using SELCAL for ex. on eastern coast of the US and eastern Canada?

Why did they install a SELCAL alert system for a system almost (if any) aircraft will have but not one for ACARS which every aircraft will have?

Good question. I don't know the answer to why no ACARS audible alert was installed. I am sure a real SELCAL system is an option that few CRJ operators exercise. SELCAL is most useful when flying over long distances with only HF coverage. With SELCAL, pilots don't have to continuously monitor the HF radio since that system will alert them of incoming messages. As you can see, all things not particularly useful for your average CRJ route.

Canadian Airlines used to have SELCAL on their B737-200/300s, using VHF frequencies. This was a way for Flight Dispatch to maintain flight watch before the days of ACARS. It continued right until the retirement of the type, as it was considered ACARS installation too expensive considering how long the aircraft were remaining.

Early CRJ operators didn't have ACARS, so that likely had to do with no programming of an ACARS chime. Why it hasn't been retrofitted, I have no idea. I can't imagine how many radio calls are missed every day due to that ridiculously loud aural message.

Ironic, isnt it?

Interesting tidbit, thanks longhauler! So do I understand it right, that you would have a radio with SELCAL tuned to company frequency, and when you got a chime, you called home and asked what they wanted?

Yes, that is exactly right. The VHF frequency was the same from Victoria to St. John's, and Com3 was always tuned to this frequency.

Ironically enough, with the source for the B737s from at least 10 different airlines, the actual location of the SELCAL light (push to cancel) was different. I had one occurrence where the button was at the top of the overhead panel, to the right. Probably easy to find on a dark night, but on this bright day, it took us a few minutes of "bing-bong"ing to find it.

It was a "one-off" in the fleet, that I had never before seen! We knew what it was, just not where it was!

Could the SELCAL message be a throwback to the CRJ being related to a bizjet that does fly longer legs but probably lacked ACARS?

It must be an customer option to have an ACARs msg trigger the SELCAL aural and associated EICAS status, as our CRJs don't do that. Instead when we receive an ACARS msg, the printer prints the message automatically. No annoying "SELCAL" aural or anything like that. in addition we'll get a "MSG" annunciation on the CDU scratchpad.

When I worked for a B1900 operator, we had SELCAL using VHF. Most of the time we used it to call company not so much for dispatch to call us as we never bothered to tune the appropriate frequency into the VHF radio.

Tha'ts possible. I've only heard it on 9E CR2s/9s but never on EV CRJs.
