There was a hushkit fitted to early 707s, which looks pretty bizarre. I've heard it referred to as the "Buck Rogers". I can't imagine that this was tremendously effective (hence, why it was so difficult to find an image of it): https://i.stack.imgur.com/z6Eji.jpg Would you guys think that ...Jump to post
How wonderful to have you here, N47!! You have summoned me good sir! My bread and butter is actually ground based nav systems so i should be able to shed some light. .

3 installed, 2 required. One can be put on MEL. But, as Starlionblue indicated, the aircraft are certified to stop without their use. Can the AC be dispatched with either #1 or #3 inop? How many airliners have thrust reverse on MEL for dispatch? Or does this vary by the conditions for a given fligh...Jump to post
Very slightly off topic: But what accounts for the different morphologies of various VOR installations? There’s a pretty big discrepancy in sizes. Take for example, the ATL VOR. It’s pretty large… but it’s entirely flat (ie, there isn’t a cone). And I’m not sure what they’re called: The ring of boxe...Jump to post

I flew the A320 for four years and I’m currently in my 737 type rating class/sims. The 737 overhead is as if someone took a box of switches and just threw them at the overhead and where they landed is where the switch went. The A320 was much easier to look at, same for the E175 which was a simpler ...Jump to post
Pretty sure mine (at least the first I could remember) was on a Delta L-1011. Can't beat that! I remember looking out the window and being shocked at how quickly the cars looked like toys.

Biased, but KSAN. At least when passing through Terminal 2 (renovations to T1 are coming!)

As you specifically referenced the 757, those aircraft can climb like a homesick angel, compared to virtually any other jetliner on which you'll fly. I suspect this exacerbates the effects mentioned above, thus making the sinking feeling more pronounced..Jump to post
One of the things you'll notice upon entering the aircraft at the end of a jet bridge is an armature with a wheel on the end, resting on the AC fuselage. The wheel senses changes in height of the aircraft, as people and baggage change its weight while embarking and disembarking. In response, hydraul...Jump to post

Indeed, the message could have been transmitted via ACARS. I wonder though, 10 minutes from touchdown: If there may have been something transmitted on the radio. I'd love to check.

I had an extremely bizarre incident on a flight into SAN last week after which we were met at the jetway with police and paramedics. (It's a long story involving... a cat).

It's like the updated sharklets on the A350. It has no material effect on how we operate the aircraft, so it isn't really an important piece of knowledge.

Can anyone provide insight as to why such a large AC is being utilized for such a thin, domestic route?
Another one, the DC-9 and MD-80 outlived the MD-90. Who knows, they might even outlive the 717. Given the nature of the remaining DC-9 and MD-80 operators (military, third world and embargoed countries), it is anyone's guess if the DC-9 or MD-80 will be the last to retire). No chance of any of the ...Jump to post

How “lightly” is lightly? How much of a derate applied? Is “full” thrust full or at reduced setting or full at the derate? Remember “full” means at the rating, so you can have “full” derate 1 or wash out the derates. Is the 757 so light, the TO is based on reduced thrust on the derate power. And no...Jump to post
It bears repeating, but a heavy B739 at full thrust will accelerate and climb more strongly, in some cases, than a lightly loaded 752 on a derated takeoff. Not a pilot, but I think this statement is correct. Maybe Well I would think "definitely," as the same could be said when comparing T...Jump to post

The landing crew (IIRC the landing aircraft was a 737 classic) had to use the tiller at high speed to avoid the collision.

Looks like a hush kit to me, a modification for sound reduction. It makes the engines more quiet.
