A derate is like installing an engine with different ratings. It’s a selection in the FMS that tells the FADEC to limit thrust to a fixed percentage below the installation’s full rating. 10% and 20% derate being a common option, but as noted could be different, operator option. The modern planes usu...Jump to post
YouTube titles are very useful. Look up Kai Tak videos, dozens of landings like this one.
Transpo ‘72 at KIAD was great, also a one-off
Where is the downsizing happening?
AI could have bought the commercial aircraft side, but to what end? The CRJ/Q400 didn’t need the cash infusion. AI brings little to the Business Aircraft side—commercial aircraft sales is entirely different animal.
Scope ain’t changing and, as pilots become scarcer, mainline will be taking back more flying—RJs will either be upgauged or routes cancelled; NB flying will more to larger narrow bodies (A321/ B739) or wide bodies at peak hours. Off hours services will be rolled into larger mainline service, RJ off-...Jump to post
Yes, because by increasing thrust in the OEI case, if the airspeed is below Vmcg or Vmca, the pilot could lose control due to asymmetric thrust. Think of Vmcg and Vmca as redlines below which you must not go in asymmetric conditions and you won’t know where you are in relation to them when increasin...Jump to post
AA and EA used QFE, not a weird form of it, though. The company provided the QFE setting, the main altimeters were set for the approach using QFE. The third altimeter was set to QNH for reference to assigned altitudes. That’s EA procedure, I doubt AA varied much. I was drilled into to the point when...Jump to post
By reducing thrust thru the derate, the Vmcg and/or Vmca is reduced allowing for lower V1, Vr and V2 speeds. Think of a derate as installing a different engine on the wing with different speeds. Lower speeds means reduced distances or, better yet, greater loads off a fixed distance i.e. a defined ru...Jump to post
It was less due to props than tailwheels.
Are you asking about “derate”or “reduced thrust” (assumed temp method)? Two different things. Usually reduced thrust is prohibited on contaminated runways, but a derate might well help things.
Just sayin’ it’s not used in radio transmissions and I’d bet a lot US pilots rarely use it—it’s not in the AIM, P/CG or FAAO 7110.65.
This is the guidance the FAA gives its controllers. 2−7−2. ALTIMETER SETTING ISSUANCE BELOW LOWEST USABLE FL a. TERMINAL. Identify the source of an altimeter setting when issued for a location other than the aircraft’s departure or destination airport. b. EN ROUTE. Identify the source of all altimet...Jump to post
ChrisKen, 45 years of flying, civil and military, in the US, I never heard QNH used until I went overseas. Before extensive civil international flying, even in the USAF, i rarely heard the term used as we operated mostly out of USAF bases. If you fly in the US, ask domestic pilots and try using it w...Jump to post
Never used or taught in the US.
First, just replacing the avionics won’t accomplish “commonality”; the FBW laws are different for one big thing. Second, you can’t “.inflate” the fuselage a bit without a large certification program. Dimensions alone do not describe an airplane despite what a.netters think. A fella named Paul Tellie...Jump to post
I can almost guarantee you US controllers and US domestic pilots haven’t an idea what “QNH” means. It just isn’t used or taught.
Does the a220 not have auto trim ? The a320 does . Airbus has Vnav but calls it des mode . The fms is different and displays but airbus has moved that way anyway with the a350. The main hurdle will be if the flight control laws are very different . If they can get conversion down to a short course ...Jump to post
There’s a huge corruption and red tape cost to putting work in Brazil. This will be especially important in a high-tech industry that Brazil has put lots of “face” into like aerospace. Boeing will be fought hard.
Under the Railroad Labor Act (RLA), they are different in detail, but not character. All US carrier contracts are similar in outline and vary in detail. In regulation, they was strong pattern bargaining, but bankruptcies and mergers have caused many diversions and variations. Usually, negotiations b...Jump to post
Scope is Section One in US ALPA contracts, it defines the scope of work to be performed under the contract—what is done, by whom and any exceptions. Originally, it was simple, all flying under the airline’s colors will be done by pilots on the seniority list. It precludes any use of non-seniority pi...Jump to post
Heck, I’m an American and have be caught using “QNH” after flying lots of international.
I don't own an airline. I fly them. So yes, I care about how my rear end fits and feels in a seat. It's remarkable, for an enthusiast forum, how much this forum actually detests passengers and dismisses their concerns. You'll find an apologist for any airline at any time of the day on this forum.

The #2 (center) engine has a higher, by .03 EPR, than #1 and #3 due to the outboard engines are bleed for the A/C packs and the center engine isn’t bleed. The engines are all the same on the DC-10; probably a visual illusion due to the long cowl thru the fin. Although, it could be a rearrangement of...Jump to post
If a market doesn’t develop enough revenue to support the service, the service (planes, crew and resources) will be deployed elsewhere, simple free market. Small cities are “entitled” to air service.

Sully has made it his mission to destroy regional aviation by pushing insane pilot hour minimums. So, airline pilots shouldn’t be required to be licensed as AIRLINE PILOT? Do you really think 250hours, or 6 weeks of full-time work qualifies one to be an airline pilot. Would you go to a doctor with ...Jump to post
It’s just using a telephoto lens to compress the distance between the foreground and the plane in the background. Old photog trick.
The G7000 is nearly identical, to the pilot, as the C-Series—speed stable; fixed, or nearly so, side sticks. Pilot sets a desired speed and it’s trimmed automatically to maintain that speed. Throttles are back-driven. I haven’t been in G500; but I’m a bit dubious moving side sticks are all that much...Jump to post
I agree with you, but experience tells me operators frequently don’t care. I always admired 3M’s department philosophy-GII (III, IV, V) or everything; MSP to CHI or MSP-TYO. Trying to always size the plane to the mission wastes more money than it saves often.
First, multiple direction runways were a holdover from the early days of aviation when landing into the wind was advantageous for tailwheel planes. The first airports were circulat grass fields and one always landed directly into the wind. Second, the tremendous growth in traffic meant parallel runw...Jump to post
Generally, stretches involve an amendment to the TC and tests as needed but not a whole new certification test. Like all aviation questions, the answer is, “.it depends”. Save on training costs? That’s a hoot. I’ve visited departments with three and four types. The record was a BBJ, Falcon.900: Cita...Jump to post
While “roger” means “I have received your transmission”; just stating your call sign has, in the US, the same thing.
