Nice surprise annual profit for AA. Industry got a nice late of year Xmas present revenue boost thanks to Southwest debacle. These analyst predictions were wildly incorrect. I wonder what impact this will have on Q1 and later 2023 projections. Predictions are only as good as the guidance and inform...
Jump to postWith earnings season here, below are projected Q4 earnings (in millions) for airlines. Delta is expected to report first, on Friday 1/13. AAL - $376.9 ALK - $121.7 ALGT - $14.4 DAL - $859.2 HA - (-$35.5) JBLU - $71.2 LUV - $368.1 SAVE - $4.3 SNCY - $5.8 UAL - $693.0 ULCC - $39.2 I dont know how muc...
Jump to postAA’s wages and benefits are inline with its major competitors. If not, this coming round of new contracts will even everything out.
Jump to postI wonder if an ETOPs check has to be performed at some point along the way. I would think that on the eastbound route an ETOPs check would have to be done at MAJ.
Jump to postI had a good opportunity to visit HNL and did some observing. Of course I headed to the end of Lagoon drive to the parking lot. Today, we were in luck. Runway 8L was obviously closed, and arrivals were coming in on 4R. 4R crosses 8R but they were sure cutting it close. I saw many a/c on maybe a 2 mi...
Jump to postAnalyst earning estimates for Q3 as follows. Alaska - $301.6mil Allegiant - $4.2m American - $208.0m Delta - $1,020m Frontier - $23.9m Hawaiian - (-$9.8m) JetBlue - $71.2m Southwest - $261.0m Spirit - (-$8.7m) Sun Country - $3.5m United - $695.8m Analyst forecast full-year losses for American, Hawa...
Jump to postIt doesn’t look like the wheel came off. It looks like the tire failed, and what you’re seeing is the tire carcass falling to the ground. If the wheel assembly had separated/failed, it would have done so during the takeoff roll.
Jump to postI would guess it’s a bad idea to park a C-17 with the T/R’s deployed for an extended period of time. Bugs and birds can find their way inside.
Jump to postLarge airlines usually do coffee make maintenance in-house. They get rotated in and out of service often enough that even some small carriers do the work in-house. Dedicated shops are used, usually employing unlicensed mechanics, with all the test equipment, parts and documentation to do the work.
Jump to postThere are a lot of factors that can determine the time it takes to change an engine. A big one is what equipment the replacement engine has on it. If the inlet cowl has to be changed over or other accessories are missing, then the time increases. Another factor is QA. Once the engine is removed, QA ...
Jump to postUsually when an MD80 tail one is dropped it cracks, so it may not be a simple case of re-installing it.
Jump to postOne area the 777 was ahead of its time was the dual Airplane Information Management Systems, along with centralized maintenance system. All that was never done before.
Jump to postHas UA laid out any cash for this yet?
Jump to postI think SAS was the last major carrier to fly DC-8s across the Atlantic. 1983 I think.
Jump to postI knew a few who got out of the military with only an A license or P license, based on experience
Jump to postCalculating oil consumption is critical to ETOPs. In order to do so properly, you must assume the oil was serviced properly before. If no oil was added for the prior leg, and was entered as serviced when it wasn’t, then at the end of the next leg, oil would be added for both legs, but the flight tim...
Jump to postYou are very correct, those little things burn up the oil. Much more so compared to the IAE. I don’t have the hi-limit consumption rate on hand, but I’m sure it’s more than a pint per hour. GE engines have always used more oil than competitors. The reason why is the oil scavenge system. They must th...
Jump to postI saw a cargo A340-600 at DFW yesterday. Owner was European Cargo.
Jump to postIn the early nineties, I flew AA MD-80 from SJC-SFO and then on to ORD
Jump to postOh my goodness. I just had nightmares about a Professor who studied at Caltech giving us mixed units problems in my Aero Engineering ugrad. Seriously, slugs as a unit of mass? Pound mass vs pound force. SI was just simply more elegant. Unfortunately, having grown up in the US I do think in the so c...
Jump to postAs was stated before, on Airbus, all maintenance manual data such as torques and dimensions are given in metric, with imperial values in parenthesis. Honestly, when working with small dimensions, millimeters are much easier to work with. Brake wear limits are given in millimeters, and I have a milli...
Jump to postAirlines cannot alter tire/wheel size. They can choose from different tire manufacturers. As was mentioned earlier, they can also select an approved wheel half supplier. I know 767’s have different wheel types, because they look different. Bendix is one option. Goodrich and ABSC are other manufactur...
Jump to postNope. Dunno what your airline you are from, but 767-200 are hyd t/r all else pnuematic
Jump to postThere really isn’t much to see up there. You’re not going to find any damage from ground handling. If there is evidence of a bird strike on the SatCom dome, then you would need to go up there. Another possibility would be hail damage inspection work card. For a routine maintenance walk around, the o...
Jump to post767-300s use pneumatics for thrust reversers. They work very well.
Jump to postI would think the crew would want access to the E&E in the event of a fire.
Jump to postAll airliners have forward E&E compartments. On wide bodies, they are accessible from the cabin, narrow bodies they are not. On the 777, the E&E is accessible from the forward cargo. The 787 also has an aft E&E, not accessible from the cabin but from the aft cargo. All E&E compartmen...
Jump to postNever seen this. I’m guessing bird droppings. The warm tailpipe might attract certain types of birds.
Jump to postI’m just wondering what the lockout prodcedure is for an MD-11. I remember on a 767. Installing 3 red lock plates on the outside of the trans cowl and flipping and installing a locking square drive in the center drive unit. Easy enough on the ground, but much more time consuming when you are 2 stori...
Jump to postThere is always a trade off between sophistication and cost. Period..
Jump to postThe flaps on any aircraft, as a rule, will not droop. Take a B747, for instance. The flaps are not driven by an actuator in the sense that the primary flight controls are. The flaps are driven on jackscrews running in transmissions (all that stuff lives under the fairing or canoe) that are driven b...
Jump to postI’m guessing the first few pay steps at DAL are small, and the last step is the big one.
Jump to postNot really. Manufacturers have a “not invented here” mentality.
Jump to postThe chord length is merely a reference length. The actual symbol used in Moment coefficient is l. The reference length is chosen to pertain to the given geometric shape. For an airplane wing, l is the mean chord length.
Jump to postPossible the nose gear mounted taxi light may be replaced by a wing root integrated unit.
Jump to postVFSG’s are for variable frequency electrical systems. A 737, be it an NG or MAX has no such system.
Jump to postThe only welding I ever saw on the airplane was to fix a crack on a pack heat exchanger. That would be in a safe area to weld.
Jump to postActually, you won’t find tire replacement criteria in the AMM, but rather in the individual airlines Procedures Manual. The applicable section on “Wheels and Tires” gives information on tire pressures, replacement criteria and disposition. I’m pretty sure all airlines specify replacing both tires wh...
Jump to postAs was stated earlier, if the tire was found flat on arrival, both the flat tire and the opposite tire have to be replaced. A321 wheels take much longer to change due to brake fans (if equipped). Plus, if the contract maintenance personnel have little experience with these wheels, you are looking at...
Jump to postYou must have flown on a 707-331. They were finally retired in 1979. This was probably planned a long time and there was no point painting them in the new livery unless necessary.
