Re: Do gate size restrictions matter for freighters

Yes cargo operators care about gate size. Companies like FedEx and UPS have gates designed very close together to maximize the space available, especially at hubs and larger bases. These gate often times have teather boxes which house the hooks for the anti-tip teathers, so changing a gate would req...

Re: Which airliners have two jackscrew assemblies to control their horizontal stabilizer?

E145 has two screws, but it all one unit. Either motor can run both screws if needed.

Re: Why do E145 Aircraft have to utilize a jetway adapter

Training was to look for the window. Door with a window means conventional door, no window means airstairs. Trans States was a mess for a bunch of different reasons though, their procedures and equipment was always different from the other 145 operators. Did the E145 ever fly as UAX or was it after...

Re: Why do ailerons and speed brake panels become so active during the approach phase of flight?

So if the outboard ailerons are locked out during high speed cruise, I guess the 747 I was on was in the approach phase if I was seeing those move since they wouldn't move during cruise. I still can't quite see why the DC-10 showed less aileron and speed brake movement during the approach. I only f...

Re: Why do ailerons and speed brake panels become so active during the approach phase of flight?

Less airspeed requires greater deflection of the flight control surfaces. Some, like the 10-10 and 10-30, have an inboard and an outboard aileron. The inboard is an "all speed" aileron that is always active and the outboard is only active at lower speeds. So there is a lot more movement, i...

Re: Question For the Mechanics: Which Commercial Aircraft Have Been Easiest and Most Difficult For You to Work On?

Like what was said before, all airplanes have the good and the bad. I enjoyed the E145, the ATR, A300 and 757/767. Don't have very many good memories from working on the CRJ200 but the 700/900 was better. Didn't like the E120. The MD10/11 are a mixed bag. The 10's aren't bad except for the #2 engine...

Re: United orders supersonic planes from Boom (was: Big United Announcement Coming Up?)

Since it's a 65-88 seater that puts it right in the regional range so I guess SkyWest will operate them. Can't pay top wages to pilot flying a jet with 70 seats.

I would imagine that they did not have any kinda of vendor agreement in place. Without AA being an approved vendor the is no way for them to transfer the part legally, at least not quickly. Every part has to have a paper trail to satisfy the FAA requirements. Personally, I had an AA aircraft on a we...

Re: Post maitenance test flight

Most of the time it is the operators GMM (General Maintenance Manual) that will specify conditions where a test flight is required beyond anything called out in the AMM (Aircraft Maintenance Manual). The AMM usually has very few, if any requirements for a flight. Some will have certain calibration f...

Don't suppose anybody has any information on the load they where carrying? Was it full? Did they have a bunch of voided positions? Just curious if there was the possibility of a shift in CG due to some of the cans coming loose in the turbulence. Shouldn't be a way for them to come loose, but nothing...

Re: Future engine improvements

You can get a marked improvement in efficiency by going to a single engine, half the engines half the fuel, duh!

BTW its a joke for those of you whom have lost their online sense of humor. Oh, and a manual transmission is driving, automatic is riding.

Lost revenue is not counted directly in the cost of checks. Most operators, except around Thanksgiving and Christmas, plan on having planes in check all the time. They are usually scheduled into heavy mx "nose-to-tail", meaning when one is released the next is ready for induction. For exam...

Re: Engine over the fuselage question

Could be also, the air gets "squeezed" between the engine and fuselage if they are on top of the wing and can cause some drag and design consideration. I remember when the EMB-145 was being developed, one of the original designs had the engines on top of the wing. Basically, converting a E...

Re: Is there a minimum "rest" time for an aircraft?

When I was working for the regionals, we made up a lot of time on turns. The plane would come in 20-30 minutes late on a 45 minute turn and leave a few minutes early. Especially, when they were tankering fuel for short hops.

Re: Static Wick

Some planes, like the EMB-135/140/145 the wicks themselves are threaded on the end and screw into the base. The base however is basically, glued to the aircraft and is usually what gets blown of during a lighting strike or knocked off. They are easy to replace, but require cure time.
