Airlines are subject to FCAs, AFPs, GDPs and groundstops. VFR GA traffic is not subject to these things. It definitely is a loophole. AIrlines can sit on the ground in increasing length delays as traffic as GA traffic gets in to those same airports with no delay after taking off VFR. Every single a...
Jump to postClass B separation with VFR aircraft isn't IFR separation. ATC provides VFR aircraft 500' vertical or 1.5 NM from VFR/IFR that weigh more than 19,000 pounds and 500' vertical or target resolution between VFR/IFR aircraft weighing 19,000 lbs or less. But, to your point you're provided separation tho...

Jump to postDCA, LGA and (during certain hours) JFK have a "reservation" system for non-scheduled operators that is essentially first-come, first-served. Not a true "slot" system since the operators and arrival/departure times change from day to day but the goal is the same, i.e. to ration t...
Jump to postAt my company we have a diverse network with some stations having ground power and some not.

Jump to postKind of an unrelated question, but is this also the reason why the autopilot is on like 99% of the time in big jets? Easy to put in unrecoverable situations, but unlike a Cessna 152 they are fast enough to be able to leave you behind the situation easily, but also much more underpowered per kg of w...
Jump to postHuh, I just learned that with the 737, the yaw dampener is linked such that pilots do not need to input rudder when turning, the yaw damper manages the rudder and the pilot manages the spoilers and ailerons. Smoooth turns. The manual may make that claim but it is not entirely true in practice. At h...
Jump to postMDW used to be quite interesting since, in addition to the short runways, a circle-to-land approach was required when landing the 22s (specifically the ILS 31C circle 22L). Now there is an RNAV approach to 22L which has mostly alleviated this but the short runways still mean you have to plant it.
Jump to postIn addition to the previous replies regarding engine anti-ice I would add that +10 is used to add a comfortable buffer above the highest temperature where ice could form, as the "cost" of operating the anti-ice is minimal and the effect of forming (and shedding) ice on the intakes can be r...

I doubt TN has an actual crew base at CDG, but one way they could accomplish this is to operate the PPT-SEA-PPT segments with a "normal" crew and out-base a crew in CDG for the SEA-CDG-SEA segments (which, from the crew's perspective, would actually operate CDG-SEA-CDG). Therefore: The PPT...
Jump to postI'll answer your questions in order: 1. Not sure what you mean by starting a "new batch" of students.

Jump to postThe flight was probably cleared direct HOOTA at some point; the filed route was almost certainly more complicated.

Jump to postAs others have pointed out a shorter airplane does not necessarily improve takeoff performance as most of the weight reduction comes from the reduced payload rather than the minimal reduction in airframe weight, so on those few flights to/from performance-limited airports it would be better for the ...
Jump to postI've never worked at a company large enough to own its own sims, but regarding the rest of your questions: Yes, there are still operational sims for the 737CL, MD-80/90, 727 and even really old types like the 737-200, DC-9 and 707 although they are getting fewer and father between. If an airline doe...
Jump to postSo how do countless corporate operators get away with requiring a type rating? Don’t buy it.

Hawaiian is also set to begin flying for Amazon with A330s but I don't know when that starts.
Finally: I can't imagine how much fuel is being burned whilst arriving aircraft are circling down in 4 spiral stacks to LHR. Presumably having that additional runway would allow for far more fuel-efficient approaches. Any thoughts on this? To be fair (or at least intellectually honest) there are tw...

The only thing I'll add is that while normally dispatch will include a planned route to your alternate in your flight paperwork, this is not included as part of the ATC flight plan; ATC knows what your alternate is but not how you want to get there. There is no guarantee or requirement that ATC will...
Jump to postHow would the issue of 1,000 hours of flying part 121 affect flying for a part 135 operation? I could see flying for the owner of certain aircraft part 91 would not count.

Jump to postTo be fair you asked about "insurmountable" costs associated with your proposal.

I think operating Part 121 would be out of the question (too ...
Jump to postThe alternate flap system is designed to get the airplane on the ground in the event of a hydraulic failure. Typically we train to use flaps 15 when landing with alternate flaps because they take a long time to extend (and retract) - it takes nearly 40 seconds to retract the TE flaps from 40 to 15 i...
Jump to postThe biggest problem with one plane is that when it breaks you are left with no plane, and airplanes break all the time.
