It is normal for engines to spool up during the approach. The initial part of the approach, from cruise level down to approximately 10 miles from the airport, is flown at flight idle power. This is the most efficient way to get down. In the final part of the approach, flaps and landing gear add so much drag that the engines need to be well above idle power. ...

The first thing that you should do is check the NOTAM's for the airport (which of course, you should do before you leave on your flight). Very often, these types of errors have been discovered by someone else and the FAA will have issued a NOTAM to let everyone know. In this case there is no NOTAM, so we would have had no reason to suspect an issue before ...

From FAA INFO 15002: A [snowflake] -XX°C icon will be incrementally added to airport approach plates, beginning Mar 5, 2015. The icon indicates a cold temperature altitude correction will be required on an approach when the reported temperature is, “at or below” the temperature specified for that airport. This looks to be a work-in-progress, as they ...

No because aircraft are categorized by their speed at the runway threshold (1.3 times stall speed). VAT —Speed at threshold used by ICAO (1.3 times stall speed in the landing configuration at maximum certificated landing mass) By knowing the category, ATC is able to use appropriate speeds. The category is not actually listed anywhere, so the controller ...

Yes, blow right through it. You should never deviate from a clearance to "take a beating" later simply because you think you know better than the controller. If the controller is busy it is for a reason, and it is very possible they are extending you on purpose for spacing. You could very well conflict with traffic even more by taking your own turn. It ...

I found the RNAV approach to Steamboat Springs at 7.75°

They can. The Airbus A318 and Embraer E190 both do this in steep approach mode. You can see spoilers extended in this video of a A318 landing and a similar approach in an E190 at London City Airport. Going back further, the Lockheed L-1011 did this with a system called Direct Lift Control. When landing flaps were selected, spoilers raised a set amount. ...

It's better to be low(-ish) and ready for a spot to open, than high and far from that spot. As to why, for busy international airports the answer is really simple: ► There isn't a way to manage it near perfectly (yet). To understand that statement, requires some prerequisites, so I'll try to simplify and summarize the basics: There is the concertina ...

For the GA fleet, there is some historical precedent operating here. Years ago, engines were much less reliable than they are today. Dragging it in generally means that you cannot glide it in if you have a complete power failure. This translates to saying in the event of an engine failure, you are landing off airport with limited selection of landing ...

The "Approaching Minimums" callout is made by the Pilot Monitoring (or, in some cases equipment, the GPWS -- Ground Proximity Warning System) as the aircraft is descending on an instrument approach and has reached an altitude 100 feet above the minimums for that approach -- the Decision Altitude (DA -- typically used for a Cat I ILS, and set as XXX' MSL) or ...

There are actually quite a few reasons to fly an instrument approach, especially one with vertical guidance (like an ILS), even if the weather doesn't require it: It serves as a backup to the visual approach. There are various visual illusions that can cause a pilot to fly an approach too high or too low and monitoring the vertical guidance can help to ...

It is not only the mass that affects the landing speed. Wing area plays an important role as well. A larger wing can lift more weight at the same speed than a smaller wing. If you compare the wing loading of these aircraft the differences are smaller: A388: Maximum landing weight: 391000 kg Wing area: 845 m2 Wing loading: 463 kg/m2 B744: Maximum ...

Objects on the ground are negligible because the radio altimeter is not designed nor used to such high precision. There are several uses of the radio altimeter. The first one is for timing the flare during the last portion of the landing. Since the flare maneuver starts after the aircraft has crossed the runway threshold, at this time the aircraft is over ...

I nominate Sion, Switzerland (LSGS). The IGS for runway 25 is 6°. Here's the vertical profile of the approach plate: Another, ehem, published approach is the Space Shuttle's MLS runway 33 approach at Kennedy Space Center. 20° when light: (Source)

One of the steepest approaches within the CONUS is the LOC/DME approach to Aspen, CO, which has a final approach segment with a recommended approach glideslope of 6.59°.

The FAA AIM, in 4-3-17 and the Air Traffic Controller Handbook, Section 11, explains VFR helicopter operations at controlled airports. The procedure will depend on the airport and the current traffic. Insofar as possible, helicopter operations will be instructed to avoid the flow of fixed-wing aircraft to minimize overall delays; however, there will be ...

SOIA (Simultaneous Offset Instrument Approaches) allow airports with parallel runways that are 750 to 3000 feet apart to conduct (almost) simultaneous approaches to the two runways. At an airport, one runway uses the ILS PRM approach, while the other runway uses an offset LDA PRM approach (with glideslope). SOIA refers to the LDA PRM approach, where another ...

That's nowhere near midflight. You are seeing aircrafts approaching Begumpet Airport (VOHY)'s runway 27. This airport has no airline service, but it is used for some general aviation including VIP flights and as military airbase. The point directly north (about 3 km) from the coordinates you gave (N17° 25' 30", E78° 32' 27") is about 6 km, or 3.2 nm, from ...

This is less of a "big -vs- small" question, and more of a "single-engine -vs- multi-engine" question. So, to answer your question with another question: What would happen if an engine were to fail during the approach in each case? In a single-engine aircraft you want to always be in a position to land if the engine fails, so you don't want to get too ...

This depends on how you were instructed to change frequencies. There three main ways this can happen: Services Terminated ("dropped") Bugsmasher 12345, radar services terminated, squawk VFR and try Podunk Approach on 123.45 for further advisories. This happens to folks on VFR flight following when two facilities can't coordinate a handoff because of ...

did Kai Tak have a straight-in approach to runway 13 for use by steep-approach-certified aircraft? During the 1990s I regularly flew the Hong Kong IGS approach in 747s. At that time, to the best of my knowledge, there was no straight-in approach to runway 13. only the best of the best pilots were allowed to shoot the bent approach to runway 13, and only ...

Commercial jets are not designed to use reverse thrust in flight. With engines mounted under the wing, the turbulence can affect the lift over that section of wing. Tail mounted engines could interfere with the tail. This, in addition to the huge increase in drag, is what causes loss of control, as in the incidents that RedGrittyBrick mentions. Speed brakes ...

Usually when ATC has a need to vector you across the final approach course, they will tell you about it before they do. Something along the lines of "N1234 fly heading 230, vectors across final for spacing.". If they don't and you see that you are getting close, you should ask them if they want you to intercept the course. The AIM addresses this in ...

There are three reasons I can think of: Noise abatement I know that it is not allowed to fly visual approaches at many european airports due to noise abatement. They prohibit it to avoid aircraft flying over residential areas left and right of the approach path Traffic flow At many international airports (e.g. Tokyo) they have to use every second to manage ...

Yes, it's true. Usually called approach or arrival briefing Details will vary according to aircraft and operator but a typical list is NATS: NOTAMs1 ATIS2 notes, chart briefing point by point, date, frequencies, courses, minimums and missed approach procedures. Terrain, minimum safety altitude, which route Special notes for arrival, ...

"Approaching Minimums" you are about at your minimum descent altitude (MDA) or decision altitude (DA). "Minimums" means you've arrived at that altitude. Pilots use those phrases to alert the pilot flying when he us getting close to the ground. At minimums he will either have the runway environment in sight and decide to continue and land on the runway or ...

As denizhanedeer said, it was a circling approach. There is only one charted IFR approach to ESU. It comes in from the northwest and would line up for a straight-in approach to runway 16. Depending on the wind the pilot may have needed runway 34 (same runway from the opposite end) so they would circle around to line up with it. This flight did just that. (...

First allow me to give a quick introduction to RNAV and RNP before geting to SAAAR / RNP AR. Area Navigation (RNAV) is a method of instrument flight rules (IFR) navigation that allows an aircraft to fly on any desired path within the coverage of referenced navigation beacons, rather than navigating directly to and from the beacons. In other words, waypoints ...

First, a caution: IFR procedures can (and do) vary between countries. It is incumbent on the pilot to study the respective authority's Aeronautical Information Publication (AIP) to understand local procedures before flight. When asking questions about instrument flight procedures, it is helpful to know which countries you are specifically traveling through. ...
