Hot-air Balloons are already made with large holes in them. They are called vents. They can be located in the balloon’s top or sides. They tend to be much much larger than the 4-inch diameter you described in your question. But, their opening and closing are controlled by the pilots. Research the FAA Balloon Flying Handbook. It will give you much more ...

Flaps generate more lift at the expense of more drag. Their primary purpose is to allow you to fly slower, with the side effect of letting you descend more steeply without gaining speed. Your default should always be to use the VSGI when one is available, and to try to stay on glide slope, unless you are deliberately doing something unusual like a short ...

It is more important that your approach is stabilized and safe than you are strictly on slope (i.e. two red/two white). But let's discuss a few things before extending this answer. ATC is not terribly concerned with where exactly you touch down (especially in a light aircraft) so long as you don't run off the end of the runway. When cleared to land the whole ...

Remember, glidepath guidance has its apex or ending point centered on the official precision landing markings (what most people call the thousand footers). This is officially called the aimpoint or aiming point. Large aircraft do not have much float when flaring. They both aim and touch down near the same point. Walk out to a point abeam the thousand footers....

Absent an explicit instruction to the contrary, VFR traffic can do whatever it wants in class C/D/E airspace. ATC is not supposed to give you both lateral and vertical control instructions at the same time because that could interfere with your ability to maintain VFR cloud clearance requirements. Class B has different cloud clearance, so you will almost ...

The Doak VZ-4 twin ducted propulsor flew in 1958, the Bell X-22 took that up to four in 1966. So yes, people have been thinking about it for over half a century. Analogously to any tailless aircraft, the side-by-side twin is sensitive to CG in vertical mode and trim must be closely maintained. Although not ducted, the Boeing V-22 Osprey convertiplane suffers ...

balked landing : is a go-around initiated after touchdown but before thrust reverser selection . (source: Term from Boeing bulletin)

Disclaimer: I'm not an airline pilot so don't just take my word and apply it in a real world environment From my understanding: TOGA means takeoff/go around and is usually a thrust setting of the engine. It can also be the vertical or lateral mode of an autopilot/flight director. I haven't seen anyone referring TOGA as a situation of flight though. "I've ...

Immediately after touchdown, the autobrakes will start to function, and may start applying the brakes depending on the aircraft's deceleration and the commanded deceleration. If the pilot hasn't yet started to deploy the thrust reversers, a go-around is still possible at this point. Advancing the throttles will disengage the autobrakes, and it's a normal ...

Depending on the aircraft, flaps can be set at one of several different settings anywhere from 5° to 40° (or more, from what I understand). All of these settings are considered "down". (The exact flap angle depends on the aircraft, current weight, air temp and other factors and more than one is "appropriate" for take off or landing depending on these ...
