B-25s with 75mm nose guns went well beyond the experimental stage.

All things being equal, for an airplane to take off in the shortest distance, is it better for the runway to slope uphill (like a "ski jump" aircraft carrier) to give the plane an altitude boost, or to slope downhill (like the carrier Hōshō, or the runway at Narsarsuaq) to give the plane a speed boost?

Airspeed is king so the best way to take off quickly is to get going quickly. If you’re being pedantic (and who here isn’t) ski-jumps don’t decrease the takeoff distance, they just give you more time to accelerate yourself before you crash into the water. In a sense they’re worse since by pointing the plane upwards, it’s making it harder to accelerate by forcing the engine to fight gravity.

quote:The 6,004ft concrete Runway 06/24 is unique in that it has a severe uphill slope landing to the northeast. The beginning of the runway, closest to the water, sits at an elevation of 11ft, while the far end rises at a 1.68% slope to 112ft. Severe! Anyway, while you don’t want a ski jump, you would prefer that the runway level off for a short while before you desire to rotate.

Drawing on those contraptions to race marbles, one down a flat slope and another down an undulating slope, I'd think the best option to minimize horizontal runway distance is first a big downhill bit, then an upward slope to convert the gained energy into upward velocity. Not a practical design, but probably the best if STO is your absolute priority.

They would only be worse if aerodynamic lift at ski-jump AoA was the same as if flat. You can end up at a speed such that aimed engines downward, your lift and AoA plus thrust is fine, but you would crash if just leaving the edge of the ramp with an AoA dictated by landing gear alone. See also: tall nose struts, the Brit F-4 gear, etc. For shortest horizontal distance without worry for vertical distance just drop your planes nose straight down out of a mega tower or airship.

The big lesson in that video is the trick question the chief pilot liked to ask students on their pre-solo phase check. Q: "At what stage in the landing process are you fully committed to landing and unable to go around?" A: _____________________________never_____________________________

Groda posted:That driver was totally on their phone up until the moment of impact. Why do you say that? Street view from the 40mph speed limit parkway next to the runway from which the plane overran. It's less than 50 feet from end of runway to being inside the lane of car traffic. Not the shoulder of the road, but fully inside the car lane.  About 100 feet for the plane to jump the median and cross the opposite direction of traffic. mlmp08 fucked around with this message at 15:18 on Dec 28, 2023 |

There was a youtube series years and years ago where a dude took the 10 hardest landings in the world and spent a video going over the procedures for each one then a video flying the approach. It’s what got me into flight sims, back in the day. Anyways, this is insane: https://www.youtube.com/watch?v=1tC1h1ZCuV0 Also it’s a busy airport because it’s a massive tourist trap town with heavily restricted hours of operation.

We had a check airman fry a pair of engines by doing a go-around after a bounced landing. Specifically, the Q400 has an "oh poo poo!" power setting where you can push the power levers through a detent to get about 20% more power out of the engines, but since that's accomplished by telling the FADEC to ignore a lot of the thermal limits it usually follows, it's not terribly healthy for the engines. In this case, the airplane bounced on landing at an airport surrounded by terrain, and the check airman put the engines into "oh poo poo" power on the go-around, left them there for about 10 minutes, and then didn't bother telling anyone what had happened. Maintenance only found out after a routine download and analysis of the engine data from that airplane a few days later, and apparently the data was so bad that Pratt & Whitney wouldn't allow the airplane to be flown again on those engines, so maintenance got to do a double engine, gearbox, and propeller swap, outdoors, in Montana, in the winter.
