Some light aircraft now have airframe parachutes. If a pilot does have to pull the chute on a Cirrus (for example), is the aircraft flyable or at least repairable after landing or is it a write-off? What G forces are involved in the impact?
I realize that there are lots of possible variables here, but let's assume that the parachute deploys correctly and in plenty of time for a stabilized descent; touchdown is in 'ideal' conditions, i.e. on level, unobstructed ground; and impact forces are as described in the Cirrus CAPS guide:
The airplane will assume its touchdown attitude to optimize occupant protection. The airplane will descend under the canopy at less than 1700 fpm and ground impact is expected to be equivalent to dropping from a height of 13 feet (about 4 meters). The airframe, seats and landing gear are all designed to absorb the impact energy.
For the Cirrus at least, it sounds like that the odds are that the plane will be a loss. Thus far of 53 CAP deployments, only "9 CAPS Planes that Were Repaired and Flew Again"
Revision A7 of the Cirrus SR22 POH currently states "CAPS deployment is expected to result in damage to the airframe" that updates the earlier language that "The system is intended to saves the lives of the occupants but will most likely destroy the aircraft."

If I were to redo my avionics to only include a WAAS GPS unit and two comm radios, would anything prevent me from operating IFR? 14 CFR 91.205(d) only states that my airplane must have: (2) Two-way radio communication and navigation equipment suitable for the route to be flown. I'm aware that this is not the most bulletproof way to fly hard IFR. In this case, assume that the aircraft is primarily used for currency/proficiency and the occasional light IFR flight.
Per FAR 91.307: Unless each occupant of the aircraft is wearing an approved parachute, no pilot of a civil aircraft carrying any person (other than a crewmember) may execute any intentional maneuver that exceeds... So if I'm flying aerobatics solo, I'm not required to have a parachute. But if I have a passenger, both are required to have one. What is the rationale for that? I suppose that in something like a Super Decathlon, where the pilot must exit the plane before the passenger, it would be senseless to have one for the passenger but not the pilot. But is there anything more to this?
This question is about light, tricycle, single engine aircraft. I have made it a habit to raise the flaps right after touchdown (when the nosewheel is on the ground). My instructor used to do... of fiddling with the flaps lever (which is a something I don't even have to think about) My question is: Is it really a bad idea to raise the flaps that soon after landing? Or is it actually a good habit? (I... effect, reducing the risk of loss of directional control after landing (less important) it's part of the after landing checklist, so when it's done, it's done However, I was recently checked out
I've never seen a 727's aft stairs open, but presumably, based on an Wikipedia image and common sense, they do reach the ground when the aircraft is on the ground. Furthermore, (as I understand... during landing, they would impact the ground during landing and, given the pitch, do more than scrape the ground and cause damage to the aircraft. However, DB Cooper's jump left the aft stairs open... there were slightly more important things to deal with). If DB Cooper's flight did land without damage, why is that—did the 727's aft stairs not fully touch the ground? If the stairs did impact
I'm very interested to learn if there are (m)any (major) (commercial) airports that have runways further away from the terminal(s) than Schiphol's Polderbaan. Which airport is "in the lead" in this respect? The northern end of the Polderbaan, the last runway to be constructed, is 7 km (4.3 mi) north of the control tower, causing taxi times of up to 20 minutes to the terminal. [...] Newest runway, opened 2003. Located to reduce the noise impact on the surrounding population; aircraft have a lengthy 15-minute taxi to and from the Terminal. Wikipedia
I'm a student pursuing a US Private Pilot License, and recently scheduled my checkride. I've been training in a 1981 Piper Warrior (PA-28-161), but if its annual goes sour I may have to take my club's 1980 Piper Archer (PA-28-181). I have well over §61.109's 40 hours in the Warrior alone, and only ~10 hours in the Archer. I have a separate club checkout and CFI solo endorsement for each... plane was fine, and I can't find any Part 61 regulations that are specific to experience in one make/model aside from adding an experimental aircraft as part §61.63(h)(1), which is what I assume
of occurrence is approximately: 3/16/2014 6:09pm CST I have also verified FlightAware is ALSO showing the same weird glitch. See below "yellow" highlighted airplane: Same A/C from FlightRadar24...I was looking through my virtual radar logs one of the days and found this "glitchy" ADS-B behavior. I am almost 100% sure that this is not due to my antenna or setup since two independent different radars confirmed this weird behavior from FlightRadar24. Also A/C before and after this one did not exhibit this behavior. Does anybody have any thoughts as to what may be happening??? Why
Antennas sticking out of an aircraft obviously increase profile drag, but the folks who design antennas have done a lot to improve aerodynamics: High performance aircraft can have antennas mounted inside of fiberglass components like wingtips, and flush-mounte antennas are available for transponders and DME equipment. For slower light GA aircraft more aerodynamic antennas are also available (e.g. blade-style transponder antennas are available which produce about 80% less drag than older spike-and-ball style antennas), measured at 250 MPH. Since the average light GA aircraft has a VNE below
According to Airbus: ‐ After the flight crew selects reverse thrust, they must perform a full stop landing. Does it really make sense to have this limitation, and why? What happens if you realise there's not enough space to land, and you've still got adequate speed?
