A local Decathlon recently had its ailerons jammed by the clip from a Bose headset. Pilot managed to fly it to the airport and fortunately it unjammed on final approach. Holes in the floor of a Decathlon so easy for pens, phones etc to get to where they can jam the ailerons or elevator.

When I bought the airplane it was using tacho so I continued with that for a short while until I bought a flight switch. The flight switch was U/S for a short while so I used time on my wristwatch from take-off to landing.

google found this https://members.raa.asn.au/storage/cta-faqs.pdf which, as I expected, states that it requires more than just an RPL.

The original question was simply “What aircraft had three decks?” I don’t know much of the German language but it seems to me that Driedecker is “three decks”?

What landing gear did the S-1 have? Lockable tailwheel keeps it straight whereas the standard Maule with vague steering allowed the tail to swing. Spring main landing gear instead of bungees tamed the bouncing.

Fokker Dr.I (Dreidecker

"If the pilot had selected some or full flap prior to or during the left turn, he would have been able to extend his glide distance further and reduce the aircraft’s stall speed, and potentially the aircraft’s speed at impact." He is not saying that the glide angle is better with flaps down. "However, given the location of the aircraft when he commenced the left turn, and the nature of the surrounding terrain, it is very unlikely that a collision with terrain could have been avoided." So extending the glide is insignificant compared to stalling and hitting the ground hard. "The aircraft was at about 60 ft (see GPS information) and had a groundspeed of about 124 kt (about 230 km/h)." .... "If full flap had been selected, the stall speeds would have been reduced by about 10 mph (9 kt) for the same bank angle." ... "Given the stall warning was intermittently sounding for the last 7 seconds, and the indicated airspeed decreased from 65 kt to 60 kt, it is very likely that the aircraft was close to the stall speed during this period. In the last 1–2 seconds, as the bank angle increased to about 60° and the indicated airspeed was about 60 kt, the aircraft may have entered the stall. The pilot’s use of left rudder in this period increased the potential to stall." "All of the options were likely to result in at least some level of damage and/or injury. However, with the benefit of hindsight and a detailed consideration of all the available information, the option likely to result in the least damage or injury was to land the aircraft ahead on the remainder of the beach (heading north)." Hindsight is for us to learn from. "Regardless of whether the aircraft stalled, the aircraft impacted terrain with little or no control and a significant descent rate." That is the thing to avoid. Interesting that camera and camera memory disappeared.

Suggest that you fix the spelling of the hotshot star aerobatic pilots - Jock Folan and Gerard. I can't make it as I have a birthday party to go to. I was in Narromine last weekend however so caught up with other hotshot aerobatic pilots.

Good start! I didn't see your qualifying statement about "flying straight ahead" and stall. Anyway, my comment is pretty much the same. The objective with the use of rudder in a stall is NOT to keep the wings level, particularly not to return the wings to level after an entry to an incipient spin.

When people ask me that I generally get them (in an aeroplane) to do a stall in a turn and then recover. I don’t offer any advice as anyone who has learnt to fly or done a flight review in recent years per CAsA’s Part 61 should be competent at them.

A few points in response: I used to be scared of stalls when I was learning to fly. I know quite a few instructors who are scared of them. So your situation is quite common and there is a cure as Kyle suggested. "they are safe" - well, too many of my friends and acquaintances have been killed as a result of a stall, so nope, not necessarily. "using the rudder to keep the wings level" - that can be very dangerous so your "easing the control column forward without worrying about using the rudder to keep the wings level" is very much safer. "worrying that if I don't keep the wings level I will spin" - keeping the wings level has diddly squat to do whether you spin or not. "And die." Potentially, if you do the wrong thing and that seems likely from your post. I recommend that you now read https://www.faa.gov/regulations_policies/handbooks_manuals/aviation/airplane_handbook/media/06_afh_ch4.pdf

As much as 6K vis? Very much less down the road at Narromine.

I guess that it is something like this https://www.iac.org/media-gallery/detail/3847/10313

The DR-109 is noticeably different. Can’t think what it is at the moment.

Obviously a big gap for him but he has been building up other aspects of his business - not new as Red Bull had a long pause a while back - e.g. just before the last race he had a charter to the outback in his King Air.

For info, I note that many put stuff like this in checklists: "check oil pressure in green within 30 seconds". Lycoming actually states: "If minimum oil pressure is not indicated within thirty seconds, stop engine ...". Short story is that it does not have to be within "the green". Quite a few variables such as different installations in different aeroplanes (my aerobatic aircraft have lots of extra oil hoses for the pump to work against when cold especially), ambient temperature and type/grade of oil.

Interesting question (miserable weather this weekend so people get to put up with me online). It seems that the book figure is 47 KIAS? I can't find the conversion to CAS. My copy of the Owner's Handbook states that the stall speed is 57 mph = 50 kts - perhaps that is CAS? I wonder if RAA knows - surely they have looked at it and determined whether it complies with the requirement for a Vso of 45 kts? Pretty simple to me - if it complies then OK and if it doesn't comply then cannot be registered RAA (I recall that we've seen this before). Interesting that CAO 95.55 simply refers to a Vso of 45 kts without stating whether it is ASIR, IAS, CAS etc. The CAO refers to the CASR dictionary which has a simple definition of Vso without stating whether it is ASIR, IAS, CAS etc. That dictionary refers to the USA FARs section 1.2 which has the same definition also without stating whether it is ASIR, IAS, CAS etc. So, nowhere do the rules state that your Vso has to be CAS so I guess you get to choose yourself? Fit an ASI which has lots of error in the right direction and demonstrate it shows less than 45 at the stall.

Refer ERSA for alternatives to NAIPS.

Interesting that from https://cafe.foundation/v2/pdf_cafe_apr/rv-9a.pdf at 797 kg the stall speed is 42.7 KCAS.

Actually they are not CASA's words - Australian Flying Magazine got it wrong. At least CASA knows that a PA-22 is not a Tomahawk. The magazine introduced IAS but CASA just stated stall speed of 45 kts per the CAO so I guess they haven't yet worked out if it is supposed to be IAS or CAS. The STCs for VGs on little aeroplanes generally don't come with a POH supplement showing the lower stall speeds and performance per https://www.ntsb.gov/_layouts/ntsb.aviation/brief.aspx?ev_id=20001212X20122&key=1 so officially the stall speed has not changed.

Certified aeroplanes are required to determine Vso in CAS however the figure may not be in the AFM/POH as I have discovered. Yep, I think someone in CASA will eventually work it out. ...... Even homebuilt aircraft are supposed to determine stall speed in CAS per https://www.casa.gov.au/file/122726/download?token=NFLC3fMe per https://www.casa.gov.au/file/152031/download?token=8ztVbEcR so CASA thinks that the figures are available. I am sceptical.

I think you will find that it is stall speed in CAS not IAS. Generally, CAS is a higher figure than IAS. Then there is the technical issue of determining stall speed in CAS for some.
