Book on flight testing

I am the author of "Homebuilt Aerodynamics and Flight Testing", an introduction mostly intended for aircraft homebuilders or those who perform first flights on experimental aircraft. It covers basic...

If an airplane was overstressed and it resulted in permanent deformation, then it is possible that the damage is visible. Unfortunately fatigue damage is not visible until it results in cracks. In...

We have not solved the issue yet. It may take a while since we are also working on a bunch of other projects. But thanks for everyone's input. I'm confident we can figure it out once we get back to...

It does have a fluxgate compass. When the position lights are turned on the compass does not change, but the ADF needle moves. I tried it at different distances from the NDB, the further away, the...

ADF testing

I'm in the process of testing a new ADF installation. Certain countries still require this to be installed as a backup for IFR flight. I'm not old enough to have actually used ADF during normal...

I agree that the manufacturer of the engine is the best source for that kind of information. I have done a number of new engine installations, and in my opinion the oil temperature limit as specified...

The original author got two things mixed up. A wing with a straight unswept leading edge is more likely to stall outboard first the more it is tapered. This is because the local lift coefficient may...

There was an interesting presesntation by Sean Roberts about spinning the GA-8 Airvan. It was presented at the SETP Flight test safety workshop in 2000. It described the preparation for the spin...

No one wants to give anything away?

I'll start. I'm probably one of the rarer examples of someone who did not start out wanting to be a test pilot but ended up as one after all. I started out as...

I worked for a company building flight simulators consisting of a real panel and yoke, but computer controlled. I used to do "Production flight test" on the simulators. Once I got one where the...

Solved!

We finally got the stall speed down to where it should be. It turned out to be a combination of two separate issues that influenced each other. The wing leading edge contour was not correct and the...

Raked wing tips: I would say the 777 is years behind on that. We had them on gliders more than a decade ago. Just look at a Discus.

We are planning to do something along what Mad Flt S. suggests, starting with more extensive tufting of various parts of the airplane. We know that without the stall strips the stall speed would be...

The stall originates at the stall strips, which are about 30 inches outboard from the fuselage. I tested stall speed at forward and aft CG, in this case no difference, although usually there is about...

It looks like I will not get anywhere with this without telling you everything. I'm an aeronautical engineer and DER test pilot.

The airspeed readings were verified with the GPS triangle method...

I should have posted more details, sorry. I checked the airspeed indications on both airplanes with GPS, they are right on. Both are new airplanes (this is in the US). The one with the higher stall...

The airplane with the higher stall speed has been used as a test airplane. The stall is aft stick limited. I have eliminated the horizontal tail and elevator authority, it is sufficient to get it...

Stall speed

I would like to collect some ideas on why two airplanes of the same model, which look the same, at the same weight & CG can have almost 10% difference in stall speed (power off, full flaps)? I have...

We tried winglets on the Columbia 400 and found that they improved directional stability during stalls / stall characteristics, but spin recovery was worse so we dropped them.
