What comes after a DA40?

Post by Boatguy »

I'll play! First the "ground rules"... level flight.

I'll start the bidding at 172, setting the bar low so everyone else can play too!

I flew in a friends C152; on a windy day. At full throttle around 5K we had a ground speed of 5 KIAS per the installed GPS; and could pull the throttle back and watch the ground go in reverse. It was rather fun.

With my old, slow bird I'm out of the running for the best top speed. So I'd be looking to grab for the lowest. Maybe the highest negative value.

Given the way GPS works, I'm guessing it'd be tricky to document negative relative groundspeed. I'd have to capture heading, track and GS all at once. It would also take a pretty strong wind. I'm guessing I could probably pull off 40 KIAS, but the calibration graph suggests KCAS would be more like 50 KCAS. At any decent altitude for me, that'd mean something 55-60 KTAS.

My entry is from a flight last August from near Des Moines, IA to Gainesville, TX. A 26 Kt tailwind added to my 157 TAS yielded 183 Kt GS at 13,000 MSL. My DA40NG was burning 7.9 gph at 88% power. Density altitude was 13,675.

When I bought my plane, we were flying to Victorville. I actually had 208 kt ground speed, but until I decided that I wanted to take picture, we were at 198. At one point, we had a 65kt Imagetailwind. I knew I'd never see those speeds again

The "ground rules" were level flight. The PFD shows -850FPM. 148KIAS is impressively fast, but...

None the less, with a 65kt tailwind the 208kt GS is certainly credible.

A few years ago I was flying from KUIN (Quincy, Illinois) to KAUH (Aurora, NE). It was actually a pretty slow flight since we had pretty much a direct 30 - 35 knot headwind the entire flight even though we were down low at only 4,500 ft. - arggg...

However, we were VFR with flight following and there was a glitch on the hand off between Minneapolis Center and Kansas City Center about midway in the flight. The end result was that the Flightaware Flight Track Log indicates we had a 314 knot ground speed in level flight for about a minute at 2:17:38 PM during the flight! Check out the Flightaware track link below:

My guess is that's likely a the record for a DA40 :)!

Now we know how they decide where to hand us off to the next center. It’s when we’re entering a wormhole.
