Genuine slow flight.

[Nark]

This was my last flight in the sweetheart, "Ads-6".

I've flown many hours at 0 IAS, and have a number of pictures of it, so not too impressed anymore.

However, with a great south wind in the area today, I got as slow as 17.1 ground speed, but I couldn't get the iphone to snap the picture quickly enough so this is what I got:




My next gig has me cruising at 5 times what I used too. So much for having fun at work...

[Expat]

Yeah... slow day...

[Mostly Harmless]

I've backed an airplane up (flown backwards) faster than that laddie.

[KAG]

I've had Pa28-140's going backwards a few times, freaks the hell out of oeple the first time they see it.

[FlaplessDork]

I had the GPS read 30 kts backwards in a Chinook wind near the Rockies in a 172 many-o-times.

[bmc]

You'll look back on this as the most fun job you've had.

Good luck on the next adventure.

17 kts going backwards. C152

[Doc]

Took off from Guelph, backed up and landed on the same runway with no turns....Apache. I seem to remember a wee bit of a wind....

[Cat Driver]

Took off climbed to five hundred feet descended and landed all with zero ground speed in zero wind conditions.....Windsor Ont. Hughes 300.

Cheater! Doesn't count if your wings spin in circles.
The best I've done is 5kts backwards, so I really don't have any bragging rights at all.

[costermonger]

I've managed 16kts backwards in a 172, probably greater in a 152 but they don't have GPS.

Doc, you've given me a goal to work towards..

"I've flown many hours at 0 IAS"

How do you do that?

I was wondering the same thing.

Maybe he meant in the bar.

[GoinNowhereFast]

I'm guessing the same method Cat used to get his 0 groundspeed.

I'd hate to get all flight instructor on you ass, but here it goes:

If you guys can remember wayyyy back to ground school when you learned that the airspeed indicator works off the differential pressure of ram air through the pitot tube and static pressure. When the pitot tube is blocked the ASI acts like an altimeter because it's only working with static pressure at that point.

When towing banners, I fly at a very high angle of attack. aka slow flight. Since the pitot tube on Supercubs, isn't the most high-tech device, the ram airflow can easily be blocked given the right AoA.

Here is an example:

[HS-748 2A]

When the pitot tube is blocked the ASI acts like an altimeter because it's only working with static pressure at that point.

Hate to get all AME on

you ass

but a 'blocked' pitot's got jack to do with your picture.

If you took off with a blocked pitot and climbed, your ASI reading would increase steadilly from zero.

In above picture, your ASI is indicating zero which by default means both pitot and static are equal.

You're just not getting any effective ram air in the pitot tube.
