Absolutely! If the groundspeed were to be zero, you would have to be directly into the wind and have your airspeed equal to the wind velocity. I've had 152s going backwards over the ground on several occasions because the wind was faster than we were flying...very strange feeling! This would be the case with your example..you would be going 1 knot in the opposite direction.
Leads to an interesting story...when I was getting my instrument rating, we had a day where there were 60 kt winds at 3000 feet. The lesson that day was holding. So, we decided to try to get a response from Approach Control, and on the outbound leg, we go tour groundspeed down to 15 kts (in IMC, so we didn't really want to push it further, plus, the point was to actually get outbound, not hover ), kept this for several minutes, then coming inbound we firewalled the throttle and got up to 172kts groundspeed. We were at the fix in right about a minute, but our outbound was sooooooo long!

dude, you can fly backwards, i love doing it, pop flaps 40 on the a 172 and find a mega headwind in slow flight, fun as hell great for showing students ICET - indicated, calibrated, Equiv and true as well as ground speed
The only time there is too much fuel onboard, is when you're on fire!

Quoting 2H4 (Reply 4): I've also raced Dodge Vipers around Chrysler's test track near Chelsea, Michigan, and lost miserably.
I haven't tried that yet but if I ever find a day when some testing/racing is going on at the College Station Speedway, if ever again, ( ) I'm gonna try that.....only I hope it is a hybrid so I might have a change of winning.

HAHA yea I have done it as well 10 kts backwards actually! Also kept it at Zero for a while... REALLY WEIRD.. the coolest thing though was 15 kts GS while landing now that was cool! Ahhh you gotta love GPS

I have also raced some cars just outside of YLW there is a drag strip and some cars where screwing around there (looked like they broke in, its in the middle of nowhere) and I just did low and overs over them and they tried to race me... I was in a 152 and well... anyways it was fun...

I know of a flight instructor who used to win bets with his students by telling them he could take off, fly a complete traffic pattern and then land the airplane... all without ever changing his heading.
All it takes is a very, very slow airplane, a windy day, and some judicious use of rudder and power.

Quoting N231YE (Reply 7): Its fun...though passengers don't seem to like the idea of "flying backwards." As a matter of fact, I have talked to ATC'ers who say when they see our target flying backwards, they start to worry.
Yeah, My parents do not like me talking about the negative GS indicated on the GPS, but I love it! Watching the fields and roads and houses come from behind. Kinda weird at first, but lots of fun otherwise.
Quoting N231YE (Reply 7): I have been told by ATC before that when a rinkey-dink C172(R) is on final at 65KIAS, and there is an F-16 on an extended final at like, 400kts, it seems as if the C172 is flying backwards.
I feel like I have heard that before, from the same controller too
P.S. N231YE, how's life treating you lately?

At the time, it was maddening....I just wanted to get home!
Some more interesting uses of slow/zero groundspeeds over the years have been:
- Hanging in place while watching fourth of July fireworks (from a safe distance)
- Viewing Christmas light displays without paying for the entry fee
- Checking out my house, waving to my family, and seeing my dog's tail wag from 1000-1500 feet up
It does, actually. KOEB (Coldwater, MI) has a drive-in immediately adjacent to the airport. In fact, if you choose to divert your attention from the approach and landing, you can watch the movie during final:
You can see the big parking lot under the word "Batavia", and the movie screen just above and to the right.
The best part? The audio is broadcast on an AM frequency, so you can put the ADF to use and tune in.
Not that I've done this, of course. I've just heard about it.
