I am wondering if anyone knows where the link would be to find out the performance specs are at gross weight on the MXT 180A Comet? Thanks and I look forward to your responses.

The factory does NOT publish this data.

The numbers on the website are with one (anorexic) pilot and 1/2 tank of gas. Not gross weight. They say 75% cruise 135 MPH and 9 GPH at 7,500 feet. Climb at 920 FPM at sea level. I forget the takeoff and landing numbers but they are around 500 feet, with maybe 1,100 feet to clear a 50 foot obstacle.

Here you go:

BUT...

At gross weight on a 'standard day' I'd say your ROC is more like 500 FPM, 75% cruise at about 120 MPH, and ground roll for takeoff more like 900 feet, and maybe 2,000 feet to climb over a 50 foot obstacle.

Real world service ceiling on a 'standard day' likley around 11,000 feet, not the 15,000 mentioned for the anorexic pilot and 1/2 tank of fuel.

I have found that the number chart for a 180 HP 172 Skyhawk useful for safely estimating what the Comet will do. I believe that the Maule will slightly outperform the Skyhawk to make the use of those figures safe.

Good to know. Yes I did check my POH and the web. I saw the performance specs. I have never measure the distance at gross but it might be a good idea. Most of the time I fly with only 2 people. I helped build a
Grass Strip for a friend. It is grass and is around 1200 feet long at 3600 MSL. I do want to be a crop duster trying to off the strip. That is the main reason I was wondering. Thanks for the input.

The Comet would work there but it depends on many circumstances. The prevailing wind, surrounding terrain, approach/departure angles, slope, surface rolling resistance, OAT...

In the end it's mostly all skill and judgement. :wink:

As I have said in other threads the 180 Trigear will do 90% of what a fat tired 260 will do just fine. With a highly skilled pilot aboard maybe 95%.

Bear in mind though the the other 5-10% difference could get you killed though. :cry:
