I may be wrong on this and if I am, there is sombody on this forum will be happy to tell me about it.

During a pre heat with a Red Devil or other such apparatus, you are heating the air and that in turn heats the engine. A cowl cover would be a real asset.

During a pre heat with a Tannis you are heating the sump as well as all six jugs. Not sure how necessary a cowl cover is going to be considering where I live.

I have a lot less experience with this than some on this forum but probably more experience than you guys in Arizona.

You want the engine blanket. Even with a simple sump heater, the entire engine compartment will be toasty warm. Battery, carb, all like the heat. And if you go wander out to where it's cold, the blanket will hold the engine heat for a whole lotta hours so you can start and go home.

It's up at Kivalina where a snow bank caught it and pulled it off the runway while landing back in '95. Still there, and looks kind of cool framed in by the whale ribs.

ANC95LA046
On April 17, 1995, about 1300 Alaska daylight time, a Douglas C54GDC airplane, N898AL, sustained substantial damage while landing at the Kivalina Airport, Kivalina, Alaska. Neither the airline transport certificated captain, the commercial certificated copilot, or the company employee jump seat rider were injured. The 14 CFR Part 91 flight was being operated in visual meteorological conditions. A company flight plan was filed. The airplane was hauling fuel oil to be distributed at Kivalina.

The pilot reported in his written report to the NTSB that he had checked with the Galena Federal Aviation Administration Flight Service Station prior to departing for Kivalina. He said the only Notice To Airmen he received for Kivalina was that the runway had thin, packed snow on it. Upon reaching Kivalina, the pilot said he overflew the runway, and saw that, "...some of the runway lights were visible, none of the snow berms or snow drifts were visible. A little gravel was showing on the center line of the runway. Because of the time of day, there were no shades or any other indications of the height of the snow surrounding the runway..." The pilot's statement continues: "Shortly after touchdown (within 200' of the threshold and on the centerline) we hit with the left main gear a snow drift which pulled the airplane to the left. Staying a little left of the centerline we hit several more snow berms with the left main gear...the last snow berm we hit made the airplane pivot to the left stopping in the packed snow pointing approximately 70 degrees to the left from the runway heading with the left main just outside the runway lights and the right main inside the lights. The impact took out the nose gear and damaged the nose section of the aircraft."

The U.S. Government Alaska Airport Supplement, under Kivalina, Airport Remarks, states, in part: Unattended. CAUTION: RWY condition not monitored, recommend visual inspection prior to using.

The Kivalina Airport is owned by the State of Alaska, and runway maintenance is delegated to the City of Kivalina via a contractual agreement. The portion of the contract agreement pertaining to snow removal is appended.

And in Selawik, still sitting out in the mud, is an Everts Air Fuel DC-6 that ran off the end of rwy 27 in 1992.

NTSB Identification: ANC92LA043 .
The docket is stored on NTSB microfiche number 47641.
Nonscheduled 14 CFR Part 125: 20+ Pax,6000+ lbs
Accident occurred Tuesday, March 03, 1992 in SELAWIK, AK
Probable Cause Approval Date: 5/26/1993
Aircraft: DOUGLAS DC-6B, registration: N151
Injuries: 1 Minor, 2 Uninjured.
THE HEAVILY LOADED FUEL TANKER LANDED WITH AN APPROXIMATE 3 KNOT TAILWIND, OVER RAN THE DEPARTURE END OF THE RUNWAY, AND CAME TO A STOP ON A FROZEN RIVER. THE LAST TWO THIRDS OF THE 3,150 FT LONG GRAVEL RUNWAY WAS COVERED WITH ICE. THE CREW STATED THAT THE PROPELLERS EITHER FAILED TO GO INTO REVERSE, OR WERE SLOW IN REVERSING, TO ASSIST IN STOPPING. EXAMINATION REVEALED THAT ALL PROPELLER BLADES WERE IN THE REVERSED POSITION. OUTSIDE AIR TEMPERATURE WAS MINUS 30 TO MINUS 35 DEGREES F. THE AIRPLANE PERFORMANCE CHART USED TO CALCULATE THE LANDING DISTANCE WAS FOR 'CONCRETE RUNWAYS'. STOPPING DISTANCE WAS NOT PREDICATED ON THE USE OF REVERSE PROPELLER THRUST. POST ACCIDENT CALCULATIONS, USING THE SAME CHART, FOUND THE ESTIMATED LANDING DISTANCE NEEDED FOR THE ACCIDENT FLIGHT TO BE 100 TO 200 FT MORE THAN THE LENGTH OF THE RUNWAY.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

THE PILOT'S INADEQUATE PRE FLIGHT PLANNING AND DISREGARDING THE AIRCRAFT PERFORMANCE DATA. CONTRIBUTING FACTORS WERE THE EXTREME OUTSIDE AIR TEMPERATURES, THE ICY RUNWAY, AND THE TAILWIND.

thanks gump. Those were good enough stories and they make for good lawn art. John

I don't know how to do the picture load-up mumbo jumbo, but this link should give a bigger picture.

On a Cessna 182 the Battery is behind the baggage compartment. But it would like to be warmed up.
