CY2010	us-gaap	Revenue Recognition General Principles RevenueRecognitionGeneralPrinciples	Revenue Recognition. Sales under government and commercial fixed-price contracts and government fixed-price-incentive contracts are recorded at the time deliveries are made or, in some cases, on a percentage-of-completion basis. Sales under cost-reimbursement contracts are recorded as work is performed. Sales for elevators, escalators, installation and modernization contracts are accounted for under the percentage-of-completion method. Losses, if any, on contracts are provided for when anticipated. Loss provisions on original equipment contracts are recognized to the extent that estimated inventoriable manufacturing, engineering, product warranty and product performance guarantee costs, as appropriate, exceed the projected revenue from the products contemplated under the contractual arrangement. For new commitments, we generally record loss provisions at the earlier of contract announcement or contract signing except for certain requirements contracts under which losses are recorded upon receipt of the purchase order. For existing commitments, anticipated losses on contracts are recognized in the period in which losses become evident. Products contemplated under contractual arrangement include products purchased under contract and, in the large commercial engine business, future highly probable sales of replacement parts required by regulation that are expected to be purchased subsequently for incorporation into the original equipment. Revenue projections used in determining contract loss provisions are based upon estimates of the quantity, pricing and timing of future product deliveries. Losses are generally recognized on shipment to the extent that inventoriable manufacturing costs, estimated warranty costs and product performance guarantee costs, as appropriate, exceed revenue realized. Contract accounting requires estimates of future costs over the performance period of the contract as well as estimates of award fees and other sources of revenue. These estimates are subject to change and result in adjustments to margins on contracts in progress. The extent of progress toward completion on our long-term commercial aerospace equipment and helicopter contracts is measured using units of delivery. In addition, we use the cost-to-cost method for elevator and escalator sales, installation and modernization contracts in the commercial businesses. For long-term aftermarket contracts, revenue is recognized over the contract period in proportion to the costs expected to be incurred in performing services under the contract. We review our cost estimates on significant contracts on a quarterly basis, and for others, no less frequently than annually or when circumstances change and warrant a modification to a previous estimate. Adjustments to contract loss provisions are recorded in earnings upon identification.

In the commercial businesses, revenue is generally recognized on a straight line basis. In the aerospace businesses, revenue is generally recognized in proportion to cost.

CY2010	utx	Financing Receivable Allowance For Credit Losses Factors That Influenced Managements Judgment FinancingReceivableAllowanceForCreditLossesFactorsThatInfluencedManagementsJudgment	Factors considered in assessing collectability and risk include, but are not limited to, examination of credit quality indicators and other evaluation measures, underlying value of any collateral or security interests, significant past due balances, historical losses, and existing economic conditions.
CY2010	utx	Financing Receivable Allowance For Credit Losses Policy For Uncollectible Amounts FinancingReceivableAllowanceForCreditLossesPolicyForUncollectibleAmounts	Uncollectible long-term receivables are written-off when collection of the indebtedness has been pursued for a reasonable period of time without collection; the customer is no longer in operation; or judgment has been levied, but the underlying assets are not adequate to satisfy the indebtedness.
CY2010Q4	utx	Financing Receivable FinancingReceivable	535000000	USD
CY2010	utx	Financing Receivable Allowance For Credit Losses Risk Characteristics FinancingReceivableAllowanceForCreditLossesRiskCharacteristics	Economic conditions and air travel influence the operating environment for most airlines, and the financial performance of our aerospace businesses is directly tied to the economic conditions of the commercial aerospace and defense industries. Additionally, the value of the collateral is also closely tied to commercial airline performance and may be subject to exposure of reduced valuation as a result of market declines.
CY2010	utx	Financing Receivable Credit Quality Additional Information FinancingReceivableCreditQualityAdditionalInformation	We determine credit ratings for each customer in the portfolio based upon public information and information obtained directly from our customers. We conduct a review of customer credit ratings, published historical credit default rates for different rating categories, and multiple third party aircraft value publications as a basis to validate the reasonableness of the allowance for losses on these balances quarterly or when events and circumstances warrant. The credit ratings listed below range from “A” which indicates an extremely strong capacity to meet financial obligations and the receivable is either collateralized or uncollateralized, to “D” which indicates that payment is in default and the receivable is uncollateralized.
