Which two instruments are used to confirm two positive rates of climb for gear retraction?

• A. Altimeter and VSI
• B. Airspeed Indicator and Altimeter
• C. Attitude Indicator and Heading Indicator
• D. VSI and Attitude Indicator

Answer: (A)

When you’re preparing to retract the landing gear, you want two independent indications that you’re actually climbing. The vertical speed indicator gives you the rate of climb directly, while the altimeter confirms you’re gaining altitude by showing a rising altitude value. Using both provides redundancy and a clear confirmation that the aircraft is in a positive climb, which is the condition required before retracting gear. Other instruments don’t show climbing rate or altitude change, so they aren’t reliable for this purpose.
