A lighting the runway with under 1000 ft to go, the pilots breathed a sigh of relief. However, they underestimated their climb from the lift off point and, with the sluggish rate of climb, the saddle ridge across the departure path suddenly became a dangerous obstacle they might not clear.

Since the 7,600-foot main runway was unavailable, I ran the numbers for the lightly-loaded Cardinal for takeoff on the 4,400-foot cross runway. The first half of the takeoff was on a slight downgrade, acceleration seemed OK, and we broke ground about the same time as we crossed the longer Runway 21 Left/3 Right.

Helium contributes only about 60 percent of the lift—the shape of the balloon forms a giant wing, providing the rest. READ MORE: Airlines and Pilots Don’t See Eye to Eye on Autonomous Flights Aerodynamic lift and vectored thrust come from two pairs of ducted propellers running on kerosene-powered engines, mounted outside the main hull.

ATC asked if the aircraft required the full length of the runway and the crew confirmed that they did. The aircraft accelerated along the runway and reached V1, the take-off decision speed, of 155 knots normally. The aircraft lifted off at 08:08:39 UTC. At 08:07:33, the aircraft was cleared for take-off.

It shows the helicopter flying normally, aligned to the runway, and then begin a gentle climb. The pilot told the airport tower controller that he may need the runway. The controller asked the pilot to report when two miles out and to expect runway 28. The indicated airspeed had fallen below 65 knots and was still decreasing.

Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. These include lift, propeller thrust, and engine combustion. This increased density increases airflow over the wings, generating more lift. Fewer air molecules result in less dense air, which means less lift.

Drawbacks: For takeoff, a tailwind significantly increases the required runway length and results in a shallower climb angle. Effects: It will try to push your aeroplane sideways off the runway centreline. Can cause sudden losses or gains in indicated airspeed (IAS), directly affecting lift.
