Aeroplanes that take-off and prepare to land at much sharper angles than they do at present are among Airbus’ latest industry forecasts.
The European jet-maker made the predictions in its Smarter Skies vision for air travel in 2050.
The firm said the moves could minimise noise, reduce fuel emissions and potentially shorten flight times.
It added that shorter runways could be used, helping reduce the amount of space airports need.
That marks a contrast with the firm’s recent launch of the A380 “sumperjumbo” which – along with Boeing’s older 747 design – stretches minimum runway length requirements in the opposite direction.
