The impacts of global warming on the mechanics of commercial aircraft can be quite significant. Here are a few potential impacts:

1. Changes in Atmospheric Density: As global temperatures rise, the density of the atmosphere can decrease. This can impact the lift generated by an aircraft's wings, potentially requiring longer runways for takeoff or reducing the maximum payload an aircraft can carry.

2. Increased Turbulence: Some research suggests that global warming could lead to an increase in clear-air turbulence, which can cause damage to aircraft and make flights less comfortable for passengers.

3. Heat Restrictions: Aircraft performance can be significantly impacted by high temperatures. If temperatures at airports around the world continue to rise, there could be more frequent delays or cancellations due to heat restrictions.

4. Sea Level Rise: Many major airports are located near coastlines. If sea levels continue to rise, these airports (and their associated infrastructure, could be at risk.

5. Changes in Wind Patterns: Global warming can lead to changes in wind patterns, which can impact flight times, fuel efficiency, and even the safety of flights.

6. Increased Maintenance: Higher temperatures can lead to increased wear and tear on aircraft, potentially requiring more frequent maintenance.

Here are some relevant papers on the impacts of global warming on commercial aircraft:

1. Unprecedented Impacts of Aviation Emissions on Global Environmental and Climate Change Scenario: dx.doi.org/10.1007/s407…, by Farooq Sher, David Raore, J. Klemeš, P. M. Rafi-ul-Shan, Martin Khzouz, K. Marintseva, O. Razmkhah. This study investigates the role of aviation emissions in global warming. It provides data on global air traffic and growth rate, air traffic in different continents, total global CO2 emissions of different airlines, direct and indirect emissions, air traffic in various UK airports, and fuel-efficient aircraft.

2. Global tourism, climate change and energy sustainability: assessing carbon reduction mitigating measures from the aviation industry: dx.doi.org/10.1007/s116…, by W. Leal Filho, Artie Ng, Ayyoob Sharifi, J. Janová, P. Özuyar, Chinmai Hemani, G. Heyes, Dennis Njau, I. Rampasso. This paper explores the implications of a changing climate for the global tourism business and its intertwining global aviation industry that operates in a self-regulatory environment.

3. Estimating the Impact of Global Warming on Aircraft Takeoff Performance in China: dx.doi.org/10.3390/atmo…, by Weiguo Yuan, P. Dai, Mengxiang Xu, W. Song, Peng Zhang. This study investigates the impact of global warming on aircraft takeoff performance in 53 airports in China by combining observational data and CMIP6 climate projections.

4. Innovative Box-Wing Aircraft: Emissions and Climate Change: dx.doi.org/10.3390/SU13…, by A. Tasca, V. Cipolla, K. Abu Salem, M. Puccini. This paper discusses the introduction of the PrandtlPlane, an innovative box-wing aircraft, and its expected reduction of climate change impact in all the source regions considered.
