Why Pilots Rapidly Juxtapose the Throttle During Carrier Landings

When landing on the decks of U.S. Navy aircraft carriers, pilots perform a technique known as Controlled Descent. This involves rapidly adjusting the throttle to maintain the desired glide slope and airspeed. Given the short and precise landing area, any deviation can have serious consequences. In this article, we will explore the reasons behind this technique and the importance of throttle manipulation during carrier landings.

Compensating for Wind Conditions

During approach, pilots must deal with varying wind conditions. These can include wind shear, which can significantly affect the approach path. By adjusting the throttle, pilots can compensate for changes in airspeed and maintain a stable descent profile. This is crucial for ensuring a controlled and safe landing. As indicated in the data, pilots must keep their airspeeds consistent to prevent sudden changes in altitude or speed that could lead to an unstable landing.

Avoiding Stall and Maintaining Lift

A stall can be a significant risk, especially as pilots approach slower speeds required for landing. Throttle modulation helps prevent this by keeping the engine power responsive. By maintaining the correct engine power, pilots can ensure they have enough thrust to avoid losing lift. The key is to be able to augment power if needed to regain lift and prevent stalling. As a result, pilots can maintain a consistent and controlled descent, important for a safe landing.

Engaging the Arrestor Hook

Engaging the arrestor wire is another critical aspect of carrier landings. The throttle adjustments can help pilots reach the correct power setting for a safe touchdown and successful hook engagement. Landing with too much power can result in excessive acceleration and difficulty in securing the wire. Conversely, too little power can result in a slow, unsure approach. Pilots must be precise to ensure a smooth engagement of the arresting cable, which is essential for a safe landing.

Feedback from the Landing Signal Officer (LSO)

The LSO plays a crucial role in providing real-time feedback to pilots during the landing approach. This feedback helps pilots make necessary adjustments to the throttle to achieve the optimal landing configuration. The LSO's guidance is instrumental in ensuring a safe and successful landing, as highlighted by the precision required in carrier landings. Pilots rely on these adjustments to fine-tune their approach, ensuring they have the right speed and attitude when they touch down.

Managing Energy During Carrier Landings

Landing on a moving deck requires precise energy management. Initially, the jet engine operates at reduced power, and as the plane approaches the deck, the throttle is rapidly adjusted to bring the engine back up to full power. This is crucial in case the aircraft misses the arresting wire. The pilot must add fuel in short bursts to limit the increase in kinetic energy from the thrust. By doing so, they ensure that when the throttle is slammed forward, the engine has instant response, preventing excessive deceleration and maintaining their kinetic energy at a manageable level. This technique is essential for ensuring a smooth and safe landing on the carrier's short deck.

In conclusion, the rapid juxtaposition of the throttle during carrier landings is a vital technique that ensures a safe and successful landing. From compensating for wind conditions to avoiding stalling, and engaging the arrestor hook, the imperative role of throttle manipulation cannot be overstated. Coupled with real-time feedback from the LSO, pilots can achieve the optimal landing configuration, making carrier landings one of the most challenging yet rewarding aspects of naval aviation.
