We quickly learned that power management was a skill necessary to survive our deployment. The racetrack patterns plc running fire tactics we utilized were necessary due to insufficient power to hover and to increase our own survivability.
A valuable lesson learned from this deployment is that units should focus early on power management issues and train accordingly so that they ppf prepared when deployed. While en route to Khowst, we crossed a snow-covered mountain at 11, MSL.
This cell always contained at least one of the unit instructor pilots.
Performance planning was a critical part of each mission. We arrived in Afghanistan near the end of January and were based out of Kandahar International Airport.
Each mission required performance planning for altitudes, temperatures, and gross weights that were much higher than we normally operate. By the end of April, the temperature at Kandahar was nearing degrees Fahrenheit. We had already conducted numerous missions to include Operation Anaconda. During our missions in Afghanistan, we had two aviators assigned to our performance-planning cell.
AH Operations In Afghanistan
Within three weeks of our arrival, our missions started taking us to higher and higher ah-64s. We adapted to this environment well, but were fortunate to have a wealth of experienced aviators in our company. Kandahar is approximately 3, feet mean sea level MSL and can be characterized as high desert.
I slowly increased the power until I drooped the rotor and then decreased the collective.
On a daily basis, we had power available to hover out of ground effect OGE. We knew that it would not be long before power was a luxury that we would not have. Our first mission took us from Kandahar to Bagram Airbase to refuel and then on to pppc eastern city of Khowst.
During the winter months at Kandahar, our aircraft performed well. During the deployment, we were exposed to a wide range of temperatures, a variety of flight environments, and altitude extremes that we had never operated in before. The terrain is relatively flat with rolling sand dunes 10 miles west and a mountain range approximately 15 miles to the north.
