What is the note in UH 60 ATM Apter seven regarding the digitization of the cockpit?
Note. Digitization of the crew compartments has expanded and redefined the lines of responsibility for each crewmember. The ability for either crewmember to perform most aircraft/system functions from his crew station breaks down the standard delineation of duties and has added capabilities in training and in combat. This could mean that during an unforeseen event, one crewmember may attempt to resolve the situation himself rather than seek assistance from the other crewmember. It is essential for the PC to brief specific duties before stepping into the aircraft. Effective sharing of tasks relies on good crew coordination and information management.
With engine bleed air on, the available torque per engine is reduced as follows: The engine anti-ice on _____. Cockpit/gunner heater on: Reduce torque available by______. Anti-ice and cockpit/gunner heater on: Reduce maximum torque available by _____
20% Q
5%Q
25%Q
The engine anti-ice will increase dual engine fuel flow_____. Cockpit and gunner heat will increase fuel flow______. With anti-ice and cockpit/gunner heat on fuel flow will increase_____
100 pounds/hour
20 lbs./hour
120 pounds/hour
Increased rotor efficiency IGE is caused by what two factors?
Induced Flow 1-106. Proximity of the helicopter to the ground interrupts airflow under the helicopter by altering the velocity of induced flow. Induced flow velocity is reduced when closer to the ground, which in turn, increases AOA, reduces the amount of induced drag, allows a more vertical lift vector, and increases rotor system efficiency.
Vortex Generation 1-107. When operating close enough to a surface for ground effect to exist, the downward and outward flow of air tends to restrict vortex generation. The smaller vortexes result in the outboard portion of each blade becoming more efficient and reduce overall system turbulence caused by ingestion and recirculation of the vortex pattern.
While starting the aircraft for a DAY VFR flight it is discovered that the #4 MFD will only display the PFD and Engine Instrument Caution Advisory System (EICAS) pages and the #2 MFD is inoperative. Is it still legal to fly the aircraft?
Yes it is still legal. 1,3, and 4 need to be operational. A MFD is considered operational if the PFD and EICAS pages can be displayed and provide the required information
What is the purpose of the Main Rotor Head Lead Stop installed on the forward edge of each elastomeric bearing endplate?
Prevent damage to the spindles during rotor brake operation when installed
