Daily Questions - General 2024 Review Solution What is ETL and when will it occur? - ANS-Effective Translational Lift is the point at which the aircraft will out run it's own rotor wash and move into clean, undisturbed air. 16-24 knots The HYD PRESSURE LO light illuminates when pressure is at: - ANS-1000 PSI Decreasing Pressure IAW TO 1H-1(T)H-1, What is Vortex Ring State and when is it most likely to occur? - ANS-An uncommanded rate of descent caused by the aircraft rotor inducing a vortex ring as it settles into its own down wash. Most likely to occur when descent rates exceed 800 feet per minute during vertical descents initiated from a hover and steep approaches at less than 40 knots. What are the engine oil pressure limits? - ANS-Red Band - 0-25 psi White Band - 25-80 psi Green Band - 80-100 psi Red Band - 100 psi What is the type and power rating (capability) of the TH-1H engine? - ANS-T53-L-703 Take-Off power (TOP) - 1800SHP Max Cont. power (MCP) - 1500SHP When will you get the RPM Light and Audio? - ANS-Low Rotor RPM - 93% +/- 2% or Loss of Nr and Nf Tachometers The 90-degree gearbox provides how much gear reduction to the tail rotor? - ANS-2.6 to 1 How do you check if the Hydraulic Filter has been bypassed? - ANS-Check the LRB ("Little Red Button") through the inspection window located above the access door on the forward face of the transmission bulkhead. The 20 MINUTE FUEL caution light will illuminate at what fuel state? - ANS-Between 130lbs to 240lbs What is the caution associated with the slope limits? - ANS-Caution is to be exercised for slopes greater than 5 degrees, since rigging, loading, and wind conditions may result in contacting the control stops What is the ADC and what does it do? - ANS-Air Data Computer, calculates key air data such as altitude, airspeed, height deviation (VVI), and temperature What is the maximum airspeed when torque exceeds 88%? - ANS-80 KIAS What are the weight limitations for the TH-1H? Maximum Gross Weight Maximum Gross Weight for towing Maximum Allowable Weight for External Cargo Weight Distribution Limitations - ANS-10,500 pounds (11,200 for external loading) 9,500 pounds
