UH-60M - Ops Limits (Ch. 5) - changes

Question 1

EXCEEDING OPERATIONAL LIMITS

Any time an operational limit is exceeded, an appropriate entry shall be made on DA Form __________. Entry shall state what limit or limits were____________, ____________, ________________________, and any additional data that would aid maintenance personnel in the maintenance action that may be required. The helicopter shall not be _____________ until corrective action is taken.

Answer 1

Any time an operational limit is exceeded, an appropriate entry shall be made on DA Form 2408-13-1. Entry shall state what limit or limits were exceeded, range, time beyond limits, and any additional data that would aid maintenance personnel in the maintenance action that may be required. The helicopter shall not be flown until corrective action is taken.

Question 2

ENGINE INSTRUMENT CREW ALERTING SYSTEM (EICAS) AND PFD POWER POD COLOR CODES.

Red and Yellow striped tapes and red readouts indicate the limit ______________________________.

Yellow tapes and readouts indicate_________.

Green tapes and readouts indicate the______.

Answer 2

Red and yellow striped tapes and red readouts indicate the limit above or below which continued operation is likely to cause damage or shorten component life.

Yellow tapes and readouts indicate the range when special attention should be given to the parameter the instrument represents.

Green tapes and readouts indicate the normal operating range of the parameter the instrument represents.

Question 3

ROTOR BRAKE/GUST LOCK LIMITATIONS

Operating an engine against the gust lock is ____ .

Rotor brake shall not be applied with engine(s) operating and rotor turning except during an emergency stop. Maximum rotor speed for emergency rotor brake applications is __%NR.

Routine stops will be with engine(s) off, NR below __% and with ___–___ psi applied to stop the rotor in not less than __seconds.

Minimum rotor brake pressure for engine start is ___psi. Maximum rotor brake pressure for engine start is _______ psi.

Use of the rotor brake with engine(s) operating is restricted to _____ and _____ engine starts and operations at _____ only.

Single and dual engine starts and operation at ___ with rotor brake on are not time limited.

Answer 3

Operating an engine against the gust lock is prohibited.

Rotor brake shall not be applied with engine(s) operating and rotor turning except during an emergency stop. Maximum rotor speed for emergency rotor brake ap- plications is 76% NR.

Routine stops will be with engine(s) off, NR below 40% and with 150-180 psi applied to stop the rotor in not less than 12 seconds.

Minimum rotor brake pressure for engine start is 450 psi. Maximum rotor brake pressure for engine start is 690 psi.

Use of the rotor brake with engine(s) operating is restricted to single and dual engine starts and operations at IDLE only.

Single and dual engine starts and operation at IDLE with rotor brake on are not time limited.

Question 4

MAIN TRANSMISSION MODULE LIMITATIONS

If oil pressure is not steady during steady state forward flight or in a level hover, or if oil pressure is steady but under _____ psi, make an entry on the appropriate maintenance form. Sudden pressure drop (more than ____ psi) without fluctuation requires an entry on the appropriate maintenance form.

Answer 4

If oil pressure is not steady during steady state forward flight or in a level hover, or if oil pressure is steady but under 45 psi, make an entry on the appropriate maintenance form. Sudden pressure drop (more than 10 psi) without fluctuation requires an entry on the appropriate maintenance form.
