Narrative:
I was the PF on a cargo MD11 going into subic, philippines. At 7000 ft MSL as we were approaching sba VOR, coming from manila, we were told to descend to 6000 ft. I set the altitude and started down. We then got a 1000 ft radar altimeter aural warning but we had no actual radar altimeter to verify this with, so assumed it false. We sometimes get these at cruise altitude so nothing seemed terribly wrong. Then about 6800-6900 ft we got a 'too low, terrain' GPWS warning. I immediately firewalled power, disconnected autoplt/autothrottles and climbed. Now we got into another situation. I was too aggressive on a very light (300000 pounds) aircraft and we got probably 40 degree nose high and then some left bank. I recovered from this mildly unusual attitude and accomplished an uneventful landing at subic. This was probably a false alarm, but we obviously had to react. But my reaction, or really overreaction, leads me to believe we need simulator twice a yr. There is lots of talk about going just once a yr and I have always believed this to be unwise. This episode further confirms my belief. Constant practice of sits is needed to maintain sharpness and safety.
Original NASA ASRS Text
Title: FO OF AN MD11 TOOK EVASIVE ACTION AND CLBED IN RESPONSE TO A GPWS WARNING RESULTING IN A VERY HIGH ACFT PITCH ATTITUDE DUE TO THE FULL THROTTLE LIGHT ACFT CLB.
Narrative: I WAS THE PF ON A CARGO MD11 GOING INTO SUBIC, PHILIPPINES. AT 7000 FT MSL AS WE WERE APCHING SBA VOR, COMING FROM MANILA, WE WERE TOLD TO DSND TO 6000 FT. I SET THE ALT AND STARTED DOWN. WE THEN GOT A 1000 FT RADAR ALTIMETER AURAL WARNING BUT WE HAD NO ACTUAL RADAR ALTIMETER TO VERIFY THIS WITH, SO ASSUMED IT FALSE. WE SOMETIMES GET THESE AT CRUISE ALT SO NOTHING SEEMED TERRIBLY WRONG. THEN ABOUT 6800-6900 FT WE GOT A 'TOO LOW, TERRAIN' GPWS WARNING. I IMMEDIATELY FIREWALLED PWR, DISCONNECTED AUTOPLT/AUTOTHROTTLES AND CLBED. NOW WE GOT INTO ANOTHER SIT. I WAS TOO AGGRESSIVE ON A VERY LIGHT (300000 LBS) ACFT AND WE GOT PROBABLY 40 DEG NOSE HIGH AND THEN SOME L BANK. I RECOVERED FROM THIS MILDLY UNUSUAL ATTITUDE AND ACCOMPLISHED AN UNEVENTFUL LNDG AT SUBIC. THIS WAS PROBABLY A FALSE ALARM, BUT WE OBVIOUSLY HAD TO REACT. BUT MY REACTION, OR REALLY OVERREACTION, LEADS ME TO BELIEVE WE NEED SIMULATOR TWICE A YR. THERE IS LOTS OF TALK ABOUT GOING JUST ONCE A YR AND I HAVE ALWAYS BELIEVED THIS TO BE UNWISE. THIS EPISODE FURTHER CONFIRMS MY BELIEF. CONSTANT PRACTICE OF SITS IS NEEDED TO MAINTAIN SHARPNESS AND SAFETY.
