MH60T Trivia #301-325
This trivia series distills over 20 years of flight manual study into 500+ focused questions and answers, posted in 25 question sets. It’s not a substitute for the manual, but rather an aid to facilitate study and strengthen airmanship. During your review, ask yourself: How is this operationally relevant? Do I need to memorize it, or just be familiar with it? Should I review more on this topic?
301. Q: Below 50 knots, the autopilot maintains what?
A: Pitch and roll (attitude hold) and heading.
302. Q: With RAD ALT Hold on and RAD ALT failure, what happens?
A: BAR ALT will engage automatically.
303. Q: With BAR ALT Hold on and a BAR ALT failure, what will happen?
A: Altitude hold is lost.
304. Q: Where and when does the RADALT switch pulse widths? What effect can this have on the helicopter?
A: Pulse widths switch at 500′ (+/- 50′). If RADALT hold is engaged at 500′ agl, the AFCS will climb and descend the helo +/-50′ from the selected altitude (the same thing can happen at 1750′ but RADALT hold probably won’t work at that altitude).
305. Q: With Altitude Hold on, what torque value is the AFCS limit when making collective changes?
A: 116%
306. Q: With a malfunctioning torque indicating system, what is the impact on the AFCS?
A: Since AFCS limits collective based on torque, erroneous high torque will limit power available to the AFCS, therefore do not perform auto approach hover or departure (warning).
307. Q: With hover altitudes set below 40’, what will auto approach do?
A: Approach to a coupled hover at 40’, followed by a vertical descent to a selected altitude
308. Q: Lowest altitude you can crank down to?
A: 30′ AWL.
309. Q: TCAS can track how many targets?
A: 35.
310. Q: TCAS can display how many targets?
A: 8.
311. Q: TCAS tracks targets within what relative altitude?
A: +/- 9000’.
312. Q: TCAS may not display targets located where?
A: 8° aft and above the aircraft.
313. Q: TCAS bearing accuracy is what?
A: From 7:30 to 4:30 +/- 30°. From 4:30 to 7:30 +/- 45°.
314. Q: A vertical arrow next to a TCAS symbol indicates what?
A: Target is climbing or descending at greater than or equal to 500 fpm.
315. Q: A solid yellow dot on the TCAS means what?
A: Traffic advisory (TA). Traffic’s Track will intercept yours within 15-30 seconds or the traffic is within .55nm, +/- 800’. “Traffic, traffic” audio will be heard.
316. Q: A solid blue diamond on the TCAS means what?
A: Proximity advisory (PA). Traffic within 4nm, +/- 1200’, but not a TA.
317. Q: A hollow blue diamond on the TCAS means what?
A: Other traffic (OT) which is in the selected display range but is not a TA or PA.
318. Q: 4 display modes of TCAS determine what kind of traffic is displayed?
A: Other Traffic, TAs and PAs are always displayed.
319. Q: What are the 3 TCAS modes and their parameters?
A: 1. Normal Mode, OT within +/- 2700’ is displayed. 2. Above Mode, OT from -2700’ to + 9000’ is displayed. 3. Below Mode, OT from -9000’ to + 2700’ is displayed.
320. Q: What warning is associated with TCAS?
A: Do not attempt evasive maneuvers based solely on TCAS information.
321. Q: How is TCAS range adjusted?
A: TCAS range is changed on the PFD or NAV by selecting either the up or down arrows associated with the bezel keys located on the right side of the MFD. If WXR is also selected as an overlay, the TCAS range will be slaved to the range of the radar.
322. Q: Weight on wheels automatically puts TCAS on standby how long after landing?
A: 24 seconds.
323. Q: The fire detector sensors detect what?
A: Infrared radiation.
324. Q: What is infrared radiation caused by?
A: Fire or extreme overheating.
325. Q: How many fire detectors are there?
A: 5 – 2 in each engine (fire wall and deck) and 1 in the APU compartment (fire wall).
