Reference the Radar Altimeter, The dial and pointer will be displayed up to a value of _______feet. At values beyond _________, the dial and pointer will be removed. Radar altitude digital readout values will remain but only up to an upper limit of 1500 feet. The readouts are removed above _______feet and return below ________feet.
1050, 1050, 1500, 1450
Discuss the purpose, functions, and capabilities of the Multifunction Slew Controller
It provides control of the MFD cursor and provides cursor activation, menu navigation and selection.
The controls and functions are: Slew controller (controls cursor), Select control, Menu Control and Mode Control
Discuss the three cursor modes of the Digital Map System?
- Free- The cursor can be moved anywhere on the display via the active slew button
- Bezel- The bezel cursor symbol travels around the bezel keys based on directional inputs.
- Menu- allows selection of menu items by means of a captive cursor control. The cursor automatically switches to menu cursor mode upon activation of a menu.
During single engine ground operation with the collective full down NP/NR may indicate _____, even when the engine speed trim is increased to the maximum setting. This is a __________ characteristic, and may be observed more frequently during hot weather. Raising the collective slightly (approximately 1⁄2 inch) will bring the NP/NR to 100%.
99%, normal
What are your VFR weather minimums for Class G Airspace Day and Night below 1200’ AGL?
Day: 1/2 mile clear of clouds.
Night: 1 mile clear of clouds.
Define Dynamic Rollover and the conditions required for it to occur?
A helicopter is susceptible to a lateral-rolling tendency called dynamic rollover. Dynamic rollover can occur on level ground as well as during a slope or crosswind landing and takeoff. Three conditions are required for dynamic rollover— pivot point, rolling motion, and exceed critical angle.
What is the Note associated with Slope Landing Limitations?
Because of the flat profile of the main transmission and forward location of both transmission oil pumps, transmission oil pressure will drop during nose-up slope operations. At slope angle of 10°, an indicated oil pressure of 30 to 35 psi is normal; and at a 15° slope angle, a pressure in the range of 10 to 15 psi is normal due to pitching of the helicopter.
According to Chapter 8 of TM 1-1520-280-10, when should a roll-on landing be used?
roll-on landing may be used when the helicopter will not sustain a hover; to avoid hovering in snow or dust; if tail rotor control is lost; or when operating with one heavy external tank.
