Navigation Systems Flashcards
LPV approaches not authorized when glideslope is?
Between 3.51° and 4.49°
If planning to fly an RNP-AR approach other than the procedure indicated on the release, accomplish one of the following prior to takeoff:
*Call Dispatch and request amended release
*Complete the following:
-Verify destination or alternate approach is listed in the RNP-AR Authorized Procedures for applicable database cycle.
-Ensure FMS database is current and equipment listed in Required operational Equipment for RNP-AR Approach table is not affected by the MEL.
-Ensure RNP 0.3 landing minima is depicted on approach chart.
-Verify missed approach RNP is not less than 1.0
-Ensure availability of a local altimeter setting
-complete RAIM prediction for ETA
Inertial Reference System (IRS) is what?
Honeywell Laseref V micro using digital ring laser gyros to compute attitude, heading, angular rates, linear accelerations, vertical velocity and present position information.
The IRS interfaces with what aircraft systems:
- Electronic flight instrumentation system (EFIS)
- Weather Radar
*Automatic flight control system (AFCS)
*Flight Data Recorder (FDR)
*Terrain awareness warning system (TAWS)
*Traffic alert & collision avoidance system (TCAS)
*Stall protection system (SPS)
*Aircraft fuel system
*Flight management system (FMS)
Realignment in flight for the IRS if a power interruption or a transient system fault occurs will take how long?
10 to 20 minutes. The alignment time may exceed 20 minutes if any of the following conditions are present:
*No change in heading during alignment
*No changes in acceleration during alignment
*An east to west flight trajectory such that the IRUs’ sensed rotational rates in inertial space is nearly equal to zero.
How many IRS’s does the 650 have?
Three
What powers the number 1 (Left) CDU?
BATT bus
What powers the number 2 (Right) CDU?
DC bus 2
What powers the number 3 CDU?
DC essential
