BI / checkride Flashcards
Define
- Land as soon as practical
- Land as soon as possible
- Land immediately
When IMC
Land as soon as practical:same as VMC
“The landing site and duration of flight is at the…”
Land as soon as possible + immediately:
1) Try to reach VMC and continue VFR
2) If VMC is not possible - land as nearest IFR airfield with a published INST approach
AR 95-1
Rules regarding visibility reduction as helicopter pilot ?
- May be reduced 50% but not less than 1/4
- Only if pilot briefing doesn’t specify otherwise
- Only for CAT A as a helicoper
- NOT for “copter” approaches
CAT A = 90 KIAS
What’s WX void time ?
An hour and 30 min - provided the a/c has not departed
When may pilot use GPS at both alternate and destination approach ?
When the RNAV system has TSO 145/146 equipment (UH72 has it)
You must use circling/RNAV planning minimums
When can you fly SVFR ?
What is SVFR minimums?
Airspace: B,C,D,E
Need: ATC clearance
1/2 SM vis + COC (unless airfield has higher minimum)
When can you fly below MDA/DA ?
1 One of the following must be visible/in sight:
- Treshhold of runway
- Approach lights
- Markings that ident. landing area
2 The a/c must be n a position from which a safe approach and landing can be made
AR 95-1
IFR GPS approach & missed apprach procedures ?
sequencing of GPS + if on a copter approach
1. Procedures from approved
2. P verify that GPS begins to sequence when in terminal area prior to IAF
3. If GPS doesn’t sequence before IAF = pilots request alternate procedures / post IAF = missed approach
4. Copter missed approaches will be flown as 70 KIAS
EFB rules
Electronic flight bag
- There must be no outdates pubs on the device
- 10 % battery per flight hour
- minimum 50% battery to commence flight
Must bring paper pubs if:
- Both pilot are not operating on the same EFB softwear (ie. foreflight)
- If only one pilot is using an EFB
- There is a password on the device
To excute an IFR flight, what restrictions is there to the AFCS ?
Must be in level 4 and fully operative
IFR 2 way RDO failure procedure ?
1 Execute good judgement
2 Try the guard frequency, other radios, and try to tune in on a NAVAID ATC might try to communicate through it
3 Squak 7600
4 Try to obtain VMC
5 Select route using (AVE-F) and altitude using (MEA)
Continue flight to approach and adhere to EFC and ETA times. (holding if necessary)
Name the 3 space based and 3 ground based approach we can perform in the UH72
Space
- LNAV (NMS)
- LPV (GLS)
- LP (GLS)
Ground
- VOR (VOR)
- LOC (ILS)
- ILS (ILS)
If an ILS approach failes it reverts into a ?
LOC approach
What is full deflection on the CDI
In VOR mode
Full deflection = (at O nr. 2)
10 º
What is full deflection on the CDI
In LOC mode
Full deflection = (at O nr. 2)
2.5 º
What is full deflection on the CDI
In NMS mode
3 types
Full deflection = (at O nr. 2)
Enroute: 2 NM
Terminal: 1 NM
Approach: 1-0.3 NM
When does the “approach mode” light appear in the cockpit?
45 degrees of the FAF
(the FAF must be the next waypoint)
AFCS
What’s the pupose of the stability augmentation system (SAS) ?
- Provides a stable platform for autopilot functions
- Dampens disturbances
(dynamic and atmospheric influences)
AFCS
Describe the AFCS loop
Brains (sensors and computation units)
Muscles (actuators)
The brains meassures relevant data, computations units analyze it and sends signals to the actuators. The actuators converts signal to the flight controls.
AFCS
What’s the difference between
SAS & trim ?
SAS: You can’t see the inputs, has limited control autority, uses SEMAs
Trim: You can see the inputs, has 100% control autority, uses parallel actuators
AFCS
What’s the control authority of the SAS ?
Level 3 and level 2 ?
Level 3 = All 5 SEMAS used
11% - 12% - 18%
Pitch - Yaw - Roll
Level 2 = Only 3 SEMAS used
6% - 12% - 9%
Pitch - Yaw - Roll
AFCS
Which sensors do the UH 72 have for the AFCS ?
- FOG
- AHRS
- ADC
- OAT
- Sensor 1+2
- Magnetometer 1+2
What sensored are used in digital SAS ?
Level 3
AHRS + FOGs
What’s the purpose of the SAS/AP cut ?
Disengages AFCS in the event of a flight control malfunction
AFCS
What does the “FOGs” meassure ?
Fiber obtic gyros
Meassures turning rate
