DG & Airspeed Flashcards
What pretakeoff check should be made of a vacuum driven heading indicator in preparation for an IFR flight?
After 5 minutes, set the indicator to the magnetic heading of the aircraft and check for proper alignment after taxi turns.
Pre-Takeoff HI: After 5, set HI, check after taxi turns.
(Refer to figure 146. The DG shows a right turn. OAT is -1*C.) Identify the system that has failed and determine a corrective action to return the airplane to straight-and-level.
Static/pitot system is BLOCKED; lower the nose and level the wings to level flight attitude by use of attitude indicator, apply power, and turn on the pitot heat to unblock.
DG=RT Turn; Corrective action: Pitot/Static system BLOCKED
(Refer to figure 251.) When lined up for takeoff on RWY 18, the compass and heading indicator should say a heading of about
185*.
RWY 18 about 185*
(Refer to figure 251.) When lined up for takeoff on RWY 27, the compass and heading indicator should say a heading of about
275*.
RWY 27 about 275*
(Refer to figure 251.) When lined up for takeoff on RWY 4, the compass and heading indicator should say a heading of about
050*.
RWY 4 about 050*
You receive the following ATC clearance ”Cessna 733WS, cleared for takeoff RWY 04, fly runway heading winds 090 at 15 gust 25.” (magnetic heading 044*) Which direction should you fly?
Magnetic heading 044 with no wind correction.
Magnetic Heading 044* = Magnetic heading 044*
No Wind
The proper way to check a heading indicator before IFR flight is to set the heading indicator to the magnetic compass and
Ensure the instrument functions properly during taxi.
Pre-Takeoff HI: Ensure it functions proper during taxi
The glide slope and localizer are centered, but the airspeed is too fast. Which should be adjusted initially?
Power only.
Which instrument serves as a primary back up in case your airspeed indicator fails?
Tachometer.
