|
|
What’s the formula for time [min] if distance [NM] and GS [kts] are known? |
time [min] = ( distance [NM] / GS [kt] ) * 60 |
Tip: if approximating in head, multiply distance by 60 first, then divide e.g.: 10 NM * 60 = 600 600 / 105 [kt] = approx. 6 [min] |
|
QDR |
is MAGNETIC bearing of the AIRCRAFT from the station |
e.g. VOR radial |
|
QTE |
is TRUE bearing of the AIRCRAFT from the station |
|
|
QDM |
is MAGNETIC bearing of the STATION from the aircraft |
e.g. magnetic heading to fly TO the VOR |
|
QUJ |
is TRUE bearing of the STATION from the aircraft |
|
|

|
|
What’s ASI behaviour on climb when Pitot tube is blocked? |
ASI behaves like ‘altimeter’, speed increases on climb, speed decreases on descend. |
|
|
What’s ASI behaviour on descend when Pitot tube is blocked? |
ASI behaves like ‘altimeter’, speed increases on climb, speed decreases on descend. |
|
|
What’s ASI behaviour on climb when static vent is blocked? |
During the climb Pitot static pressure is less and decreasing than vent static pressure, the Pitot dynamic pressure is decreased by this difference, ASI underreads. |
|
|
What’s ASI behaviour on descend when static vent is blocked? |
During the descend Pitot static pressure is greater than vent static pressure, the Pitot dynamic pressure is increased by this difference, ASI overreads- DANGER! |
|
|
ASI over-reads in what TWO scenarios? |
blocked Pitot tube on climb (icing, left Pitot tube cover) blocked static vent on descend (icing) |
|
|
If an aircraft is at 2000 ft and the VOR transmitter (VHF) has an elevation of 250 ft, what is the line of sight range in NM? |
range = 1.25 x [ sqrt( height of aircraft ft) + sqrt( elevation of transmitter ft) ] = 76 NM |
|
|
Convert 1 NM to meters? |
1NM = 1852 m |
|
|
Convert 1000 ft to metres? |
1000 ft = 304.8 m |
|
|
