1.3 APU start

1.3.1 Set APU mode switch to [ЗАПУСК]

Veryfy [APU GEN][ГЕНЕР. АИ-9В] is switched off.

Set DC voltage selector switch to position related current power supply type ( External or Battery), set [APU START MODE][РОД РАБОТ] switch to [START][ЗАПУСК] ( lower )position. Press [START APU][ЗАПУСК] button for 2-3 seconds, turn on stopwatch and wait until [AUTOMAT WORKING][АВТОМАТ ВКЛЮЧЕН] lights up. When APU reaches normal RPM, lamps [APU RPM][ОБОРОТЫ АИ-9В НОРМАЛЬН.], [AUTOMAT WORKING][АИ-9В РАБОТ.] and [APU OIL PSI][ДАВЛЕН. МАСЛА НОРМАЛЬН] will light up.

1.3.2 While start up monitor following values:

- exhaust gas temperature must not exceed 880°C;

- DC currents must be higher than 18 volts;

- normal oil pressure is indicated by [APU OIL PSI][ДАВЛЕН. МАСЛА НОРМАЛЬН] light. At the beginning of APU start blinking of this lamp can occur;

- time needed to reach idle RPM shouldn't exceed 20 seconds;

- Maximum time for starter engagement is 30 seconds, check that [AUTOMAT WORKING][АИ-9В РАБОТ.] lamp extinguishes after that amount of time.

While DISS-15 mode selector switch in Test 1 position press [DISS counters on][ВКЛ.] button on indicators panel (for 5 minutes counter [FWD][ВПЕРЕД] should show 11.3 km);

- check drift and forward velocity indicator – set [DISS DRIFT TEST][К-Р] in [TEST][К] position. Forward velocity indicator value should be (306±3.5) km/h, drift angle (15±1)*.

- check “Memory” mode – set mode selector switch to [Memory][ПАМЯТЬ] position. Forward velocity indicator should change not more than ±9 km/h, drift angle – less than ±3*. Lamp [П] on drift indicator will light up at same time. Set [DISS DRIFT TEST][К-Р] switch to [Operate][Р] position;

- check map-case operation for movement of caret when [MAP-CASE POWER][ВКЛ.-АВТ.-ОТКЛ.] switched in [ON][ВКЛ.] position and [DISS counters on][ВКЛ.] button on counters panel is pressed. After tests are finished set [MAP-CASE POWER][ВКЛ.-АВТ.-ОТКЛ.] to [OFF][ОТКЛ.].

Set DISS-15 mode selector switch to [OPERATE][РАБОТА] position.


Appendix A: Fuel System

Mi24v fuel 2.png

Fuel is distributed to the Engines from the corresponding engine Feed tanks (1,2). Should one pump fail Both engines will be fed from the remaining tank. If both pumps have failed fuel will be gravity fed to the engine, however any maneuvering must be avoided. Land ASAP in that case!

The Feed tanks are fed by both main tanks (4,5) Should one transfer pump fail, fuel will be supplied via the other tank. Switch on Cross-feed (8) to use the trapped fuel in the failed tank.

WARNING: Should both pumps fail (e.g. due to ELEC FAIL) Only fuel in the Feed tanks is usable. Remaining flight time in that case is ~ 5 minutes!

The Main Reservoir Tank has no pumps and gravity feeds directly into Tank 4.

External Fuel is not implemented (yet!).
